• Hyperlipidemia. Clinical research suggests that alpha-linolenic acid does not lower lipid levels in adults with hyperlipidemia. Details: A meta-analysis of 20 small clinical trials in patients with hyperlipidemia shows that taking foods or supplements containing alpha-linolenic acid does not reduce lipid levels when compared with control (104256). The findings from this analysis are limited by the heterogeneity of the alpha-linolenic acid supplementation regimens and patient populations.

• Atherosclerosis. Some research suggests that increasing dietary alpha-linolenic acid intake may decrease atherosclerosis. Details: Epidemiological research in White adults has found that high dietary intake of linolenic acid is associated with reduced calcified atherosclerotic plaques in the coronary arteries. Most dietary linolenic acid is alpha-linolenic acid (only a small fraction is gamma-linolenic acid). For every gram of linolenic acid consumed, risk of coronary artery calcification appears to decrease by 62% (12990). The effects of linolenic acid intake in other populations are unclear.
• Atopic dermatitis (eczema). Although there is interest in using oral alpha-linolenic acid (ALA) for atopic dermatitis, there is insufficient reliable information about the clinical effects of ALA for this condition.
• Attention deficit-hyperactivity disorder (ADHD). It is unclear if alpha-linolenic acid is beneficial in patients with ADHD. Details: Small clinical trials show that taking alpha-linolenic acid does not improve symptoms of previously untreated ADHD in children aged 6-16 years. Taking alpha-linolenic acid 1 gram daily for 8 weeks, or taking a combination of alpha-linolenic acid 60 mg, linoleic acid 240 mg, mineral oil 95 mg, and alpha-tocopherol 5 mg twice daily for 7 weeks does not affect ADHD symptom scores when compared with placebo (100660,100661). However, these studies might have been inadequately powered to detect a difference between groups.
• Cancer. It is unclear if increased dietary intake of alpha-linolenic acid affects mortality in patients with cancer. Details: A large meta-analysis of prospective, observational studies has found that high dietary intake of alpha-linolenic acid is associated with a 6% increased risk of mortality from cancer when compared with low dietary intake of alpha-linolenic acid (106661).
• Cardiovascular disease (CVD). Population research has found that increased dietary intake of alpha-linolenic acid may have some benefit for CVD, but results from clinical research are generally less positive. Details: A large meta-analysis of prospective, observational studies has found that high dietary intake of alpha-linolenic acid is associated with an 8% or 11% reduced risk of mortality from CVD or coronary heart disease (CHD), respectively, when compared with low dietary intake of alpha-linolenic acid. A dose-response analysis and meta-analysis show that a 1-gram increase in daily dietary intake is associated with a 5% reduction in CVD mortality (106661,107741). Other population research has found that consumption of 1-2 grams of dietary alpha-linolenic acid daily is associated with a reduced risk of a first myocardial infarction (MI) by as much as 59% in both males and females (7152,7156). The risk of fatal ischemic heart disease is reduced by 65% in females (7153). In patients who have had a previous MI, following a Mediterranean diet rich in alpha-linolenic acid (1.2-1.6 grams daily) and low in saturated fat and cholesterol for 27 months appears to reduce the risk for a second MI by 73% and the risk for death from any cause by 70% when compared to the standard postinfarction diet (7150). Overall, increasing dietary intake of alpha-linolenic acid by 1-1.2 grams daily appears to reduce the risk of fatal coronary heart disease by 20% in people with no history of heart disease and by 20% or more in people with existing heart disease (12978,91403). However, clinical research has not supported these findings. A meta-analysis of a small number of low to moderate quality clinical studies shows that higher intake of alpha-linolenic acid has little to no benefit for primary prevention of CVD, and does not reduce all-cause mortality, CVD mortality, or CHD events. Any reductions in CVD mortality, arrhythmias, or CHD events in individual trials are very small (103955). This may be due in part to the difficulty in separating the effects of alpha-linolenic acid from those of other dietary, lifestyle, or drug interventions (12917). Some research suggests alpha-linolenic acid has a greater effect on coronary heart disease when intake of fish oils is low (12989).
• Chronic obstructive pulmonary disease (COPD). Although there is interest in using oral alpha-linolenic acid (ALA) for COPD, there is insufficient reliable information about the clinical effects of ALA for this condition.
• Cognitive function. It is unclear if oral alpha-linolenic acid improves cognitive function in healthy adults.
• Crohn disease. Although there is interest in using oral alpha-linolenic acid (ALA) for Crohn disease, there is insufficient reliable information about the clinical effects of ALA for this condition.
• Crohn disease. Although there is interest in using oral alpha-linolenic acid (ALA) for Crohn disease, there is insufficient reliable information about the clinical effects of ALA for this condition.
• Depression. It is unclear if oral alpha-linolenic acid is beneficial in patients with depression. Details: Clinical research in patients aged 60-80 years who have had a myocardial infarction shows that consuming margarine containing alpha-linolenic acid 2 grams daily for 40 months does not reduce symptoms of depression when compared with placebo margarine (104978).
• Diabetes. It is unclear if oral alpha-linolenic acid is beneficial in patients with diabetes. Details: Epidemiological research involving overweight and obese individuals has found that eating at least 1.69 grams alpha-linolenic acid daily is associated with a 45% to 47% reduced risk of developing type 2 diabetes when compared with eating only 0.73 grams daily. However, higher intake of alpha-linolenic acid does not appear to be associated with a reduced risk of diabetes in people who are not overweight (101025). In patients with diabetes, epidemiological research shows that lower intake of alpha-linolenic acid is associated with an increased risk of diabetic nephropathy (101024). However, a meta-analysis of clinical research in adults with diabetes who are stable on oral antidiabetic medications shows that adding alpha-linolenic acid 1.5-7.4 grams daily, in the form of flaxseed oil, walnuts, or chia seeds, to a regular diet for 2-12 months does not improve glycemic control when compared with placebo (98002).
