L-carnitine is a naturally occurring amino acid derivative that plays a crucial role in the production of energy by transporting fatty acids into your cells’ mitochondria.
L-carnitine is the standard biologically active form of carnitine, which is found in your body, foods and most supplements.
L-carnitine’s main role in your body involves mitochondrial function and energy production. In cells, it helps transport fatty acids into the mitochondria, where they can be burned for energy.
About 98% of your L-carnitine stores are contained in your muscles, along with trace amounts in your liver and blood.
