• Coronary heart disease (CHD). Consuming products containing at least 3.6 grams of soluble fiber, including beta-glucans, per day may reduce the risk of CHD when consumed as part of a diet low in saturated fat and cholesterol. Details: Clinical research shows that a diet containing foods high in beta-glucans, such as oats and barley, reduces the risk of heart disease (2737,4960,4962,4963,4964,4965,4966,4967,4968). In 1993, the FDA approved a health claim stating that consuming products containing at least 3 grams of beta-glucans per day, as part of a diet low in saturated fat and cholesterol, may reduce the risk of CHD (102336). However, clinical studies show that at least 3.6 grams of soluble fiber daily is needed to reduce the risk of CHD (5786,5787,5788,5794,5795,5796).
• Dyslipidemia. Oral beta-glucans modestly reduces low-density lipoprotein (LDL) cholesterol levels. Details: Although some research disagrees, most clinical research shows that taking barley- or oat-derived beta-glucans 3-10 grams daily for up to 12 weeks or yeast-derived beta-glucans 7.5 grams twice daily for 7-8 weeks can reduce LDL and total cholesterol levels when used for up to 12 weeks (5790,5796,7272,17129,34700,34727,34729,34765,34766,34811)(34812,34876). Meta-analyses of available clinical research on oat-derived beta-glucans show that taking at least 3 grams daily reduces LDL cholesterol by around 4-10 mg/dL and total cholesterol by 4-12 mg/dL but does not affect high-density lipoprotein (HDL) cholesterol or triglyceride levels when compared with control diets (92660,97987,112225). Consuming oat-derived beta-glucans also reduces apolipoprotein B (apoB) levels by 0.54 mg/dL when compared with control diets (97987). The effects of oat-derived beta-glucans on cholesterol levels appear to be greater in patients with diabetes and those with higher LDL cholesterol levels (92660,97987). A meta-analysis of available clinical research on barley-derived beta-glucans shows that consuming an average of 6.5-7 grams of beta-glucans daily as part of the diet reduces LDL cholesterol levels by 4.5 mg/dL, total cholesterol levels by 5.6 mg/dL, and apoB levels by 0.54 mg/dL when compared with control diets (98204). The form of beta-glucans used may alter the effect of beta-glucans on cholesterol levels. Some research shows that barley that is highly enriched (75% by weight) with beta-glucans does not significantly affect cholesterol levels. This lack of effect seems to be the result of processing the barley into a highly enriched beta-glucans product (10166). Other clinical research also shows that the processing of beta-glucans products or the food matrix used to make these products might reduce beta-glucans molecular weight and/or solubility and therefore decrease its ability to lower cholesterol levels (10145,34800,34819).

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Aging. Although there is interest in using oral or topical beta-glucans for aging, there is insufficient reliable information about the clinical effects of beta-glucans for this purpose.
• Allergic rhinitis (hay fever). It is unclear if oral beta-glucans are beneficial for reducing symptoms of allergic rhinitis. Details: A small clinical trial in patients allergic to ragweed shows that taking specific yeast-derived beta-glucans (Wellmune WGP) 250 mg daily for 4 weeks decreases the number of allergy symptoms by 28% and the severity of allergy symptoms by 52% when compared with placebo (34859).
• Atopic dermatitis (eczema). It is unclear if topical beta-glucans are beneficial for atopic dermatitis. Details: Preliminary clinical research in children and adults with atopic dermatitis shows that applying a specific cream (Imunoglukan P4H, PLEURAN s.r.o.) containing beta-glucans 0.25% 2-3 times daily for 6 months modestly reduces pruritus, intensity of flares, and overall disease severity when compared with the application of a standard emollient (98201).
• Benign prostatic hyperplasia (BPH). Although there is interest in using oral beta-glucans for BPH, there is insufficient reliable information about the clinical effects of beta-glucans for this purpose.
• Cancer. Although there is interest in using oral beta-glucans for cancer, there is insufficient reliable information about the clinical effects of beta-glucans for this condition.
• Canker sores. It is unclear if oral beta-glucans are beneficial for canker sores. Details: Preliminary clinical research shows that taking beta-glucans 10 mg twice daily for 20 days reduces ulcer severity in patients with recurrent aphthous stomatitis when compared with placebo (34763).
• Chronic fatigue syndrome (CFS). Although there is interest in using oral beta-glucans for CFS, there is insufficient reliable information about the clinical effects of beta-glucans for this condition.
