N-Acetyl Cysteine (NAC)


Principal Proposed Uses

Other Proposed Uses

N-acetyl cysteine (NAC) is a specially modified form of the dietary amino acid cysteine. When taken orally, NAC is thought to help the body make the important antioxidant enzyme glutathione. It has shown promise for a number of conditions, especially chronic bronchitis.


There is no daily requirement for NAC, and it is not found in food.

Therapeutic Dosages

Optimal levels of NAC have not been determined. The amount used in studies has varied from 250 to 1,500 mg daily. It has been suggested that NAC may increase excretion of trace minerals; some evidence, however, suggests that this effect is too minimal to make a real difference. 47 Prudence suggests that individuals taking NAC for an extended period of time should also consider taking a standard multivitamin/multimineral supplement.
