L-Carnitine is a naturally occurring amino acid that works with the body to help deliver fatty acids into cells where they can be burned as a source of fuel. It helps transport fatty acids into the power centers of the cells (called mitochondria) so that it can be converted into energy. Optimal amounts of L-Carnitine supports the body’s metabolism in processing fat and producing energy. For best results, include L-Carnitine supplementation as part of a healthy diet and exercise program.
