Coenzyme Q10 (or ubiquinone) is a fat-soluble antioxidant found nearly “ubiquitously” in all cells. It functions as a mitochondrial coenzyme and is essential for the production of ATP, the energy source for cellular activity. The biochemical structure of CoQ10 makes it perfectly suited to transfer electrons for ATP production and to clean up free radicals as an antioxidant. Because CoQ10 supports energy production on the cellular level, it is especially important for the healthy function of organs whose cells use a lot of energy such as the heart, blood vessels, muscles, and kidneys. *
