Coenzyme Q10 (CoQ10 or Q10) is important for your heart health.  It is a catalyst that creates energy on a cellular level and is essential to produce ATP (adenosine triphosphate). ATP is like our battery of life and is produced in the mitochondria of cells. CoQ10 is needed for mitochondrial ATP synthesis. Ubiquinone and ubiquinol are both forms of CoQ10, but ubiquinone is the form of CoQ10 that commonly is found in stores. Ubiquinone is in the oxidative form and, when taken, it’s converted into the reduced form of CoQ10 called ubiquinol. CoQ10 also works as an antioxidant.  Aging is associated with decreased CoQ 10 levels in muscular tissue, for example, your heart.
