Healthy Origins Vegan Ubiquinol is the active antioxidant form of CoQ10, responsible for the powerful preventative benefits associated with CoQ10. Normally, the conversion process from CoQ10 to Ubiquinol occurs naturally within the body; however, certain individuals may have difficulty with the natural conversion process. Ubiquinol supplementation is important for individuals suffering from specific conditions, especially related to oxidative stress, and those over 40 years of age.
