Cordyceps militaris

Tier 3 — weak evidence · Endurance · Energy · Oxygen utilisation

A medicinal mushroom traditionally used for energy and stamina. A 2024 review of 7 trials found modest improvements in aerobic capacity and exercise endurance. Most positive trials used the cultivated form (C. militaris), not wild cordyceps. Evidence is still inconsistent across studies. Generally safe, but quality varies widely between products.

Dose: 1,000–3,000 mg/day C. militaris extract; CS-4 strain for standardisation
