Ubiquinol is the reduced and active free radical quencher form of Coenzyme Q10 (CoQ10). CoQ10 is found in all cells of the body, with especially high concentrations in the heart, and is essential to mitochondrial energy production and functions as a powerful, fat soluble, free radical scavenger. These properties make Ubiquinol an ideal supplement for the support of energy production and free radical protection in the heart, vascular structures, brain and neurons. Ubiquinol has been shown to be highly bioavailable and the addition of MCT Oil (medium chain triglycerides) to this product naturally improves its solubility and enhances intestinal absorption, thereby creating a product with superior biological value. Active Form of CoQ10.
