More information
NAC is a sulfur-containing derivative of the amino acid L-cysteine, which supports antioxidant and detoxification mechanisms in the body and is a free radical scavenger. NAC supports antioxidant activity by neutralizing hydrogen peroxide, hypochlorous acid, and the highly reactive hydroxyl radical. It also serves as a source of sulfhydryl groups. NAC enhances the production of the tripeptide glutathione, a key component of both antioxidant and detoxification enzymes [1].
NAC is recognized for its support of normal mucous production and may positively support respiratory function and eye health, especially when consumed over a prolonged period [1-3]. Research suggests that NAC may protect cell and tissue health by supporting normal metal status in the body [1,4,5].
Glutathione: While the absorption of oral glutathione may be limited [6], supplementation with NAC may significantly increase circulating levels of glutathione in the body [7,8]. Glutathione also participates in fatty acid synthesis and amino acid transport across the cell membrane [1].
A variety of factors may determine glutathione requirements, including level of exposure to toxins, increased phase I detoxification activity, and overall need for antioxidant support. Glutathione supports the detoxification of environmental toxins and heavy metals. Maintaining glutathione levels may be important to maintaining the health of the respiratory, hepatic, and immune systems, as well as supporting antioxidant protection of lipids and proteins and supporting the normal response to inflammation [7,8,9]. Levels of endogenous antioxidants, including glutathione, may decrease with age [10].
CAUTION: If you have issues with sulphur you may NOT want to use this product.
