L-Lysine is one of the 9 essential amino acids. The body needs it for proper growth and tissue repair, and children need is 3-4 times higher than in adults. Benefits: Assists the production of enzymes, hormones, and antibodies Stimulates healthy immune system An essential amino acid for growth and repair of tissues An important component for the formation of collagen Participates in calcium absorption It is a building block of proteins and affects the production of enzymes, hormones, antibodies, and collagen. L-Lysine is involved in the absorption of calcium. It is essential for bones and teeth. L-Lysine, together with Methionine is the raw material for the synthesis of carnitine, stimulating the formation of fatty acids at the cellular level. It is considered that Lysine has a positive effect on the treatment of herpes simplex virus (HSV). The analysis shows that HSV requires arginine for replication. L- Lysine competes with arginine for absorption by the body. In there is Lysine, it removes arginine and this way prevents the growth of HSV.
