Lysine is one of the most abundant amino acids in the body, with anywhere from a pound to a pound and a half in the average person. Lysine is an essential amino acid which means the body does not metabolize it on its own; it has to come from an exogenous source. It is a key building block of collagen and, with the amino acid proline, makes up to a third of the body’s connective tissue (ligaments, tendons) of which 80% is collagen. Lysine promotes bone, skin and cartilage formation and is required for the proper functioning of joints. Lysine also has immune boosting and antiviral benefits. Our L Lysine formula is nano sized so that the nutrient can bypass the digestive tract when combined with a simple sugar molecule, this means real absorption and real benefits.
