Cordyceps militaris

Cordyceps militaris is a species of entomopathogenic fungus traditionally used in Eastern medicine. It is cultivated on various plant-based substrates such as rice or silkworm pupae to produce a biomass rich in bioactive compounds, including cordycepin, polysaccharides, adenosine, and ergosterol.

As a feed ingredient, Cordyceps militaris is included in equine supplements for its potential to influence metabolic, antioxidant, and immune functions, though specific equine studies remain limited. It is generally used in small quantities as a functional or nutraceutical additive.
