Acetyl L Carnitine helps in the metabolism of long chain fatty acids in the energy cycle. It is synthesised in the liver, brain and kidneys from the essential amino acids, Lysine and Methionine. The body also needs Vitamin C, Iron, Niacin and Vitamin B6 to produce Carnitine. L-Carnitine may also help conserve glycogen supplies in the muscles, increasing exercise tolerance.

Acetyl L Carnitine helps the body metabolise fatty acids for energy and may aid in weight loss and aerobic endurance

L carnitine is derived from the lysine and methionine amino acids. It is mainly synthesized in the liver
and the kidneys, and must be transported for use to other tissues in the body. It is found in highest
concentration in tissues that use fatty acids as the main dietary fuel, such as the skeletal and cardiac
muscles.

One of the key uses of Acetyl L-Carnitine supplement is for fatty acid oxidation - helping users burn unwanted body fat. Fatty acids are one the key energy sources the body uses, and oxidation is the process by which they're broken down to create energy. The fatty acids cannot penetrate the inner mitochondia membrane (where they are burned for energy), and the key role for L-Carnitine is to trasport fatty acids accross the mitochondra membrane to allow for oxidation of the fats.
