NAC 600mg by Pure Encapsulations

If your Glutathione test (blood or RBC glutathione, the body’s master antioxidant) is low or you live with high pollution, heavy training, or frequent travel, NAC 600 mg is a practical way to replenish reserves. It’s also useful when liver markers like ALT, AST, or GGT run higher than you’d like from lifestyle factors. Vegans on restrictive diets, who often get fewer sulfur amino acids, and people bothered by thick seasonal mucus tend to notice the most day‑to‑day difference. If you’re chasing big respiratory changes, higher or divided dosing is usually what’s studied.

NAC (N‑acetylcysteine) supplies cysteine, the rate‑limiting building block your cells use to make glutathione. More glutathione improves how cells neutralize oxidants and recycle other antioxidants. NAC also breaks disulfide bonds, which makes thick mucus less sticky and easier to clear. In clinical studies, NAC can nudge inflammation markers like hs‑CRP (high‑sensitivity C‑reactive protein, a general inflammation signal) down in responders and may improve redox status within 2 to 6 weeks. It’s not a cure for infection, but it often helps the terrain.

Take one 600 mg capsule between meals, one to three times daily. Most adults do well starting once daily for a week, then adding a second dose if targeting mucus or low glutathione; a third dose is a short‑term option. You can take NAC with a small snack if it upsets your stomach. Expect glutathione changes on labs within 2 to 6 weeks, and mucus effects within days. Pairing NAC with glycine or vitamin C is common in practice.

NAC can amplify the blood‑pressure‑lowering and headache effects of nitroglycerin; avoid that combo unless your prescriber approves. If you use warfarin or antiplatelet drugs, monitor more closely—rare reports suggest NAC can influence clotting tests. Active stomach ulcers or severe reflux can flare with NAC’s acidity. Pregnancy and breastfeeding: talk with your clinician first. If your liver enzymes are significantly elevated, get evaluated rather than self‑treating with NAC.
