N-Acetyl-Cysteine (NAC) 600mg
Cysteine amino acid and glutathione precursor. People take it for:
- Glutathione and antioxidant support
- Thinner mucus, mostly shown in lab models
- Lung support in conditions like COPD
Why it works
People take it as a glutathione precursor with antioxidant properties, and for thinner mucus. Given by IV it is well established after acetaminophen overdose, while evidence for cystic fibrosis is mixed and COPD studies point to fewer flare-ups. Absorption by mouth is low, and studies using under about 1,200 mg a day may show little effect.
