Cordyceps for Athletes: Endurance, Dosage and Timing

Short answer: cordyceps has been studied in human trials of exercise tolerance. In a trial of 28 recreationally active adults, a 4 g daily mushroom blend containing Cordyceps militaris improved VO2 max, time to exhaustion and ventilatory threshold after 3 weeks, though not after 1 week. Not every study agrees: a 2004 study of a Cordyceps sinensis product in trained cyclists found no gain in endurance performance. Take it daily for at least 3 weeks, alongside training, before judging.

For short, explosive efforts rather than endurance, creatine has the stronger research base; our Creatine Monohydrate Powder (5 g per scoop) is coming soon.
