Can a simple pill help your lungs, liver, and brain?

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.
Surprising Findings
NAC works for schizophrenia and addiction — not because it’s an antioxidant, but because it modulates glutamate, a brain chemical linked to mental health.
People assume it’s just a 'liver pill' — but it’s actually a brain modulator, which is a totally unexpected mechanism for a decades-old drug.
Practical Takeaways
Keep NAC in your medicine cabinet if you or someone you know takes Tylenol regularly — especially if there’s risk of accidental overdose.

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.
