Reishi is a mushroom used for centuries in East Asian traditional practices. Supplements typically use dried mushroom powder or extracts of the fruiting body or spores.
Why it’s used
Taken to support immune function and general wellness.
What the evidence says
Human clinical evidence for reishi remains limited. Some small trials suggest effects on immune cell activity, but studies are often small, short, and inconsistent in preparation and dosing, and no clear clinical benefit has been well established in humans.
Context
Studied preparations and doses vary widely across trials, from mushroom powders to purified extracts, making direct comparison and dose standardization difficult.
