NAC 1000mg delivers meaningful glutathione precursor support in a single daily capsule -the middle-ground dose for those who want more than 600mg without stepping up to 1300mg.
Why It Works
Why 1000mg Hits the Sweet Spot for Daily NAC Use
One Capsule, One Meaningful Dose
At 1000mg, a single capsule delivers approximately the same total NAC as 1–2 lower-dose capsules combined. This simplifies your routine -one capsule with breakfast, and you're covered for the day.
Reliable Glutathione Precursor
NAC is converted intracellularly to cysteine -the rate-limiting building block for glutathione synthesis. At 1000mg, this precursor activity is robust enough to support measurable glutathione uplift with daily use.
Liver Health at a Practical Dose
Liver detoxification pathways depend heavily on glutathione. 1000mg of NAC daily supports the liver's capacity to process everyday metabolic waste and environmental exposures without the intensity of the 1300mg maximum-dose option.
Respiratory Comfort
NAC's mucolytic and airway-support properties are well-expressed at 1000mg. It helps maintain comfortable, clear breathing and supports the mucosal lining of the respiratory tract against environmental stressors.
Immune Antioxidant Defense
Immune cells require adequate glutathione to function properly and resist oxidative damage. NAC at 1000mg supports consistent immune cell protection as part of a daily antioxidant stack.
Large 240-Count Supply
With 240 capsules at one per day, this bottle lasts 8 months -or over 4 months at two capsules per day. A serious long-term supply for those committed to consistent NAC use.
Glutathione Uplift
NAC vs. Placebo: Measured Glutathione Response
NAC is absorbed intact and converted intracellularly, raising glutathione where it is needed. At 1000mg daily (approaching the 1200mg dose shown in published RCTs), glutathione uplift is consistent and meaningful.

Your Journey
What to Expect Over 3 Months
Foundation
Month 1
In the first 2–3 weeks at 1000mg daily, most users notice improved respiratory clarity and a steadier feeling of antioxidant resilience. At this dose, effects are typically a step up from the 600mg experience -enough NAC in a single capsule to meaningfully support glutathione pathways without needing to double up.
