Carnitine is an important amino acid found in foods of animal origin, while in our body it is synthesized from lysine in the presence of vitamin C. The most important biological role of carnitine is its participation in the metabolism of fatty acids and the production of energy.
Due to the significant role of carnitine in the oxidation of fatty acids and the production of cellular energy, L-Carnitine supplements are often chosen by athletes as part of the design of sports nutrition programs.
Acetyl L-carnitine is the acetylated form of L-carnitine and is characterized by increased absorption and bioavailability. Most clinical studies concerning carnitine have been conducted using this form.
