N-Acetyl-L-Cysteine (NAC) 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.

NAC is the dietary supplement of choice for supporting the body’s stores of glutathione, cysteine, and other sulfhydryl antioxidants.* Oral supplementation with glutathione appears not to be the best means for repleting the body’s glutathione levels, since it is largely broken down by intestinal enzymes and comparatively little is absorbed intact. NAC, on the other hand, appears to be an excellent dietary starting substance for building up reduced glutathione.
NAC is well-tolerated, well-absorbed, resists enzymatic breakdown, and has been proven to raise internal GSH and cysteine levels when administered orally.* NAC is also more stable than its non-acetylated relative L-cysteine, which has a tendency to “auto-oxidize” (break down spontaneously).
