What Is Cordyceps Militaris?

Cordyceps was traditionally harvested as a parasitic fungus growing on caterpillars in Tibet — now cultivated as Cordyceps militaris on grain, which is more accessible, sustainable, and affordable. It has been used by Chinese Olympic athletes since the 1990s. The active compounds (cordycepin, adenosine, beta-glucans) support mitochondrial energy production.

How It Works: The Science

Cordycepin (3′-deoxyadenosine) is structurally similar to adenosine and modulates mitochondrial AMP/ATP ratios, activating AMPK (the cellular energy sensor). This increases mitochondrial biogenesis and fat oxidation, explaining improved endurance. Cordycepin also increases NO production and may stimulate testosterone production via StAR protein.

Chen et al. (2010) — 3g/day for 6 weeks improved VO₂max in healthy elderly

Reduces fatigue and improves exercise tolerance

moderate

Xu et al. (2009) — significant improvements in time-to-exhaustion

May support testosterone and sexual function

limited

Dosage Guide

Effective Dose

1000–4000mg / day

1000–4000mg/day of Cordyceps militaris powder or 500–1000mg concentrated extract. Cs-4 (fermented Cordyceps sinensis) and Cordyceps militaris are the two most studied forms for exercise performance.

Safety Profile & Side Effects

Well tolerated. Avoid in autoimmune conditions (immune stimulation may worsen). Potential interactions with immunosuppressants and anticoagulants.
