• Aging skin. Although there is interest in using oral or topical acai to prevent aging skin, there is insufficient reliable information about the clinical effects of acai for this purpose.
• Athletic performance. It is unclear if oral acai is beneficial for improving athletic performance. Details: Preliminary clinical research in amateur cyclists shows that consuming 400 grams of pasteurized acai pulp daily for 15 days prevents oxidative damage and decreases levels of blood lactate during exercise by 28% when compared with placebo. Consuming acai pulp also seems to increase anaerobic threshold intensity, but does not improve maximum workload or measures of exertion, when compared to baseline (102860).
• Erectile dysfunction (ED). Although there is interest in using oral acai for ED, there is insufficient reliable information about the clinical effects of acai for this condition.
• Hypercholesterolemia. Although there is interest in using oral acai for hypercholesterolemia, there is insufficient reliable information about the clinical effects of acai for this condition.
• Metabolic syndrome. Although there is interest in using oral acai for metabolic syndrome, there is insufficient reliable information about the clinical effects of acai for this condition.
• Obesity. It is unclear if oral black seed is beneficial for improving metabolic indices in overweight individuals. Details: In overweight individuals, preliminary clinical research shows that consuming 100 mg of acai pulp (Sambazon Acai Smoothie Pack, Sambazon Inc.) twice daily for one month reduces fasting glucose and total cholesterol levels when compared with baseline. However, no effect was seen on levels of low density lipoprotein (LDL) cholesterol, triglycerides, high density lipoprotein (HDL) cholesterol, or blood pressure (17731). The validity of these findings is limited by the lack of a comparator group.
• Osteoarthritis. Although there is interest in using oral acai for osteoarthritis, there is insufficient reliable information about the clinical effects of acai for this condition.
• Tinnitus. It is unclear if oral acai is beneficial for chronic tinnitus. Details: A small clinical study in adults with unilateral or bilateral chronic tinnitus, with either normal hearing or mild hearing loss, shows that taking dried acai pulp extract 100 mg daily for 3 months decreases tinnitus discomfort when compared with baseline (107846). However, the validity of this finding is limited by the lack of statistical comparison to the placebo group, which reported a numerically similar improvement in tinnitus discomfort. More evidence is needed to rate acai for these uses.

• Acne. Although there has been interest in using topical apple cider vinegar for acne, there is insufficient reliable information about the clinical effects of apple cider vinegar for this condition.
• Athletic performance. It is unclear if oral apple cider vinegar is beneficial for improving endurance during exercise. Details: Preliminary clinical research in a small number of healthy male athletes shows that drinking apple cider vinegar 500 mL one-hour prior to an endurance cycling test does not improve endurance capacity, as measured by respiratory exchange rate, heart rate, or blood levels of ammonia, glucose, or lactate, when compared with a commercial sports drink (103225). It is unknown if apple cider vinegar would improve endurance when compared with a placebo control.
• Atopic dermatitis (eczema). Although there has been interest in using topical apple cider vinegar for eczema, there is insufficient reliable information about the clinical effects of apple cider vinegar for this condition.
• Cognitive function. Although there has been interest in using oral apple cider vinegar to improve cognitive function, there is insufficient reliable information about the clinical effects of apple cider vinegar for this use.
• Coronavirus disease 2019 (COVID-19). Although there has been interest in using oral apple cider vinegar for COVID-19, there is insufficient reliable information about the clinical effects of apple cider vinegar for this use.
• Dandruff. Although there has been interest in using topical apple cider vinegar for dandruff, there is insufficient reliable information about the clinical effects of apple cider vinegar for this condition.
• Dental plaque. It is unclear if topical apple cider vinegar prevents the accumulation of dental plaque. Details: A small clinical study in children aged 3-6 years with cerebral palsy shows that applying apple cider vinegar 5% to their teeth daily for 6 months reduces the accumulation of dental plaque when compared with manual tooth brushing without dental paste (111228). However, the validity of these findings is limited by a lack of blinding and poor study methodology.
• Depression. Although there has been interest in using oral apple cider vinegar for depression, there is insufficient reliable information about the clinical effects of apple cider vinegar for this condition.
• Diabetes. It is unclear if oral apple cider vinegar is beneficial for improving glucose control in patients with type 2 diabetes; evidence is conflicting. Details: Two meta-analyses of mainly lower-quality clinical trials in a variety of populations (i.e., healthy, overweight, or obese individuals or those with type 2 diabetes) show that taking apple cider vinegar daily for up to 12 weeks reduces fasting blood glucose (FBG) levels by about 8-21 mg/dL, glycated hemoglobin (HbA1c) by 0.5%-0.9%, and total cholesterol by 6-7 mg/dL when compared with control (e.g., water, another beverage, no beverage, or restricted calorie diet). There was no effect on levels of low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, insulin, or on measures of insulin resistance. However, in sub-group analyses limited to patients with type 2 diabetes, the effect of apple cider vinegar on FBG or HbA1c levels is conflicting (106284,112355). Of note, both meta-analyses include studies with heterogeneous populations, varied dosages, and different durations that limit the interpretation of these pooled results. Additionally, a very small clinical study shows that taking apple cider vinegar 20 grams with a meal increases postprandial insulin sensitivity and reduces postprandial flux in insulin levels in patients with insulin resistance, but not those with type 2 diabetes, when compared with placebo (17614). It is unclear if the formulation of apple cider vinegar alters its effects. One small crossover study in healthy adults found a modestly greater reduction in postprandial glucose with the use of liquid apple cider vinegar (providing 1.25 grams acetic acid) when compared with apple cider vinegar whole tablets or crushed tablets (providing 1.5 grams acetic acid) or water alone (106285). Larger studies are needed to confirm this finding.
• Dyspepsia. Although there has been interest in using oral apple cider vinegar for dyspepsia, there is insufficient reliable information about the clinical effects of apple cider vinegar for this condition.
• Gastroparesis. It is unclear if oral apple cider vinegar is beneficial for gastroparesis. Details: A very small clinical study shows that taking apple cider vinegar 30 mL daily worsens the gastric emptying rate in patients with type 1 diabetes and gastroparesis when compared with drinking water (17609).
• Gingivitis. It is unclear if topical apple cider vinegar prevents the development of gingivitis. Details: A small clinical study in children aged 3-6 years with cerebral palsy shows that applying apple cider vinegar 5% to the teeth daily for 6 months reduces gingivitis scores when compared to baseline, with results comparable to manual tooth brushing without dental paste at the end of the study period (111228). However, the validity of these findings is limited by a lack of blinding and poor methodology.
• Herpes zoster (shingles). Although there has been interest in using topical apple cider vinegar for shingles, there is insufficient reliable information about the clinical effects of apple cider vinegar for this condition.
• Hyperlipidemia. Although there has been interest in using oral apple cider vinegar for hyperlipidemia, there is insufficient reliable information about the clinical effects of apple cider vinegar for this condition.
• Impaired glucose tolerance (prediabetes). Although there has been interest in using oral apple cider vinegar for prediabetes, there is insufficient reliable information about the clinical effects of apple cider vinegar for this condition.
• Insect bite. Although there has been interest in using topical apple cider vinegar for insect bites, there is insufficient reliable information about the clinical effects of apple cider vinegar for this condition.
• Intestinal parasite infection. Although there has been interest in using oral apple cider vinegar for intestinal parasite infections, there is insufficient reliable information about the clinical effects of apple cider vinegar for this condition.
• Kidney stones (nephrolithiasis). It is unclear if oral apple cider vinegar reduces the risk for kidney stones. Details: Some population research suggests that the consumption of fermented vinegar can reduce the risk for kidney stones (97311). However, there is currently no clinical evidence confirming this association, or any studies specifically evaluating the use of apple cider vinegar for this purpose.
• Leg cramps. Although there has been interest in using oral apple cider vinegar for leg cramps, there is insufficient reliable information about the clinical effects of apple cider vinegar for this condition.
• Obesity. It is unclear if oral apple cider vinegar is beneficial for obesity. Details: A small clinical study in overweight and obese adults shows that taking apple cider vinegar 15 mL twice daily for 12 weeks along with a calorie-restricted diet helps control appetite and modestly reduces body weight, body mass index (BMI), and hip girth when compared with a restricted calorie diet alone. Taking apple cider vinegar along with dieting also appears to increase high-density lipoprotein (HDL) cholesterol levels and decrease triglyceride levels, but not low-density lipoprotein (LDL) cholesterol levels, when compared to dieting alone (97310).
• Osteoarthritis. Although there has been interest in using oral apple cider vinegar for osteoarthritis, there is insufficient reliable information about the clinical effects of apple cider vinegar for this condition.
• Pharyngitis. Although there has been interest in using oral apple cider vinegar for pharyngitis, there is insufficient reliable information about the clinical effects of apple cider vinegar for this condition.
• Rhinosinusitis. Although there has been interest in using oral apple cider vinegar for rhinosinusitis, there is insufficient reliable information about the clinical effects of apple cider vinegar for this condition.
• Sunburn. Although there has been interest in using topical apple cider vinegar for sunburn, there is insufficient reliable information about the clinical effects of apple cider vinegar for this condition.
• Vaginal candidiasis. Although there has been interest in using topical apple cider vinegar for vaginal candidiasis, there is insufficient reliable information about the clinical effects of apple cider vinegar for this condition.

• Constipation. Oral Bacillus coagulans seems to be beneficial for constipation. Details: Clinical research in individuals with mild intermittent constipation shows that taking B. coagulans SNZ 1969 (CTCBIO, Inc.) 1 billion colony-forming units (CFUs) daily for 8 weeks reduces colonic transit time, increases the number of weekly complete spontaneous bowel movements, and improves bowel discomfort when compared with placebo. Colonic transit time was reduced by at least 25% in 58% of patients taking B. coagulans, compared with 32% of patients taking placebo (107613). Other clinical research in patients with functional constipation shows that taking B. coagulans Unique IS2 (Unique Biotech Limited) 2 billion CFUs daily for 4 weeks modestly increases the number of bowel movements and reduces abdominal pain and pain with defecation when compared with placebo. Also, 98% of patients achieved normal stool consistency, compared with 74% of those taking placebo (107612). Adding lactulose 10 grams to this regimen increases stool frequency when compared with placebo, but not when compared with lactulose alone. However, normal stool consistency was achieved earlier and by more patients in those taking lactulose plus B. coagulans when compared with lactulose alone. The combination was also more beneficial for reducing defecation pain, abdominal pain, and sensations of incomplete evacuation (107614). Also, a small clinical study in adults with constipation-dominant functional bowel disorders shows that taking a specific supplement containing B. coagulans 1 billion CFUs twice daily for 4 weeks modestly improves abdominal pain and abdominal distention, as well as discomfort and effort during defecation, when compared with baseline (104232). However, the validity of the findings in this study is limited by the lack of a comparator group.
• Irritable bowel syndrome (IBS). Oral Bacillus coagulans seems to be beneficial for IBS. Details: Clinical research in adults with diarrhea-predominant IBS shows that taking B. coagulans daily for 56-90 days improves quality of life and decreases bloating, nausea, vomiting, abdominal pain, and stool frequency when compared with placebo. Improvements in headache, anxiety, and constipation have also been shown (92730,92735,92740,105169). In addition, meta-analyses show that taking B. coagulans reduces overall symptom, straining, and/or abdominal pain severity when compared with placebo (107594,110866). In one study, taking B. coagulans for 80 days resulted in no symptoms in 63% of individuals, compared with only 21% of those taking placebo (105169). Doses used in some of this clinical research have included a specific B. coagulans MTCC5856 product (Lactospore, Sabinsa Corporation) 2 billion colony-forming units (CFUs) daily for 90 days (92730), another specific B. coagulans product (GanedenBC30, Ganeden Biotech Inc.) 300 million to 2 billion CFUs daily for 8 weeks (92735,92740), B. coagulans LBSC (Advanced Enzyme Technologies Ltd.) 2 billion CFUs three times daily for 80 days (105169), or B. coagulans Unique IS2 2 billion CFUs daily for 8 weeks (110866). Other clinical research in adults with IBS shows that taking a specific combination product (Colinox, DMG Italia SRL) containing B. coagulans and simethicone after each meal three times daily for 4 weeks improves bloating and discomfort, but not pain, when compared with placebo (92726).

