Lysine

Lysine is an essential amino acid that your body doesn’t produce on its own, which means it must come from diet or supplementation. Primary dietary sources of lysine are meat, poultry, fish, dairy, tofu, lentils, and beans. However, because many individuals don’t get enough lysine through diet alone, supplementation of this essential amino acid is advisable.
Thorne’s Lysine uses the purest, most absorbable form of this amino acid – without adding unnecessary additives or preservatives.
