• Colic. It is unclear if oral lactase is beneficial in infants with colic. Details: Preliminary clinical research in infants with colic shows that supplementing human milk or formula with lactase (Crosscare Ltd) for 10 days reduces breath hydrogen levels, but not time spent crying, when compared with placebo. However, approximately 30% of infants in this study were considered to be noncompliant. When only infants considered to be compliant were included in the analysis, time spent crying during the 10-day treatment period was reduced by about 6 hours in the lactase group when compared with placebo (96347). In two other small trials, giving 5 drops of a specific lactase formulation (Colibid, RG Pharmaceutica or Yamoo, Walter Bushnell) to infants aged 0-6 months with colic before each feed, or 4 times a day, for 2-4 weeks significantly reduces crying time and fussing time when compared with placebo (104107,112190). However, measures of crying time were based on subjective parent recall only.
• Prematurity. It is unclear if oral lactase is beneficial in premature patients. Details: Clinical research shows that giving fortified human milk or preterm formula treated with lactase drops (Lactaid, McNeil Consumer Products Company) to preterm infants does not improve weight gain, feeding tolerance, weekly length gain, or gain in head circumference by 36 weeks' gestational age or discharge from the hospital (whichever comes first) when compared with giving untreated milk or formula (96346). More evidence is needed to rate lactase for these uses.

• Celiac disease. Although there has been interest in using oral lipase for celiac disease, there is insufficient reliable information about the clinical effects of lipase for this purpose.
• Dyspepsia. It is unclear if oral lipase is beneficial for improving symptoms of postprandial distress syndrome. Details: A small clinical trial shows that taking a specific acid-resistant lipase (Amano Enzyme USA) 280 mg immediately before a high-fat meal does not reduce postprandial bloating and nausea when compared with placebo in individuals with postprandial distress syndrome (101900).
• Inflammatory bowel disease (IBD). Although there has been interest in using oral lipase for IBD, there is insufficient reliable information about the clinical effects of lipase for this purpose.
• Prematurity. It is unclear if adding a specific form of lipase, recombinant human bile salt-stimulated lipase (rhBSSL), to infant formula improves outcomes in premature infants. Some research suggests a potential increased risk for adverse effects. Details: Human breast milk contains rhBSSL, but it is inactivated when breast milk is pasteurized for donation. Clinical research in infants born before 32 weeks' gestation shows that adding rhBSSL as 8700 units per 100 mL formula or pasteurized breast milk, for 4 weeks does not increase growth velocity, body length, or head circumference over the next 12 months when compared with formula or pasteurized breast milk devoid of lipase. However, the infants who were small for gestational age (SGA), which made up approximately 15% of the study population, grew by an additional 1.9 grams/kg daily on average when compared with placebo (101940). More evidence is needed to rate lipase for these uses.

• Hypercholesterolemia. Most clinical research shows that oral pectin at a dose of 15 grams daily can slightly lower total cholesterol and low-density lipoprotein (LDL) cholesterol levels in patients with hypercholesterolemia. Details: While some small studies in patients with or without hypercholesterolemia suggest that pectin 1-12 grams daily for up to 12 weeks does not reduce lipid levels (2215,2217), other research in patients with hypercholesterolemia shows that taking pectin 15 grams daily for 4 weeks consistently reduces total cholesterol and LDL cholesterol by around 7% to 10% when compared with baseline or placebo (2214,2216,92473). Some forms of pectin might lower cholesterol levels better than others. Pectin with a higher molecular weight and higher degree of esterification appears to be the most effective (92473). A larger clinical study also shows that taking 20 grams of pectin and guar gum, along with small amounts of insoluble fiber, reduces total cholesterol by nearly 8% and LDL cholesterol by nearly 11%, but does not improve high-density lipoprotein (HDL) cholesterol or triglycerides, when compared with placebo (12547).

