Maitake Mushroom (Grifola frondosa)
Rich in unique D-fraction beta-glucans that modulate immune function and help regulate blood sugar levels.
What the evidence says
Most Maitake studies are mechanism or observational rather than RCTs that measure a clinical effect — keep findings provisional.
Most evidence is from high-quality meta-analyses and randomised trials published 2006–2026 with a typical study size of 34 participants.

ModerateWhat the studies found
By outcome
Maitake has an evidence score of 8/10 — strong evidence based on 31 indexed studies, including 1 meta-analysis. Rich in unique D-fraction beta-glucans that modulate immune function and help regulate blood sugar levels.
The commonly studied dose of Maitake is 1-3g dried mushroom or 500-1500mg extract daily. Research points to an estimated optimal dose around 1500mg, with a minimum effective dose near 1000mg. Individual response varies — start low and adjust.
The best time to take Maitake is in the morning. Taking it with food is preferred. Maitake (Grifola frondosa) contains beta-glucans and the unique D-fraction polysaccharide that stimulate innate immune function.

Evidence primarily from cancer adjuvant studies showing immune modulation. One RCT (n=141) showed reduced treatment-related adverse events in cancer patients. Most evidence is preclinical or from systematic reviews without specific dose-response data.
Stronger immune response
More stable blood sugar levels
May support healthy weight
Monitor blood sugar closely; may need medication adjustment
May enhance blood sugar lowering; monitor levels
May have mild antiplatelet effects — may affect platelet aggregation or vitamin K-dependent clotting factors, altering anticoagulant efficacy
Tip: Monitor blood sugar if diabetic
Maitake is generally well-tolerated and considered safe for most healthy adults at recommended doses. The most commonly reported side effects are hypoglycemia. Use caution if any of these apply to you: Known allergy or hypersensitivity to Maitake or related compounds.
