Maitake
Grifola frondosa
Maitake (Grifola frondosa, also called 'Hen of the Woods') is a medicinal mushroom traditionally used in Japanese and Chinese medicine. The most-researched bioactive is the D-fraction polysaccharide complex (specifically MD-fraction, a beta-1,6-glucan with beta-1,3-glucan branches) - widely studied for immune modulation and as cancer adjunct therapy.

How it works
Maitake bioactives drive multiple effects:
D-Fraction Beta-Glucans
Activate dendritic cells, macrophages, NK cells via dectin-1 and complement receptor 3 - shifts immune balance toward Th1.
MD-Fraction (specific isolate)
More-purified D-fraction with greater immune-modulating potency.
Glucose Regulation
Some studies show improved insulin sensitivity and reduced fasting glucose - mechanism unclear, possibly via beta-glucan delaying GI carbohydrate absorption.
Cholesterol Reduction
Beta-glucan binds bile acids in intestine, reducing reabsorption and lowering serum cholesterol - same mechanism as oat beta-glucan.
Cancer Adjunct
Multiple Japanese trials support use alongside chemotherapy for immune support and quality-of-life improvements.
What to expect
Days 1-14: subtle subjective effects.
Weeks 2-12: peak immune effects.
Long-term continuous use traditional.
Evidence
Claims we could not support
No abstract we checked supports these for this molecule at this route. That is not the same as saying they are false — it marks where the evidence is missing.
Dose/route: 500mg-3g daily; Oral capsule, powder, or liquid extract; 1-3x daily. No checked live PubMed abstract verified this exact displayed dose, route, and frequency for the same molecule/formulation and relevant population.
Mechanism: Maitake bioactives drive multiple effects: 1. D-Fraction Beta-Glucans: Activate dendritic cells, macrophages, NK cells via dectin-1 and complement receptor 3 - shifts immune balance toward Th1. 2. MD-Fraction (specific isolate): More-purified D-fraction with greater immune-modulating potency. 3. Glucose Regulation: Some studies show improved insulin sensitivity and reduced fasting glucose - mechanism unclear, possibly via beta-glucan delaying GI carbohydrate absorption. 4. Cholesterol Reduction: Beta-glucan binds bile acids in intestine, reducing reabsorption and lowering serum cholesterol - same mechanism as oat beta-glucan. 5. Cancer Adjunct: Multiple Japanese trials support use alongside chemotherapy for immune support and quality-of-life improvements.. No checked live PubMed abstract provided an exact-molecule/formulation sentence supporting this source-JSON mechanism claim.
Primary safety claim: No primary safety text present in source JSON. No checked live PubMed abstract directly verified this source-JSON safety claim at the displayed formulation, route, and regimen.
