90% of L-carnitine is found in cardiac cells and skeletal muscle and therefore its deficiency can affect the normal functioning of the heart and muscles. L-carnitine has different fields of action and its main function is to allow energy to be obtained. It is a key element for the oxidation of long-chain fatty acids, introducing them into the mitochondria to release energy in the form of ATP (adenosine triphosphate). L-Carnitine is an amino acid that transports fatty acids accumulated in adipose deposits to the mitochondria, where they are oxidized to obtain energy.
