L-carnitine also named as Levocarnitine, which is an amino acid derivative. Levocarnitine facilitates long-chain fatty acid entry into mitochondria, delivering substrate for oxidation and subsequent energy production. Fatty acids are utilized as an energy substrate in all tissues except the brain.

Carnitine is a type of vitamin B, and its structure is similar to that of amino acids. It is mainly used to help transport long-chain fatty acids to provide energy and to prevent fat from collecting in the heart, liver, and skeletal muscles. Carnitine can prevent disordered fat metabolism due to diabetes, fatty liver disease and heart disease, and it can reduce heart damage, lower blood triglyceride, aid in weight loss, and increase the antioxidant effects of vitamin E and C.

L-carnitine Uses

Carnitine is a quaternary amine that occurs naturally in most mammalian tissue. It is present in relatively high concentrations in skeletal muscle and heart where it is involved in regulating energy metabolism. It shifts glucose metabolism from glycolysis to glycogen storage and enhances the transport of long chain fatty acids into the mitochondria where they are oxidized for energy production.

L-Carnitine is a natural, vitamin-like nutrient wich plays an important role inhuman metabolism. It is essential in the utilization of fatty acids and in transporting metabolic energy.
