What is NAC and what does it do?

N-acetylcysteine (NAC), a sulfur-containing amino acid, is the precursor of the amino acids L-cysteine and glutathione. Animal and human studies of NAC show it to have powerful antioxidant activity.* In addition to antioxidant activity, NAC is effective in promoting normal liver detoxification.*

As a sulfur source, NAC stimulates glutathione (an important antioxidant produced in the body) synthesis and activity, promotes liver detoxification, and is a powerful molecule capable of scavenging free radicals.*

Research suggests NAC is capable of enhancing immunity.* In a double-blind, placebo-controlled trial, NAC was shown to positively impact lymphocyte cell numbers.*

NAC helps maintain good pulmonary health due to its mucolytic activity.* NAC’s sulfur cleaves bonds in mucoproteins, causing mucus to be subsequently broken into smaller, less viscous pieces.* NAC has been noted to decrease the viscoelasticity of nasal mucus and increase the clearance of mucus by the cilia by thinning of secretions, thus helping maintain good pulmonary health.*
