L-Carnitine is a vitamin-like nutrient that is synthesized in the body, using the amino acids lysine and methionine as precursors. Because the body produces L-Carnitine on its own, it cannot be classified as a vitamin, even though it has functions similar to B vitamins. Fumarate is also a natural compound found in the body. Fumarate serves as an intermediate in the Krebs cycle, a key cellular energy-producing process. L-Carnitine and Fumarate both play important roles in energy metabolism.
Best L-Carnitine contains BIOSINT L-Carnitine Fumarate, which is made in Italy by Sigma Tau Health Science.
