Coenzyme Q10 (CoQ-10) is a naturally occurring compound found in our body’s cells that is intricately involved in energy production. Therefore, as the theory goes, if you can increase your levels of CoQ-10, we may be able to increase energy production/performance. Recent studies seem to support this notion for certain activities and test subjects. Also, as we age CoQ-10 levels decrease, making CoQ-10 supplementation potentially helpful in reducing fatigue in endurance activities/exercise in older people or those with compromised cardiovascular systems.
Because CoQ-10 also works as an antioxidant, it may have the ability to reduce muscle damage caused by exercise.The amount of CoQ-10 supplemented in 3 recent studies that demonstrated enhanced performance (delayed fatigue and reduction in oxidative stress) when compared to a placebo was between 100-300mgs/day.