• Critical illness (trauma). It is unclear if oral beta-glucans are beneficial for patients with critical illness. Details: Preliminary clinical research shows that taking oat-derived beta-glucans 3 grams daily as part of enteral feeds does not reduce the length of hospital stay, mortality rate, or infection rate when compared with placebo in patients with trauma. However, the length of time on mechanical ventilation was approximately 47% shorter when compared with placebo (100186).
• Diabetes. Small clinical studies in children and adults with type 1 diabetes suggest that beta-glucans do not improve blood glucose levels. It is unclear if oral beta-glucans are beneficial for patients with type 2 diabetes. Details: Some preliminary clinical research in adults with type 2 diabetes shows that consuming oat-derived beta-glucans 3 grams daily in bread for 3 weeks improves insulin resistance and cholesterol levels when compared with control bread (34765). Other preliminary clinical research in patients with type 2 diabetes shows that consuming bread containing oat-derived beta-glucans in a ratio of 7.6 grams per 100 grams of starch daily for 6 months reduces postprandial glucose levels and glycated hemoglobin (HbA1c) when compared with control bread (97986). Additionally, some clinical research shows that replacing a half serving of white rice with beta-glucans-containing barley attenuates increases in postprandial glucose and insulin levels when compared with a full serving of white rice in patients with type 2 diabetes (103887). However, oat-derived beta-glucans 3-3.5 grams daily in bread or soup for 3-8 weeks does not seem to significantly affect fasting plasma glucose levels or HbA1c when compared with control bread or soup (34765,34788). Also, some evidence shows that consuming soup enriched with beta-glucans does not improve cholesterol levels in patients with type 2 diabetes when compared with control soup (34788). The inconsistency in clinical outcomes may be due to differences in the length of treatment, quantity or ratio of beta-glucans consumed, and/or the preparation of the beta-glucans product. In children with type 1 diabetes, consuming a bedtime snack enriched in beta-glucans appears to prevent hypoglycemia prior to midnight, but does not prevent hypoglycemia at later time points when compared with a control snack (34685). In adolescents with type 1 diabetes, a very small clinical study shows that taking a specific oat product (Betaglucare), providing 6 grams beta-glucans, in three divided doses daily for one week is beneficial for glycemic control and variability when compared with a standard diet without beta-glucans or with 3 grams beta-glucans daily. Maximal, mean, and pre- and post-meal blood glucose levels were modestly lower, and minimal blood glucose levels were modestly higher. Most measures of glycemic variability were statistically different, although there were no differences in the durations of hypoglycemia or hyperglycemia between groups (105261). However, a small crossover study in adults with type 1 diabetes shows that taking a specific product (Stomacol, Brainbridge Commerce AB) containing beta-glucans 1.53 grams 3 times daily prior to meals for 2 weeks does not alter blood glucose levels when compared with placebo (97983).
• Exercise-induced respiratory infections. There is conflicting evidence about the effects of beta-glucans on respiratory infections in athletes following competitive events. Details: Taking a specific product containing oat beta-glucans (OatVantage) 5.6 grams daily for 14 days does not reduce the number of sick days or the number of upper respiratory tract infections in trained male cyclists when compared with placebo (34746). However, other clinical research shows that taking yeast-derived beta-glucans 250-500 mg daily for 4 weeks beginning on the day after a marathon reduces the occurrence of symptomatic upper respiratory infections by 33% to 50% within 2-4 weeks of treatment when compared with placebo. Health scores, fatigue, and mood also improved (34860,92659). Additional clinical research in marathon runners shows that drinking a beverage containing yeast-derived beta-glucans 250 mg daily for 45 days prior to, the day of, and 45 days after a marathon does not reduce the duration or number of upper respiratory infections, but does seem to reduce the number of symptomatic days and overall severity of upper respiratory symptoms, when compared with placebo (103886). Finally, clinical research in top athletes also shows that taking a specific product containing mushroom-derived beta-glucans (Imunoglukan P4H, PLEURAN s.r.o.) 200 mg with vitamin C 200 mg daily for 3 months reduces the number of subjects with at least four symptoms of upper respiratory tract infection by approximately 85% when compared with vitamin C alone (34809).
• Fibromyalgia. Although there is interest in using oral beta-glucans for fibromyalgia, there is insufficient reliable information about the clinical effects of beta-glucans for this condition.
• Hepatitis. Although there is interest in using oral beta-glucans for hepatitis, there is insufficient reliable information about the clinical effects of beta-glucans for this condition.
• Hypertension. It is unclear if oral beta-glucans are beneficial for hypertension; the available evidence is conflicting. Details: Preliminary clinical research shows that consuming an oat cereal containing beta-glucans 5.52 grams daily for 6 weeks reduces diastolic and systolic blood pressure when compared with a low-fiber cereal in hypertensive adults (34691). However, other clinical research shows that consuming oat-based cereals enriched in beta-glucans for 12 weeks does not reduce blood pressure in individuals with hypertension. A reduction in blood pressure occurred in a sub-group of these individuals with a body mass index greater than 31.5 kg/m2 (34684,34722).
