Quick Take

Possible help for fatigue and exercise tolerance, but evidence is mixed and quality varies a lot by extract.

Cordyceps is a medicinal fungus genus that in nature grows parasitically on insect larvae; supplement products usually contain cultivated Cordyceps militaris or fermented Ophiocordyceps sinensis mycelium rather than wild-harvested fungus. Its key compounds, including beta-glucans and cordycepin-like nucleosides, may influence cellular energy use and immune signaling. Human evidence suggests modest benefits for exercise tolerance and fatigue, with much weaker data for immune and cardiometabolic markers. It is most worth considering for adults who want to trial a mushroom extract for energy or e

People who prefer mushroom-based supplements

How It Works

Cordyceps appears to affect adenosine-related signaling, mitochondrial energy production, and nitric-oxide pathways, which may slightly improve oxygen use during exertion. Its beta-glucans and other fungal compounds also interact with immune cells, altering cytokine and NK-cell activity.