• Influenza. Although there is interest in using oral alpha-linolenic acid (ALA) for influenza, there is insufficient reliable information about the clinical effects of ALA for this condition.
• Hypertension. Some research suggests that increasing dietary alpha-linolenic acid may decrease the risk of hypertension. Details: Epidemiological research has found that high dietary intake of linolenic acid is associated with a reduced risk of hypertension in White adults. Most dietary linolenic acid is alpha-linolenic acid (only a small fraction is gamma-linolenic acid). Eating a diet high in linolenic acid seems to reduce the risk of hypertension by about 33% (12991). The effects of linolenic acid intake in other populations are unclear.
• Kidney transplant. Observational research suggests that alpha-linolenic acid is not beneficial after a kidney transplant, and may actually increase the risk of mortality. Details: Epidemiological research has found that dietary intake of alpha-linolenic acid is not associated with improved graft function in kidney transplant. However, kidney transplant recipients in the highest tertile of alpha-linolenic acid intake appear to have a 2.2-fold increased risk of death from any cause when compared with those in the lowest tertile of dietary intake (98003). It is not clear whether this difference is specifically due to alpha-linolenic acid intake or to total fat intake.
• Migraine headache. Although there is interest in using oral alpha-linolenic acid (ALA) for migraine headache, there is insufficient reliable information about the clinical effects of ALA for this condition.
• Multiple sclerosis. Although there is interest in using oral alpha-linolenic acid (ALA) for MS, there is insufficient reliable information about the clinical effects of ALA for this condition.
• Overall mortality. It is unclear if increased dietary intake of alpha-linolenic acid affects all-cause mortality. Details: A large meta-analysis of prospective, observational studies has found that high dietary intake of alpha-linolenic acid is associated with a 10% reduced risk of all-cause mortality when compared with low dietary intake of alpha-linolenic acid. A dose-response analysis shows that a 1-gram increase in daily dietary intake is associated with a 5% reduction in overall mortality (106661). However, a meta-analysis of 250,000 individuals did not find an association between dietary alpha-linolenic acid intake and all-cause mortality (107741). The validity of this finding is limited by the use of dietary surveys to assess intake and the heterogeneity of the included studies.
• Prostate cancer. There is contradictory evidence about the role of alpha-linolenic acid in prostate cancer. Details: Some epidemiologic research suggests that high dietary intake of alpha-linolenic acid is associated with an increased risk for prostate cancer (1337,2558,7823,7147,12978). Other research suggests high intake or serum levels of alpha-linolenic acid is not associated with increased levels of prostate specific antigen (PSA) or the overall risk of prostate cancer (12961,15736,91402). However, it might increase the risk of advanced prostate cancer (12961). The best evidence to date, which comes from a meta-analysis of five prospective population studies, suggests that increasing intake of alpha-linolenic acid by 0.5 grams daily is associated with a modest 1% reduction in the risk of prostate cancer. However, this analysis is dominated by a single study. A meta-analysis of results from nine prospective population studies suggests that a 0.1% increase in blood levels of alpha-linolenic acid is not associated with prostate cancer risk (90677). Reasons for the discrepancies are not entirely clear, but the source of alpha-linolenic acid appears to be important. Alpha-linolenic acid from dairy and meat sources has been positively associated with prostate cancer. Alpha-linolenic acid from plant sources, such as flaxseed, may not affect prostate cancer risk (12909).
• Pneumonia. It is unclear if dietary alpha-linolenic acid reduces the risk for pneumonia. Details: Epidemiological research has found that increasing dietary alpha-linolenic acid consumption is associated with a reduced risk of community-acquired pneumonia (13760).
• Psoriasis. Although there is interest in using oral alpha-linolenic acid (ALA) for psoriasis, there is insufficient reliable information about the clinical effects of ALA for this condition.
• Respiratory tract infections. It is unclear if oral alpha-linolenic acid is beneficial for reducing the incidence of respiratory tract infections in children. Details: Preliminary clinical research in children aged 3-4 years shows that taking alpha-linolenic acid 855 mg, in combination with linoleic acid 596 mg daily from November through February in 2 consecutive years, might reduce the number of recurrent respiratory infections when compared with placebo (10785).
• Rheumatoid arthritis (RA). It is unclear if oral alpha-linolenic acid is beneficial in patients with RA. Details: Preliminary clinical research shows that taking an alpha-linolenic acid-rich oil (flaxseed oil) for 3 months does not improve symptoms or laboratory parameters of RA when compared with baseline or with a linoleic acid-rich oil (safflower oil) (5898).
• Systemic lupus erythematosus (SLE). Although there is interest in using oral alpha-linolenic acid (ALA) for SLE, there is insufficient reliable information about the clinical effects of ALA for this condition.
• Ulcerative colitis. Although there is interest in using oral alpha-linolenic acid (ALA) for ulcerative colitis, there is insufficient reliable information about the clinical effects of ALA for this condition. More evidence is needed to rate alpha-linolenic acid for these uses.

