POSSIBLY EFFECTIVE

• Constipation. Most clinical research shows that oral inulin modestly improves stool frequency, but may not improve discomfort, in adults and children with constipation. Details: A meta-analysis of clinical research in adults with constipation shows that consuming inulin improves stool frequency by approximately 0.7 stools per week. It also seems to improve stool transit time, consistency, and hardness, but does not reduce pain or bloating (93718). Additional clinical research shows that taking a specific type of inulin (OraftiGR, BENEO GmbH) 12 grams daily in three divided doses for 4 weeks increases stool frequency by approximately one stool per week when compared with a maltodextrin control. Taking inulin also reduces the number of patients experiencing hard and lumpy stools by 13%, but does not improve symptoms of bloating, distension, physical discomfort, or gas (96850). In children aged 2-5 years, one small clinical study shows that taking a specific combination of two inulin products (Orafti P95 oligofructose and Orafti GR inulin, BENEO GmbH), 2 grams twice daily in a dairy liquid for 6 weeks, improves the softness of stools, but not pain with stooling or stool frequency, when compared with a maltodextrin control (96848). Research in older adults is conflicting. One small study shows that taking inulin 20-40 grams daily for 19 days increases the number of stools from 1-2 per week to 8-9 per week (10415). However, other preliminary clinical research in this population shows that taking a specific inulin supplement (Fibruline Instant, Cosucra Groupe Warcoing) 15 grams daily in yogurt or stewed fruit for 4 weeks does not improve bowel symptoms, stool frequency, or stool consistency (93724).
• Diabetes. Short-term use of oral inulin along with antidiabetes drugs may improve glycemic control in some patients with type 2 diabetes; however, the benefits of long-term use are unclear. Details: Two meta-analyses of clinical research in normal weight and obese patients with type 2 diabetes show that taking inulin 0.8-10 grams orally daily for 6-12 weeks reduces glycated hemoglobin (HbA1c) by 0.65% and fasting plasma glucose by 16 mg/dL when compared with control. Taking inulin also improved HOMA-IR, a measure of insulin resistance, when compared with control. Researchers did not evaluate the most effective dose of inulin; however, most studies used 8.4-10 grams daily (103198,105533). In females treated with metformin and glyburide, taking inulin 10 grams daily for 8 weeks reduces fasting blood glucose by 15 mg/dL and HbA1c by 1% when compared with placebo (93719). Population research in adults has also found that high dietary intake of inulin over 8 years of follow up is associated with a 6% lower risk of type 2 diabetes when compared with low dietary intake (110515). Inulin has also been studied in combination with other supplements. Preliminary clinical research in elderly patients with diabetes shows that drinking a milk powder product supplemented with inulin and resistant dextrin 30 grams before breakfast and 15 grams before dinner for 12 weeks decreases fasting plasma glucose by 17 mg/dL, HbA1c by 0.38%, postprandial glucose by 27 mg/dL, body weight by 0.8 kg, and systolic and diastolic blood pressure by 5 mmHg when compared with placebo (99843). Other clinical research in adults with type 2 diabetes shows that taking a specific combination product (Orafti Synergy1, BENEO GmbH), containing 50% inulin and 50% fructo-oligosaccharides, 8 grams orally twice daily for 6 weeks does not reduce body weight or caloric intake or increase satiety scores when compared with placebo (107934).
