Healthy Origins Co-Q-10 Gels (Ubiquinone) is a naturally occurring substance that facilitates the production of cellular energy. In every cell in your body, there are small "engines" called mitochondria. Ninety-five percent of the total energy created within the body comes from these mitochondria, and none of it can take place without CoQ10.
