A coenzyme that functions as part of the electron transport system and as an antioxidant. In patients with congestive heart failure, CoQ10 has been reported to improve cardiac function, including stroke volume and cardiac output. Endurance athletes sometimes use coenzyme Q10 to improve anaerobic and aerobic performance, but scientific studies on the effects of CoQ10 on sport performance are inconclusive. CoQ10 is not on the World Anti-Doping Agency's 2005 Prohibited List.
