NOW NAC 600mg is a 100-capsule supplement of N-acetyl cysteine, a precursor to glutathione, the body's main antioxidant. Each capsule delivers 600mg of NAC plus selenium, and the formula is rounded out with L-cysteine, L-glutamine and L-arginine. It is gluten free and marketed for liver, immune, respiratory and hair support. It suits people who want a single high-dose NAC capsule rather than a lower-dose or combination product, though the added amino acids are modest amounts and the evidence for hair and respiratory claims is thinner than for glutathione support.

Owners of NOW NAC generally report it as a reliable, affordable NAC capsule that is easy to add to a daily routine. Complaints center on the sulfur smell and on capsule size rather than on effectiveness.
