L-Cartinine is a non-essential amino acid that is synthesized by means of two other essential amino acids , lysine and methionine, and vitamin C. It is also found in many foods, especially meats (especially red), fish and dairy. This compound, which is formed in the kidneys and liver, plays a key role in fat metabolism.
Carnitine is essential for the fat burning process. This amino acid participates in the vascular circuit by reducing levels of triglycerides and cholesterol in the blood. It is involved in the transport of long-chain fatty acids into cells (mitochondria, which are the "ovens" of cells) and increases the speed of the energy generation process carried out in the liver from fat.
Long-chain fatty acids are the human body's natural energy store. They accumulate in adipose tissue and form fat. Due to their high molecular size, they cannot enter the mitochondria. In fact, the ability of each cell to burn fat is carnitine dependent.