• Antibiotic-associated diarrhea. Although there has been interest in using oral Bacillus coagulans for antibiotic-associated diarrhea, there is insufficient reliable information about the clinical effects of B. coagulans for this condition.
• Athletic performance. It is unclear if oral Bacillus coagulans is beneficial for athletic performance. Details: A small clinical trial shows that taking an inactivated B. coagulans GBI-30, 6086 product (Staimune, Kerry, Inc) 1 billion cells daily for 2 weeks does not improve jump power or muscle endurance when compared with placebo (107610). This study might not have been adequately powered to detect differences between groups. A larger study in resistance-trained males shows that taking B. coagulans Unique IS-2 2 billion colony-forming units daily for 60 days in combination with 20 grams of an 80% whey protein concentrate modestly improves some measures of power and muscle strength when compared with taking whey protein alone. However, some measures of strength were not improved, and there was no effect on maximum oxygen consumption, muscle hypertrophy, or body composition (110878).
• Cancer. Although there has been interest in using oral Bacillus coagulans for cancer prevention, there is insufficient reliable information about the clinical effects of B. coagulans for this purpose.
• Cirrhosis. Oral Bacillus coagulans has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in adults with liver cirrhosis who are at increased risk for developing spontaneous bacterial peritonitis (SBP) shows that taking a combination of B. coagulans, Enterococcus faecalis, Clostridium butyricum, and Bacillus mesentericus three times daily, in conjunction with norfloxacin for 6 months, does not reduce the risk of developing SBP when compared with norfloxacin alone (92731).
• Clostridioides difficile infection. Although there has been interest in using oral Bacillus coagulans for C. difficile infection, there is insufficient reliable information about the clinical effects of B. coagulans for this purpose.
• Depression. Although there has been interest in using oral Bacillus coagulans for depression, there is insufficient reliable information about the clinical effects of B. coagulans for this condition.
• Diabetes. Oral Bacillus coagulans has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in patients with type 2 diabetes shows that taking B. coagulans GBI-30, 6086 (GanedenBC30) 100 billion CFUs, Lactobacillus acidophilus 1 billion colony-forming units (CFUs), Lacticaseibacillus rhamnosus 10 billion CFUs, and fructo-oligosaccharides 500 mg daily for 12 weeks modestly reduces fasting blood glucose and insulin and improves measures of insulin resistance when compared with placebo. There was no effect on plasma lipids (107731).
• Diarrhea. It is unclear if oral Bacillus coagulans is beneficial for acute diarrhea or diarrhea-dominant functional bowel disorders. Details: Clinical research in infants 6-24 months of age with acute diarrhea of various causes shows that taking B. coagulans 120 million colony-forming units (CFUs) twice daily for up to 5 days in conjunction with oral rehydration solution does not decrease duration, frequency, or volume of diarrhea when compared with oral rehydration solution and placebo (92738). However, a small clinical study in adults with acute diarrhea shows that taking a specific supplement (Lactic Acid Bacillus) containing B. coagulans 2 billion CFUs, three times daily for 7 days, reduces diarrhea and improves abdominal pain when compared with placebo (100853). Preliminary clinical research in adults with diarrhea-dominant functional bowel disorders shows that taking a specific supplement containing B. coagulans 1 billion CFUs twice daily for 4 weeks reduces abdominal pain, abdominal distention, discomfort and effort during defecation, and the number of stools classified as diarrhea when compared with baseline (104232). The validity of these findings is limited by the lack of a comparator group.
• Dyspepsia. It is unclear if oral Bacillus coagulans is beneficial for dyspepsia. Details: Several small studies show that B. coagulans can improve symptoms of dyspepsia (104231,104232,104233,107611). In one study, 1 billion colony-forming units (CFUs) were taken twice daily for 4 weeks, resulting in an improvement in abdominal pain and abdominal distention when compared with placebo (104232). Some studies have used B. coagulans in combination with other probiotics. In adults with functional dyspepsia, taking a combination of B. coagulans MY01 and Bacillus subtilis MY02 as 1.25 billion CFUs each twice daily for 8 weeks improves postprandial distress scores of at least 0.7 in 48% of patients, compared with only 20% of those taking placebo (107611). A small clinical study in older adults aged 55-75 years with indigestion, abdominal pain, and flatulence shows that taking a probiotic syrup containing B. coagulans 500 million CFUs with digestive enzymes (alpha amylase 25 mg, pepsin 10 mg, and lipase 1.5 mg) 5 mL twice daily for 5 days reduces symptoms of dyspepsia when compared with placebo (104233). Also, a small study in adults with non-specific gastrointestinal discomfort shows that taking a specific combination supplement (SNZ TriBac, Sanzyme Biologics) containing B. coagulans SNZ 1969, Bacillus clausii SNZ 1971, and B. subtilis SNZ 1972, 2 billion CFUs daily for 30 days, decreases self-reported symptoms of burping, belching, and sour taste when compared with placebo (104231). It is unclear if these effects are due to B. coagulans, other ingredients, or the combinations.
• Flatulence. It is unclear if oral Bacillus coagulans is beneficial for flatulence. Details: Clinical research in children aged 6-8 years shows that taking B. coagulans GBI-30, 6086 (GanedenBC30, Ganeden, Inc.) 1 billion colony-forming units (CFUs) daily for 3 months modestly decreases the incidence of flatulence when compared with taking placebo (107615). However, preliminary clinical research in patients with postprandial intestinal gas-related symptoms shows that taking a specific combination supplement (Digestive Advantage Gas Defense Formula, Ganeden Biotech) containing this same strain of B. coagulans and an enzyme blend daily for 4 weeks does not improve bloating or gas when compared with placebo (92736).
• Gingivitis. Although there has been interest in using oral Bacillus coagulans for gingivitis, there is insufficient reliable information about the clinical effects of B. coagulans for this condition.
• Helicobacter pylori. It is unclear if oral Bacillus coagulans is beneficial for H. pylori. Details: In patients with H. pylori, preliminary clinical research shows that taking B. coagulans (Donghai Pharmaceutical Co Ltd) 1050 mg three times daily for 8 weeks results in a 20% eradication rate 1-2 weeks after treatment. This was as effective as taking Clostridium butyricum 1050 mg twice daily, alone or in combination with B. coagulans (105168). This study is limited by lack of blinding and the lack of a placebo group. Also, it is unclear how B. coagulans compares to standard H. pylori eradication treatments.
• HIV/AIDS. Although there has been interest in using oral Bacillus coagulans for HIV/AIDS, there is insufficient reliable information about the clinical effects of B. coagulans for this condition.
• Hypercholesterolemia. Although there has been interest in using oral Bacillus coagulans for cholesterol reduction, there is insufficient reliable information about the clinical effects of B. coagulans for this purpose.
• Inflammatory bowel disease (IBD). Although there has been interest in using oral Bacillus coagulans for IBD, there is insufficient reliable information about the clinical effects of B. coagulans for this purpose.
• Necrotizing enterocolitis (NEC). It is unclear if oral Bacillus coagulans is beneficial or safe for NEC prevention. Details: Preliminary clinical research in infants with a gestational age of less than 33 weeks or a very low birth weight shows that taking B. coagulans 350 million colony-forming units daily until hospital discharge does not reduce the risk of NEC or death when compared with placebo. However, taking B. coagulans reduced the incidence of feeding intolerance in these newborns (92733). The US Food and Drug Administration (FDA) warns that preterm infants given probiotics are at risk of serious infections caused by the bacteria or fungi contained in probiotics due to cases reported in very preterm or very low birth weight infants under 1000 grams (111610). Also, The American Academy of Pediatrics does not support the routine administration of probiotics to preterm infants, particularly those with a birth weight below 1000 grams, due to conflicting data on safety and efficacy and potential for harm in this vulnerable population (111608).
• Nonalcoholic fatty liver disease (NAFLD). It is unclear if oral Bacillus coagulans is beneficial for NAFLD. Details: Preliminary clinical research in adults with NAFLD shows that taking 1 capsule containing B. coagulans 1 billion colony-forming units plus 400 mg inulin for 8 weeks may be beneficial for treating inflammation associated with NAFLD when compared with placebo. However, this combination did not improve lipid profiles or glycemic indices. Inulin was used in this study as a prebiotic to ensure bacterial growth in the gut lumen (104230).
• Postoperative ileus. It is unclear if oral Bacillus coagulans is beneficial for postoperative ileus. Details: A small clinical study in patients undergoing gynecological laparoscopic surgery shows that taking B. coagulans TBC169 105 million or 175 million colony-forming units the night before surgery, and then every 8 hours starting 8 hours after surgery, reduces time to first flatus by up to 10 hours when compared with placebo. There were also modest reductions in the rates of postoperative gastrointestinal adverse events such as nausea, vomiting, distension, and ileus. However, there was no difference in time to first defecation or length of hospital stay (110879).
• Rheumatoid arthritis (RA). It is unclear if oral Bacillus coagulans is beneficial for RA. Details: Preliminary clinical research in adults with RA shows that taking B. coagulans GBI-30, 6086 (GanedenBC30, Ganeden Biotech Inc.) 2 billion colony-forming units daily for 60 days, in conjunction with standard therapy, reduces overall pain when compared with placebo. However, it does not reduce the number of painful or swollen joints or improve activities of daily living (92734).
• Rotaviral diarrhea. It is unclear if oral Bacillus coagulans is beneficial for rotaviral diarrhea. Details: Preliminary clinical research in newborns shows that taking B. coagulans 100 million colony-forming units daily for one year reduces the incidence of acute rotaviral diarrhea. Taking B. coagulans decreases the incidence of diarrheal episodes by around 5 per year and reduces duration of diarrhea by around 3 days per episode when compared with placebo. However, taking B. coagulans does not reduce the occurrence of mild to moderate dehydration (92729).
• Small intestinal bacterial overgrowth (SIBO). Oral Bacillus coagulans has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in adults with SIBO who were previously treated for 3 weeks with broad spectrum antibiotics shows that taking a specific probiotic product (Lactol, Bioplus Life Sciences Pvt. Ltd.) containing B. coagulans spores and fructo-oligosaccharides twice daily on 15 days per month for 6 months, in conjunction with minocycline, modestly decreases stomach pain and flatulence (91145).
• Travelers' diarrhea. Although there has been interest in using oral Bacillus coagulans for travelers' diarrhea, there is insufficient reliable information about the clinical effects of B. coagulans for this condition.
• Upper respiratory tract infection (URTI). It is unclear if oral Bacillus coagulans is beneficial for URTI prevention. Details: Clinical research in children aged 6-8 years shows that taking B. coagulans GBI-30, 6086 (GanedenBC30, Ganeden, Inc.) 1 billion colony-forming units (CFUs) daily for 3 months modestly decreases the incidence of some URTI symptoms, including nasal congestion, bloody nasal mucus, itchy nose, and hoarseness, but not others such as dry cough and sore throat, when compared with placebo (107615). More evidence is needed to rate Bacillus coagulans for these uses.

• Diabetes. Although there is interest in using oral coconut for diabetes, there is insufficient reliable information about the clinical effects of coconut for this condition.
• Hypercholesterolemia. It is unclear if oral coconut is beneficial for lowering cholesterol levels; the available research is conflicting. Details: Preliminary clinical research in patients with moderately elevated serum cholesterol levels shows that consuming corn flakes with 15% or 25% dietary fiber from coconut flakes (prepared with coconut flour) for 2 weeks reduces total cholesterol by about 7% to 11% and low-density lipoprotein (LDL) cholesterol by about 9% to 11% when compared with baseline (26295). However, population research suggests that people who consume large amounts of coconut have higher cholesterol levels when compared with those who do not (26558). These conflicting results may be due to the type of coconut being consumed. For example, coconut contains coconut oil, which has been associated with increased cholesterol levels in some research (12361,17940). On the other hand, coconut flour is prepared from coconut residue after extraction of milk; this byproduct residue is defatted and contains a high percentage of water-soluble dietary fiber (26197).
• Lichen Planus. There is limited evidence on the use of topical coconut cream in adults with oral lichen planus. Details: Preliminary clinical research findings suggest that topical coconut 50% cream may reduce lesion size, burning sensation, and pain level over a time period of 60 days when compared with baseline. Coconut cream appears to be similarly effective to the standard treatment clobetasol propionate 0.05% ointment in the treatment of oral lichen planus. The study is limited by unclear statistical analysis, small sample size, and a short follow-up period (110713).
• Obesity. Although there is interest in using oral coconut for weight loss, there is insufficient reliable information about the clinical effects of coconut for this condition. More evidence is needed to rate coconut for these uses.

• Androgenic alopecia. Topical coconut water has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: In individuals with self-perceived hair loss, preliminary clinical research shows that applying a combination leave-in product containing coconut water modestly improves hair growth rate and density, and reduces hair thinning when compared with baseline. The product contained coconut water solids (Cococin), Indian gooseberry (Saberry), gamma-L-glutamyl-selenomethionine (Peptiselect), and other ingredients; a once daily application of 3.5 mL in females and 2 mL in males was used for 3 months (105353).
• Athletic performance. It is unclear if oral coconut water is beneficial for athletic performance. Details: Preliminary clinical research in males shows that drinking coconut water 10 mL/kg of body mass, taken in seven divided doses every 10 minutes prior to exercise in the heat, increases cycling time to exhaustion by about 2 seconds when compared with drinking plain water (95139). Other clinical research shows that drinking coconut water equivalent to 125% of estimated bodily fluid loss over a period of one hour following exercise-induced dehydration improves subsequent treadmill performance to a similar extent as a sports drink containing carbohydrates and electrolytes (95126). However, drinking coconut water during or following exercise may not be any more effective than drinking plain water (95126,95136).
• Diarrhea-related dehydration. It is unclear if oral coconut water is beneficial for diarrhea-related dehydration. Details: Preliminary reports suggest that drinking coconut water might improve hydration in children with mild diarrhea (17666). But there is no reliable evidence that it is any more effective than other beverages for this purpose.
• Exercise-induced dehydration. It is unclear if oral coconut water is beneficial for exercise-related dehydration. Details: Preliminary clinical research shows that drinking coconut water following exercise is effective for rehydration. It appears to be comparable to sports drinks containing carbohydrates and electrolytes, especially if the coconut water is enriched in sodium (17678,17679,95126,95136). However, coconut water may not be any more effective than drinking plain water (17678). Coconut water equivalent to 120% to 125% of estimated bodily fluid loss has been consumed over a period of 1-2 hours following exercise (17678,17679,95126). Alternatively, 1 liter of coconut water consumed in 4 divided doses has been used during 60 minutes of exercise (95136). Drinking coconut water before exercise might help prevent dehydration from occurring. A small clinical study shows that drinking coconut water 10 mL/kg of body mass, taken in seven divided doses every 10 minutes before exercising in the heat, reduces urine output after exercise without affecting sweat rate when compared with plain water. This suggests that coconut water may have a greater hydration capacity than plain water (95139). However, additional research is needed to confirm this hypothesis.
• Hypertension. It is unclear if oral coconut water is beneficial for hypertension. Details: Preliminary clinical research in adults with hypertension shows that drinking coconut water 300 mL twice daily for up to 2 weeks modestly lowers systolic and diastolic blood pressure when compared with baseline (17680). Any effects of coconut water on blood pressure may be due to its potassium content. Potassium concentrations range from 35-82 mEq/L (17669,95138). More evidence is needed to rate coconut water for these uses.

• Allergic rhinitis (hay fever). Oral live or heat-killed Lacticaseibacillus paracasei seems to improve some symptoms of allergic rhinitis in adults and children. Details: Clinical research in adults with persistent allergic rhinitis due to grass pollen despite treatment with loratadine shows that taking L. paracasei LP-33 as 2 billion colony-forming units (CFUs) daily for 5 weeks can improve quality of life by almost 18% when compared with placebo. The improvement in quality of life appears to be related to improvements in eye-related symptoms, but not nasal symptoms (90242). In children with perennial allergic rhinitis due to dust mites, taking L. paracasei LP-33 10 billion CFUs daily for 30 days improves quality of life related to overall symptom severity or level of bother by 28% and 23%, respectively, when compared to placebo. However, quality of life related specifically to nasal and eye-related symptoms was not improved when compared with placebo (107532). In children ages 2-5 years with allergic rhinitis, clinical research shows that taking fermented milk (Danone) containing L. paracasei DN-114 011 10 billion CFUs daily does not increase the time free from rhinitis episodes, the mean duration of episodes, or the cumulative number of episodes, when compared with taking a control milk. However, the number of episodes was reduced between months 3-9. The fermented milk was made with the yogurt cultures Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus (112512). Heat-killed L. paracasei has also been investigated. One clinical trial in adults with chronic allergy symptoms shows that taking heat-killed L. paracasei IJH-SONE68 1040 mg or 500,000 cells daily for 12 weeks modestly improves self-reported symptoms, including frequencies of sneezing and blowing, watery eyes, and head dullness, when compared with taking placebo. There was no effect on nasal congestion or itchy eyes (111939). Also, clinical research in children aged 5 years and older with perennial allergic rhinitis due to dust mites shows that taking heat-killed L. paracasei LP-33 10 billion cells daily for 30 days improves quality of life related to overall symptom severity or level of bother by 18% and 22%, respectively, when compared with placebo. Efficacy was not inferior to live L. paracasei LP-33 (107532).
• Atopic dermatitis (eczema). Oral live Lacticaseibacillus paracasei, alone or in combination with other probiotics, seems to be beneficial for the treatment of atopic dermatitis in infants and children and for preventing atopic dermatitis when provided to the infant after exposure during pregnancy. Small clinical trials suggest that heat-killed L. paracasei does not seem to be beneficial for the treatment of atopic dermatitis. Details: In children aged 1-18 years, clinical research shows that taking L. paracasei 2 billion colony-forming units (CFUs) daily, alone or with Limosilactobacillus fermentum 2 billion colony-forming units (CFUs) daily each, for 3 months modestly reduces symptoms of atopic dermatitis when compared with placebo (98440). However, another clinical trial shows that administering formula containing lyophilized L. paracasei CNCM I-2116 to infants aged 3-6 months does not reduce atopic dermatitis severity or the prevalence of atopic dermatitis after 12 weeks of treatment (90256). Heat-killed L. paracasei has also been investigated. In adults treated with conventional topical corticosteroid and tacrolimus, a small clinical trial shows that taking heat-killed L. paracasei K71 200 billion cells daily for 12 weeks does not improve skin symptom severity, quality of life, or use of topical medication, when compared with taking placebo (111947). Also, in infants ages 4-30 months with atopic dermatitis, clinical research shows that, in addition to topical fluticasone propionate cream, taking heat-treated L. paracasei GM-080 daily for 16 weeks does not further improve symptoms when compared with using the topical fluticasone propionate cream alone (102406). Other clinical research has investigated the effects of L. paracasei in combination with other probiotics for the PREVENTION of atopic dermatitis. A combination of L. paracasei, Ligilactobacillus salivarius, Bifidobacterium animalis subsp. lactis, and Bifidobacterium bifidum, a total of 10 billion CFUs daily provided from 36 weeks' gestation and then to the infant until age 6 months, reduces the prevalence of atopic dermatitis at age two by approximately 60% (90234). Similar findings occurred in clinical research investigating the effect of L. paracasei ST11 and B. longum BL999 (ST11+BL999) for the last 2 months of pregnancy and first 2 months of breastfeeding (90234,90285).
• Common cold. A combination of Lacticaseibacillus paracasei and Lactiplantibacillus plantarum seems to be beneficial for reducing the incidence or severity of the common cold. The effects of L. paracasei alone are unclear. Details: Clinical research in healthy individuals shows that taking an acidified milk drink providing L. paracasei (L. casei 431) 1 billion colony-forming units (CFUs) daily for 21 days before and after receiving the seasonal influenza vaccination does not affect the number, duration, or severity of common cold or influenza-like illness episodes when compared with taking placebo. However, there was a modest reduction in the duration of illness 4-6 weeks after vaccination (111937). L. paracasei has also been examined in combination with L. plantarum. Clinical research shows that taking L. plantarum HEAL 9 (DSM 15312) and L. paracasei 8700:2 (DSM 13434) (Probi Defendum, Probi AB) 1 billion CFUs daily for 12 weeks reduces the incidence of the common cold by about 12% and reduces the number of symptomatic days from 8.6 to 6.2 when compared with placebo (17119). Additional clinical research in adults at increased risk of a common cold shows that taking this same combination for 12 weeks does not reduce the incidence of developing a common cold when compared with placebo. However, symptom severity was modestly reduced. Also, each episode was reduced by an average of 1.1 days (107557). A more recent clinical study in adults at increased risk of developing a common cold shows that taking the same combination does not reduce symptom severity or the absolute number of common cold episodes when compared with placebo. However, in individuals with at least one cold, the mean number of colds was reduced by 0.12 over the 12-week period. In addition, there were modest overall reductions in the incidence of recurring colds and the use of analgesics (107555). A smaller clinical trial using the same product at the same dose and duration has also been conducted in children aged 1-6 years in daycare. The severity of nasal congestion/runny nose was modestly reduced when compared with placebo in this population. However, there were no differences between groups in the overall incidence, severity, or duration of common colds or upper respiratory tract infections or the number of days absent from daycare (107556). This latter trial was terminated prior to the completion of the planned patient recruitment for reasons unrelated to adverse effects, which may have impacted the findings. L. paracasei has also been investigated as part of fermented milk. A clinical trial in elderly nursing home residents shows that drinking two bottles of fermented milk containing L. paracasei Shirota daily for 6 months does not reduce the risk of developing respiratory symptoms when compared with placebo milk (96885). However, a small clinical study in healthy, male, middle-aged office workers shows that drinking a fermented milk made with L. paracasei Shirota for 12 weeks reduces the incidence and duration of the common cold by 59% when compared with a control milk (98426). Also, a clinical study in children aged 3-6 years attending daycare shows that drinking a fermented milk product containing L. paracasei (Actimel, Danone) 200 grams daily for 3 months reduces the risk of developing the common cold, the most common upper respiratory tract infection in these children, by around 18% when compared with a control milk product. The fermented milk product did not affect medication use or sick leave from daycare (96882).

