Methionine and lysine amino acids are the primary sources of l-carnitine. This substance is manufactured in the kidneys and liver and are transported to other tissues of the body. Medical studies say that high concentration in tissues of these acids help prevent the formation of potentially harmful fatty acids. Small amounts of l-carnitine are produced by the body on a daily basis. Additional supplementation may prevent the build-up of fatty acids in the liver and the heart. Dietary l-carnitine can be easily obtained from many food sources. The best sources of this substance is red meat like beef, sheep, and lamb. Milk, cheese, and poultry products contain some carnitine, while vegetables and fruit contain negligible amounts or none at all. Because of this, individuals should realize adequate consumption of essential amino acids may provide the necessary building blocks for the body to synthesize sufficient quantities of l-carnitine.

L-carnitine aids in weight loss by transferring long-chain fatty acids into the mitochondria or the cell's source of energy. By doing this, these fatty acids can be used to produce energy and burn fat. Aside from its weight-loss properties, l-carnitine may aid in the reduction of nervousness, stress, and irritability that are associated with low carbohydrate eating programs. Additional l-carnitine supplementation may also lead to improved energy, muscle fatigue, and the prevention of cardiovascular diseases and diabetes.
