NAC 500 mg 120 tabs New Size Same Price! An antioxidant closely related to L-Cysteine, being its acetyl derivative. Cysteine is important for homeostatsis, 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. Ingredients: N-acetylcysteine 500 mg Suggested Use: 1 tablets 2-3 times daily.
