Evidence notes
Multiple human studies suggest benefits for anxiety and sleep, but methodological quality is often poor, sample sizes modest, and standardization of extracts varies widely. Fruiting body extracts show more promising data than mycelium. Insufficient evidence for strong A or B grade.
Grade C: Mostly observational or small trials; mechanism is plausible but unproven at scale.
