Overview

Nutricost NAC provides 600mg of N-acetyl L-cysteine per capsule. NAC is the most effective oral precursor to glutathione — the body's master antioxidant that protects every cell from oxidative damage. NAC replenishes intracellular glutathione by providing the rate-limiting amino acid cysteine in a stable, bioavailable form. Clinical applications include liver protection (acetaminophen overdose treatment in hospitals), respiratory health (mucolytic — thins mucus), mental health (OCD, addiction support), and general antioxidant defense. The 180-capsule count provides a 6-month supply at one capsule daily or 3 months at the common 1200mg/day dose.
