How a simple chemical helps your body fight damage
The role N-acetylcysteine (nac) in the therapy of diseases characterized by oxidative stress (literature review)

N-acetylcysteine is a substance your body uses to make a protective molecule called glutathione. It's been used for years to thin mucus and fix liver damage from too much acetaminophen. Now doctors are trying it for new problems in organs like the brain, eyes, and transplanted organs.
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.
N-acetylcysteine is a supplement that helps your body make more of a natural antioxidant called glutathione, which protects your cells. Doctors are now using it more often to help patients after transplants, with brain conditions, and with eye diseases because they understand better how it works.
N-acetylcysteine is a medicine that’s been used for years to thin out thick mucus in your lungs by breaking the sticky glue-like strands in it, making it easier to cough up.
When someone takes too much acetaminophen (like Tylenol), it can damage the liver—but N-acetylcysteine (a medicine given in hospitals) helps the liver clean up the poison by restoring a natural protective chemical called glutathione.