• Obesity. Oral inulin might modestly improve short-term weight loss. Additional research is needed to determine the long-term effects of inulin on weight loss and weight maintenance in overweight or obese individuals. Details: Some clinical research in overweight and obese females with diabetes shows that taking inulin 10 grams daily for 8 weeks results in weight loss of 2.6 kg, compared with no weight loss in those taking placebo (93719). Preliminary clinical research in overweight or obese patients with prediabetes shows that taking a specific brand of inulin (Orafti Synergy 1, BENEO GmbH) 30 grams orally daily for 6 weeks reduces body weight by 0.4 kg, compared with a 0.4 kg increase in those in the control group (93721). Preliminary clinical research in adults with obesity shows that taking inulin 16 grams orally daily for 3 months moderately reduces body weight and body mass index (BMI) when compared with placebo. However, these effects were most prominent in subjects that also increased physical activity (110514). Additional preliminary clinical research in adults with overweight shows that adding 18 grams of inulin powder to green tea daily increases weight loss when compared with green tea alone. Over six weeks, individuals taking inulin lost 2 kg, compared with no weight loss in those taking green tea. Weight loss was maintained for at least 2 weeks (93726). Clinical trials in children show conflicting results. In children aged 7-12 years, a small clinical study shows that taking a specific oligofructose-enriched inulin product (Orafti Synergy1, BENEO GmbH) 8 grams orally in water before one meal daily for 16 weeks decreases weight gain by 2.4-fold and attenuates an increase in BMI when compared with placebo (96847). However, other preliminary clinical research in children with obesity aged 7-15 years shows that taking inulin extract 13 grams orally daily for 6 months does not reduce body weight or BMI when compared with placebo (110598). However, other clinical research shows that taking inulin orally in combination with other ingredients might not improve weight loss. Combining inulin, chromium picolinate, capsicum, L-phenylalanine, and other nutrients with caloric reduction and exercise doesn't seem to reduce weight in moderately obese patients when compared to caloric reduction and exercise alone (7607). Another preliminary clinical trial shows that taking inulin 10 grams with maltodextrin 10 grams daily for 12 weeks does not reduce body weight or improve body composition when compared with placebo in adults with overweight or obesity following a calorie-restricted diet (103202). Preliminary clinical research in adults with obesity also shows that consuming a seafood-based dietary product fortified with inulin 1.7 grams, fish oil 370 mg (containing eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), and bifidobacterium animalis daily for 12 weeks does not lower body weight, waist circumference, abdominal fat, serum cholesterol levels, or blood pressure when compared with placebo. However, consuming the product modestly improved some markers of insulin resistance (110600).

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Alcohol use disorder. It is unclear if oral inulin is beneficial in patients with alcohol use disorder. Details: Preliminary clinical research in adults with alcohol use disorder who were recently admitted to the hospital shows that taking a specific inulin product (Fibruline, Cosucra) 4-16 grams orally daily for 17 days does not improve liver function tests when compared with placebo. Some liver function tests were also worse in those treated with inulin (110601).
• Antibiotic-associated diarrhea. Oral inulin has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in children aged 6 months to 14 years receiving antibiotics for common infections shows that taking a combination of inulin and fructo-oligosaccharides, up to 5 grams daily depending on age, does not reduce the rate of antibiotic-associated diarrhea (93720).
• Celiac disease. Small clinical studies suggest that patients with celiac disease who take oral inulin may have a lower risk of vitamin and mineral deficiency. Details: Preliminary clinical research in a small number of children and adolescents with vitamin and mineral malabsorption due to celiac disease shows that taking a specific oligofructose-enriched inulin product (Orafti Synergy 1, BENEO GmbH) 10 grams daily for 3 months improves the absorption of vitamin D, vitamin E, and iron, but not vitamin A (99841,99842). Levels of 25-hydroxy vitamin D and vitamin E increased by 42% and 19%, respectively, compared with no significant improvements in those taking placebo (99842). Although taking inulin did not improve serum ferritin levels, it did decrease serum hepcidin concentrations by 61% when compared with baseline, while no significant improvement was reported with placebo. Hepcidin is a regulator of iron homeostasis, and increased levels are associated with iron-deficiency anemia (99841).
• Child growth. Oral inulin has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in healthy, exclusively formula-fed, infants less than 4 months of age shows that supplementing formula with 0.8 grams/dL of a specific combination product (Orafti Synergy1, Beneo-Orafti) containing 50% inulin and 50% fructo-oligosaccharide until 12 months of age does not improve markers of child growth, including body weight, length, and head circumference, when compared with placebo. The combination product was associated with a reduced duration of fever during infectious episodes, but not with a reduction in the number of infections. It is unclear if any potential effects are due to inulin, fructo-oligosaccharide, or the combination (107937).
• Chronic kidney disease (CKD). It is unclear if oral inulin is beneficial in patients with CKD. Details: In adults with CKD, adding inulin 19 grams daily for 6 months to a low-protein diet reduces serum insulin, fasting plasma glucose, total serum cholesterol, triglycerides, and markers of systemic inflammation, while increasing serum high density lipoprotein (HDL) cholesterol, when compared with baseline (105534). However, it is unclear if similar changes occur with a low-protein diet alone, or if the rate of progression of CKD is reduced. Population research in adults has found that high dietary intake of inulin over 8 years of follow up is not associated with a lower risk of CKD when compared with low dietary intake (110515).
