What is Cordyceps?

In plain words

Cordyceps supplements come from fungi, not plants. The body breaks down and processes their different components, which may affect how cells use energy and send immune signals. Researchers study these products for fatigue, exercise performance, and immune function. Human studies are limited, and products can differ greatly in their contents.

Technical definition

Cordyceps is a fungal supplement category derived from species such as Cordyceps militaris and Ophiocordyceps sinensis, formerly classified as Cordyceps sinensis, rather than a single molecular compound. Constituents include polysaccharides and nucleosides such as adenosine and cordycepin (3′-deoxyadenosine), with composition varying by species and preparation; proposed mechanisms involve purine metabolism and immune signaling rather than one established receptor target. Cordyceps products are marketed as dietary supplements in the United States, not FDA-approved treatments for disease.
