l-carnitine

 1. also known as l-carnitine carnitine, vitamin BT, is a naturally occurring compounds in human cells, chemical name for β-hydroxy-γ-n-trimethyl ammonium acid, bio-synthesis of l-carnitine on their own, part food are also available. Within the cell, l-carnitine's basic function is as a carrier from China in the mitochondrial inner membrane in mitochondria of fatty acids. Because the fatty acids (as well as other energy sources) are to be used can be oxidized in the mitochondria release energy, outside of the mitochondria in fatty acids cannot be oxidized and release energy. So, it's easy to give a false impression, like l-carnitine is key to fat oxidation.

2. However, in practice, l-carnitine is a means of delivery, like transport of fat. As for how many fat consumption, does not depend on l-carnitine. It's like covering building bricks are needed to transport, but how many bricks does not depend on the car's floor consumption, but depending on the size and structure of the building. Simply put, if the intensity (energy consumption) small, fat little l-carnitine does not only increase fat oxidation function, therefore no help to lose weight. Under normal circumstances (amount is not very large), the human body would undertake the adequate synthesis of l-carnitine, l-carnitine deficiency problem does not occur. Only if the amount is large, such as athletes or sporting person, consume more energy per unit of time, fat oxidation for "traffic" is a large can (many studies support, studies have reported negative) is l-carnitine synthesis "relatively low". At this point, additional administration of l-carnitine, expanding the fleet (carrier) size, in the unit of time to site (mitochondrial) shipment of more bricks (fatty acids) is clearly beneficial to consume more fat oxidation.

3. l-carnitine is not a weight-loss drug, its main role is to transport burn fat to mitochondria, is a carriage of enzymes. Want to use l-carnitine losing weight, must be combined with appropriate exercise and diet.
