How L-lysine works
L-Lysine is an essential amino acid.
It functions by serving as a building block for protein synthesis, which is vital for growth, healing and maintenance of tissues in the body.
L-Lysine is particularly significant in the production of collagen, a key structural protein in skin, bones and connective tissues.
Additionally, L-Lysine may inhibit the replication of the Herpes simplex virus (HSV), potentially reducing the severity and duration of cold sores.