• Inflammatory bowel disease (IBD). Oral beta-glucans have only been evaluated in combination with other ingredients; their effect when used alone is unclear. Details: Preliminary clinical research in adults with IBD and symptoms of irritable bowel syndrome shows that taking a combination of beta-glucans, inositol, and digestive enzymes daily for 4 weeks, in conjunction with mesalamine, reduces evacuative urgency when compared with mesalamine alone. Taking this combination product also reduces abdominal pain, bloating, and gas when compared with baseline, but not when compared with taking mesalamine alone (97984).
• Irritable bowel syndrome (IBS). Oral beta-glucans have only been evaluated in combination with other ingredients; their effect when used alone is unclear. Details: Preliminary clinical research shows that taking one pill twice daily of a specific combination product (Biointol, BioActivaL) containing beta-glucans, inositol, and digestive enzymes for 4 weeks reduces pain, bloating, and gas, but not other symptoms of IBS, when compared with no treatment (34818). It is not clear if these effects are due to beta-glucans, the other ingredients, or the combination.
• Laser skin resurfacing. It is unclear if topical beta-glucans are beneficial for improving recovery from laser skin resurfacing. Details: In patients that had received fractional laser therapy for atrophic acne scars, preliminary clinical research shows that topical application of skin care products containing beta-glucans, including dressings, solutions, and creams, (Dermdoc, Songyang Biotechnology Co. Ltd) once daily to one side of the face for 14 days modestly increases hydration and reduces redness when compared with the other side of the face treated with the vehicle alone (105263).
• Lower respiratory tract infections. Oral beta-glucans have only been evaluated in combination with other ingredients; their effect when used alone is unclear. Details: Preliminary clinical research in children aged 2-6 years with recurrent respiratory tract infections shows that taking a specific combination product (Stimunex gocce) containing beta-glucans, elderberry extract, zinc, and vitamin D3 does not reduce the number or duration of lower respiratory tract infections when compared with no treatment. In the four months after treatment completion, the number of infections was reduced by about 50%; however, the total number of infections in each group was small. The dose was 1 drop/kg daily for one month, followed by 1 drop/kg daily for 15 consecutive days each month for the next three months (109212).
• Lyme disease. Although there is interest in using oral beta-glucans for Lyme disease, there is insufficient reliable information about the clinical effects of beta-glucans for this condition.
• Metabolic syndrome. It is unclear if oral beta-glucans are beneficial for metabolic syndrome. Details: Preliminary clinical research in adults with metabolic syndrome or at high risk for metabolic syndrome shows that eating 200 grams of bread enriched with 6% barley-derived beta-glucans daily for 4 weeks as part of the diet does not alter most metabolic parameters when compared with baseline. However, there was a small reduction in total cholesterol (100185). The validity of this finding is limited by the lack of a comparator group.
• Multiple sclerosis (MS). Although there is interest in using oral beta-glucans for MS, there is insufficient reliable information about the clinical effects of beta-glucans for this condition.
• Neuroblastoma. It is unclear if oral beta-glucans is beneficial in children or young adults with neuroblastoma. Details: Clinical research in children and young adults with relapsed or refractory high-risk neuroblastoma shows that taking yeast-derived beta-glucans for 17 days, starting four days before treatment with intravenous anti-GD2 murine monoclonal antibody for a total of 10 days, results in progression-free and overall survival rates of 28% and 61%, respectively, after 2 years, and 19% and 36%, respectively, after 5 years. Doses of beta-glucans ranged from 10-200 mg/kg daily and each patient completed 1-4 treatment cycles (109203). The validity of these findings is limited by the lack of statistical comparison to a control group. A large clinical study in children and young adults with high-risk neuroblastoma receiving subcutaneous GD2/GD3 vaccine shows that taking beta-glucans 40 mg/kg/day for 14 days as a primer to the vaccine improves the IgG antibody response at 32 weeks when compared with controls who started taking beta-glucans 6 weeks after vaccination. However, taking beta-glucans prior to vaccination does not improve overall or progression-free survival at approximately 20 months (112227). This study may have been inadequately powered to detect a difference in survival between groups.
