    What to know

    NAC is a form of the amino acid cysteine, which the body uses to make glutathione, an antioxidant found inside cells. Glutathione taken by mouth is partly broken down in digestion, which is why many people choose NAC instead. NAC has a natural sulfur smell, which is normal. If you pick the version with selenium, count it with any other selenium you take and stay at or under 150 mcg a day from supplements.
