Solaray Ubiquinol -- 50 mg

What the brand says

Sold as “Solaray Ubiquinol -- 50 mg - 30 Softgels”

Ubiquinol, the reduced form of CoQ10, is an important part of the Coenzyme Q Cycle, and must be present in order for the body to produce energy. Because about 90% of Ubiquinone consumed in the diet is converted to Ubiquinol, a Ubiquinol supplement may be better suited for people who have trouble converting Ubiquinone to Ubiquinol.
