What the research examines
Human clinical research on Reishi has focused on immune modulation, fatigue reduction, and stress adaptation. Trials vary widely in extract concentration and bioactive beta-glucan content, making dose comparisons complex.
Common uses & what to look for
Reishi (Ganoderma lucidum) is commonly included in supplements targeting stress & immunity. When evaluating products, look for brands that publicly disclose their extract concentration, source type (fruiting body vs. mycelium), and beta-glucan content — these details are the markers Cogniscore uses to assign disclosure scores.
Clinical studies have primarily used doses of 1,500–9,000mg per day. Products listing a proprietary blend without disclosing individual ingredient amounts cannot be meaningfully compared against these trial doses.