• Hypercholesterolemia. It is unclear if oral inulin reduces cholesterol levels in patients with hypercholesterolemia. Details: Research in patients with hypercholesterolemia has shown mixed results, with some studies showing a small decrease and others showing no improvement in serum cholesterol levels (7604,8450,10412,10413,96849). A typical dose of inulin used is 6 grams orally three times daily for up to 6 weeks (10412). A meta-analysis of healthy, dyslipidemic, overweight or diabetic patients shows that inulin reduces levels of low-density lipoprotein (LDL) cholesterol by approximately 5% (96849). Another meta-analysis of randomized clinical trials in the same population shows that taking inulin 1.5-30 grams daily for 2-12 weeks reduces LDL cholesterol levels by 7 mg/dL and increases high-density lipoprotein cholesterol levels by 2 mg/mL when compared with control. However, this meta-analysis also included data from patients treated with fructo-oligosaccharides instead of inulin (107940).
• Hypertension. It is unclear if oral inulin is beneficial in patients with hypertension. Details: Population research in adults has found that high dietary intake of inulin over 8 years of follow up is associated with a 21% lower risk of hypertension when compared with low dietary intake (110515).
• Hypertriglyceridemia. It is unclear if oral inulin is beneficial in patients with hypertriglyceridemia. Details: A meta-analysis of clinical trials in normal and moderately hyperlipidemic patients suggests that taking inulin-type fructans at an approximate average dose of 14 grams daily reduces triglyceride levels by about 15 mg/dL when compared with control (93737). However, other research, including a meta-analysis of healthy, dyslipidemic, overweight or diabetic patients shows that taking inulin 1.5-30 grams daily for 2-12 weeks does not reduce triglyceride levels when compared with control. However, these negative studies are limited by small sample sizes and inclusion of data from patients treated with fructo-oligosaccharides instead of inulin (7604,107940).
• Impaired glucose tolerance (prediabetes). Several small clinical studies suggest that oral inulin is not beneficial in patients with prediabetes. Details: Preliminary clinical research in adults with prediabetes shows that taking inulin 15 grams orally daily for 24 weeks does not improve fasting blood glucose, glycated hemoglobin (HbA1c), or lipid levels when compared with placebo. However, taking inulin modestly improved markers of insulin resistance (107938). Two other, small, clinical trials show that taking specific inulin products (Orafti Synergy 1, BENEO GmbH or Frutafit IQ, Sensus American) 10-30 grams daily for 6 weeks does not improve blood glucose, insulin resistance, glucose homeostasis, or insulin sensitivity when compared with placebo (93721,107936). However, these studies may have been inadequately powered to detect a difference between groups.
• Iron deficiency anemia. Oral inulin has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in young adult females with iron deficiency anemia shows that taking inulin 963 mg/kg and iron supplementation orally daily for 3 months modestly improves serum hemoglobin, hematocrit, and iron levels when compared with a control group consuming iron-fortified flour (110599).
• Menopausal symptoms. It is unclear if oral inulin is beneficial in patients with hypertriglyceridemia. Details: Preliminary clinical research in adults experiencing menopause shows that consuming yogurt enriched with a specific inulin (Frutafit TEX, Sensus Company) 1.5% daily for 6 weeks moderately improves menopausal symptom scores, including depression, anxiety, and vasomotor symptoms, when compared with yogurt alone (107659).
• Nonalcoholic fatty liver disease (NAFLD). Taking oral inulin alone does not seem to improve liver transaminase levels in patients with NAFLD. Details: Preliminary clinical research in patients with NAFLD shows that taking metronidazole 400 mg twice daily for one week plus inulin 4 grams twice daily for 12 weeks reduces levels of alanine aminotransferase and aspartate aminotransferase when compared with placebo. However, when inulin is taken without metronidazole, these measures are not improved (103200).
• Polycystic ovary syndrome (PCOS). It is unclear if oral inulin is beneficial in patients with PCOS. Details: Preliminary clinical research in overweight or obese females with PCOS shows that taking specific products containing inulin (FrutaFit TEX, Sensus American) or inulin and fructo-oligosaccharides (FrutaFit IQ, Sensus American) 10 grams orally once daily for 12 weeks does not reduce systolic or diastolic blood pressure when compared with placebo. However, the validity of this study is limited by the inclusion of subjects with and without hypertension at baseline (107941). More evidence is needed to rate inulin for these uses.