POSSIBLY INEFFECTIVE

• Constipation. Oral Lacticaseibacillus paracasei does not seem to be beneficial for constipation. Details: Meta-analyses of two or three clinical trials in adults with functional constipation show that taking L. paracasei Shirota 6.5-30 billion colony-forming units daily for 4 weeks does not appear to improve gut transit time or increase the number of stools (95342). Also, clinical research in patients with constipation shows that taking a combination of L. paracasei Lpc-37 2.5 billion colony-forming units daily for 2 weeks along with Lactobacillus acidophilus NCFM and Bifidobacterium animalis subsp. lactis strains Bl-04, Bi-07, and HN019, does not improve bloating, abdominal pain, intestinal transit time, frequency of bowel movements, or stool consistency when compared with placebo. There was a small beneficial effect on flatulence (110979).

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Acne. It is unclear if topical heat-killed Lacticaseibacillus paracasei is beneficial for acne. Details: Preliminary clinical research in patients with mild to moderate acne shows that topical application with a lotion providing the cell-free supernatant of L. paracasei MSMC 39-1 twice daily for 4 weeks is as effective as a lotion containing 2.5% benzoyl peroxide for decreasing redness and the inflammatory acne lesion count. There was no effect of either lotion of non-inflammatory acne lesion count (111945). This study is limited by the lack of blinding to lotion type.
• Alcohol-related liver disease. It is unclear if oral Lacticaseibacillus paracasei is beneficial in patients with alcohol-related liver disease. Details: Clinical research in patients with alcohol-related liver disease shows that taking fermented milk providing L. paracasei Shirota daily for 60 days reduces levels of triglycerides and low-density lipoprotein (LDL) cholesterol by 27% and 24%, respectively, compared with taking placebo. There was also an improvement in liver function, based on modest improvements in various liver markers, including alanine aminotransferase, aspartate aminotransferase, gamma-glutamyltransferase, and bilirubin. Patients consumed L. paracasei 20 billion colony-forming units daily (111958).
• Antibiotic-associated diarrhea. It is unclear if oral Lacticaseibacillus paracasei is beneficial for preventing antibiotic-induced diarrhea. Details: Most clinical research has investigated the effect of L. paracasei in combination with other probiotics. A meta-analysis of 3 clinical trials in hospitalized or outpatient adults shows that taking L. paracasei in combination with up to 8 other probiotic strains reduces the risk of AAD by 40% when compared with taking placebo (107635). One of these studies, a small clinical trial in patients taking amoxicillin 500 mg twice daily for 7 days, used a specific combination probiotic (Ecologic AAD) twice daily for 14 days. The product provided L. paracasei NIZO 3672, Bifidobacterium bifidum NIZO 3804, Bifidobacterium animalis subsp. lactis NIZO 3680, Enterococcus faecium NIZO 3886, Lactobacillus acidophilus NIZO 3678 and NIZO 3887, Lactiplantibacillus plantarum NIZO 3684, Lacticaseibacillus rhamnosus NIZO 3689, and Ligilactobacillus salivarius NIZO 3675 as 1 billion colony-forming units (CFUs) each daily (95405). In addition, one small clinical study in hospitalized adults shows that consuming a 97 mL drink (Actimel, Danone) containing L. paracasei 100 CFUs/mL, Streptococcus thermophilus 100 million CFUs/mL, and Lactobacillus delbrueckii subsp. bulgaricus 10 million CFUs/mL twice daily while taking antibiotics reduces the odds of developing AAD by 75% when compared with a milkshake without probiotics (16740). However, an additional large clinical trial in children aged 3 months and up shows that taking L. paracasei in combination with other probiotics does not reduce the risk of antibiotic-associated diarrhea when compared with taking placebo, when the more stringent definition is considered excluding diarrhea of other etiologies. However, the risk of diarrhea of any etiology is reduced by 35%. The probiotic supplement provided a total of 10 billion CFUs of L. paracasei W20, Lactobacillus acidophilus W37, Lactobacillus acidophilus W55, Bifidobacterium bifidum W23, Bifidobacterium animalis subsp. lactis W51, Lactiplantibacillus plantarum W62, Lacticaseibacillus rhamnosus W71, and Ligilactobacillus salivarius W24 daily from the first day of antibiotic treatment until 7 days after treatment ended (110969). It is unclear if any benefits are due to L. paracasei, the other ingredients, or their combination. L. paracasei has also been investigated alone. In hospitalized patients with spinal cord injury, preliminary clinical research shows that 17.1% of patients taking L. paracasei Shirota 6.5 billion CFUs daily in a probiotic drink (Yakult light) developed diarrhea compared with 54.9% of those given only routine care. L. paracasei was taken during antibiotic treatment and for an additional 7 days (111955). This study is limited by a lack of blinding.
• Antituberculosis treatment-associated adverse effects. It is unclear if oral Lacticaseibacillus paracasei is beneficial for preventing adverse effects associated with antituberculosis treatment. Details: Preliminary clinical research shows that taking L. paracasei Shirota 10 billion or 20 billion colony-forming units (CFUs) daily during standard antituberculosis treatment does not reduce the incidence of liver injury when compared with antituberculosis treatment alone. However, there was a modest decrease in the incidence of elevated alkaline phosphatase in patients taking 20 billion CFUs daily and a modest decrease in the incidence of elevated bilirubin in patients taking 10 billion CFUs daily. There was no effect on other liver markers (107509). Other preliminary clinical research shows that taking this same dose daily for 2 months during standard antituberculosis treatment reduces the rate of any gastrointestinal adverse event to 29% to 38% of patients, compared with 50% of those taking antituberculosis treatment alone. In addition, the duration of symptoms was shorter. However, when individual gastrointestinal adverse events were evaluated, only the incidence and duration of vomiting and appetite loss were reduced; the incidence of nausea, diarrhea, flatulence, and constipation were unaffected (107542).
• Asthenopia (eye strain). It is unclear if oral heat-killed Lacticaseibacillus paracasei is beneficial for asthenopia. Details: Preliminary clinical research shows that taking heat-killed L. paracasei 50 mg daily for 8 weeks does not decrease eye fatigue induced by blue-light emitting devices when compared with placebo. However, a subgroup analysis shows that in patients who report eye fatigue at baseline, subjective symptoms of eye fatigue and eye redness are reduced after exposure to blue-light emitting devices (98429).
• Asthma. It is unclear if oral Lacticaseibacillus paracasei is beneficial for asthma. Details: A small clinical study in children with asthma shows that taking L. paracasei GMNL-133 (LP) 2 billion colony-forming units (CFUs), Limosilactobacillus fermentum GM-090 (LF) 2 billion CFUs, or both strains together daily for 3 months seems to modestly reduce asthma severity and increase Childhood Asthma Control Test (C-ACT) scores when compared with placebo (99785). In children ages 2-5 years with asthma, clinical research shows that taking fermented milk (Danone) containing L. paracasei DN-114 011 10 billion colony-forming units daily does not increase the time free from asthma episodes, the mean duration of episodes, or the cumulative number of episodes, when compared with taking a control milk. The fermented milk was made with the yogurt cultures Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus (112512).
• Cancer. Although there has been interest in using oral Lacticaseibacillus paracasei for cancer prevention or treatment, there is insufficient reliable information about the clinical effects of L. paracasei for this condition.
• Canker sores. Oral Lacticaseibacillus paracasei has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical trial shows that taking a combination of L. paracasei, Lacticaseibacillus rhamnosus, Lactobacillus acidophilus, and Bifidobacterium animalis subsp. lactis modestly reduces pain, but not the number of lesions or healing time, when compared with placebo (107548).
• Clostridioides difficile infection. Although there has been interest in using oral Lacticaseibacillus paracasei for C. difficile infection prevention, there is insufficient reliable information about the clinical effects of L. paracasei for this condition.
• Colic. Although there has been interest in using oral Lacticaseibacillus paracasei for colic, there is insufficient reliable information about the clinical effects of L. paracasei for this condition.
• Colorectal cancer. It is unclear if oral Lacticaseibacillus paracasei is beneficial for colorectal cancer prevention. Details: Clinical research in patients with previous removal of colorectal tumors shows that taking at least 1.5 billion colony-forming units L. paracasei Shirota 3 times daily for 4 years does not prevent the development of new colorectal tumors when compared with not taking L. paracasei. However, taking L. paracasei reduces the occurrence of colorectal tumors with moderate or severe atypia by 35%. Half of the patients included in this research were also consuming wheat bran biscuits (111959).
• Dental caries. It is unclear if oral Lacticaseibacillus paracasei is beneficial for dental caries prevention. Details: Preliminary clinical research shows that giving infants a weaning cereal containing L. paracasei F19 (Semper AB) from 4 months of age until 13 months of age does not reduce the risk of dental caries in the primary or permanent teeth by the age of 3, 6, or 9 years (90260).
• Depression. Although there has been interest in using oral Lacticaseibacillus paracasei for depression, there is insufficient reliable information about the clinical effects of L. paracasei for this condition.
• Diabetes. Oral Lacticaseibacillus paracasei has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in patients with gestational diabetes shows that taking a specific product containing L. paracasei and other probiotics (Visbiome, ExeGi Pharma) as a total of 112.5 billion colony-forming units (CFUs) twice daily for 8 weeks does not affect levels of fasting blood glucose or glycated hemoglobin (HbA1c) when compared with placebo. However, there were small improvements in insulin levels and insulin resistance (107549). This same combination probiotic has also been evaluated in children 2-12 years of age with new-onset type 1 diabetes. One clinical study shows that taking Visbiome as 112.5 billion CFUs daily for 3 months modestly decreases HbA1c and insulin requirements when compared with placebo. Also, about three times as many children achieved remission, defined as insulin requirements of less than 0.5 U/kg daily and HbA1c of less than 7%. However, C-peptide levels and the maintenance of residual pancreatic beta-cell function were not affected when compared with placebo (107497).
• Diarrhea. It is unclear if oral Lacticaseibacillus paracasei is beneficial for the treatment of diarrhea. Details: While the European Society for Pediatric Infectious Diseases recommends probiotics in hospitalized children with diarrhea (98469) and the Infectious Disease Society of America (IDSA) recommends probiotics for the outpatient treatment of acute diarrhea (95388), both guidelines note that most evidence is low quality. Also, evidence related to the use of L. paracasei, specifically, is limited. One large clinical study shows that taking a fermented milk product containing L. paracasei DN-114 001 (e.g., DanActive, Dannon) 100 million CFUs per milliliter for up to 4 months helps to prevent acute, non-rotaviral diarrhea in children ages 6-24 months (14374).
• Exercise-induced muscle damage. It is unclear if oral Lacticaseibacillus paracasei is beneficial for exercise-induced muscle damage. Details: Clinical research in adults shows that taking L. paracasei L-PS23 20 billion colony-forming units or heat-killed L. paracasei HK-PS23 20 billion cells daily modestly reduces muscle strength loss and improves measures of muscle recovery in the 48 hours following exercise-induced muscle damage when compared with taking placebo. L. paracasei was taken for 6 weeks prior to inducing muscle damage and continued for an additional 48 hours (111940).
• Exercise-induced respiratory infections. It is unclear if oral Lacticaseibacillus paracasei is beneficial for preventing respiratory infections related to exercise. Details: Clinical research in endurance athletes shows that taking a probiotic supplement containing L. paracasei Shirota (LCS, Yakult) 65 billion colon-forming units (CFUs) twice daily for 20 weeks does not reduce the risk of developing an upper respiratory tract infection when compared with placebo. Taking this probiotic also does not reduce the duration or severity of respiratory infections in this population (98431). However, other clinical research shows that taking L. paracasei Shirota 6.5 billion CFUs daily for 4 months during winter endurance training modestly reduces the proportion of athletes with at least 1 week with upper respiratory tract illness symptoms by 27%, and the total number of episodes by 0.9, when compared with taking placebo. There was no difference in symptom severity or duration (111950).
• Fractures. It is unclear if oral Lacticaseibacillus paracasei is beneficial for the healing of fractures. Details: A clinical study in elderly adults with distal radius fracture shows that consuming 100 mL of skim milk containing L. paracasei Shirota 12 billion colony-forming units twice daily for 3 months modestly improves hand function, pain, and daily life activities when compared with skimmed milk placebo (102407). This study is limited by the fact that, although subjective measures showed improvement, there was no consistent improvement in objective measures.
• Helicobacter pylori. It is unclear if oral Lacticaseibacillus paracasei is beneficial in children with H. pylori infection. Details: Clinical research in H. pylori-colonized children aged 6 to 17 years shows that taking a fermented dairy product containing live or heat-killed L. paracasei ST11 (Chamyto, Nestle'-Chile SA, Santiago, Chile) 1.6 billion cells or colony-forming units 5 days each week for 4 weeks does not reduce H. pylori colonization when compared with the beverage without L. paracasei. The beverages were fermented with Lactobacillus helveticus (110934).
• HIV/AIDS. Although there has been interest in using oral Lacticaseibacillus paracasei for HIV/AIDS, there is insufficient reliable information about the clinical effects of L. paracasei for this condition.
• Hypercholesterolemia. It is unclear if oral Lacticaseibacillus paracasei is beneficial for hypercholesterolemia. Details: A small clinical trial in patients with hypercholesterolemia shows that taking 10.5 billion colony-forming units of L. paracasei TISTR 2593 daily for 90 days reduces levels of low-density lipoprotein cholesterol by about 11% when compared with taking placebo. There was no effect on total or high-density lipoprotein cholesterol or triglyceride levels (111938).
• Insomnia. It is unclear if oral Lacticaseibacillus paracasei is beneficial for improving sleep quality. Details: A small clinical trial in students shows that taking fermented milk containing L. paracasei Shirota daily for 11 weeks, starting 8 weeks prior to a stressful standardized examination, modestly reduces feelings of sleepiness upon rising and increases sleep length when compared with a non-fermented placebo milk. Objective measures of sleep latency were also reduced. There was no effect on total sleep time or sleep efficacy (111949).
• Irritable bowel syndrome (IBS). It is unclear if oral Lacticaseibacillus paracasei is beneficial for IBS. Details: One clinical study shows that taking a specific multi-species probiotic (Visbiome, ExeGi Pharma) containing L. paracasei and seven other probiotics as 450 billion colony-forming units (CFUs) daily in two divided doses for 8 weeks improves abdominal bloating, but not abdominal pain, flatulence, or number of stools, in patients with diarrhea-predominant IBS (IBS-D) (11379). However, adding this product as 900 billion CFUs daily to a sham diet or a low-FODMAP diet for 4 weeks does not improve IBS symptoms when compared with placebo (98741). Another clinical study in patients with IBS-D shows that taking a specific multi-species probiotic (NordBiotic, MBM Biotix) containing L. paracasei LPC100, Lacticaseibacillus rhamnosus LR110, Lactobacillus acidophilus LA120, Lacticaseibacillus casei LC130, and Lactiplantibacillus plantarum LP140, Bifidobacterium breve BB010, Bifidobacterium longum BL020, Bifidobacterium bifidum BF030, Bifidobacterium animalis subsp. lactis BL040, and Streptococcus thermophilus ST250 as 2.5 billion CFUs total twice daily for 8 weeks improves overall symptom severity, as well as pain severity, pain frequency, and quality of life when compared with placebo. Symptom severity was rated as mild by approximately 60% of those taking the probiotic mixture, compared with 30% of those taking placebo (107516). However, other clinical research shows that taking L. paracasei HA-196 10 billion CFUs daily or L. paracasei Shirota 13 billion CFUs daily for 8 weeks or a combination of L. paracasei, L. acidophilus, and B. animalis subsp. lactis BB-12 (Cultura) 13-20 billion CFUs daily for 6 months does not improve most symptoms of IBS (90236,94696,94697,103440,111952). L. paracasei has also been examined in combination with other ingredients. In patients 60 years and older with IBS, taking L. paracasei DKGF1 100 billion CFUs daily with Opuntia humifusa extract more than doubles the proportion of patients with improvements in self-reported overall symptoms during more than 2 of the 4 weeks of treatment when compared with taking placebo. Response rates for abdominal pain and psychological well-being were also improved. However, there were no differences between groups for response rates related to improvements in gas or bloating (111943).
• Japanese cedar pollinosis. It is unclear if oral Lacticaseibacillus paracasei is beneficial for Japanese cedar pollinosis. Details: Clinical research in patients with Japanese cedar pollinosis shows that taking L. paracasei KW3110 at least one trillion colony-forming units daily for 12 weeks starting 1 month before the start of the pollen season does not improve nasal symptoms during peak season when compared with taking placebo (111948).
• Lower respiratory tract infections. Oral Lacticaseibacillus paracasei has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in children ages 3-6 years shows that taking taking fermented milk (DanActive, Dannon) containing L. paracasei DN-114 011 20 billion colony-forming units daily for 90 days does not prevent lower respiratory tract infections when compared with taking a control non-fermented milk. The fermented milk was made with the yogurt cultures Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus (112515).
• Lyme disease. Although there has been interest in using oral Lacticaseibacillus paracasei for Lyme disease, there is insufficient reliable information about the clinical effects of L. paracasei for this condition.
• Migraine headache. It is unclear if oral Lacticaseibacillus paracasei is beneficial for migraine treatment. Details: Clinical research in patients with moderate to severe vestibular symptoms associated with migraine headaches shows that taking L. paracasei Shirota 20 billion colony-forming units daily for 4 months modestly reduces symptoms of vertigo and dizziness. The number of attacks with vertigo each week was reduced by 1.6, compared with 0.9 in patients taking placebo. Both vertigo and dizziness severity, as well as feelings of anxiety and depression, were also modestly reduced (111951). Although changes in these endpoints were statistically significant after 4 months, there were no differences between endpoints after 2 months, and the clinical significance is unclear.
• Necrotizing enterocolitis (NEC). It is unclear if oral Lacticaseibacillus paracasei is beneficial or safe for NEC prevention. Details: Most meta-analyses of clinical research show that giving lactobacilli enterally reduces the risk of NEC and/or severe NEC in preterm, mainly very low birth weight (VLBW), infants. Some meta-analyses support the use of lactobacilli in combination with bifidobacteria, as opposed to lactobacilli alone for reducing the risk of NEC. However, the effects of L. paracasei, specifically, are unclear (95344,95351,103437,103445,104157,105162,105164). Also, guidance among regulatory agencies and clinical organizations varies with respect to the use of probiotics in very low birth weight infants under 1000 grams. The US Food and Drug Administration (FDA) warns that preterm infants given probiotics are at risk of serious infections caused by the bacteria or fungi contained in probiotics due to cases reported in this group of infants (111610). Also, The American Academy of Pediatrics does not support the routine administration of probiotics to preterm infants, particularly those with a birth weight below 1000 grams, due to conflicting data on safety and efficacy and potential for harm in this vulnerable population (111608). The Canadian Paediatric Society, the American Gastroenterological Association, and the European Society for Paediatric Gastroenterology, Hepatology and Nutrition state that probiotic combinations may be of benefit in reducing the incidence of NEC in preterm neonates over 1000 grams. However, L. paracasei is not specifically recommended (103003,111609,111611).
• Nonalcoholic fatty liver disease (NAFLD). Oral Lacticaseibacillus paracasei has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in patients with NAFLD shows that taking 2 sachets daily for 3 months of a specific combination product (VSL#3) containing L. paracasei and other probiotics modestly decreases triglyceride levels and liver enzymes when compared with taking placebo. However, there was no change in body mass index or most glycemic or lipid parameters (111009). The effect of L. paracasei alone is unclear from this study.
• Osteoarthritis. It is unclear if oral Lacticaseibacillus paracasei is beneficial for osteoarthritis. Details: A large clinical trial in patients with mild to moderate symptoms of knee osteoarthritis shows that taking skim milk containing L. paracasei Shirota 6 billion colony-forming units twice daily for 6 months modestly improves stiffness, pain, and function when compared with taking skim milk placebo (111953). More research is needed to determine whether L. paracasei Shirota is as effective as standard medications.
• Pain (acute). It is unclear if oral Lacticaseibacillus paracasei is beneficial for acute pain. Details: Clinical research in patients with a single rib fracture shows that taking skim milk containing L. paracasei Shirota 6 billion colony-forming units daily for 1 month modestly reduces pain during deep breathing, coughing, and turning over when compared with taking skim milk placebo. Good pain relief during these situations, defined as a decline in maximal pain intensity of 3 points on a 10-point scale, occurred in 42.1% to 61.6% of patients, compared with 25.9% to 47.3% of patients taking placebo. However, there was no effect on sleep quality (111957).
• Parkinson disease. It is unclear if oral Lacticaseibacillus paracasei is beneficial for Parkinson disease. Details: Clinical research in patients with Parkinson disease shows that taking fermented milk providing L. paracasei Shirota 10 billion colony-forming units daily for 12 weeks reduces the use of laxatives by 0.37 or 15% per week and modestly improves stool consistency and symptoms of constipation when compared with taking an acidified milk placebo. There were also modest improvements in non-motor symptoms, anxiety, and depression, but not overall disease severity or dopaminergic therapy requirement (111956).
• Postoperative infection. Although there has been interest in using oral Lacticaseibacillus paracasei for preventing postoperative infections, there is insufficient reliable information about the clinical effects of L. paracasei for this purpose.
• Pouchitis. Oral Lacticaseibacillus paracasei has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research shows that continuous oral treatment for one year with a specific combination product (Visbiome, ExeGi Pharma) containing L. paracasei and other probiotics, 6 grams (300-500 billion live bacteria per gram) daily, for up to 12 months seems to maintain remission in 85% of patients with pouchitis (6087,12769).
• Pregnancy-induced nausea and vomiting. Oral Lacticaseibacillus paracasei has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small preliminary clinical trial shows that taking probiotics during pregnancy reduces the severity and duration of nausea and vomiting by 16% to 54%. There was also a small benefit on stool hardness. A specific probiotic (Probiotics 10, Nature's Bounty) was taken as 2 capsules daily for two back-to-back cycles of six days with probiotics and two days without. Each capsule contained a total of 10 billion colony-forming units (CFUs) of L. paracasei DSM 13434 and Lpc-37, Lactiplantibacillus plantarum 299v and DSM 15312, Lactobacillus delbrueckii subsp. bulgaricus Lb-87, Ligilactobacillus salivarius Ls-33, Levilactobacillus brevis Lbr-35, Lactobacillus acidophilus La-14, Lacticaseibacillus casei Lc-11, and Bifidobacterium animalis subsp. lactis Bl-04, along with inulin 200 mg (107199).
• Prostatitis. It is unclear if oral Lacticaseibacillus paracasei is beneficial for prostatitis. Details: Preliminary clinical research in adults with chronic bacterial prostatitis who are receiving antibiotic treatment shows that taking L. paracasei CNCM I-1572 (L. casei DG) one capsule twice daily for 6 months improves clinical symptoms over baseline in 73% of patients and also reduces symptomatic recurrence and antibiotic use (105133). The validity of these findings is limited by the lack of a comparator group.
• Proton pump inhibitor-induced gastrointestinal (GI) symptoms. It is unclear if oral Lacticaseibacillus paracasei is beneficial for preventing GI symptoms in patients using proton pump inhibitors. Details: Preliminary clinical research in patients with gastroesophageal reflux disease shows that taking L. paracasei F19 (Genefilus F19, Siffra Farmaceutici S.r.l., Italy) 24 billion colony-forming units 3 times a week for 3 or 6 months during treatment with pantoprazole 40 mg daily modestly reduces stool frequency and the severity and proportion of patients with flatulence and bloating when compared with taking placebo (111941).
• Radiation-induced diarrhea. Oral Lacticaseibacillus paracasei has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical trial in patients undergoing pelvic radiotherapy shows that taking 96 mL fermented milk (Danone) 3 times daily containing L. paracasei DN-114 001 100 million colony-forming units per gram starting one week before the initiation of radiation treatment does not delay the development of diarrhea when compared with taking a control sterilized milk product. The fermented milk was continued throughout treatment and made with the yogurt cultures Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus (112513).
• Rotaviral diarrhea. It is unclear if oral Lacticaseibacillus paracasei is beneficial for rotaviral diarrhea. Details: The current guidelines related to the treatment of viral diarrhea are conflicting. While the World Gastroenterology Organization has not made a recommendation (98471), the European Society for Pediatric Infectious Diseases recommends probiotics in hospitalized children with diarrhea (98469) and the Infectious Disease Society of America (IDSA) recommends probiotics for the outpatient treatment of acute diarrhea (95388). However, these guidelines note that most evidence is low quality and is not specific to rotavirus infection. Furthermore, these guidelines were released prior to the publication of the most recent, high-quality studies showing no benefit with the use of certain probiotics (98427,98428). Also, research on the use of L. paracasei, specifically, is lacking.
• Sarcopenia. Although there has been interest in using oral Lacticaseibacillus paracasei for sarcopenia prevention, there is insufficient reliable information about the clinical effects of L. paracasei for this purpose.
• Short bowel syndrome. Although there has been interest in using oral Lacticaseibacillus paracasei for short bowel syndrome, there is insufficient reliable information about the clinical effects of L. paracasei for this condition.
• Small intestinal bacterial overgrowth (SIBO). It is unclear if oral Lacticaseibacillus paracasei is beneficial for the treatment of SIBO. Details: One preliminary clinical study in adults with irritable bowel syndrome and a recent diagnosis of SIBO shows that consuming 65 mL of a specific product (Yakult, Yakult Ltd.) providing 6.5 billion colony-forming units (CFUs) of L. paracasei Shirota by mouth daily for 6 weeks modestly improves flatulence, but not other symptoms, when compared to baseline (91144).
• Ulcerative colitis. Oral Lacticaseibacillus paracasei has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: The best evidence of benefit is for a specific combination product (Visbiome, ExeGi Pharma). Doses of 3 grams (equivalent to 900 billion colony-forming units (CFUs)) once or twice daily have been used in combination with conventional treatment. In children aged 1-16 years, doses of 450-1800 billion CFUs for up to one year have been used (3261,14370,14371,16841,95337). A meta-analysis of clinical research shows that taking this product as an adjunct to standard ulcerative colitis treatment can increase remissions rates in adults and children by about 1.7-fold when compared with standard treatment alone (95337). There is also evidence that it is beneficial for improving remission rates in patients who do not adequately respond to conventional treatment (14371).
• Upper respiratory tract infection (URTI). Oral Lacticaseibacillus paracasei has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in children ages 3-6 years shows that taking taking fermented milk (DanActive, Dannon) containing L. paracasei DN-114 011 20 billion colony-forming units daily for 90 days reduces the incidence of URTIs by 18% when compared with taking a control non-fermented milk. The fermented milk was made with the yogurt cultures Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus (112515).
• Wound healing. It is unclear if oral Lacticaseibacillus paracasei is beneficial for the treatment of SIBO. Details: Clinical research in patients with a recent episiotomy shows that taking L. paracasei (L. casei 431) 1.5 billion colony-forming units daily for 14 days modestly improves wound severity, including redness, swelling, and discharge, 5 and 15 days after birth when compared with taking placebo. There was no effect on wound pain (112519). More evidence is needed to rate Lacticaseibacillus paracasei for these uses.