• Hypercholesterolemia. Preliminary clinical research shows that eating muffins made with amaranth flour or taking oral doses of amaranth oil 3-18 mL daily while following a reduced fat diet for 3-4 weeks does not reduce serum cholesterol levels more than the reduced fat diet alone (6188,31069). Similarly, two clinical trials in overweight and obese adults show that taking amaranth oil 20 mL daily for 3 weeks does not decrease low-density lipoprotein (LDL) cholesterol or triglyceride levels or increase high-density lipoprotein (HDL) cholesterol levels when compared with either rapeseed oil 20 mL daily or no intervention (104834,104837). In one of these trials, amaranth oil 20 mL increased LDL levels when compared to baseline (104834).

• Iron deficiency anemia. Preliminary clinical research in children shows that consuming 150 grams of bread made with 70% amaranth grain, providing approximately 22.3 mg iron, for 6 months decreases the prevalence of anemia by 61% and increases hemoglobin levels by 8% when compared with consuming bread containing 100% maize grain. The amaranth used in this study was processed to reduce phytic acid content in order to improve iron absorption (104835).
• Peptic ulcers. Preliminary clinical research shows that taking amaranth oil from Amaranthus cruentus seeds 1 mL daily for 27 days immediately following standard treatment with lansoprazole, amoxicillin, and clarithromycin for 7 days does not improve clinical outcomes with Helicobacter pylori-associated peptic ulcers more than standard treatment alone (99235). More evidence is needed to rate amaranth for these uses.

• 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.

