Fat Metabolism Starts with the Amino Acid L-carnitine

L-carnitine is amino acid essential for the metabolism of fats into a form of energy necessary for extended aerobic activity.

L-carnitine is biosynthesized in the liver and kidneys from lysine and methionine and require the vitamins niacin, B6, C and iron for this reaction to take place. However, the supply of L-carnitine has to be supplemented by the diet, good sources being dairy products, red meat, nuts and seeds, and fruits such as apricots, bananas and avocado. Most of the L-carnitine supply of the body is stored within the muscle tissue. However, it is not unusual for conditions to arise making it difficult for the body to obtain all the carnitine required.

L-carnitine enables fatty acids to be transported into the mitochondria, where cell metabolism occurs.

In simple terms L-Carnitine allows body fats, in the form of triglycerides, to be made more readily available for the generation of energy required for extended exertion. 

In this way, body fats can be used for energy and the supplies of glycogen stored by the liver can be retained for emergency use.

By providing the energy for endurance and stamina in this way, carnitine makes use of an otherwise unavailable energy source, and has the added benefit of reducing body fat stores and reducing strain on the heart.

It is because of these benefits that people who do extended work, exercise vigorously, lose body fat, or are trying to maintain a heart-healthy lifestyle supplement with L-carnitine.
