Powerful Antioxidant and Cardiac Support! Coenzyme Q10 occurs naturally in every cell in the body and plays a critical role in the production of energy at the cellular level. Studies have found that the aging process diminishes the body's supply of CoQ10, and that many health benefits are achieved by adding this nutritional supplement to the diet. Because it is a powerful antioxidant, CoQ10 slows and scavenges free-radical biological systems that are known to damage the body's cells. As a supplement, CoQ10 has received particular attention in the prevention and treatment of cardiovascular disease, and is an approved treatment for congestive heart failure in Japan. In addition to its great boost to heart health, CoQ10 plays a role in blood glucose disposal, and can assist in weight loss by stimulating metabolism.
