L-Arginine is a conditionally essential basic amino acid involved primarily in urea metabolism and excretion, as well as in DNA synthesis and protein production. It is an important precursor of Nitric Oxide (NO) and thus plays a role in the dilation of blood vessels.

N-acetyl cysteine is a very efficient way to replenish glutathione, one of the body’s most potent antioxidants, and reduce the damaging effects of reactive oxygen species. NOW® has added the essential trace minerals of molybdenum and selenium to further enhance the antioxidant potential of this formulation.

Glutamine is involved in maintaining a positive nitrogen balance (an anabolic state) and acts as the primary fuel for rapidly growing cells (immune system and intestinal cells). In addition, Glutamine is also a major nitrogen transporter and helps to regulate the body’s acid-base balance.

Helps support immune system health after periods of physical stress and helps to assist in muscle cell repair after exercise.

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. In addition, L-Lysine supports a healthy immune system helping to fight cold sores.
