What is Ubiquinol?

Ubiquinol is the reduced, active form of Coenzyme Q10, the form your body actually uses to generate ATP in mitochondria and to protect cellular membranes from oxidation. While conventional CoQ10 (ubiquinone) must first be converted to ubiquinol before it works, this conversion becomes progressively less efficient with age and is impaired by statin medications. Direct ubiquinol supplementation bypasses this bottleneck. Clinical research supports its use for cardiovascular health, blood-pressure regulation, and energy in adults over 40. The Japan-developed Kaneka form is the standard used in most published studies. Typical doses are 50-200 mg daily with a fatty meal.