POSSIBLY EFFECTIVE

• Antibiotic-associated diarrhea. Most research shows that oral Lactobacillus acidophilus, alone or in combination with other probiotics, seems to reduce the risk of antibiotic-associated diarrhea (AAD) in adults. Details: A meta-analysis of 18 clinical trials in hospitalized or outpatient adults shows that taking L. acidophilus alone or in combination with up to 8 other probiotic strains reduces the risk of AAD by 34% when compared with taking placebo (107635). One small clinical trial in elderly adults shows that AAD occurred in 17% of those taking L. acidophilus (Florajen Acidophilus) 20 billion colony-forming units (CFUs) three times daily, compared with 37% of those taking placebo (95400). A number of combination products have also demonstrated benefit for preventing AAD, including Bio-K+ Cl1285 which provides L. acidophilus CL1285, Lacticaseibacillus casei LBC80R, and Lacticaseibacillus rhamnosus CLR2 as 100 billion CFUs daily (25494,95402,95403); L. acidophilus and Bifidobacterium animalis subsp. lactis (90239); and Ecologic AAD which provides L. acidophilus NIZO 3678 and NIZO 3887, Lacticaseibacillus paracasei NIZO 3672, Lactiplantibacillus plantarum NIZO 3684, L. rhamnosus NIZO 3689, Ligilactobacillus salivarius NIZO 3675, Bifidobacterium bifidum NIZO 3804, Bifidobacterium animalis subsp. lactis NIZO 3680, and Enterococcus faecium NIZO 3886 (95405). However, some combination products have not demonstrated benefit. Clinical research shows that taking a combination of L. acidophilus and bifidobacteria or a combination of L. acidophilus and Lactobacillus delbrueckii subsp. bulgaricus (Lactinex) is not beneficial (90231,90239,92255,95385). An additional large clinical trial in children aged 3 months and up shows that taking L. acidophilus in combination with other probiotics does not reduce the risk of antibiotic-associated diarrhea when compared with taking placebo, when the more stringent definition is considered excluding diarrhea of other etiologies. However, the risk of diarrhea of any etiology is reduced by 35%. The probiotic supplement provided a total of 10 billion CFUs of L. acidophilus W37, Bifidobacterium bifidum W23, Bifidobacterium animalis subsp. lactis W51, Lactobacillus acidophilus W55, Lacticaseibacillus paracasei W20, Lactiplantibacillus plantarum W62, Lacticaseibacillus rhamnosus W71, and Ligilactobacillus salivarius W24 daily from the first day of antibiotic treatment until 7 days after treatment ended (110969).
• Bacterial vaginosis. Most clinical research shows that intravaginal application of Lactobacillus acidophilus may be helpful for the treatment of bacterial vaginosis. It is unclear if oral L. acidophilus is beneficial for the treatment or prevention of bacterial vaginosis. Details: One clinical trial shows that intravaginal suppositories containing 100 million to 1 billion colony-forming units (CFUs) of L. acidophilus (Vivag, Pharma Vinci A/S) given twice daily for 6 days improve bacterial vaginosis resolution rates when compared with placebo (13177). Another clinical trial shows that using 1-2 vaginal tablets containing viable L. acidophilus 10 million CFUs and estriol 0.03 mg per tablet (Gynoflor, Medinova) daily for 6 days increases cure rates when compared with placebo (13176). However, using this product in combination with metronidazole 400 mg twice daily for 7 days does not improve outcomes when compared with metronidazole alone (90237). Preliminary clinical research in patients with clinically defined bacterial vaginosis shows that daily intravaginal application with a douche providing L. acidophilus 1 billion CFUs per mL for 6 days might have beneficial effects on the vaginal flora. When compared with 52.5% of patients with bacterial vaginosis based on bacterial flora at baseline, 7.5% met this criteria 14 days after treatment had been completed (111788). Oral L. acidophilus has also been evaluated. Preliminary clinical research shows that eating yogurt 125 mL daily enriched with L. acidophilus for 2 months might slightly decrease the incidence of recurrent bacterial vaginosis (1245). L. acidophilus has also been investigated in an oral formulation in combination with other probiotics. Clinical research in patients with bacterial vaginosis cured within the past 48 hours shows that taking a product containing L. acidophilus in combination with other probiotics results in recurrence of vaginosis in 18.3% of patients, a statistically significant reduction compared with 32.1% of those using placebo. The mean time to recurrence was approximately 23 days longer in patients taking the lactobacilli. The product contained L. acidophilus 1.08 billion CFUs along with Lactobacillus crispatus LMG S-29995 and Levilactobacillus brevis (Lactogyn, Vésale Pharma, Belgium), and was taken twice daily for 7 days and then once daily for up to an additional 120 days (110950).
• Helicobacter pylori. Oral Lactobacillus acidophilus, usually in combination with other probiotics, seems to improve H. pylori eradication when used along with standard therapies. It is unclear if heat-killed L. acidophilus is beneficial for H. pylori eradication. Details: A meta-analysis of clinical studies utilizing probiotic products containing L. acidophilus shows that these products can improve H. pylori eradication rates 1.14- to 1.24-fold when taken in combination with triple therapy consisting of a proton-pump inhibitor (PPI), clarithromycin, and amoxicillin. Based on these results, about 7-11 patients would need to be treated in order for one additional patient to achieve complete remission (95394). Only one of the trials in this analysis investigated L. acidophilus alone; an additional 8 used L. acidophilus in combination with other probiotics. Individual clinical trials have shown that a combination of L. acidophilus, Enterococcus faecalis, and Bacillus subtilis 30 million colony-forming units (CFUs) total, taken in three divided doses daily, from 2 weeks prior tol 2 weeks after triple therapy increases H. pylori eradication when compared with triple therapy alone (90248). In children, a combination of L. acidophilus (strain 5) 94 million CFUs and Bifidobacterium bifidum (strain 12) 8.6 million CFUs in combination with a PPI, clarithromycin, and amoxicillin or metronidazole has been used daily for 2 weeks, followed by the probiotics alone for an additional 4 weeks (90602). However, other individual clinical trials have shown that L. acidophilus in combination with Lacticaseibacillus rhamnosus, Bifidobacterium bifidum, and Streptococcus faecium may not improve eradication rates when taken with triple therapy consisting of furazolidone, tetracycline, and lansoprazole (90279). Also, taking L. acidophilus along with six other probiotics in conjunction with bismuth quadruple therapy does not seem to improve H. pylori eradication rates when compared with placebo and bismuth quadruple therapy (90291). Also, taking L. acidophilus and L. casei without any standard H. pylori therapy does not improve H. pylori eradication rates in adults (12766). Heat-killed L. acidophilus has also been investigated in adults with H. pylori. Taking a lyophilized and inactivated culture of L. acidophilus (Lacteol Fort) containing 5 billion cells, 3 times daily for 10 days, modestly increases the eradication rate in patients using triple therapy of rabeprazole, clarithromycin, and amoxicillin for 7 days (8562).
• Irritable bowel syndrome (IBS). Some research shows that oral live Lactobacillus acidophilus, taken alone or in combination with other probiotics, may be beneficial for IBS. The effects of non-viable, heat-killed L. acidophilus are unclear. Details: Clinical research in adults with IBS shows that taking L. acidophilus DDS-1 10 billion colony-forming units (CFUs) daily for 6 weeks modestly reduces the severity of abdominal pain when compared with placebo. Also, 52% of patients experienced a more than 30% reduction in pain severity, compared with 16% of those taking placebo. There were also improvements in abdominal distention and duration of pain; however, there were no changes in bowel habits (107581). A meta-analysis shows that taking L. acidophilus improves the rate of symptom relief and reduces bloating severity when compared with placebo. However, other symptoms were not improved (110866). L. acidophilus has also been examined in combination with other probiotics. One clinical study shows that taking a specific combination product (Visbiome, ExeGi Pharma) containing L. acidophilus and 7 other species as 450 billion CFUs daily in two divided doses for 8 weeks improves abdominal bloating, but not abdominal pain, flatulence, or number of stools, in patients with diarrhea-predominant IBS (IBS-D) (11379). Another clinical study in patients with IBS-D shows that taking a specific multi-species probiotic (NordBiotic, MBM Biotix) containing L. acidophilus LA120, Lacticaseibacillus rhamnosus LR110, Lacticaseibacillus paracasei LPC100, Lacticaseibacillus casei LC130, Lactiplantibacillus plantarum LP140, Bifidobacterium breve BB010, Bifidobacterium longum BL020, Bifidobacterium bifidum BF030, Bifidobacterium animalis subsp. lactis BL040, and Streptococcus thermophilus ST250 as 2.5 billion CFUs total twice daily for 8 weeks improves overall symptom severity, as well as pain severity, pain frequency, and quality of life, when compared with placebo. Symptom severity was rated as mild by approximately 60% of those taking the probiotic mixture, compared with 30% of those taking placebo (107516). A small clinical trial shows that taking L. acidophilus NCFM plus Lactobacillus helveticus Lafti L10 (Lallemand Health Solutions) 5 billion CFUs each daily for 8 weeks modestly reduces flatus and overall symptoms, but not abdominal pain or bloating, when compared with taking placebo (111785). However, other probiotic compounds containing L. acidophilus have not demonstrated benefit in most patients with IBS. These include L. acidophilus NCFM 10 billion CFUs daily for 12 weeks; L. acidophilus, L. paracasei, and Bifidobacterium animalis subsp. lactis BB-12 (Cultura) 13-20 billion CFUs daily for 6 months; or L. acidophilus CL1285, L. casei LBC80R, and L. rhamnosus CLR2 50 billion CFUs each daily for 3 months (90236,94696,94697,95365,99789). Further research is needed to determine which IBS subtype, if any, is most likely to benefit. Heat-killed L. acidophilus has also been investigated in patients with IBS. One clinical study shows that taking capsules containing heat-killed L. acidophilus (Lacteol Fort) 20 billion colony-forming units (CFUs) daily for 6 weeks improves abdominal pain, bloating, and number and quality of stools when compared with placebo (7744). Also, in patients with IBS-D, observational research has found that use of heat-killed L. acidophilus (Lacteol LB) two capsules daily for one month modestly reduces pain and bloating and improves quality of life. The average weekly number of stools decreased by approximately 4.75. Also, the number of patients with watery stools was reduced from 54% at baseline to 19% (107535).

POSSIBLY INEFFECTIVE

• Atopic disease. Oral Lactobacillus acidophilus does not seem to be beneficial for preventing atopic disease in children. Details: A meta-analysis of clinical research shows that administering L. acidophilus during pregnancy, when breastfeeding, or to newborn infants might actually increase the risk of atopic sensitization (90251). However, the number of studies included in this analysis was limited.

