NAC is a supplement that helps your body make a natural shield (glutathione) against damage. It helps fix liver damage from too much acetaminophen, reduces lung flare-ups in smokers with COPD, eases some symptoms of schizophrenia, and might protect eyesight in a rare eye disease.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

NAC is a supplement that helps your liver make more of a natural cleaning chemical called glutathione, which helps your body get rid of toxins.
If someone takes too much acetaminophen (like Tylenol), giving them NAC within the first 8–10 hours can save their liver by helping it fight off a poisonous byproduct; after 16 hours, it works much less well.
