What is Carnitine?
L-carnitine, a compound present in almost all cells in the body, helps in the process of metabolizing fatty acids into energy. L-carnitine is chemically similar to an amino acid, and is manufactured in the liver and kidneys from the amino acids L-lysine and L-methionine. L-carnitine is naturally occurring in many animal source foods and a few plant source foods such as avocado.

Health Benefits
Because L-carnitine is primarily manufactured in the liver and kidneys, supplementation of the compound in those with liver or kidney disease may be necessary due to impaired L-carnitine synthesis.