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Acne. Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A preliminary clinical study shows that taking a specific probiotic product containing L. acidophilus 5 billion colony-forming units (CFUs), Lactobacillus delbrueckii subsp. bulgaricus 5 billion CFUs, and Bifidobacterium bifidum 20 billion CFUs (Trenev Trio/Healthy Trinity, Natren) twice daily along with minocycline once every evening for 12 weeks improves inflamed and non-inflamed acne lesions in 82% of patients, compared to only 67% of patients treated with either the probiotic combination or minocycline alone (90270).
• Acute respiratory distress syndrome (ARDS). Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in premature infants shows that taking 6 billion CFUs of a combination of L. acidophilus NCDO 1748 and Bifidobacterium bifidum NCDO 2203 (UFC Inforan, Switzerland) from 7 days of age until 34 weeks postmenstrual age or discharge does not reduce the odds of ARDS when compared with a control group of infants not given these probiotics. The infants in this study were born at less than 32 weeks gestation and had a birthweight of less than 1500 grams (111794). This study is limited by the lack of randomization to treatment group; placement was based on year of birth.
• Allergic rhinitis (hay fever). It is unclear if oral Lactobacillus acidophilus is beneficial for allergic rhinitis prevention or treatment. Details: A small clinical trial in patients with perennial allergic rhinitis shows that taking heat-treated milk fermented with L. acidophilus L-92 100 mL daily for 8 weeks modestly reduces nasal symptoms and mucus, but not ocular symptoms, when compared with taking an acidified placebo milk. The milk provided approximately 30 billion L. acidophilus cells (25488). The effect of L. acidophilus as a probiotic is unclear from this study. Other clinical research shows that drinking 250 mL of fermented milk containing L. acidophilus La-5 5 billion colony-forming units (CFUs), Lacticaseibacillus rhamnosus GG 50 billion CFUs, and Bifidobacterium animalis subsp. lactis BB-12 50 billion CFUs from 36 weeks' gestation until 3 months postpartum does not reduce the incidence of allergic rhinitis in the child at 6 years of age when compared with placebo milk (96893).
• Asthma. It is unclear if oral Lactobacillus acidophilus can improve lung function in people with asthma. Details: A small clinical crossover study in patients with moderate asthma shows that consuming live active yogurt 225 grams, providing L. acidophilus 760 million colony-forming units (CFUs) per gram, twice daily for 1 month does not affect measures of lung function when compared with yogurt not containing L. acidophilus. All yogurt contained Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus (1244).
• Atopic dermatitis (eczema). Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A meta-analysis of the available clinical research shows that intake of lactobacilli and bifidobacteria-based probiotics during gestation, followed by giving the probiotic to the newborn for the first 2-6 months of life, reduces the risk of developing atopic dermatitis by 40% over the next 6-24 months when compared with placebo, regardless of family history of atopy. However, only four of 10 studies included in the analysis used L. acidophilus as part of the probiotic combination; the results from these individual, small studies support the overall findings of the meta-analysis (107503). Some clinical research also shows that supplementation with 250 mL of fermented milk containing L. acidophilus La-5, Lacticaseibacillus rhamnosus GG, and Bifidobacterium animalis subsp. lactis BB-12 starting at 36 weeks' gestation and continuing until 3 months' postpartum, without supplementation in the infant, reduces the overall occurrence of atopic dermatitis in the child at 2 years of age. However, at 6 years of age, the effect appears to be inconclusive (96893). In children ages 1-3 years with moderate to severe atopic dermatitis, taking 5 billion colony-forming units (CFUs) of a combination of L. acidophilus DDS-1 and Bifidobacterium animalis subsp. lactis UABLA-12 along with fructo-oligosaccharides (FOS) (DDS Junior) twice daily for 8 weeks modestly reduces symptom severity and the need for topical corticosteroids when compared with placebo (110995).
• Bronchopulmonary dysplasia. Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One large observational study in premature infants suggests that taking L. acidophilus 1 to 3 billion CFUs with Bifidobacterium longum subsp. infantis during the first month of life for the prevention of necrotizing enterocolitis was not associated with a reduced risk of bronchopulmonary dysplasia. The infants in this study were born between 22-29 weeks gestation and had a birthweight of less than 1500 grams (111771).
• Cancer. Although there has been interest in using oral Lactobacillus acidophilus for cancer prevention or treatment, there is insufficient reliable information about the clinical effects of L. acidophilus for this condition.
• Canker sores. Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A systematic review and meta-analysis of mainly small and preliminary clinical trials shows that taking lactobacilli probiotics has a small effect on pain from canker sores. However, the dose and duration of probiotic and the specific species, as well as endpoints and results from individual studies, are mixed. One small study shows that taking a combination of L. acidophilus, Lacticaseibacillus paracasei, Lacticaseibacillus rhamnosus, and Bifidobacterium animalis subsp. lactis reduces pain, but not the number of lesions or healing time, when compared with placebo. Another study shows that using lozenges providing inulin 0.13 gram along with L. acidophilus and B. animalis subsp. lactis 1.5 billion colony-forming units each reduces pain, but does not affect ulcer size or healing, when compared with Oracure gel (105146). Many of the individual studies may have been underpowered to detect a difference between groups.
• Cholestasis. Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in premature infants shows that the risk of developing cholestasis is reduced from 22% to 6% in those given a blend of L. acidophilus, bifidobacteria, and Enterococcus faecalis (Peifeikang powder, Shanghai Xinyi Pharmaceutical Company) at least 5 million colony-forming units three times daily, from birth until implementation of total parenteral nutrition, when compared with infants not given this powder. In the infants that developed cholestasis, the severity was reduced, resulting in a reduction in the rate of cholestatic liver injury, feeding intolerance, and necrotizing enterocolitis. The number of days to reach full enteral feeding, days to normal weight gain, and days of hospitalization were reduced by approximately 2.8, 2.1, and 1.7 days, respectively (103448).
• Clostridioides difficile infection. It is unclear if oral Lactobacillus acidophilus is beneficial for preventing C. difficile occurrence or recurrence. Details: Current guidelines from the Infectious Diseases Society of America (IDSA) state that there is insufficient information to recommend administration of probiotics for the primary prevention of C. difficile-associated diarrhea (107538). Evidence from clinical and observational research investigating the effect of L. acidophilus on C. difficile occurrence or recurrence is weak. Most studies use this species in combination with one or more additional probiotic species, including as Bio-K+ CI1285, containing L. acidophilus CL1285 and L. casei LBC80R, and as Bio-K+ 50 Billion, containing L. acidophilus CL1285, Lacticaseibacillus casei LBC80R, and Lacticaseibacillus rhamnosus CLR2 (25494,90231,90934,95369,95403,107529). Observational research has found that providing the Bio-K+ 50 Billion product as 50-100 billion colony-forming units (CFUs) daily for 5 days to patients who are on antibiotics for at least 2 days reduces the hospital-wide incidence of C. difficile by approximately 40%. The incidence rate was decreased by at least 50% in the highest risk individuals taking this combination (107529).
• Colic. Oral inactivated Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One clinical study in infants with colic shows that giving a specific multi-ingredient product (Colimil Plus, Milte Italia SPA) containing inactivated L. acidophilus 1 billion colony-forming units, lemon balm 65 mg, and German chamomile 9 mg twice daily for 4 weeks reduces crying time similarly to Limosilactobacillus reuteri DSM 17938 100 million CFUs daily (96278). It is unclear how L. acidophilus compares with no treatment.
• Common cold. Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in school children shows that taking a combination of L. acidophilus and Bifidobacterium bifidum (Infloran, Berna) 1 billion colony-forming units each twice daily for 3 months reduces the absolute percentage of school absence due to cold symptoms by 30% when compared with placebo (90286).
• Constipation. Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research shows that stool frequency is increased and symptoms of functional constipation in adults are improved with the use of a specific combination product (Hexbio) providing L. acidophilus, Lacticaseibacillus casei, Lactobacillus delbrueckii subsp. lactis, Bifidobacterium bifidum, Bifidobacterium longum, and Bifidobacterium longum subsp. infantis 30 billion colony-forming units (CFUs) twice daily for 7 days (90266). However, most other probiotic compounds containing L. acidophilus have not demonstrated benefit in most patients with constipation. One small clinical trial shows that taking yogurt 180 mL providing L. acidophilus NCFM, Bifidobacterium animalis subsp. lactis HN019, and polydextrose (Litesse) daily for 2 weeks modestly improves clinical response and reduces transit time when compared with taking a control yogurt. However, there was no effect on the number of daily bowel movements (90275). Other studies show that taking Lactobacillus acidophilus DDS-1 6.6 billion CFUs daily for 4 weeks in combination with Bifidobacterium longum UABl-14, Bifidobacterium animalis subsp. lactis UABla-12, Bifidobacterium bifidum UABb-10, and fructo-oligosaccharides (FOS) 7 mg does not improve symptoms of constipation when compared with a placebo providing FOS (110970). Also, there was a general lack of support for symptom improvement following the intake of Lactobacillus acidophilus NCFM 10 billion CFUs daily with Lacticaseibacillus paracasei Lpc-37 and Bifidobacterium animalis subsp. lactis strains Bl-04, Bi-07, and HN019 daily for 2 weeks (110979).
• Critical illness (trauma). Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in critically ill, hospitalized adults shows that taking L. acidophilus LA-5 1.75 billion colony-forming units (CFUs), Lactiplantibacillus plantarum 500 million CFUs, Bifidobacterium animalis subsp. lactis BB12 1.75 billion CFUs, and Saccharomyces boulardii 1.5 billion CFUs twice daily for 15 days modestly reduces the risk of sepsis, as well as the length of stay in the ICU and hospital, when compared with placebo (107524).
• Denture stomatitis. Although there has been interest in using oral Lactobacillus acidophilus for denture stomatitis, there is insufficient reliable information about the clinical effects of L. acidophilus for this condition.
• Depression. Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in patients with major depression shows that taking L. acidophilus, Lacticaseibacillus casei, and Bifidobacterium bifidum daily for 8 weeks reduces symptoms of depression measured on the Beck Depression Inventory (BDI) when compared with placebo (99780). However, the validity of the results from this study is limited by incomplete reporting. For example, patient baseline BDI scores were not reported.
• Diabetes. Oral Lactobacillus acidophilus in combination with other probiotic species seems to be beneficial for the treatment of gestational diabetes, although it is unclear if it is beneficial for treatment of type 1 or type 2 diabetes. Oral L. acidophilus is unlikely to be beneficial for the prevention of gestational diabetes. Details: Although some individual studies disagree, meta-analyses of clinical research in patients with gestational diabetes show that taking probiotics, most often L. acidophilus in combination with other species, improves glycemic indices such as fasting blood glucose and insulin sensitivity when compared with placebo (102288,104156). Also, one meta-analysis of clinical research shows that taking probiotics specifically containing L. acidophilus in combination with other species modestly improves these glycemic indices, as well as levels of total cholesterol and triglycerides, but not low-density lipoprotein (LDL) or high-density lipoprotein (HDL) cholesterol (111796). Some doses used in available studies include a combination of freeze-dried L. acidophilus, Lacticaseibacillus casei, and Bifidobacterium bifidum each as 2 billion colony-forming units (CFUs) per gram daily for 6 weeks (95416,98430), a total of 4 billion CFUs of a combination of L. acidophilus LA-5, Bifidobacterium animalis subsp. lactis BB-12, Streptococcus thermophilus STY-31, and Lactobacillus delbrueckii subsp. bulgaricus LBY-27 for 8 weeks starting at 24-28 weeks' gestation (96892), and a specific product containing L. acidophilus and 7 other probiotics (Visbiome, ExeGi Pharma) as a total of 112.5 billion CFUs twice daily for 8 weeks (107549). Meta-analyses in patients with gestational diabetes show that taking probiotics such as L. acidophilus does not reduce the risk for caesarean section birth, neonatal hypoglycemia, large for gestational age birth, or hypertensive disorders such as pregnancy-induced hypertension, pre-eclampsia, or eclampsia (102288,104156,111796). However, one meta-analysis of clinical research shows that taking probiotics specifically containing L. acidophilus modestly reduces neonatal birth weight, but not maternal weight gain (111796). Taking L. acidophilus does not seem to be effective for PREVENTING gestational diabetes. A large clinical trial shows that taking L. acidophilus LA1 7.5 billion CFUs, Bifidobacterium longum sp54 cs 1.5 billion CFUs, and Bifidobacterium bifidum sp9 cs 6 billion CFUs daily from 14-24 weeks' gestation does not reduce the incidence of gestational diabetes when compared with taking placebo (107520). Research on the use of L. acidophilus for type 2 diabetes is mixed. Taking a combination of L. acidophilus, Bifidobacterium bifidum, and Streptococcus thermophilus daily for 12 weeks does not reduce levels of fasting blood glucose or glycated hemoglobin (HbA1c) when compared with placebo (107521). One clinical study shows that taking L. acidophilus along with six other probiotic strains (Familact) daily for 6 weeks reduces fasting blood glucose, but does not affect plasma insulin, when compared with placebo (99790). A small clinical trial shows that taking fermented goat milk 120 grams containing one billion CFUs each of L. acidophilus La-5 and Bifidobacterium animalis subsp. lactis BB-12 daily for 6 weeks modestly reduces levels of HbA1c and low-density lipoprotein (LDL) cholesterol, but not fasting blood glucose or insulin resistance, when compared with conventional fermented milk containing Streptococcus thermophilus TA-40 (110973). However, other clinical research shows that taking L. acidophilus 1 billion CFUs, along with Lacticaseibacillus rhamnosus, Bacillus coagulans GanedenBC30 (GBI-30, 6086), and fructo-oligosaccharides 500 mg daily for 12 weeks modestly reduces fasting blood glucose and insulin and improves measures of insulin resistance when compared with placebo (107731). Another clinical trial shows that taking yogurt 200 grams daily containing L. acidophilus 4.65 million CFUs per gram along with Bifidobacterium animalis subsp. lactis modestly reduces levels of HbA1c, triglyceride, and LDL cholesterol, but not fasting glucose, when compared with a placebo yogurt (111798). A combination probiotic containing L. acidophilus has also been evaluated in children 2-12 years of age with new-onset type 1 diabetes. One clinical study shows that taking a specific combination product (Visbiome, ExeGi Pharma) providing 112.5 billion CFUs daily for 3 months modestly decreases HbA1c and insulin requirements when compared with placebo. Also, about three times as many children achieved remission, defined as insulin requirements of less than 0.5 U/kg daily and HbA1c less than 7%. However, C-peptide levels and the maintenance of residual pancreatic beta-cell function were not affected when compared with placebo (107497).
• Diabetic nephropathy. Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in patients with diabetic nephropathy not taking antidiabetes drugs shows that taking a combination of L. acidophilus, Bifidobacterium bifidum, and Streptococcus thermophilus daily for 12 weeks modestly reduces the ratio of microalbuminuria/creatinine (mAlb/Cr), a marker of kidney damage, when compared with placebo. However, there was no effect on the estimated glomerular filtration rate (eGFR) (107521).
• Diarrhea. Oral heat-killed L. acidophilus seems to reduce the duration of diarrhea in adults and children. Oral live L. acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in children with dysentery being treated with ceftriaxone shows that taking a specific combination probiotic sachet (Kidilact, Zisttakhmir Company) containing live L. acidophilus, Lacticaseibacillus casei, Lacticaseibacillus rhamnosus, Lactobacillus delbrueckii subsp. bulgaricus, Bifidobacterium longum subsp. infantis, Bifidobacterium breve, and Streptococcus thermophilus daily for 5 days modestly reduces the duration of diarrhea, hospitalization, and blood in diarrhea when compared with control (102417). Heat-killed L. acidophilus has also been investigated for the treatment of diarrhea. A meta-analysis of four small clinical studies in infants and children ages 1 month to 4 years shows that taking heat-killed L. acidophilus LB 20-30 billion colony-forming units (CFUs) daily for up to 5 days along with oral or intravenous rehydration therapy can modestly reduce the duration of diarrhea, primarily of non-rotaviral origin (90295). Also, preliminary clinical research in patients with functional chronic diarrhea shows that taking heat-killed L. acidophilus LB (Lacteol Fort, Laboratoire du Lacteol du Dr Boucard) as two capsules twice daily for a total of 20 billion cells daily for 4 weeks reduces daily stool frequency by 3.5, compared with a reduction of 1.2 in patients taking five chewable capsules three times daily of an unspecified strain of L. acidophilus (Lacidophilin, Tai Ge Pharma Ltd). Stool consistency, pain, distention, and total efficacy, defined as a decrease in mean symptoms by at least 40%, were also further improved in patients taking the heat-killed product (107537). However, other clinical research in children ages 6 months to 12 years hospitalized with acute diarrhea shows that taking 15 billion heat-killed L. acidophilus (Lactrol, Raptakos) cells daily for 3 days along with oral rehydration solution (ORS) does not have beneficial effects on duration of diarrhea, frequency of stools, or length of hospital stay, when compared with ORS alone (111789). The European Society for Pediatric Infectious Diseases recommends probiotics in hospitalized children with diarrhea (98469) and the Infectious Disease Society of America (IDSA) recommends probiotics for the outpatient treatment of acute diarrhea (95388) However, L. acidophilus is not a specific focus of the guidelines and most evidence is low quality.
• Generalized anxiety disorder (GAD). Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical trial in patients newly diagnosed with GAD shows that taking sertraline 25 mg plus probiotics daily for 8 weeks may modestly reduce some symptoms of anxiety when compared with sertraline alone. However, the reduction in anxiety score was small and change was not consistent between rating scales. Also, the quality of life was not improved. The probiotics provided a total of 18 billion colony-forming units of L. acidophilus, Bifidobacterium bifidum, Bifidobacterium longum, and Bifidobacterium animalis subsp. lactis (110977).
• Hepatic encephalopathy. Although there has been interest in using oral Lactobacillus acidophilus for hepatic encephalopathy, there is insufficient reliable information about the clinical effects of L. acidophilus for this condition.
• HIV/AIDS. Although there has been interest in using oral Lactobacillus acidophilus for HIV/AIDS, there is insufficient reliable information about the clinical effects of L. acidophilus for this condition.
• Hypercholesterolemia. It is unclear if oral Lactobacillus acidophilus is beneficial for lowering cholesterol levels; the available research is conflicting. Details: Two meta-analyses of clinical research show that taking fermented milk products containing L. acidophilus can reduce total cholesterol by about 14-19 mg/dL in adults with or without hypercholesterolemia. However, the effect of L. acidophilus on both total and LDL cholesterol levels is conflicting from available research (95396,95397,95399). Clinical trials included in these meta-analyses evaluated patients with hypercholesterolemia, type 2 diabetes, nonalcoholic fatty liver disease (NAFLD), metabolic syndrome, and others. Taking L. acidophilus does not appear to improve high-density lipoprotein (HDL) cholesterol or triglyceride levels (95396,95397,95399). Doses used in some studies have included fermented milk products providing L. acidophilus 39 million to 2 billion CFUs daily, alone or along with other probiotic species, for up to 6 weeks (95396). One small clinical trial in patients with hypercholesterolemia shows that taking L. acidophilus LA-1 60 billion colony-forming units (CFUs) three times daily for 6 weeks does not affect serum lipids when compared with taking placebo (111791). A meta-analysis of nine small to moderate-sized clinical studies shows that taking a combination of L. acidophilus and Bifidobacterium animalis subsp. lactis reduces levels of total cholesterol when compared with placebo (107591). However, it is unclear if this is due to L. acidophilus, Bifidobacterium animalis subsp. lactis, or their combination.
• Hypertension. Although there has been interest in using oral Lactobacillus acidophilus for hypertension, there is insufficient reliable information about the clinical effects of L. acidophilus for this condition.
• Inflammatory bowel disease (IBD). Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small preliminary clinical trial in patients with collagenous colitis shows that taking 10 billion colony-forming units each of L. acidophilus LA-5 and Bifidobacterium longum subsp. lactis BB-12 twice daily for 12 weeks does not increase the proportion of patients with a reduction in weekly bowel frequency of at least 50% when compared with placebo. Also, there was no effect of this combination on stool consistency or abdominal symptoms. However, there were some modest benefits when compared with baseline (110999). This study was small and may have been underpowered to detect differences.
• Intraventricular hemorrhage. Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in premature infants shows that taking 6 billion CFUs of a combination of L. acidophilus NCDO 1748 and Bifidobacterium bifidum NCDO 2203 (UFC Inforan, Switzerland) from 7 days of age until 34 weeks postmenstrual age or discharge does not reduce the odds of intraventricular hemorrhage when compared with a control group of infants not given these probiotics. The infants in this study were born at less than 32 weeks gestation and had a birthweight of less than 1500 grams (111794). This study is limited by the lack of randomization to treatment group; placement was based on year of birth.
• Lactose intolerance. It is unclear if oral Lactobacillus acidophilus is beneficial for lactose intolerance. Details: One small clinical trial shows that consuming 400 mL of a non-fermented milk product containing L. acidophilus 530 million colony-forming units (CFUs)/mL daily does not reduce symptoms of lactose intolerance or hydrogen breath test results when compared with milk without L. acidophilus (16737). Another small preliminary clinical trial shows that taking L. acidophilus BG2FO4 10 billion CFUs twice daily for 7 days does not reduce lactose-induced gastrointestinal symptoms or improve lactose digestion based on breath hydrogen when compared with baseline (111783). However, another clinical trial shows that adding various L. acidophilus strains 800 million to 1 billion CFUs/mL to non-fermented milk improves hydrogen breath tests in patients with lactose intolerance (16738).
