An antioxidant closely related to L-cysteine, being its acetyl derivative. Cysteine is important for homeostasis, being a key antioxidant, a glutathione precursor, and a natural source of sulfur for metabolism. Yet L-cysteine is unstable, and can become degraded while being absorbed. N-Acetyl Cysteine, on the other hand, is more stable than L-cysteine and conveniently becomes converted into L-cysteine after being absorbed. Thus NAC taken orally will raise blood and tissue cysteine levels. As a dietary supplement, NAC is therefore a highly attractive alternative to L-cysteine.
In our office we use NAC with GSH-Plus as a heavy metal chelator and for patients who have emphysema and other lung problems.
