N-Acetyl-L-Cysteine, also known as NAC, is a more stable form of the amino acid L-Cysteine and is the most effective way to boost Glutathione levels in the body. NAC is a more stable form of L-Cysteine because it has an acetyl group (CH3CO) attached. NAC has all the properties of L-Cysteine but is more water soluble and said to be more bioavailable than L-Cysteine.

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 defences 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 sulphur and sulfhydryl groups after digestion. Scientists believe that sulphur and sulphur compounds may be central to glutathione. This is crucial for the body's life functions, as NAC helps the body neutralise 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 enhanced 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 neutralise 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 paracetamol. 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 mucociliary transport in smokers.
