Mushroom complex (multi-species)

Tier 3 — weak evidence · Immunity · Adaptogen · Cognition

Blends of reishi, chaga, cordyceps, turkey tail, and others. Each mushroom has varying levels of evidence individually, but combined blends lack standardized dosing. No trials have tested the specific combinations being sold commercially. You are better off choosing a single mushroom species with evidence for your specific health goal.

Dose: 1–3 g/day mushroom blend; species-specific extracts with standardised beta-glucans preferred
