L-carnitine tartrate is formed from the combination of L-carnitine tartrate (organic acid) in a single molecule, increasing the interaction (synergism) of each of the substances used. L-carnitine is supplied to the body from the outside through animal food (mutton, beef, venison) or a combination of amino acids (lysine and methionine). It participates in the transport of long-chain fatty acids into the mitochondria of the cell where they are burned. Tartrate reduces the deposition of fatty acids in the cells, thereby enhancing the effects of L-carnitine. It is recommended in endurance sports supplementation, as a dietary supplement for people on a slimming diet and to supplement the shortage of l-carnitine of people not consuming meat products (vegans).
