Amino Acids



L-carnitine is a chemical substance that occurs naturally in animals and plants. It is composed of two amino acids, lysine and methionine. Its main function is to transport fatty acids into the cells, where they are burned to produce energy. L-carnitine was isolated in 1905 by Russian researchers. In its synthetic form, it was introduced in the 1960s as a dietary supplement. Its popularity increased in the following decades due to studies suggesting that L-carnitine can increase athletic performance and improve cardiovascular health. Today, L-carnitine is available as a dietary supplement with a great scientific basis, free of side effects, and affordable for easy consumption.