• Benign prostatic hyperplasia (BPH). Taking oral pumpkin seed or pumpkin seed oil may improve symptoms of BPH. Details: One study in patients with BPH shows that taking pumpkin seed 5 grams twice daily for 12 months may be more effective for controlling symptoms than pumpkin seed extract 1000 mg twice daily (92383). A specific pumpkin seed extract (Prosta Pink Forte) 1-2 capsules daily for 12 weeks has also been used (11231). Some preliminary clinical research also suggests that taking pumpkin seed oil (Prostafit, EuRho Vital) two tablets daily for 6 months may be as effective as the medication prazosin (92382). Pumpkin seed oil has also been compared with tamsulosin. A clinical study comparing pumpkin seed oil 360 mg twice daily to tamsulosin 0.4 mg once nightly for 3 months shows that both treatment groups report improvements in BPH symptoms and quality of life when compared with baseline, although improvement appears greater in the tamsulosin group, specifically when measured at 1 month and 3 months. In the pumpkin seed oil group, adverse effects were reported in 0% of patients, compared with 15% of patients taking tamsulosin (107842). The validity of this study is limited due to the short duration of treatment. Pumpkin seed oil or extracts have also been studied in combination with saw palmetto (6777), with saw palmetto, nettle root, and lemon extracts plus beta carotene (5093), and with saw palmetto, small flowered willow herb, lycopene, and pygeum (92379).

• Androgenic alopecia. Oral pumpkin seed oil might improve hair regrowth in males with mild to moderate hair loss. Details: Clinical research in males with mild to moderate hair loss shows that taking pumpkin seed oil (Octa Sabal Plus, Dreamplus Co. Ltd.) 400 mg daily in divided doses for 24 weeks increases hair count by 30% when compared with placebo. Self-rated improvement and satisfaction scores were 62% and 52% with pumpkin seed oil and placebo, respectively (92378). Clinical research in patients with female pattern hair loss shows that applying 1 mL of pumpkin seed oil to the scalp daily for 30 days improves hair regrowth similarly to minoxidil 5% foam, 1 mL daily (104974).
• Interstitial cystitis. Although there is interest in using oral pumpkin for interstitial cystitis, there is insufficient reliable information about the clinical effects of pumpkin for this condition.
• Intestinal parasite infection. Although there is interest in using oral pumpkin for intestinal parasite infection, there is insufficient reliable information about the clinical effects of pumpkin for this condition.
• Overactive bladder. Oral pumpkin seed oil has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in females with overactive bladder shows that taking a specific combination product (Granu Fink femina, Omega Pharma) containing pumpkin seed oil 227 mg, sweet sumac bark extract 56 mg, and hops cone extract 18 mg three times daily for 12 weeks decreases the frequency of urination and leakage and improves quality of life when compared to baseline (103253). The validity of these findings is limited by the lack of a control group. Additionally, it is unclear if these findings are due to pumpkin seed oil, other ingredients, or the combination.
• Urinary tract infections (UTIs). Although there is interest in using oral pumpkin for UTIs, there is insufficient reliable information about the clinical effects of pumpkin for this condition. More evidence is needed to rate pumpkin for these uses.

• HIV/AIDS. Preliminary clinical research in HIV patients using antiretroviral therapy shows that taking a specific product containing sorghum extract and other ingredients (Jobelyn, Health Forever Product Ltd.) orally twice daily for 12 weeks improves CD4+ T cell count when compared with antiretroviral therapy alone. Hemoglobin levels were increased compared with baseline in patients ineligible for antiretrovirals (97674).
• Iron deficiency anemia. Preliminary clinical research shows that taking a specific product containing sorghum extract and other ingredients (Jobelyn, Health Forever Product Ltd.) orally once daily for 3 weeks does not improve red blood cell indices in patients with anemia who were also taking iron 600 mg daily and folic acid 5 mg daily (97675).
• Obesity. Preliminary clinical research in overweight and obese men shows that eating extruded sorghum cereal 40 grams each morning along with a calorie restricted diet for 8 weeks reduces body fat by around 2%, but does not appear to improve body weight, body mass index, or waist circumference, when compared with extruded wheat cereal plus calorie restriction (103898). More evidence is needed to sorghum for these uses.

