What is L-Carnitine?

L-carnitine is an amino acid, a vitamin-like substance, its characteristics are close to the vitamins of group B. It has anabolic and lipolytic effects. It is intended to stabilize the body’s metabolic processes and improve tissue energy supply.

L-carnitine plays a huge role in the metabolism of fats. It means that it helps turn fat into energy consumed by muscles and organs. As a result, it may increase exercise endurance and provide more oxygen to cells. This amino acid can also stimulate faster fat loss and help improve sports performance.

Some research has been successfully carried out on L-carnitine supplementation in athletes, patients with various cardiometabolic conditions, male infertility, cardiac ischemia, atherosclerosis, etc.

L-carnitine is a quaternary ammonium compound involved in metabolism in most mammals, plants, and some bacteria. L-carnitine supplement enhances protein synthesis and fatty acid transport to mitochondria.

In mitochondria, fatty acids are synthesized into energy. They are transported across the mitochondrial membrane to the cytoplasm of target cells such as the heart, brain, skeletal muscle, and other tissue cells, where they are needed as fuel.
