Performance
Cordyceps (Cordyceps militaris)
Also known as: Cordyceps militaris, cordyceps extract, cordyceps mycelium, yartsa gunbu
Cordyceps militaris is a parasitic fungus traditionally used in Himalayan and Tibetan medicine to support energy and stamina. Limited human evidence suggests potential benefits for aerobic performance and fatigue, though study quality is modest.
Primary uses
- energy support
- athletic performance
- oxygen utilization
- stamina
How it works
- adenosine triphosphate (ATP) synthesis enhancement
- mitochondrial function support
- oxygen uptake and utilization
- lactate clearance
Dosage
- Typical range
- 1,000–3,000 mg daily (dried mycelium biomass)
- Timing
- morning or pre-exercise for optimal energy support
- With food
- may be taken with or without food
- Duration
- May require 4–8 weeks for performance effects; safe for chronic use
- Special populations
- Athletes should verify compliance with sport-specific anti-doping regulations
Forms
- mycelium biomass on rice· 70/100
- extract· 70/100
- powder· 70/100
Safety
Common side effects
- rare: mild GI upset, insomnia if taken late in day
Contraindications
- stimulant sensitivity
- uncontrolled hypertension (potential stimulant-like effects)
Evidence notes
Few human clinical trials exist; most evidence is from animal and in vitro studies. Limited small human studies show mixed results for athletic performance. More rigorous RCTs needed.
Grade C: Mostly observational or small trials; mechanism is plausible but unproven at scale.