• Colorectal cancer. Although there has been interest in using oral pectin for the prevention of colorectal cancer, there is insufficient reliable information about the clinical effects of pectin for this purpose.
• Diarrhea. It is unclear if oral pectin is beneficial in children with persistent diarrhea. Details: A small clinical study in children aged 5-12 months in developing nations with persistent diarrhea shows that taking pectin 4 grams/kg reduces the duration of diarrhea and vomiting, and reduces the need for oral rehydration solution and intravenous fluid, when compared with a rice-diet control (12575). Pectin has also been evaluated in combination with other ingredients. One clinical study in children aged 6 months to 6 years with acute diarrhea shows that taking a combination of apple pectin and chamomile (Diarrhoesan, Dr. Loges + Co. GmbH) for up to 5 days reduces the frequency of stools by day 3 by about 1.36-fold when compared with placebo, with improvements maintained through day 5. This combination product was given hourly up to a maximum dose of 50 mL in children 6-12 months of age, 60 mL in children 1-3 years of age, and 80 mL in children 4-6 years of age (19705). It is unclear if these findings are due to pectin, chamomile, or the combination.
• Gastroesophageal reflux disease (GERD). It is unclear if oral pectin is beneficial in children with GERD. Details: A small clinical study in children with GERD and cerebral palsy shows that adding pectin to enteral nutrition in a 1:2 ratio for 4 weeks might reduce some symptoms of GERD. The number of vomiting episodes per week was reduced by 60% and the frequency of coughing/wheezing was reduced by 76% for children given the pectin diet when compared with those given a non-pectin diet (92476).
• Impaired glucose tolerance (Prediabetes). It is unclear if oral pectin is beneficial in patients with impaired glucose tolerance. Details: A small clinical study in middle-aged patients with impaired glucose tolerance or impaired fasting glucose shows that drinking 400 mL of a beverage containing 40 grams/L of sugar beet pectin in two divided doses daily for 12 weeks does not improve fasting or postprandial plasma glucose concentrations or serum lipid levels when compared to baseline (34118).
• Irritable bowel syndrome (IBS). Although there has been interest in using oral pectin for IBS, there is insufficient reliable information about the clinical effects of pectin for this purpose.
• Mercury toxicity. It is unclear if oral pectin is beneficial in patients with mercury toxicity. Details: A small clinical study in children with mercury poisoning shows that taking pectin 2.5 grams daily for 21 days and then 5 grams daily for 39 days increases mercury excretion in the urine, decreases the duration of mercury toxicity, and improves psychological symptoms when compared to baseline (31657). The validity of these findings is limited by the lack of a comparator group.
• Niacin-induced flushing. It is unclear if oral pectin is beneficial for the prevention or management of niacin-induced flushing. Details: A small clinical study shows that taking apple pectin 2 grams 30 minutes prior to taking niacin extended-release 1000 mg reduces the duration of flushing by about 35 minutes when compared with placebo. However, apple pectin does not reduce the incidence of flushing, the time to flush, or the maximum severity of flushing (92477).
• Peptic ulcers. It is unclear if oral pectin is beneficial for the prevention of peptic ulcers. Details: A small clinical study in patients with recently healed duodenal ulcers shows that taking apple pectin 10 grams twice daily for 6 months does not reduce the recurrence of duodenal ulcers when compared with placebo (31697).
• Prostate cancer. It is unclear if oral pectin is beneficial in patients with prostate cancer. Details: Two small clinical studies in patients with prostate cancer show that taking a specific modified citrus pectin product (Pectasol, Econugenics) 4.8 grams three times daily following prostatectomy, radiation, or cryosurgery for up to one year slows disease progression and increases the time to prostate specific antigen (PSA) doubling when compared to baseline (15020,108525). The validity of these findings is limited by the lack of a comparator group.
• Radiation exposure. Although there has been interest in using oral pectin to minimize exposure to environmental radiation, there is insufficient reliable information about the clinical effects of pectin for this purpose. More evidence is needed to rate pectin for these uses.

POSSIBLY EFFECTIVE

• Dyslipidemia. Taking full-fat rice bran, reduced-fat rice bran, or rice bran oil daily appears to modestly reduce lipoprotein (LDL) cholesterol levels. The effects of rice bran on other types of cholesterol are unclear. Details: Clinical research in adults with hypercholesterolemia shows that taking full-fat rice bran 85 grams daily for 6 weeks lowers total cholesterol by 8% and LDL cholesterol by 14% when compared with placebo. Rice bran does not seem to affect triglycerides or high-density lipoprotein (HDL) cholesterol (865). Conversely, a meta-analysis of 8 small clinical studies in patients with hypercholesterolemia, type 2 diabetes, or who have survived colorectal cancer shows that taking rice bran 20 to 100 grams/day does not improve total cholesterol, LDL, HDL, or triglycerides when compared with control (112092). However, the interpretation of these findings is limited by the heterogeneity of patients, dosages, and study designs included in the analysis. The oil from rice bran has also been shown to affect the lipid profile (1354,97524,100481,106591). Multiple meta-analyses of small clinical studies show that taking rice bran oil for 2.5-13 weeks reduces LDL cholesterol levels by 7-8 mg/dL when compared with control. However, rice bran oil does not appear to affect HDL cholesterol levels. Rice bran oil may also modestly lower triglyceride levels; however, results are conflicting between meta-analyses (97524,106591). The validity of these findings is limited by inclusion of low-quality studies and the inclusion of patients without hypercholesterolemia at baseline. The effectiveness of rice bran oil may also depend on the content of gamma-oryzanol. A small clinical study in patients with hyperlipidemia shows that taking rice brain oil 30 mL containing 4000, 8000, and 11000 ppm gamma-oryzanol daily for 4 weeks decreases LDL-C levels when compared with control. The greatest effects occurred in the patients receiving higher gamma-oryzanol content (8000 and 11000 ppm) (100481).

