Now L-Lysine is a Pharmaceutical Grade essential amino acid.

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.

Easy to take

Have been using this product along with L-Proline for quite a few years and feel it has helped me maintain good health. I take 4 capsules a day along with 3 capsules of Proline and 3 C-1000. It is a cellular medicine solution to heart disease.
