N-Acetyl-L-Cysteine is a premier antioxidant, antitoxin, and immune support nutrient.* NAC is a derivative of the amino acid L-cysteine and is a dietary precursor to reduced glutathione. Glutathione, cysteine, and NAC are sulfhydryl (-SH) substances, which play crucial roles in the body’s natural antioxidant defenses.* Antioxidant activity is important to homeostasis and to normal metabolism.* NAC has superior bioavailability compared to glutathione and cysteine. As potent antioxidant free radical scavengers, the natural -SH substances can readily donate electrons, which makes them able to combine with, and thereby neutralize, a great variety of potentially toxic reactive substances.* These -SH substances can also help protect against radiation damage, which is largely mediated by free radical formation.* They are important physiological antitoxins and are valuable for optimal immune function.*
