L-Carnitine-l-tartrate is a highly stabilized form of l-carnitine, an amino acid found abundantly in muscle tissue. It functions primarily to regulate fat metabolism, and also acts as a carrier of fatty acids into the mitochondria, the powerhouses of the cell, where they are oxidized and converted to energy. L-Carnitine also facilitates the removal of short and medium chain fatty acids from the mitochondria that accumulate during normal metabolic processes. Long term supplementation with l-carnitine indicated positive support for cardiovascular health after a 3-year followup in adults. A recent placebo-controlled clinical study conducted at Ball State University in Indiana has found that l-carnitine-l-tartrate supplementation helps physical recovery from high intensity exercise. L-carnitine-l-tartrate contains 68% l-carnitine and 32% natural l-tartaric acid. Usual dose is 2 capsules per day, or as directed by your physician.