POSSIBLY INEFFECTIVE

• Colorectal cancer. Clinical and population research suggest that consuming dietary cereal fiber, including rice bran, doesn't seem to reduce the risk of colorectal cancer. Details: Clinical research in adults with colorectal adenomas shows that increasing dietary fiber, including rice bran, for up to 4 years does not reduce the risk of recurrent adenomas (4820). Observational research in females has also found that increasing dietary fiber consumption, including rice bran, for up to 16 years is not associated with colorectal cancer risk (4821). However, the validity of these studies is limited by the use of multiple sources of dietary fiber.

• Alcohol use disorder. Although there has been interest in using oral rice bran for alcohol use disorder, there is insufficient reliable information about the clinical effects of rice bran for this purpose.
• Alopecia areata. Although there has been interest in using topical rice bran for alopecia areata, there is insufficient reliable information about the clinical effects of rice bran for this purpose.
• Androgenic alopecia. It is unclear if topical rice bran is beneficial in patients with androgenic alopecia. Details: One small clinical study shows that applying dermal rice bran 5% supercritical CO2 extract (RB-SCE) 4 mL to the scalp twice daily for 16 weeks improves hair density and visual ratings of hair growth in males, but not females, with androgenic alopecia when compared with placebo (97523).
• Athletic performance. Although there has been interest in using oral rice bran for athletic performance, there is insufficient reliable information about the clinical effects of rice bran for this purpose.
• Atopic dermatitis (eczema). It is unclear if topical rice bran is beneficial in patients with atopic dermatitis. Details: Low-quality observational research has found that using a topical rice bran broth bath for 2-5 months reduces skin symptoms in approximately 69% to 94% of patients with atopic dermatitis when compared with baseline. However, the validity of this study is limited by the lack of a comparator group (872).
• Cardiovascular disease (CVD). There is limited evidence on the oral use of rice bran oil in coronary artery disease (CAD). Details: Preliminary clinical research in adult males who recently underwent angioplasty for CAD shows that taking oral rice bran oil 30 grams daily for 8 weeks improves left ventricular ejection fraction by 35% more when compared with taking sunflower oil 30 grams daily. Taking rice bran oil also improves triglyceride and low-density lipoprotein cholesterol levels, but not high-density lipoprotein cholesterol levels, when compared with placebo (106590).
• Diabetes. It is unclear if oral rice bran is beneficial in patients with type 2 diabetes. Details: A small clinical study in adults with type 2 diabetes shows that ingesting stabilized rice bran 20 grams once daily for 12 weeks does not reduce fasting blood glucose, postprandial glucose, or glycated hemoglobin (HbA1c) when compared with ingesting a placebo of 20 grams milled rice flour (97522). However, this study may not have been adequately powered to identify a difference between groups.
• Gastric cancer. Although there has been interest in using oral rice bran to prevent gastric cancer, there is insufficient reliable information about the clinical effects of rice bran for this purpose.
• Halitosis. It is unclear if oral rice bran is beneficial in patients with halitosis. Details: Preliminary clinical research shows that swishing with 15 mL of rice bran oil for 10 minutes and spitting it out, also referred to as "oil pulling", once daily for 14 days, improves halitosis scores when compared with baseline in pregnant adults with halitosis. Rice bran oil was similarly effective to sesame oil or chlorhexidine for reducing halitosis (97526).
• HIV/AIDS. Although there has been interest in using oral rice bran for HIV/AIDS, there is insufficient reliable information about the clinical effects of rice bran for this purpose.
• Hypercalciuria. It is unclear if oral rice bran is beneficial in patients with hypercalciuria. Details: Preliminary observational research in adults with idiopathic hypercalciuria shows that taking oral defatted rice bran 10 grams twice daily for up to 3 years reduces annual kidney stone recurrence by 83% when compared with baseline (876). The validity of this study is limited by the lack of a comparator group.
• Hypertension. Although there has been interest in using oral rice bran for hypertension, there is insufficient reliable information about the clinical effects of rice bran for this purpose.
• Insomnia. It is unclear if oral rice bran is beneficial in patients with insomnia. Details: A small clinical study in patients with disturbed sleep shows that taking a specific rice bran extract (S&D Co.) 1000 mg daily for 2 weeks improves total sleep time by about 20 minutes when compared with placebo. Taking rice bran extract also modestly improves sleep efficiency and sleep quality scores when compared with placebo (103760).
• Obesity. Although there has been interest in using oral rice bran for obesity, there is insufficient reliable information about the clinical effects of rice bran for this purpose. More evidence is needed to rate rice bran for these uses.