• Obesity. It is unclear if oral beta-glucans are beneficial for obesity. Details: A meta-analysis of 20 randomized controlled trials shows that taking beta-glucans reduces body weight by about 0.8 kg and body mass index (BMI) by about 0.6 kg/m2 when compared with not taking beta-glucans. However, there was no effect on waist circumference. Also, populations included in this meta-analysis included those with obesity, as well as healthy individuals and patients with diabetes or hypercholesterolemia (100183). Results from individual clinical trials are mixed, with some showing modest reductions in body weight, BMI, and/or waist circumference, and others showing no effect (34790,98202,98203,100183,109208). This research has evaluated barley-, oat-, or yeast-derived beta-glucans at doses between 0.88-9 grams daily for 0.4-12 weeks (34790,98202,98203,100183,109208). Also, a capsule containing yeast-derived beta-glucans 477 mg has been taken daily for 2 weeks, then twice daily for 4 weeks (98203). Beta-glucans have also been taken in combination with other ingredients. For example, barley-derived beta-glucans 2.2 grams has been mixed with rice and consumed twice daily with meals for 12 weeks (98202) and oat-derived beta-glucans (B-Can, Garuda International, Inc.) 2.5 grams has been taken with green coffee polyphenols 300 mg twice daily for 8 weeks (109208). The inconsistency in clinical outcomes may be due to the heterogenous patient populations, as well as the differing sources, doses, and dosage forms of beta-glucans used.
• Otitis media. Although there is interest in using oral beta-glucans for otitis media, there is insufficient reliable information about the clinical effects of beta-glucans for this condition.
• Postoperative pain. It is unclear if oral beta-glucans are beneficial for reducing abdominal pain after surgery for intestinal polyps. Details: Preliminary clinical research in patients who underwent surgical removal of intestinal polyps shows that eating bread containing barley beta-glucans 3 grams daily for 3 months reduces bloating and abdominal pain when compared with eating bread that does not contain beta-glucans (34813).
• Respiratory tract infections. Oral beta-glucans have only been evaluated in combination with other ingredients; their effect when used alone is unclear. Details: Preliminary clinical research in children aged 2-6 years with recurrent respiratory tract infections shows that taking a specific combination product (Stimunex gocce) containing beta-glucans, elderberry extract, zinc, and vitamin D3 reduces the duration of respiratory tract infections by about 1.7 days and modestly improves parent-perceived symptom severity and effectiveness when compared with no treatment. However, there was no effect on the number of total, upper, or lower respiratory tract infections, the use of antibiotics or antipyretics, or the number of days missed from school. The product was dosed as 1 drop/kg daily for one month, followed by 1 drop/kg daily for 15 consecutive days each month for the next three months (109212).
• Rheumatoid arthritis (RA). Although there is interest in using oral beta-glucans for RA, there is insufficient reliable information about the clinical effects of beta-glucans for this condition.
• Stretch marks (striae distensae). It is unclear if topical beta-glucans are beneficial for stretch marks. Details: Preliminary clinical research shows that a specific topical serum and emulsion (Awake; Hangzhou Songyang Biotechnical) containing beta-glucans, applied twice daily for 12 weeks, modestly improves patient-scored, but not physician-scored, stretch mark appearance when compared with a vehicle control. When beta-glucans are used in combination with 1565-nm non-ablative fractional laser once every 4 weeks for 12 weeks, scar atrophy is modestly improved when compared with either treatment alone (109210). However, it is unclear if any changes would be considered clinically significant.
• Upper respiratory tract infection (URTI). It is unclear if oral beta-glucans are beneficial for the prevention of URTIs in adults or children. Details: A meta-analysis of clinical research shows that taking yeast-derived beta-glucans reduces the odds of developing a URTI in generally healthy individuals by approximately 65% when compared with placebo. There was also a small to medium effect on the overall incidence and duration of URTIs. Doses ranged from 35-900 mg daily for 4-26 weeks (105264). However, the results from this analysis were heterogeneous and the number of studies included was small. One study included in the analysis used a specific product containing yeast-derived beta-glucans (Wellmune WGP) 500 mg daily for 12 weeks and found no effect on the number or duration of overall symptomatic infections or the number or duration of specific types of respiratory infections when compared with placebo. However, there was an improvement in quality of life and a reduction in the number of missed work days (34879). Beta-glucans have also been evaluated for the prevention of URTI in children. A small clinical study in children aged 2-6 years with recurrent respiratory tract infections shows that taking a specific combination product (Stimunex gocce) containing beta-glucans, elderberry extract, zinc, and vitamin D3 does not reduce the number or duration of upper respiratory tract infections when compared with no treatment. At four months after treatment completion, the number of infections was reduced by about 44%; however, the total number of infections in both groups was small. The product was dosed as 1 drop/kg daily for one month, followed by 1 drop/kg daily for 15 consecutive days each month for the next three months (109212).
