NOW&ampreg; Ubiquinol contains the reduced form of CoQ10 (Coenzyme Q10) which has been shown in scientific studies to be a highly bioavailable and active antioxidant form of CoQ10. &ampnbsp;The addition of MCT Oil (medium chain triglycerides) to this product naturally improves its solubility, which further enhances intestinal absorption, and thereby provides superior overall biological value. &ampnbsp;Coenzyme Q10 is present in almost all cells, where it is necessary for mitochondrial energy production. &ampnbsp;The body's highest concentrations of CoQ10 are found in the heart, where constant chemical energy availability is imperative. &ampnbsp;In addition to its benefits for cardiac function through energy production, CoQ10 also functions as a powerful fat soluble antioxidant, providing protection against free radical attack for vascular structures, as well as for other issues, including the brain and neurons.*
