Doctor's Best High Absorption CoQ10 contains pure coenzyme Q10 (Ubiquinone) plus BioPerine®. CoQ10 helps support heart function and is vital to the production of ATP (adenosine triphosphate), especially in the heart. Stress, free radicals, statin medications and aging can impact CoQ10 levels. CoQ10 is very important for the creation of energy, muscular contraction and the synthesis of protein. Studies have shown that BioPerine® increases CoQ10 absorption.
