The L-Carnitine is an oligopeptide consisting of two essential amino acids, lysine and methionine, which act as a natural constituent of cells and develop a role in the metabolism of lipids for the muscles. The best-known function of carnitine is its essential role in transporting long-chain fatty acids into mitochondria for b-oxidation, thus being of fundamental importance in lipid metabolism and energy production for the myocardium and muscles. The lack of L-Carnitine prevents fats to be transported to the energetic point, where they will be burnt. As a consequence of the accumulation of fat results orange skin and cellulite. By contrast, the more L-Carnitine, the more fat is burnt and therefore, we loose weight, we recover energy and our resistance to cold and fatigue increases.
