N-Acetyl Cysteine (NAC) is a potent antioxidant and cell detoxifier. It is derived from the amino acid L-Cysteine, and plays an important role in the production of glutathione, the body's primary antioxidant that's crucial in the fight to neutralize free radicals and to detoxify harmful agents from the body*.

The primary function of N-Acetyl Cysteine is in the production of glutathione. Glutathione is a small protein found inside cells that plays an important role in the body’s antioxidant defense system. N-Acetyl Cysteine is quickly metabolized into glutathione once it enters the body. Glutathione then functions as a powerful antioxidant and cell detoxifier. As an antioxidant, glutathione effectively scavenges free radicals, neutralizing their harmful effects upon cells. As a detoxifier, glutathione can alter chemicals so that they become less harmful.

Glutathione enhances the immune system by aiding the transport of important nutrients to immune cells called lymphocytes and phagocytes, as well as helping to strengthen cell membranes. Glutathione's other benefits include promoting the manufacture of new muscle mass and maintenance of RNA and DNA.
