Key Health Benefits

Benefit Area	Description of Clinical Trial Findings	PubMed Link
Respiratory health (COPD)	In a 1-year double-blind trial of stable COPD patients, high-dose NAC (600 mg twice daily) significantly improved small-airway function and reduced exacerbation frequency versus placebo.	PubMed (PMID: 23348146)
Liver health (NAFLD)	Among patients with nonalcoholic fatty liver disease, 3 months of NAC supplementation significantly lowered serum ALT (alanine aminotransferase) compared to an active control (vitamin C), indicating improved liver function.	PubMed (PMID: 22308119)
Kidney health (contrast nephropathy)	In acute myocardial infarction patients undergoing primary angioplasty, adding NAC (intravenous plus oral) markedly reduced contrast-induced acute kidney injury. The incidence of a ≥25% rise in serum creatinine was 33% in controls versus only 15% (standard NAC) and 8% (high-dose NAC).	PubMed (PMID: 16807414)
Immune support (influenza-like illness)	In a 6-month trial of elderly subjects, long-term NAC (600 mg twice daily) significantly attenuated influenza-like illness: NAC-treated subjects had fewer, less severe symptoms, and only 25% of NAC-treated infected individuals developed clinical illness versus 79% in the placebo group.	PubMed (PMID: 9230243)
Mental health (OCD)	In patients with treatment-resistant obsessive-compulsive disorder, adjunctive NAC (up to 2400 mg/day) significantly reduced OCD symptoms. By week 12, 52.6% of NAC-treated patients were full responders (≥35% Y-BOCS reduction) versus only 15% on placebo.	PubMed (PMID: 23131885)

What to Avoid

Substance	Reason to Avoid	Spacing Tip
Nitroglycerin & Nitrates	NAC can potentiate hypotensive effects of nitrates	Avoid concurrent use; consult your doctor
Activated Charcoal	May adsorb and reduce NAC absorption	Space by ≥2 hours between doses
Heavy Metal Exposures	NAC may chelate metals, altering pharmacokinetics	Monitor levels if on metal-based therapies
High-Fat Meals	May slow NAC absorption	Take NAC 30 min before or 2 h after meals
