Energy from fatty acids
L-carnitine is an endogenous substance that is formed from amino acids. There are different forms of L-carnitine, of which the most important are acetylcarnitine (ALCAR) and L-carnitine tartrate. While acetylcarnitine is mainly important for the central nervous system, tartrate plays an important role in energy metabolism.
L - Carnitine binds to fatty acids and transports them to the ""power stations of cells"", the mitochondria. There the degradation of the fatty acids takes place - by beta-oxidation - and energy is produced in the form of ATP (adenosine triphosphate). In short, glucose or other carbohydrates normally provide energy - but L-carnitine also enables the body to use fatty acids to produce energy.
Once this energy metabolism has started, the body can live on it for a long time. For this reason, L-carnitine is particularly appreciated by figure-conscious people and endurance athletes such as marathon runners or racing cyclists.
L-carnitine in the diet
The name carnitine comes from the Latin word for meat (""caro"", genitive ""carnis""). This is because the body's own substance was first discovered in muscle tissue. It is therefore not surprising that animal foods such as venison, minced beef or leg of lamb have the highest carnitine content. For this reason L-Carnitin is straight a good addition for vegetarians and Veganer.
The human body can also produce L-carnitine from the amino acids lysine and methionine - these amino acids are abundant in legumes. The majority of L-carnitine is stored in the heart and skeletal muscles.
