L-Carnitine is a dipeptide (formed from two amino acids) that provides support for endurance exercise and recovery from high intensity exercise. It is found in the mitochondria (powerhouses of cells) where it facilitates fat metabolism and energy production. L-Carnitine is also heart healthy, as the hear in particular is reliant on L-Carnitine for the production of energy from fat. This formulation provides Free Form L-Carnitine for optimal absorption and assimilation. It also provides Pantothenic Acid, part of a key coenzyme involved in energy release from cells.