• Coronary heart disease (CHD). The U.S. Food and Drug Administration (FDA) allows a qualified health claim stating that using high-oleic acid sunflower oil as a replacement for other dietary fats and oils higher in saturated fat may reduce the risk of CHD. Details: A meta-analysis of clinical studies shows that replacing 7.5% of energy from partially hydrogenated vegetable oils with high-oleic acid sunflower oil can reduce CHD risk by about 9% to 19%. Furthermore, analysis of results from observational studies found that replacing partially hydrogenated oil with high-oleic acid sunflower oil is associated with a 16% to 35% reduction in the risk of CHD events (95745). The FDA allows for a qualified health claim that replacing dietary fats and oils higher in saturated fat with high-oleic acid sunflower oil may reduce the risk of CHD. To achieve this benefit, the use of high-oleic acid sunflower oil should not increase total daily energy intake. The suggested daily dietary intake is about 20 grams (1.5 tbsp) of high-oleic sunflower oil in place of other fats and oils (98563). Sunflower oil that contains high amounts of linoleic acid rather than oleic acid does not appear to improve cholesterol levels or reduce the risk of cardiovascular events in patients with CHD (96205).
• Hypercholesterolemia. Consuming sunflower oil in the diet may reduce low-density lipoprotein (LDL) cholesterol levels in some patients. Details: There is evidence that using sunflower oil in the diet as 45-50 grams daily for up to 12 weeks is more effective than olive oil for decreasing LDL cholesterol and apolipoprotein B levels in healthy individuals (9780). Also, clinical research in patients with mild hyperlipidemia or moderate hypercholesterolemia shows that consuming specific brands of mid-oleic acid (NuSun) or high-oleic acid (Sunola, Meadow Lea Foods) sunflower oils as 15% to 20% of dietary calories for up to 5 weeks is more effective than olive oil or saturated fat for decreasing total cholesterol, LDL cholesterol, and apolipoprotein B levels (76697,76698). Also, consuming a high-oleic sunflower oil-rich diet for 3 weeks decreases total cholesterol levels to a greater extent than diets enriched with palm oil or medium-chain triglycerides in patients with mild hypercholesterolemia (67569). Other preliminary clinical research in patients with moderate hypercholesterolemia shows that consuming a diet rich in sunflower oil for 3 weeks decreases total cholesterol and LDL cholesterol levels when compared with baseline. However, levels of high-density lipoprotein (HDL) cholesterol appear to be lowered as well (76714). Despite these beneficial effects, sunflower oil might be less effective than some other dietary oils. Taking sunflower oil for 3 months appears to be less effective than rice bran oil for lowering cholesterol in patients with hypercholesterolemia (76699). Also, while consuming sunflower oil 45 grams daily, as part of the diet and as a supplement, for 12 weeks reduces levels of total cholesterol and LDL cholesterol when compared to baseline, it appears to be less effective at reducing total cholesterol levels than flaxseed oil in certain patients at risk for atherosclerosis (76696). In addition, taking sunflower oil 15.1 grams daily for 4 months does not appear to reduce levels of total or LDL cholesterol in patients with peripheral vascular disease (76691).

POSSIBLY INEFFECTIVE

• Hypertension. Oral sunflower oil does not seem to lower blood pressure. Details: Preliminary clinical research in adults with hypertension shows that taking sunflower oil 30-40 grams daily for one year is less effective than extra-virgin olive oil for reducing blood pressure (5091). Also, clinical research in elderly adults with hypertension shows that taking 60 grams of sunflower oil daily for 4 weeks is less effective than virgin olive oil for reducing systolic blood pressure (76692).