DIGOXIN (Lanoxin) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = B Theoretically, pectin might reduce the absorption of digoxin, potentially decreasing its effectiveness.  Details A small clinical study shows that taking digoxin with a kaolin-pectin suspension reduces the absorption of digoxin by about 62% (2212). It is unclear if these effects are due to pectin, kaolin, or the combination.

LOVASTATIN (Mevacor) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, pectin might reduce the absorption of lovastatin, potentially decreasing its effectiveness.  Details Case reports suggest that concomitant use of pectin and lovastatin might reduce the cholesterol-lowering effect of lovastatin, possibly due to reduced intestinal absorption of lovastatin (615).

TETRACYCLINE ANTIBIOTICS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = B Theoretically, pectin might reduce the absorption of tetracycline antibiotics, potentially decreasing their effectiveness.  Details A small clinical study shows that taking tetracycline with bismuth subsalicylate in a kaolin-pectin suspension reduces the absorption of tetracycline by about 34% (2213). It is unclear if these effects are due to pectin, kaolin, bismuth subsalicylate, or the combination.

General ...No adverse effects have been reported in adults. However, a thorough evaluation of safety outcomes has not been conducted.
Serious Adverse Effects (Rare):
Orally: Gastrointestinal adverse effects, such as necrotizing enterocolitis, when recombinant human bile salt-stimulated lipase is used in premature infants.

Gastrointestinal ...Orally, when added to the formula or pasteurized breast milk consumed by premature infants, recombinant human bile salt-stimulated lipase (rhBSSL) can cause gastrointestinal adverse effects, including abdominal distension, flatulence, constipation, colic, abdominal pain, gastroenteritis, vomiting, regurgitation, and rectal bleeding (101940). Premature infants receiving rhBSSL also had a slightly higher rate of necrotizing enterocolitis (NEC) when compared with those receiving placebo. After review by a panel of experts, it was determined that the rate of confirmed or suspected NEC in infants consuming rhBSSL was 3.3%, compared with 0.5% in those receiving placebo. Although this rate of NEC is lower than the historical rate of occurrence in premature infants (11%), a possible increased risk for NEC cannot be ruled out (101940).

General ...Orally, rice bran is generally well tolerated. However, increasing the amount of bran in the diet can cause transient abdominal discomfort, flatulence, and erratic bowel habits.
Most Common Adverse Effects:
Orally: Abdominal discomfort, erratic bowel habits, flatulence.
Topically: Erythema, itching.
Serious Adverse Effects (Rare):
All ROAs: Anaphylactic reactions, including urticaria and angioedema.

Dermatologic ...Topically, rice bran broth baths can cause itching and skin redness (872). In rare cases, rash and itching from rice bran has been associated with contact infestation with Pyemotes tritici, an arthropod commonly called straw itch mite (2284).

Gastrointestinal ...Orally, increasing the amount of bran in the diet can cause erratic bowel habits, flatulence, and abdominal discomfort during the first few weeks (272,106588).

Immunologic ...Orally and topically, rice bran can cause allergic reactions such as urticaria, angioedema, wheezing, itching, and cough (100733,106589). In a case report, a 5-year-old male presented with allergic eczema, urticaria, and cough due to rice bran ingestion (100733). In another case report, a 14-year-old male developed food-dependent, exercise-induced anaphylaxis after consuming 150 grams of rice bran. The 52-kDa and 63-kDa globulin constituents in rice bran have both been implicated as the source of allergic reactions (100732,106589). These constituents are not typically present in cooked, polished rice (106589).

Other ...Be aware that rice bran is a source of inorganic arsenic, which is known to negatively impact long-term health. The amount of inorganic arsenic in rice bran is unknown. However, a small analysis of powder and tablet rice bran products shows that, to exceed the provisional tolerable weekly intake of inorganic arsenic, a person weighing 65 kg would need to consume over 295 grams of rice bran tablets daily or 109 grams of rice bran powder daily. These amounts are higher than the recommended amount of rice bran tablet (3 grams daily) and rice bran powder (10-20 grams daily) listed on the labels of most available supplements (100500).
