Revive Active Ubiquinol is a dietary supplement that provides 100mg of ubiquinol, a form of CoQ10. Coenzyme Q10 (CoQ10) is a fat-soluble, vitamin-like substance made by our bodies. Once produced, it is then used by our cells. CoQ-10 is naturally found in every cell of the body with especially high levels in the heart, skeletal muscles and other tissues with high energy requirements. As we age, our bodies produce less and less CoQ-10.
