About this supplement
L-Carnitine is a naturally occurring amino acid derivative that plays a crucial role in the metabolism of fatty acids. It is primarily involved in the transport of long-chain fatty acids into the mitochondria, where they are oxidized for energy production. L-Carnitine is synthesized in the body from the amino acids lysine and methionine and is found in high concentrations in tissues that utilize fatty acids as a primary fuel source, such as skeletal and cardiac muscles.
