Lysine (L-Lysine)

L-lysine is one of the 9 essential amino acids the body can’t make on its own. You need amino acids like L-lysine for healthy muscles and tissues, but L-lysine may also help your body produce immune cells, speed up muscle recovery, and block stress response receptors. Since stress weakens the immune system, L-lysine supplements support immune health from more than one angle.
