Ubiquinol is the active / reduced form of Coenzyme Q10 (CoQ10), which is also known as "ubiquinone".
Coenzyme Q10 (CoQ10) is a naturally occurring substance found in every cell of the body. CoQ10 and Ubiquinol help generate energy from oxygen (in the form of adenosine triphosphate (ATP), the energy on which the body runs).
As human and animal nutritional supplements, CoQ10 and ubiquinol are used to boost energy levels and for heart health.
