N-acetyl-cysteine (NAC) FAQ

Q: What Is NAC?
A: NAC stands for N-acetyl-cysteine. This sulfur-based amino acid N-acetyl-cysteine (NAC) is a specially modified form of the dietary amino acid cysteine. When taken orally, NAC helps make glutathione, one of the body's most important antioxidant enzymes. NAC has been shown to support lung and bronchial health.* NAC can also be used as an adjunct in helping to reduce homocysteine levels, which is important for heart health.*

Q: I'm allergic to sulfa drugs, can I still take NAC?
A: Sulfa drugs and the nutrient sulfur are not the same. Sulfa drugs are used to treat bacterial infections. On the other hand, sulfur is a natural nutrient found in every living cell and is part of the molecules that form amino acids. Sulfur is also found in many foods including egg yolks, broccoli, onions, and garlic.
