NAC-

A targeted 3-in-1 formula designed to support glutathione production, cellular antioxidant defenses, and normal sulfur metabolism.

 Supports healthy respiratory function and the body's natural mucus-clearing processes NAC → cysteine availability → glutathione production → cellular antioxidant defense NAC is an acetylated derivative of cysteine and is well established as a precursor to glutathione. Glutathione participates in antioxidant defense throughout the body, and NAC can help replenish cysteine availability needed to produce it. Reviews of the research describe both glutathione-related antioxidant activity and NAC's ability to break disulfide bonds in mucus Selenium isn't merely another random antioxidant. Selenium is incorporated into glutathione peroxidases, enzymes that use glutathione as part of the body's antioxidant-defense system. Selenium-containing proteins are also involved in thyroid hormone metabolism, DNA synthesis, reproduction, and protection from oxidative damage. NAC helps supply building material for glutathione, while selenium supports glutathione-dependent antioxidant enzymes. Molybdenum is required for four recognized human enzymes, including sulfite oxidase, which participates in normal sulfur metabolism. NIH describes it as an essential trace element required for sulfite oxidase, xanthine oxidase, aldehyde oxidase, and mARC. Supports antioxidant enzyme activity, provides essential selenium for normal immune function and supports normal thyroid hormone metabolism.