• Lyme disease. Although there has been interest in using oral Lactobacillus acidophilus for Lyme disease, there is insufficient reliable information about the clinical effects of L. acidophilus for this condition.
• Metabolic syndrome. Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in elderly patients with metabolic syndrome shows that taking a combination of L. acidophilus PBS066-DSM 24,936, Lactiplantibacillus plantarum PBS067-DSM 24,937, and Limosilactobacillus reuteri PBS072-DSM 25,175 as 2 billion colony-forming units (CFUs) each, with inulin and fructo-oligosaccharides daily for 60 days, reduces the number of patients diagnosed with metabolic syndrome by 23%, compared with a 10% reduction in those taking placebo. In the probiotic group, there were modest improvements in waist circumference and levels of fasting plasma insulin, total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, triglycerides, and inflammatory mediators when compared with placebo. However, there were no significant differences between groups for fasting blood glucose or blood pressure. All patients in this study were on a Mediterranean-like standard diet (107560).
• Necrotizing enterocolitis (NEC). It is unclear if oral Lactobacillus acidophilus is beneficial or safe for NEC prevention. Details: Most meta-analyses of clinical research show that giving lactobacilli enterally reduces the risk of NEC and/or severe NEC in preterm, mainly very low birth weight (VLBW), infants. Some meta-analyses support the use of lactobacilli in combination with bifidobacteria, as opposed to lactobacilli alone for reducing the risk of NEC. However, only a small number of the individual studies included in these analyses have investigated the effects of L. acidophilus, which was used as part of a combination probiotic and/or prebiotic product in all cases (95344,95351,103437,103445,104157,105162,105164). Also, guidance among regulatory agencies and clinical organizations varies with respect to the use of probiotics in very low birth weight infants under 1000 grams. The US Food and Drug Administration (FDA) warns that preterm infants given probiotics are at risk of serious infections caused by the bacteria or fungi contained in probiotics due to cases reported in this group of infants (111610). Also, The American Academy of Pediatrics does not support the routine administration of probiotics to preterm infants, particularly those with a birth weight below 1000 grams, due to conflicting data on safety and efficacy and potential for harm in this vulnerable population (111608). The Canadian Paediatric Society, the American Gastroenterological Association, and the European Society for Paediatric Gastroenterology, Hepatology and Nutrition state that probiotic combinations may be of benefit in reducing the incidence of NEC in preterm neonates over 1000 grams. However, L. acidophilus is not specifically recommended (103003,111609,111611).
• Nonalcoholic fatty liver disease (NAFLD). Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: In children with NAFLD, clinical research shows that taking a specific combination product (Prokid, Gostaresh Milad Pouya Company) containing L. acidophilus ATCC B3208 3 billion colony-forming units (CFUs), Lacticaseibacillus rhamnosus DSMZ 21690 2 billion CFUs, Bifidobacterium animalis subsp. lactis DSMZ 32269 6 billion CFUs, and Bifidobacterium bifidum ATCC SD6576 2 billion CFUs daily for 12 weeks normalizes liver sonography findings in 53% of children, compared with 17% of those taking placebo. In addition, levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) are reduced by 30% and 25%, respectively. There was no effect on body mass index or blood lipids when compared with placebo (105156). Another clinical trial shows that taking two sachets daily for 3 months of a specific combination product (VSL#3) containing L. acidophilus and other probiotics modestly decreases triglyceride levels and liver enzymes when compared with taking placebo. However, there was no change in body mass index or most glycemic or lipid parameters (111009). However, taking L. acidophilus in combination with other probiotics does not seem to be beneficial in adults with NAFLD. Clinical research shows that taking yogurt 100 grams, containing L. acidophilus La-5 and Bifidobacterium animalis subsp. lactis Bb-12 40 million CFUs and vitamin D 1000 IU, daily for 3 months does not improve fasting blood glucose levels, insulin levels, blood pressure, or anthropometric indices when compared with unfortified yogurt (105174). Also, a small clinical trial shows that taking a combination of L. acidophilus BCMC 12,130, Lacticaseibacillus casei BCMC 12,313, Lactobacillus delbrueckii subsp. lactis BCMC 12,451, Bifidobacterium bifidum BCMC 02290, Bifidobacterium longum subsp. infantis BCMC 02129, and Bifidobacterium longum BCMC 02120 30 billion colony-forming units twice daily for 6 months has no beneficial effects on hepatic steatosis or fibrosis or on levels of liver enzymes, blood lipids, or fasting glucose, when compared with placebo (107523).
• Nonalcoholic steatohepatitis (NASH). Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical trial in patients with NASH shows that taking 1 billion colony-forming units each of L. acidophilus ATCC SD5221 and Bifidobacterium animalis subsp. lactis HN019 daily for 6 months does not have beneficial effects on severity of liver fibrosis or steatosis, metabolic markers, or inflammation when compared with taking placebo. The effect of this combination on liver enzymes was mixed (111797).
• Obesity. Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: In combination with Bifidobacterium animalis subsp. lactis BS01, taking L. acidophilus LA02 2 billion colony-forming units (CFUs) daily for 6 weeks does not reduce body weight or body fat when compared with placebo in young, healthy females, only some of whom were overweight (103438). However, another clinical study shows that taking 50 billion CFUs of a specific combination of L. acidophilus, Lactiplantibacillus plantarum, Bifidobacterium bifidum, and B. animalis subsp. lactis (Lab4P) for 24 weeks reduces body weight by an additional 1.3 kg more than placebo (103439).
• Polycystic ovary syndrome (PCOS). Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: In patients with PCOS, clinical research shows that taking a combination of L. acidophilus T16 (IBRC-M10785), Lacticaseibacillus casei T2 (IBRC-M10783), and Bifidobacterium bifidum T1 (IBRC-M10771) 2 billion colony-forming units each, plus inulin 800 mg, daily for 12 weeks modestly reduces serum insulin and triglyceride levels and improves insulin resistance and insulin sensitivity when compared with placebo. However, it does not alter cholesterol or fasting glucose levels (105159). Another clinical trial shows that 31.3% of patients with PCOS taking L. acidophilus in combination with other probiotics daily for 6 months had regular menstrual cycles compared with 12.5% of those taking placebo. There were also modest improvements in testosterone levels and waist circumference, but not other hormones, insulin resistance, body weight, or most measures of quality of life. The product provided Lactobacillus acidophilus UBLA-34 2 billion CFUs along with Bifidobacterium bifidum UBBB-55, Lactiplantibacillus plantarum UBLP-40, Lacticaseibacillus casei UBLC-42, Limosilactobacillus fermentum UBLF-31, Lacticaseibacillus rhamnosus UBLR-58, Limosilactobacillus reuteri UBLRu-87, and fructo-oligosaccharides (FOS) daily for 2 months and then twice daily for 4 months. All patients also underwent dietary and lifestyle changes (110974).
• Postoperative infection. Although there has been interest in using oral Lactobacillus acidophilus for preventing postoperative infections, there is insufficient reliable information about the clinical effects of lactobacillus for this purpose.
• Pouchitis. Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Continuous oral treatment for one year with a specific concentrated formulation of L. acidophilus and other probiotics (Visbiome, ExeGi Pharma) as 6 grams (300-500 billion live bacteria per gram), daily for up 12 months seems to maintain remission of pouchitis in 85% of patients (6087,12769). Also, one small clinical study shows that taking a specific product (Trilac, Allergon AB) containing L. acidophilus 600 million colony-forming units (CFUs) per capsule, Lactobacillus delbrueckii subsp. bulgaricus 400 million CFUs per capsule, and Bifidobacterium bifidum 600 million CFUs per capsule, taken in doses of two capsules three times daily for 9 months, can reduce pouchitis severity and the number of patients experiencing pouchitis when compared to baseline (90296). The validity of these findings is limited by the lack of a comparator group.
• Pregnancy-induced nausea and vomiting. Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small preliminary clinical trial shows that taking probiotics during pregnancy reduces the severity and duration of nausea and vomiting by 16% to 54%. There was also a small benefit on stool hardness. A specific probiotic (Probiotics 10, Nature's Bounty) was taken as 2 capsules daily for two back-to-back cycles of six days with probiotics and two days without. Each capsule contained a total of 10 billion colony-forming units (CFUs) of L. acidophilus La-14, Lactiplantibacillus plantarum 299v and DSM 15312, Lactobacillus delbrueckii subsp. bulgaricus Lb-87, Lacticaseibacillus paracasei DSM 13434 and Lpc-37, Ligilactobacillus salivarius Ls-33, Levilactobacillus brevis Lbr-35, Lacticaseibacillus casei Lc-11, and Bifidobacterium animalis subsp. lactis Bl-04, along with inulin 200 mg (107199).
• Prematurity. Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: In premature infants, clinical research shows that taking a blend of L. acidophilus, bifidobacteria, and Enterococcus faecalis (Peifeikang powder, Shanghai Xinyi Pharmaceutical Company), at least 5 million colony-forming units (CFUs) three times daily from birth until implementation of total parenteral nutrition, reduces the rate of development of extrauterine growth retardation from 15% to 8% when compared with those not receiving this blend (103448). Other preliminary clinical research in premature infants shows that taking 6 billion CFUs of a combination of L. acidophilus NCDO 1748 and Bifidobacterium bifidum NCDO 2203 (UFC Inforan, Switzerland) from 7 days of age until 34 weeks postmenstrual age or discharge reduces the odds of neurodevelopment impairment at 24 months corrected age by 70% when compared with a control group of infants not given these probiotics. The odds of having moderate to severe impairment were also reduced. The infants in this study were born at less than 32 weeks gestation and had a birthweight of less than 1500 grams (111794). This study is limited by the lack of randomization to treatment group; placement was based on year of birth. Observational research has also been conducted. One large observational study in infants fed strictly human milk, but not strictly formula or a combination, suggests that taking L. acidophilus 1 to 3 billion CFUs with Bifidobacterium longum subsp. infantis during the first month of life for the prevention of necrotizing enterocolitis was associated with a modest increased weight gain velocity. The infants in this study were born between 22-29 weeks gestation and had a birthweight of less than 1500 grams (111771).
• Psoriasis. Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in patients with psoriasis shows that taking a mixture of probiotics for 8 weeks modestly improves overall symptoms and feelings of depression when compared with placebo. The percentage of patients achieving at least a 50% or 75% reduction in overall symptom score was 40% and 24%, respectively, in those taking the probiotic mixture, compared with 16% and 8% of those taking placebo. Each probiotic capsule was used twice daily and provided a total daily dose of 2.6 billion colony-forming units (CFUs) of L. acidophilus, Bifidobacterium bifidum, Bifidobacterium animalis subsp. lactis, and Bifidobacterium longum (107498).
• Radiation-induced diarrhea. Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in patients with cervical cancer receiving radiotherapy with or without chemotherapy shows that taking a specific product (Biogurt, Fame Pharmaceuticals) containing L. acidophilus LA-5 and Bifidobacterium animalis subsp. lactis BB-12 as 1.75 billion lyophilized colony-forming units (CFUs) as a capsule three times daily throughout treatment reduces the risk of diarrhea by 28% when compared with placebo. The treatment group also used less loperamide (102285). Another small clinical trial in patients undergoing pelvic radiotherapy with weekly cisplatin shows that taking L. acidophilus and Bifidobacterium bifidum (Infloran, Laboratio Farmaceutico SIT) as 1 billion CFUs each, twice daily from seven days before starting radiotherapy and continuing during radiotherapy, reduces the incidence of moderate to severe diarrhea and the need for antidiarrheal medication when compared with placebo. Moderate to severe diarrhea occurred in 9% of patients using the probiotics, compared with 45% of those taking placebo (107580).
• Respiratory tract infections. Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in children ages 3-5 years who attend daycare centers shows that taking a combination milk product containing 5 billion colony-forming units (CFUs) each of L. acidophilus and Bifidobacterium animalis (HOWARU Protect, Danisco) reduces the risk of experiencing fever, cough, and rhinorrhea by 45% when compared with placebo. Patients taking this combination experienced an average 2-day shorter duration of symptoms and were significantly less likely to use an antibiotic for their symptoms. Patients who took L. acidophilus without bifidobacterium also had a reduction in fever, cough, and use of antibiotics, but not rhinorrhea (16847). In healthy children aged 3-10 years, clinical research shows that taking 12.5 billion CFUs daily of a specific combination of L. acidophilus CUL21 and CUL60, Bifidobacterium bifidum CUL20, Bifidobacterium animalis subsp. lactis CUL34 (Lab4), and vitamin C 50 mg daily reduces the risk of cough by 16% and sore throat by 20%, and modestly reduces school absenteeism and antibiotic use when compared with placebo. However, nasal symptoms, fever, and wheezing were not reduced (106943). A different combination product containing L. acidophilus DDS-1 1 billion CFUs and B. animalis subsp. lactis UABLA-12 4 billion CFUs (Up4-Junior, UAS Laboratories) with fructo-oligosaccharides 50 mg has also been evaluated. Clinical research in children 3-12 years of age with a sick household member shows that taking this product daily for 2 weeks modestly shortens the duration of respiratory infections, but does not reduce the risk of developing an infection, when compared with placebo (98439). In overweight adults or adults with obesity, taking 50 billion CFUs of a specific combination of L. acidophilus, Lactiplantibacillus plantarum, B. bifidum, and B. animalis subsp. lactis (Lab4P) for 24 weeks reduces the overall likelihood of having upper respiratory tract infection symptoms, such as sneezing, cough, and blocked nose, by approximately 40% when compared with placebo (103439).
• Retinopathy of prematurity. Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in premature infants shows that taking 6 billion CFUs of a combination of L. acidophilus NCDO 1748 and Bifidobacterium bifidum NCDO 2203 (UFC Inforan, Switzerland) from 7 days of age until 34 weeks postmenstrual age or discharge does not reduce the odds of retinopathy of prematurity when compared with a control group of infants not given these probiotics. The infants in this study were born at less than 32 weeks gestation and had a birthweight of less than 1500 grams (111794). This study is limited by the lack of randomization to treatment group; placement was based on year of birth. Also, one large observational study in premature infants suggests that taking L. acidophilus 1 to 3 billion CFUs with Bifidobacterium longum subsp. infantis during the first month of life for the prevention of necrotizing enterocolitis was not associated with a reduced risk of retinopathy of prematurity. The infants in this study were born between 22-29 weeks gestation and had a birthweight of less than 1500 grams (111771).
• Rheumatoid arthritis (RA). Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One small clinical study in patients with moderate-to-severe RA shows that taking capsules containing freeze-dried strains of L. acidophilus, Lacticaseibacillus casei, and Bifidobacterium bifidum daily for 8 weeks does not improve RA severity, the number of tender or swollen joints, or joint pain when compared with placebo (95418).
• Rotaviral diarrhea. It is unclear if oral Lactobacillus acidophilus is beneficial for rotaviral diarrhea. Details: One preliminary clinical study shows that taking a combination of L. acidophilus AD031 2 billion colony-forming units (CFUs) and Bifidobacterium longum BORI 20 billion CFUs twice daily for 3 days reduces the duration of rotaviral diarrhea by an average of 3 days when compared with placebo (95334). However, one clinical study using a lower dose and different strain of L. acidophilus (La-14) 200 million CFUs twice daily for 5 days shows that this regimen does not reduce the duration of watery diarrhea or affect the viral load in children aged 9 months to 5 years with confirmed norovirus or rotavirus infection (96887). A small clinical study shows that heat-killed L. acidophilus LB 20-30 billion cells daily for up to 4 days can modestly reduce the duration of diarrhea in infants and children, some of which had confirmed rotavirus (90295).
• Sepsis. Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in premature infants shows that taking 6 billion CFUs of a combination of L. acidophilus NCDO 1748 with Bifidobacterium bifidum NCDO 2203 (UFC Inforan, Switzerland) from 7 days of age until 34 weeks postmenstrual age or discharge reduces the odds of late onset sepsis by 55% when compared with a control group of infants not given these probiotics. The infants in this study were born at less than 32 weeks gestation and had a birthweight of less than 1500 grams (111794). This study is limited by the lack of randomization to treatment group; placement was based on year of birth. One large observational study in infants fed a mix of human milk and formula, but not strictly human milk or formula, suggests that taking L. acidophilus 1 to 3 billion CFUs with Bifidobacterium longum subsp. infantis during the first month of life for the prevention of necrotizing enterocolitis was associated with a 31% reduction in the development of clinical sepsis. The infants in this study were born between 22-29 weeks gestation and had a birthweight of less than 1500 grams (111771).
• Short bowel syndrome. Although there has been interest in using oral Lactobacillus acidophilus for short bowel syndrome, there is insufficient reliable information about the clinical effects of lactobacillus for this condition.
• Small intestinal bacterial overgrowth (SIBO). Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in children with chronic diarrhea due to SIBO shows that taking a combination of lyophilized L. acidophilus 1.5 grams and Lacticaseibacillus casei 1.5 grams by mouth twice daily for 21 days decreases average daily stools by 1.5, but does not improve other symptoms, when compared with placebo (91143). Also, one preliminary clinical study shows that taking a total of 2 billion CFUs of L. acidophilus and Lacticaseibacillus rhamnosus (Lacidofil) daily for 4 weeks does not prevent the development of SIBO in children that started treatment with omeprazole 20 mg daily for epigastric pain (90262).
• Travelers' diarrhea. It is unclear if oral Lactobacillus acidophilus is beneficial for the prevention of travelers' diarrhea. Details: A meta-analysis which included three clinical studies evaluating the use of L. acidophilus in adults traveling to different parts of the world found no benefit for the prevention of travelers' diarrhea when compared with placebo (101445). The effectiveness of this species may vary significantly based upon the destination of travel. Destinations in the same country can have different results, probably due to differences in bacteria and other microorganisms at different locations (10216).
• Ulcerative colitis. Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: The best evidence of benefit is for a specific combination product (Visbiome, ExeGi Pharma). Doses of 3 grams (equivalent to 900 billion colony-forming units (CFUs)) once or twice daily have been used in combination with conventional treatment. In children aged 1-16 years, doses of 450-1800 billion CFUs for up to one year have been used (3261,14370,14371,16841,95337). A meta-analysis of clinical research shows that taking this product as an adjunct to standard ulcerative colitis treatment can increase remission rates in adults and children by about 1.7-fold when compared with standard treatment alone (95337). Preliminary clinical research in patients with moderate to severe symptoms taking mesalazine 1200 mg daily shows that taking an unknown dose of L. acidophilus twice daily along with Bifidobacterium bifidum BGN4 and Ligilactobacillus salivarius (Acronelle, Bromatech srl, Milan, Italy) for 2 years modestly improves patient- and physician-scales of overall symptoms when compared with taking mesalazine alone. There were also improvements in stool frequency and rectal bleeding (110981). Although some contradictory evidence exists (3261,16841), most research shows that taking Visbiome or a combination of L. acidophilus LA-5 and Bifidobacterium animalis subsp. lactis BB-12 (Probio-Tec AB-25) does not prevent relapse in people who are already in remission (95337,95338).
• Urinary tract infections (UTIs). Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: In children aged 4 months to 5 years with a previous UTI, clinical research shows that taking a specific combination of L. acidophilus, Lacticaseibacillus rhamnosus, Bifidobacterium bifidum, and Bifidobacterium animalis subsp. lactis (Complete Probiotic Platinum) for 18 months increases the median time to the first incidence of recurrence by approximately 3 months and increases the percentage of children without a UTI during the study period from 83% to 97% (103436).
• Vaginal candidiasis. It is unclear if oral or intravaginal Lactobacillus acidophilus is beneficial for vaginal candidiasis. Details: In a small preliminary clinical trial in patients with recurrent vulvovaginal candidiasis who had undergone a week of oral fluconazole treatment followed by intravaginal L. acidophilus LA 02 and Limosilactobacillus fermentum LF10, 72.4% of patients demonstrated a lack of clinical recurrence over a 7 month observational period. All patients took fluconazole 200 mg three times in the first week followed by intravaginal application with at least 0.4 billion colony-forming units each of L. acidophilus LA 02 and Limosilactobacillus fermentum LF10, along with arabinogalactan and fructo-oligosaccharides (FOS) on alternate days for 10 days and then once weekly for 10 weeks (111781). However, a combination of L. acidophilus, Lacticaseibacillus rhamnosus, Lactobacillus delbrueckii, and Streptococcus thermophilus (Femilac) given intravaginally, does not seem to reduce the risk of vaginal candidiasis infection following use of antibiotics (12108). There is also some evidence that eating yogurt enriched with L. acidophilus daily does not reduce the risk of recurrent vaginal candidiasis (1245).
• Ventilator-associated pneumonia (VAP). Oral Lactobacillus acidophilus has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research shows that taking L. acidophilus LA-5 1.75 billion colony-forming units (CFUs), Lactiplantibacillus plantarum 500 million CFUs, Bifidobacterium animalis subsp. lactis BB12 1.75 billion CFUs, and Saccharomyces boulardii 1.5 billion CFUs twice daily for 15 days reduces the risk of VAP to 12%, compared with 28% in those taking placebo. Half of the dose was given onto the oropharynx and half via a nasogastric tube (107524). More evidence is needed to rate Lactobacillus acidophilus for these uses.

