Coenzyme Q10 (CoQ10) is a naturally occurring compound found in nearly every cell of the body, where it plays a central role in mitochondrial energy production and serves as a powerful antioxidant. Research suggests that CoQ10 supplementation may support cardiovascular health, with studies indicating potential benefits for blood pressure regulation and overall heart function. It has also been investigated for its role in reducing the frequency of migraines, supporting fertility, improving exercise performance, and combating fatigue — particularly in individuals whose natural CoQ10 levels may decline with age or statin medication use. Available primarily as ubiquinone and its more bioavailable reduced form ubiquinol, CoQ10 remains one of the more extensively studied compounds in integrative health research.
