LYSINE is an essential component of all proteins, working with other essential amino acids to maintain growth, lean body mass, and the body's store of nitrogen.
Being an essential amino acid, Lysine must be obtained through the diet or by supplementation (since your body cannot manufacture it.
Lysine acts as a precursor for several other amino acids, including L-Citrulline (needed for normal protein metabolism) and L-Carnitine (needed for fat metabolism).
Lysine is crucial for the formation of collagen, a major part of the body's connective tissues. It appears to help the body absorb and conserve calcium, possibly even reducing its excretion.
Lysine contributes to energy production when converted to acetyl coenzyme A, one of the principal fuels for the Krebs cycle.
Lysine is needed for growth and to help maintain nitrogen balance in the body. It also supports a healthy immune system.
L-lysine has many other functions in the body because it is incorporated into many proteins, which are used by the body for a variety of purposes.
