L-Carnitine was discovered in 1905 and is biosynthesized by the amino acids Lysine and Methionine. It transports fatty acids into the mitochondria. In animals it is primarily biosynthesized in the liver and the kidney. It is said to increase energy in the body and said by some to be able to help with weight loss. L-Carnitine is sold as a stand alone supplement and is also an ingredient in a number of weight loss products on the market.

Product Features

L- Carnitine can be purchased as a stand alone supplement directly from on line stores or in person from drug stores. It is also found as an ingredient in a number of weight loss supplements. It is found in red meat and in dairy products. Some clinical tests have shown that it can have a stabilizing effect on diabetes. This means that if you have gained weight as a result of diabetes and L- Carnitine helps to stabilize your diabetes a pleasant after effect of this may be some weight loss. However anyone with diabetes should never take a stand alone dietary supplement or a weight loss supplement without first seeking the advice of their family physician or diabetes health care professional.

Some athletes take L-Carnitine supplements due to its supposed ability to help increase the energy in the body. However the claims of those manufactures that include L- Carnitine in their weight loss products are more tenuous. Although a couple of very small scale clinical tests have shown than L-Carnitine can lead to weight loss, larger controlled clinical tests are needed to establish these claims as reliable. There is certainly no evidence that L- Carnitine as an ingredient is any more effective than other popular ingredients in weight loss products such as Green Tea Extract.