LIKELY INEFFECTIVE

• Alzheimer disease. Lecithin does not improve daily functioning in patients with Alzheimer disease. Details: In patients with Alzheimer disease, taking various types of lecithin, 1.2-45 grams daily for up to 6 months, alone or in combination with various conventional medications, does not improve cognitive function or other measures of disease progression (5149,5151,5152,5156,14817,14823,14825,14837,14838).

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Age-related cognitive decline. It is unclear if oral lecithin can slow age-related cognitive decline. Details: A small clinical crossover study in healthy adults aged 64 years and older shows that taking lecithin 26 grams orally daily, alone or in combination with physostigmine, for 5 weeks does not seem to improve memory when compared with placebo (19204).
• Anxiety. Although there is interest in using oral lecithin for anxiety, there is insufficient reliable information about the clinical effects of lecithin for this condition.
• Atopic dermatitis (eczema). Although there is interest in using oral lecithin for atopic dermatitis, there is insufficient reliable information about the clinical effects of lecithin for this condition.
• Bipolar disorder. It is unclear if oral lecithin is beneficial in patients with bipolar disorder. Details: A clinical study in six patients with mania shows that taking lecithin 10 mg three times daily improves symptoms of delusions, incoherent speech, and hallucinations when compared with placebo (14839).
• Dry skin. Although there is interest in using topical lecithin for dry skin, there is insufficient reliable information about the clinical effects of lecithin for this condition.
• Friedreich ataxia. Small clinical studies suggest that oral lecithin is not beneficial in people with Friedreich ataxia. Details: Preliminary clinical research shows that taking lecithin 25 grams orally daily for 1 month does not have any benefit in people with Friedreich ataxia (59298). Other preliminary clinical research shows that taking lecithin for a longer period of 6 months also does not improve performance (19211).
• Hyperlipidemia. Although lecithin may lower cholesterol in healthy people, it does not seem to improve cholesterol levels in people with hyperlipidemia. Details: Some clinical research shows that taking lecithin 20-30 grams daily for up to 11 months decreases cholesterol in healthy people (5147,14820). However, other clinical research shows that lecithin has no effect on low-density lipoprotein cholesterol or total cholesterol levels in people with hyperlipidemia (5148,14820).
• Parkinson disease. It is unclear if oral lecithin is beneficial in patients with Parkinson disease. Details: Preliminary clinical research in patients with Parkinson disease shows that taking lecithin 32 grams daily for 8 weeks does not improve symptoms when compared with placebo (19212).
• Postoperative pain. It is unclear if oral lecithin is beneficial for reducing postoperative pain. Details: Preliminary clinical research shows that taking lecithin 20 grams prior to surgery increases choline levels, but does not reduce postoperative pain after gynecological surgery, when compared with placebo (91231).
• Tardive dyskinesia. It is unclear if oral lecithin is beneficial in patients with tardive dyskinesia. Details: Two small clinical studies in patients with tardive dyskinesia shows that taking lecithin orally for 2 months, alone or in combination with lithium, does not improve symptoms when compared with placebo (14822,14824).
• TPN-associated hepatic steatosis. It is unclear if oral lecithin is beneficial in patients with hepatic steatosis associated with long-term total parenteral nutrition (TPN). Details: A small clinical study in patients on long-term TPN with low choline levels suggests that taking lecithin 20 grams orally twice daily for 6 weeks reduces the degree of hepatic steatosis, compared with no significant changes in those taking placebo (5140).
• Ulcerative colitis. Oral lecithin has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research shows that taking a disease-specific medical food (Profermin, Nordisk Rebalance) containing lecithin, fermented oats, barley malt, and lactobacillus plantarum, as 250 mL twice daily for 24 weeks, decreases disease activity by over 56% when compared with baseline and leads to remission in 46% of patients with mild-to-moderate ulcerative colitis (91228). Other preliminary clinical research in this population shows that taking Profermin 250 mL twice daily for 8 weeks improves disease activity and remission rate when compared with another medical food (Fresubin Original, Fresenius Kabi) (90271). The effects of lecithin alone are unclear. More evidence is needed to rate lecithin for these uses.
