Coenzyme Q10 (or ubiquinone) is an antioxidant naturally produced by the body. It serves many functions related to growth, energy, and overall healthy function of the body’s tissues. Normally, the body makes all the CoQ10 needed, but this production declines with age and other causes. Coenzyme Q10 supplements can help supply needed CoQ10. However, even people with healthy levels of CoQ10 can take supplements to provide additional antioxidant and anti-inflammatory protection. That may help with common health problems like high blood pressure or diabetes. Coenzyme Q10 has no standard dosages, so people must decide how much CoQ10 they take.