• Diabetes. It is unclear if oral stevia is beneficial in patients with diabetes; the available research is conflicting. Details: A small single-dose study shows that taking stevia leaf extract 1000 mg, standardized to contain 91% stevioside, along with a meal reduces postprandial glucose levels by 18% in adults with type 2 diabetes when compared with a starch control (11812). However, clinical research in patients with type 1 or type 2 diabetes shows that taking stevioside 250 mg three times daily for 3 months does not affect blood glucose levels or glycated hemoglobin (HbA1C) when compared with baseline (16705). Also, a small clinical study in patients with diabetes shows that drinking 200 mL of black tea, sweetened with stevia extract 2%, three times daily for 8 weeks does not affect glycemic indices when compared with drinking tea sweetened with sucralose (103695).
• Hypertension. It is unclear if oral stevia is beneficial in patients with hypertension; the available research is conflicting. Details: Some clinical research in patients with mild to moderate hypertension shows that taking stevioside, a constituent of stevia, 750-1500 mg in three divided doses daily reduces systolic blood pressure by 10-14 mmHg and diastolic blood pressure by 6-14 mmHg within one week to three months of treatment initiation and continuing for up to 2 years (11809,11810). However, other clinical research in patients with mild hypertension shows that taking stevioside in doses up to 15 mg/kg daily does not significantly reduce blood pressure (16706).
• Obesity. It is unclear if oral stevia is beneficial in patients with obesity; the available research is conflicting. Details: Although a small clinical study in healthy adults shows that drinking water with stevia (Truvia) 245 ppm as a single dose reduces appetite and energy intake when compared with drinking water alone (103697), other small, single-dose studies have shown no effect of stevia 15.3 mg or 1 gram as a single dose on satiety, energy intake, or fullness when compared with either water alone or a non-nutritive sweetener (103696,110124). A small clinical study in healthy adults shows that taking an aqueous stevia leaf extract (SweetLeaf) twice daily for 12 weeks does not affect body weight, compared with an increase in weight in the control group. This suggests that stevia extract may have attenuated weight gain in this study (106458). More evidence is needed to rate stevia for these uses.