• Wound healing. Although there is interest in using topical beta-glucans for healing of wounds, burns, skin ulcers, and dermatitis, there is insufficient reliable information about the clinical effects of beta-glucans for these purposes. More evidence is needed to rate beta-glucans for these uses.

• Alzheimer disease. It is unclear if oral lion's mane mushroom is beneficial in patients with Alzheimer disease. Details: Preliminary clinical research in patients over 50 years of age with mild Alzheimer disease shows that taking lion's mane mushroom mycelia (standardized to contain 5 mg/gram of erinacrine A) 1.05 grams daily for 49 weeks improves performance of activities of daily living when compared with placebo. It also improves scores on the Mini-Mental State Examination when compared with baseline (105546). The validity of these findings is reduced by the lack of an intention to treat analysis, and the comparison of some outcomes to baseline instead of placebo.
• Anxiety. Although there is interest in using oral lion's mane mushroom for anxiety, there is insufficient reliable information about the clinical effects of lion's mane mushroom for this condition.
• Athletic performance. Although there is interest in using oral lion's mane mushroom for improving athletic performance, there is insufficient reliable information about the clinical effects of lion's mane mushroom for this purpose.
• Cancer. Although there is interest in using oral lion's mane mushroom for cancer, there is insufficient reliable information about the clinical effects of lions mane mushroom for this purpose.
• Cognitive function. Small clinical trials suggest that lion's mane mushroom does not improve cognitive function. Details: A small clinical trial shows that taking lion's mane mushroom 3.2 grams daily for 12 weeks does not improve most measures of cognitive function when compared with placebo in middle aged to older adults (101770). Additional clinical research in younger adults shows that taking lion's mane mushroom 10 grams daily for 4 weeks does not improve markers of cognition during a period of exercise-induced fatigue when compared with taking placebo. The lion's mane product is 50% dried mushroom and 50% extract (111932). These studies were small and may have been underpowered to detect differences.
• Cognitive impairment. It is unclear if oral lion's mane mushroom is beneficial in patients with mild cognitive impairment. Details: One clinical study in Japanese patients aged 50-80 years old with mild cognitive impairment shows that taking lion's mane mushroom powder 1 gram three times daily for 16 weeks increases cognitive function when compared with placebo. However, cognitive function regresses within 4 weeks of treatment termination (91999).
• Coronavirus disease 2019 (COVID-19). Although there has been interest in using oral lion's mane mushroom for COVID-19, there is insufficient reliable information about the clinical effects of lion's mane mushroom for this purpose.
• Dementia. Although there is interest in using oral lion's mane mushroom for dementia, there is insufficient reliable information about the clinical effects of lion's mane mushroom for this condition.
• Depression. It is unclear if oral lion's mane mushroom is beneficial in patients with depression. Details: Preliminary clinical research in perimenopausal patients without a formal diagnosis of depression shows that eating 4 cookies daily, each containing 0.5 grams powdered lion's mane mushroom, for 4 weeks is similarly effective to placebo cookies for reducing scores on a depression scale (105547).
• Diabetes. Although there is interest in using oral lion's mane mushroom for diabetes, there is insufficient reliable information about the clinical effects of lion's mane mushroom for this condition.
• Gastritis. It is unclear if oral lion's mane mushroom is beneficial in patients with chronic atrophic gastritis. Details: Preliminary clinical research in patients with chronic atrophic gastritis shows that taking lion's mane mushroom (unknown dose) before meals daily for 3 months improves upper abdominal pain in about 27% more patients, improves dyspepsia in about 39% more patients, and reduces inflammatory infiltration in about 23% more patients when compared with placebo (92630).

LIKELY SAFE ...when used orally in amounts commonly found in foods. Beta-glucans derived from oat bran, baker's yeast, or brewer's yeast (Saccharomyces cerevisiae) have Generally Recognized as Safe (GRAS) status in the US (4912).

POSSIBLY SAFE ...when used orally and appropriately, short-term in medicinal amounts. There is some evidence that yeast-derived beta-glucans 15 grams daily can be used safely for up to 8 weeks (7272). Oat-derived beta-glucans 3-10 grams daily can also be used safely for up to 12 weeks (7272,5796,17129,34700,34727,34729,34765,34766,34811,34812)(34876,107935,109206). ...when used topically and appropriately. A specific beta-glucans serum and emulsion (Awake; Hangzhou Songyang Biotechnical) combination has been used with apparent safely for up to 12 weeks in clinical research (109210). A specific beta-glucans cream (Imunoglukan P4H, PLEURAN s.r.o.) has been used with apparent safety 2-3 times daily for up to 6 months (98201).
