L-lysine is an essential amino acid with important functions for the body. Its main characteristics include:

• Support of the immune system.
• Support of a healthy cardiovascular system.
• Absorption of calcium, increasing its availability for biological functions.

Lysine is essential for growth, lean body mass, and the management of nitrogen stores in the body. Acting as a precursor for other amino acids, such as L-citrulline and L-carnitine, it contributes to the normal metabolism of proteins and fats. Additionally, lysine is vital for the formation of collagen and ensures the absorption and retention of calcium, as it can reduce its excretion.

The conversion of lysine into acetyl-CoA provides energy through the Krebs cycle, while supporting the maintenance of nitrogen balance in the body. L-lysine is incorporated into many proteins, performing various roles within the body.
