L-Lysine is an essential amino acid that must be obtained through the diet or through supplementation. Lysine is necessary for the production of all proteins in the body, and is required for the maintenance of the structural proteins collagen and elastin, which form all connective tissue such as skin, tendon, and bone. L-Lysine is also a precursor to L-carnitine, which is needed for fat metabolism and energy production. In addition, L-Lysine may help to support a healthy immune system and proper cardiovascular function.

NOW L-Lysine is Pharmaceutical Grade essential amino acid.

As recommended in science journals, I bought this for my husband who gets cold sores. It works to keep them from manifesting once he feels one coming on. He’s so happy!

Just what I needed

Since taking 1 tablet every second day I have not had a cold-sore for months (usually get them at least once a month minimum) it has also helped my overall immune system.