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Atherosclerosis. It is unclear if oral sunflower oil is beneficial for atherosclerosis; some clinical research suggests that it may provide less benefit than other dietary oils. Details: Some preliminary clinical research in individuals with overweight and obesity shows that taking sunflower oil 30 mL (about 27 grams) daily for 90 days decreases carotid intima-media thickness (CIMT) by 3.5% when compared to baseline, but not when compared with olive oil or flaxseed oil. Sunflower oil also improves flow-mediated vasodilation by 73% when compared to baseline, compared with no improvement in those taking flaxseed oil or olive oil (99303). Other preliminary clinical research in individuals waiting for carotid endarterectomy shows that taking sunflower oil 6 grams daily for up to 189 days is less effective than the same dose of fish oil, and equivalent to control oil, for improving the status of atherosclerotic plaques (76688).
• Atopic dermatitis (eczema). Although there is interest in using topical sunflower oil for atopic dermatitis, there is insufficient reliable information about the clinical effects of sunflower oil for this condition.
• Child growth. It is unclear if topical sunflower oil is beneficial for early child growth. Details: A large preliminary clinical trial in newborn infants in India shows that exclusive topical application of 10 mL of high-linoleic acid sunflower oil, an average of 2.7 times daily for about one month, increases weight gain by 1.3 gram/kg daily when compared with a control group exclusively given traditional vigorous massage with mustard oil an average of 2.4 times daily. The increase in weight gain was highest for infants weighing less than 1500-2000 grams at birth (108141). However, it is unclear if any beneficial effects are due to the sunflower oil, the massage, their combination, or the lack of mustard oil.
• Dry mouth. It is unclear if rinsing the mouth with sunflower oil is beneficial for dry mouth. Details: Preliminary clinical research in adults with moderate dry mouth associated with medication use shows that using a sunflower oil mouth rinse and gargling for 5-8 minutes before spitting it out twice daily for 7 days improves dry mouth scores by 23% when compared to baseline. Sunflower oil also improves the ability to swallow and sleep with dry mouth, but not other dry mouth symptoms or saliva flow rate, when compared with control (105523). This study may have been inadequately powered to detect a difference between groups.
• Dry skin. It is unclear if topical sunflower oil is beneficial for dry skin in infants. Details: Preliminary clinical research in full-term, newborn infants shows that topical application of 4 drops of sunflower oil to each of three parts of the body twice daily for 4 weeks improves skin hydration, but not skin barrier function or the presence of redness or rash, when compared with not using topical oil. Furthermore, use of sunflower oil may impede the normal development of skin barrier function that occurs during the first four weeks of life (96144).
• Fetal and premature infant mortality. It is unclear if topical sunflower oil is beneficial for preventing early mortality in premature infants. Details: A large clinical trial in newborn infants in India shows that exclusive topical application of 10 mL of high-linoleic acid sunflower oil, an average of 2.7 times daily for about one month, reduces infant mortality by 58% when compared to a control group exclusively given traditional vigorous massage with mustard oil an average of 2.4 times daily. A subgroup analysis of premature infants also shows a 52% reduction in mortality with the use of high-linoleic acid sunflower oil when compared with control (108143). However, it is unclear if any beneficial effects are due to the sunflower oil, the massage, their combination, or the lack of mustard oil.
• Prematurity. Small to moderate-sized clinical studies suggest that topical sunflower oil might increase body weight, reduce length of hospital stay, and improve skin hydration and skin integrity in preterm neonates. Details: Preliminary clinical research in preterm infants with low birth weight shows that massaging for 5-10 minutes using sunflower oil 10 mL/kg three times daily for 2 weeks increases weight gain by approximately 35% over 2 months when compared with massage using no oil. Sunflower oil massage does not appear to increase length or head circumference (96145). A small clinical study in premature infants in the intensive care unit (ICU) shows that a similar massage with sunflower oil three times daily for 5 days shortens ICU stay by about 5 days when compared with no massage. Furthermore, over the ICU stay, infants in the sunflower oil massage group gained an average of 15 grams, whereas infants in the control group experienced weight loss (98479). The effect of sunflower oil on skin hydration and integrity in preterm infants has also been assessed. A clinical trial of 90 preterm infants in a Turkish neonatal ICU shows that whole body skin treatment (not massage) with either sunflower oil or almond oil 4 mL/kg four times daily for 5 days improves measures of skin hydration and skin integrity when compared with control infants that did not receive oil treatment. The sunflower and almond oil treatments are equally effective (105524). Another clinical study in 90 infants (42% preterm) in a Turkish neonatal ICU shows that whole body skin treatment (not massage) with sunflower oil or liquid Vaseline 3-4 mL for preterm and 5-6 mL for full-term infants daily for 16 days improves measures of skin integrity when compared with control infants that did not receive any oil treatment. Skin integrity scores were better in the sunflower oil group than liquid Vaseline at some time points (111726).
• Psoriasis. Although there is interest in using topical sunflower oil for psoriasis, there is insufficient reliable information about the clinical effects of sunflower oil for this condition.
• Rheumatoid arthritis (RA). Although there is interest in using oral sunflower oil for RA, there is insufficient reliable information about the clinical effects of sunflower oil for this condition.
• Tinea pedis. It is unclear if topical sunflower oil is beneficial for tinea pedis. Details: Preliminary clinical research shows that topical application of a specific brand of ozonized sunflower oil (Oleozon) twice daily for 6 weeks is as effective as ketoconazole for curing athlete's foot (76687). More evidence is needed to rate sunflower oil for these uses.

