NAC for Histamine Intolerance, Mast Cell Activation, and Hormone-Related Inflammation N-acetylcysteine (NAC) is a precursor to glutathione, one of the bodys most important antioxidants involved in immune regulation and detoxification
Although the drop in hepatic or renal GSH is the most toxicologically relevant interaction (see also below), plasma GSH, free cysteine (Burgunder et al., 1989), and antioxidant capacity (Nuttall et al., 2003) were significantly reduced after a single 2 g PAC administration or 14 days of therapeutic doses of PAC in human volunteers, respectively
Liposomal glutathione is built to work around that the active ingredient is coated in a phospholipid layer, essentially a fat-based shell, designed to protect it through digestion
