NAC makes up Glutathione, a critical antioxidant scientifically proven to scavenge free radicals. NAC has the unique ability to maintain healthy lung tissue, support the body's natural defenses and enhance cellular health and longevity. These qualities make NAC especially beneficial for active people, the elderly and those exposed to polluted environments.

What makes NAC so effective as a glutathione booster is the fact that it is a stable amino acid that can retain up to six times the amount of the sulfur and sulfhydryl groups after digestion. Scientists believe that sulfur and sulfur compounds may be central to glutathione. This is crucial for the body's life functions, as NAC helps the body neutralize toxins, heavy metals, such as mercury from dental amalgam fillings, cadmium and lead from paint and cigarette smoke. The Sulfhydryl balance has also been linked to enhance resistance to viral infections.

N-Acetyl-L-Cysteine (NAC) provides powerful immune support and also packs a powerful anti-toxin potential. N-Acetyl-L-Cysteine has the ability to neutralize cell and DNA damaging free radicals.

NAC has been shown to play a protective role against a variety of toxic hazards such as cigarette smoke, auto exhaust, certain herbicides, and overdoses of acetaminophen. It can also play a beneficial role in prostate and respiratory conditions. For example, NAC has well established anti-mucolytic (anti-mucous) properties and has been shown to increase mucocilary transport in smokers.