General ...Orally, alpha-linolenic acid from dietary sources is well tolerated when used in the diet as a replacement for other sources of fat, such as saturated fats.
Serious Adverse Effects (Rare):
Orally: There is some concern that high dietary intake of alpha-linolenic acid might increase the risk for prostate cancer, although research is conflicting.

Oncologic ...Epidemiologic research suggests that high dietary intake of alpha-linolenic acid might increase risk for prostate cancer (1337,2558,7823,7147,12978). Other research suggests high intake or serum levels of alpha-linolenic acid does not increase the overall risk of prostate cancer (12961,15736); however, it might increase the risk of advanced prostate cancer (12961). Association with prostate cancer appears to depend on the sources of alpha-linolenic acid. Dairy and meat sources has been positively associated with prostate cancer, whereas plant sources, such as flaxseed, don't seem to affect prostate cancer risk (12909). According to a clinical trial, intake of alpha-linolenic acid does not appear to increase levels of prostate specific antigen (PSA) (91402). Also, longer-chain omega-3 fatty acids in fish oils are associated with a decreased risk of total and advanced prostate cancer (12961).

Other ...Alpha-linolenic acid is a type of fat, containing 9 kilocalories/gram, and may result in weight gain if consumed in excess. Patients should be advised that it's best to substitute alpha-linolenic acid in the diet for other sources of fat, such as saturated fats.

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, pumpkin products are generally well tolerated.
Most Common Adverse Effects:
Orally: Abdominal discomfort, diarrhea, nausea, and vomiting.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis.

Dermatologic ...There are two case reports of adult females developing substantial transient hair loss 1-3 weeks after consumption of a meal containing either bitter-tasting pumpkin or undefined squash. This adverse effect was attributed to a high concentration of cucurbitacin, which is commonly found in wild pumpkins (104535).

Gastrointestinal ...Orally, pumpkin seed oil has been reported to cause mild abdominal discomfort in clinical trials (5093,92378). There are also two case reports of adults developing severe nausea, vomiting, and diarrhea following consumption of a meal containing either bitter-tasting pumpkin or undefined squash. These adverse effects were attributed to a high concentration of cucurbitacin, which is commonly found in wild pumpkins (104535).

Immunologic ...Orally, pumpkin seed oil and pumpkin pulp have been reported to cause anaphylactic reactions in children and adults. A case review highlights 4 cases of anaphylaxis in children (3 from pumpkin pulp, 1 from pumpkin seeds), and 7 cases in adults (1 from pumpkin flesh, 6 from pumpkin seeds). Symptoms of anaphylaxis include urticaria, angioedema of the lips or face, dyspnea, dysphagia, and oropharyngeal itching and swelling. A case report describes a 2-year-old male presenting with urticaria, swollen lips, and increased dyspnea 10 minutes after ingesting pumpkin seeds. The patient was found to have elevated allergen-specific immunoglobulin E (IgE) and a positive skin-prick test for pumpkin seeds. Symptoms resolved after treatment with epinephrine, systemic glucocorticoids, salbuterol, and antihistamines (107843).
There may also be concern for allergic reaction due to inhalation or topical exposure. One case report describes an 8-year-old child developing anaphylaxis while carving a pumpkin; another highlights that inhalation of pumpkin seed flour may have potentiated anaphylaxis in 3 individuals following the ingestion of pumpkin seeds (107843). Further research is necessary to assess the relationship between anaphylaxis and route of administration.
