Double Strength Cardiovascular Health Supports Healthy Serum Lipids Coenzyme A PrecursorPantethine is a highly absorbable and biologically active form of pantothenic acid (Vitamin B-5). Pantethine forms the reactive component of Coenzyme A (CoA) and the acyl-carrier protein (ACP). CoA and ACP are extensively involved in carbohydrate lipid and amino acid metabolism. In addition to possessing the metabolic activity of pantothenic acid, Pantethine helps to support healthy serum lipids. Pantethine is also important for healthy cardiovascular function through its antioxidant activity.
