Ubiquinol Increases Power Output

    Coenzyme Q10 is a vitamin like chemical that exists as ubiquinone (oxidized coenzyme Q10) or ubiquinol (nonoxidized form). It is important in energy metabolism in the cells. Some athletes experience coenzyme Q10 depletion during training and might benefit from supplements. Scientisits from Germany found that daily supplementation of 300 milligrams of ubiquinol for six weeks increased power output on a stationary bike compared to a placebo. Separate studies from Turkey and Japan showed that CoQ10 increased peak power, average power and endurance, and reduced the perception of fatigue. Larger doses produced the greatest effects. Coenzyme Q10, particularly in doses of 300 milligrams per day, might prevent fatigue and boost performance during intense exercise. Studies using smaller doses showed that it had no effect on exercise performance. (Journal of the International Society of Sports Nutrition. 10:24, 2013)
