Lion's Mane Mushroom [Discontinued] by Peak Performance

INSUFFICIENT RELIABLE EVIDENCE to RATE

• 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).
• Hyperlipidemia. Although there is interest in using oral lion's mane mushroom for hyperlipidemia, there is insufficient reliable information about the clinical effects of lion's mane mushroom for this condition.
• Memory. Although there is interest in using oral lion's mane mushroom for memory, there is insufficient reliable information about the clinical effects of lion's mane mushroom for this purpose.
• Multiple sclerosis (MS). Although there is interest in using oral lion's mane mushroom for MS, there is insufficient reliable information about the clinical effects of lion's mane mushroom for this condition.
• Obesity. Although there is interest in using oral lion's mane mushroom for obesity, there is insufficient reliable information about the clinical effects of lion's mane mushroom for this condition.
• Parkinson disease. Although there is interest in using oral lion's mane mushroom for Parkinson disease, there is insufficient reliable information about the clinical effects of lion's mane mushroom for this condition.
• Peptic ulcers. Although there is interest in using oral lion's mane mushroom for peptic ulcers, there is insufficient reliable information about the clinical effects of lion's mane mushroom for this condition.
• Wound healing. Although there is interest in using topical lion's mane mushroom for wound healing, there is insufficient reliable information about the clinical effects of lion's mane mushroom for this condition. More evidence is needed to rate lion's mane mushroom for these uses.

Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, lion's mane mushroom may have additive effects when used with antidiabetes drugs.  Details Animal research suggests that an aqueous extract of lion's mane mushroom can reduce serum glucose and increase serum insulin (91996).

IMMUNOSUPPRESSANTS Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, concurrent use of lion's mane mushroom might interfere with immunosuppressive therapy.  Details In animal and in vitro research, lion's mane mushroom polysaccharides stimulate the immune system (91933,111933).