• Cardiovascular disease (CVD). Pooled analyses of clinical research show that taking freeze-dried strawberry powder or eating fresh strawberries for 3-12 weeks can reduce levels of C-reactive protein, a marker of inflammation and risk factor for CVD, by 0.47-0.63 mg/L when compared with placebo. These analyses report conflicting effects on blood pressure and lipid levels (103881,103882), with one analysis reporting small improvements that are not clinically significant (103881). It is unclear whether strawberry can prevent CVD or related outcomes.
• Diabetes. Preliminary clinical research in adults with type 2 diabetes shows that taking freeze-dried strawberry powder 50 grams daily for 6 weeks reduces glycated hemoglobin (HbA1c) by 0.47% compared to an increase of 0.15% with placebo. However, there were no changes in serum glucose, anthropometric measurements, blood lipids, or blood pressure. Also, the short duration of supplementation makes it unclear whether the change in HbA1c was due to strawberry (100113,100119).
• Hyperlipidemia. Data on the effects of strawberry on serum lipids are conflicting. Clinical research in adults with abdominal obesity and elevated serum lipids shows that taking freeze-dried strawberry powder 50 grams daily for 12 weeks reduces total and low-density lipoprotein (LDL) cholesterol when compared with either placebo or taking 25 grams of freeze-dried strawberry daily. In those taking 50 grams daily, levels of LDL cholesterol decreased by approximately 21% from baseline, compared with a 2% reduction in those taking placebo. However, strawberry did not improve levels of high-density lipoprotein (HDL) cholesterol or triglycerides (100109). Another study also reported reduced levels of total and LDL cholesterol (112318), while others report no changes in any lipid levels (112320,112321). In a meta-analysis, strawberry was associated with mean decreases of 11 mg/dL in LDL levels, and 12 mg/dL in total cholesterol, as well as increases in high-density lipoprotein (HDL) cholesterol (112323).
• Hypertension. Preliminary clinical research in postmenopausal women with pre- or stage I hypertension shows that taking freeze-dried strawberry powder 25 or 50 grams daily for 8 weeks does not reduce blood pressure when compared with placebo. However, over 50% of the included women were also taking at least one blood pressure lowering medication (100111).
• Obesity. Clinical research in adults with obesity or abdominal obesity and elevated serum lipids shows that taking freeze-dried strawberry powder 50 grams daily for 12 weeks does not reduce body weight or adiposity when compared with either placebo or freeze-dried strawberries 25 grams daily (100109,100116). Similarly, preliminary clinical research in adults with type 2 diabetes who are overweight or obese shows that taking freeze-dried strawberry powder 50 grams daily for 6 weeks does not improve weight loss when compared with placebo (100113). Evidence from mainly small, lower-quality studies is mixed as to whether taking strawberries has beneficial effects on cardiovascular risk factors when compared to control in obese individuals (100109,100116,100118).
• Osteoarthritis. Preliminary clinical research in obese adults with osteoarthritis shows that taking freeze-dried strawberry powder 50 grams daily for 12 weeks reduces some, but not all, measures of pain by up to 45%, compared to no change in those taking placebo (100116). More evidence is needed to rate strawberry for these uses.

General ...In food amounts, apple cider vinegar is well tolerated. It seems to be well tolerated when used orally, short-term for medicinal purposes. However, in larger amounts, long-term use may be unsafe.
Topically, apple cider vinegar may be unsafe.
Serious Adverse Effects (Rare):
Orally: Hypokalemia, hyperreninemia, and osteoporosis have been reported with long-term use.
Topically: Chemical burns, skin irritation.

Dermatologic ...Topically, apple cider vinegar may cause chemical burns. There is one published report of an individual who developed a chemical burn caused by a single topical application of apple cider vinegar containing 5% acetic acid to the skin (91662). Another case of chemical burn has been reported for a 14-year-old patient who applied apple cider vinegar to the skin for 3 days to remove a nevi. Symptoms included erythema, irritation, and non-inflammatory skin erosion. Symptoms were treated by applying mupirocin 2% ointment twice a day for several weeks and using sunscreen on the erosion and surrounding skin (93074). In one clinical trial, use of 0.5% apple cider vinegar soaks commonly caused skin irritation. One patient in this study experienced a nonpruritic papular rash, while another patient experienced severe pruritis with burning and erosion (101172). In another report, a female had an apple cider vinegar tablet lodged in the throat for 30 minutes, resulting in tenderness and pain in the larynx and difficulty swallowing for 6 months following the incident. This was thought to be due to the acid content of the tablet (13183).

Renal ...There is one published report of an individual who developed hypokalemia, elevated renin levels, high positive urinary anion gap, and osteoporosis after ingesting apple cider vinegar 250 mL per day for 6 years. The osteoporosis was attributed to buffering of the acute acid load by bone, and the other effects were attributed to significant bicarbonate excretion (31730).

General ...Orally, Bacillus coagulans is well tolerated.
Serious Adverse Effects (Rare):
Orally: There is concern that probiotics may cause infections in some people.

Immunologic ...Since many probiotic preparations contain live and active microorganisms, there is some concern that they might cause pathogenic infection in some patients. Bacteremia and sepsis have been reported in patients with indwelling or central venous catheters or patients who are severely ill and/or immunocompromised, including preterm infants, that were using probiotic products (4380,8561,13008,13070,90298,102416,103444,105138,105140,105141)(107543,107597,107599,111610,111612,111613,111850,111852,111853). However, reports of pathogenic colonization in relatively healthy patients with intact immune systems who do not have indwelling or central venous catheters are extremely rare (4380,4389,4390,4391,4393,4398,105139,107543,107545,107546,107547).

General ...Orally, coconut is generally well tolerated.
Most Common Adverse Effects:
Orally and topically: Allergic reactions, including anaphylaxis and hives.

Dermatologic ...Orally or topically, coconut and coconut palm pollen may cause allergic skin reactions such as urticaria and hives (12359,26561,26572,95806).

Immunologic ...Although coconut is a stone fruit, in the US, coconut is grouped with tree nuts for allergen declaration purposes (107673). Orally or topically, coconut can cause allergic reactions ranging from hives to anaphylaxis in those with hypersensitivity to coconut or its pollen (12359,26561,95806,95807,95808,107673,107674). Based on a review of hospital records in the US, most reactions to coconut are due to oral exposure, including through breastfeeding, with about 50% of reactions associated with anaphylaxis (107673). In addition, there have been numerous case reports of anaphylaxis from coconut in the literature, with most cases presenting in infancy or early childhood (95808,107674). In one case report, a 12-year-old child with asthma and allergic rhinitis experienced anaphylaxis with difficulty breathing, wheezing and vomiting, from eating a piece of coconut for the first time (95808). In another case report, a 6-year-old child who had previously had urticaria and hives from applying coconut oil experienced throat swelling and anaphylaxis after eating food containing coconut (95806). Coconut may also play a role in cross-sensitization. In a case report, a 17-year-old male who experienced prickling in the mouth after ingesting coconut soon after experienced an anaphylactic reaction to buckwheat. The child was found to be sensitized to both coconut and buckwheat (95807).

General ...Orally, coconut water is well tolerated.

Gastrointestinal ...When consumed as a rehydration beverage following exercise, some people experience fullness or stomach upset (17678,95126). However, gastrointestinal distress is not reported in all studies (95139). Also, in some cases it appears to occur at a lower rate when compared with drinking plain water or drinking a carbohydrate-electrolyte rehydration fluid (17678).

Neurologic/CNS ...In one case report, a 69-year-old male died within approximately 30 hours of consuming a small amount of coconut water that was found to contain 3-nitropropionic acid due to spoilage with Arthrinium saccharicola. About 3 hours after consumption, the patient developed sweating, nausea, and vomiting, and was in a state of reduced consciousness when presenting to the hospital about 1.5 hours later. Other symptoms included confusion, dystonia, and poor balance, as well as metabolic acidosis. The coconut was pre-shaved and although refrigeration was recommended, it had been stored at room temperature for approximately one month after purchase (107670).

General ...Orally, Lacticaseibacillus paracasei is generally well tolerated.
Most Common Adverse Effects:
Orally: Mild gastrointestinal adverse effects.
Serious Adverse Effects (Rare):
Orally: There is concern that Lacticaseibacillus paracasei may cause infections in some people.

Dermatologic ...Orally, in one clinical trial, a combination of Lacticaseibacillus paracasei subsp. paracasei F19, Lactobacillus acidophilus La-5, and Bifidobacterium animalis subsp. lactis BB-12 was associated with two cases of rash, one with itching. However, it is not clear if these adverse effects were due to L. paracasei, other ingredients, the combination, or if the events were idiosyncratic (90236).
Topically, a lotion containing the cell free supernatant of L. paracasei was rarely associated with erythema, itching, and scaling (111945).

Gastrointestinal ...Orally, taking Lacticaseibacillus paracasei alone or in combination with other probiotics may cause gastrointestinal side effects including dyspepsia (105133), flatulence (107497), nausea (111952), and bloating (107497,111952); however, these events are uncommon.
There are at least five case reports of acute cholecystitis for which a lactobacilli was thought to be the primary pathogen. In a 66-year-old female, vancomycin-resistant L. paracasei was the primary pathogen resulting in peritonitis secondary to a cholecystitis-induced gallbladder perforation. Although the patient reportedly ate 96-128 oz of yogurt each day, this yogurt was not believed to be associated with the cholecystitis (103443).

Immunologic ...Since Lacticaseibacillus paracasei preparations contain live and active microorganisms, there is some concern that they might cause pathogenic infection in some patients. Lactobacilli species, including L. paracasei, have been isolated in some cases of bacteremia, sepsis, splenic abscess, endocarditis, necrotizing fasciitis, pancreatic necrosis, meningoencephalitis, and prosthetic joint infections. Most cases of L. paracasei infection are thought to be due to the translocation of bacteria from other locations in the body in which it occurs naturally, such as the oral cavity and gastrointestinal tract (107543,111942,111944,111946,90282). However, there are case reports of L. paracasei infections thought to be at least partially related to dietary or supplemental intake (90254,107546,95393). In a 77-year-old male who consumed yogurt containing L. paracasei daily, L. paracasei bacteremia with endocarditis was thought to be related to bacterial translocation from the colon following a colonoscopy (90254). In a 78-year-old male, L. paracasei bacteremia and endocarditis was thought to be related to daily use of probiotics; however, the specific species included in the product were not mentioned. Also, the patient was diagnosed with an aortic valve stenosis and had undergone dental treatment approximately 6 months previously, possibly increasing the risk for development of bacteremia (95393). In an immunocompetent 45-year-old male with no history of heart disease, consumption of yogurt containing L. paracasei for about 2.5 years was thought to be associated with the development of endocarditis (107546).

General ...Orally and intravaginally, Lactobacillus acidophilus is generally well tolerated.
Most Common Adverse Effects:
Orally: Mild gastrointestinal adverse effects.
Intravaginally: Vaginal discharge.
Serious Adverse Effects (Rare):
Orally: There is concern that L. acidophilus may cause infections in some people.

Dermatologic ...Orally, in one clinical trial, a combination of Lactobacillus acidophilus La-5, Lacticaseibacillus paracasei subsp. paracasei F19, and Bifidobacterium animalis subsp. lacltis BB-12 was associated with two cases of rash, one with itching. However, it is not clear if these adverse effects were due to L. acidophilus, other ingredients, the combination, or if the events were idiosyncratic (90236).

Gastrointestinal ...Orally, taking Lactobacillus acidophilus in combination with other probiotics may cause gastrointestinal side effects including epigastric discomfort (90239), abdominal pain (90239,90291,111785), dyspepsia (90239), flatulence (107497,107520), bloating (107497,111785), diarrhea (111785), vomiting (107537), and burping (90239); however, these events are uncommon.

Genitourinary ...Intravaginally, cream containing Lactobacillus acidophilus has been shown to cause increased vaginal discharge in about 5% of patients, compared to about 1% of patients receiving placebo cream (90237). Vaginal burning was reported by one person using intravaginal L. acidophilus and Limosilactobacillus fermentum in a clinical trial (111781).

Immunologic ...Since Lactobacillus acidophilus preparations contain live and active microorganisms, there is some concern that they might cause pathogenic infection in some patients. L. acidophilus has been isolated in some cases of bacteremia, sepsis, splenic abscess, liver abscess, endocarditis, necrotizing fasciitis, pancreatic necrosis, and meningoencephalitis. Most of these cases are thought to be due to the translocation of bacteria from other locations in the body in which they occur naturally, such as the oral cavity and gastrointestinal tract (107543,111782,111792). L. acidophilus endophthalmitis has been reported rarely (111787,111795). In one case, it was related to intravitreal injections for age-related macular degeneration in a 90-year-old female with an intraocular lens (111787). In another, it occurred following cataract surgery (111795).

General ...Orally, stevia and steviol glycosides appear to be well tolerated. Most minor adverse effects seem to resolve after the first week of use.
Most Common Adverse Effects:
Abdominal bloating, dizziness, headache, myalgia, nausea, and numbness.
Serious Adverse Effects (Rare):
Allergic reactions.

Gastrointestinal ...Orally, stevia and steviol glycosides such as stevioside, can cause gastrointestinal adverse effects such as abdominal fullness and nausea. However, these generally resolve after the first week of use (11809,11810).

Immunologic ...Theoretically, stevia might cause allergic reactions in individuals sensitive to plants in the Asteraceae/Compositae family (11811). Members of this family include ragweed, chrysanthemums, marigolds, daisies, and many other herbs.

Musculoskeletal ...Orally, stevia and steviol glycosides may cause myalgia, but this generally resolves after the first week of use (11809,11810).

Neurologic/CNS ...Orally, stevia and steviol glycosides may cause headache, dizziness, and numbness (11809,11810).

General ...Orally, strawberry is well tolerated when taken in the amounts commonly found in food. When taken in medicinal amounts, strawberry seems to be generally well tolerated (100109,100113,100116,100119). Rarely, strawberry has been reported to cause nausea and allergic reactions, including oral allergy syndrome and skin reactions (100113,100119,103880).
Topically, strawberry can cause contact dermatitis (13637).

Gastrointestinal ...Orally, taking freeze-dried strawberry powder 50 grams daily has been reported to cause nausea in clinical trials (100113,100119).

Immunologic ...Orally, consuming strawberry has been reported to cause allergic reactions, including oral allergy syndrome and skin reactions, in some patients. (103880). Topically, strawberry has caused contact urticaria in one case report (13637). Overall, allergy to strawberry appears to be rare (103880).
