Secondly, an unexpectedly dangerous compound to avoid is N-acetylcysteine (NAC), a high-priced product heavily recommended by alternative medical doctors and other health practitioners. NAC is a form of cysteine often recommended as a more powerful form of the much-needed amino acid L-cysteine or in lieu of glutathione, an antioxidant that is rarely effective in supplement form.66 Although dozens of journal articles support its short-term use as immunity booster and detoxifier, evidence is mounting of potential long-term harm. The NAC form of cysteine conceivably can poison vitalethine, a vital component needed to activate humoral immunity.67-69
