L-carnitine is very similar to the nonessential amino acid carnitine. It performs some of the same functions, such as helping metabolize food into energy. L-carnitine is synthesized in the body from the amino acids lysine and methionine. L-carnitine transfers long-chain fatty acids, such as triglycerides into mitochondria (a cell's energy powerhouse), where they may be oxidized to produce energy. L-carnitine is a very popular supplement that promotes muscle growth and development. It is also used for fat-burning, increasing energy, and improving resistance to muscle fatigue.
