Carnitine is a substance found in almost every cell in the body, it is biosynthesized from the amino acids lysine and methionine. The compound plays a crucial role in energy production, as it is responsible for transporting fatty acids to the mitochondria. Carnitine transports waste and toxic compounds out of the mitochondria, preventing their buildup. Given these key functions, skeletal and cardiac muscle that use fatty acids as a dietary fuel have high concentrations of carnitine. Carnitine has also been proposed as a possible treatment for a number of health conditions including heart failure, angina, heart attack, and diabetic neuropathy.
