Our highest NAC dose -1300mg per capsule -for those who need meaningful glutathione precursor support for liver health, respiratory comfort, and antioxidant defense.
Why It Works
Why NAC Is the Most Direct Route to Raising Glutathione
Direct Glutathione Precursor
NAC (N-Acetyl Cysteine) is converted in the body to cysteine, the rate-limiting amino acid in glutathione synthesis. Supplementing NAC is one of the most reliably studied ways to raise intracellular glutathione levels.
Liver Detoxification Support
Glutathione is the liver's primary antioxidant and detoxification cofactor. Higher NAC doses at 1300mg are used clinically in research contexts to support liver function and protect hepatocytes from oxidative burden.
Respiratory Mucosal Support
NAC has a well-documented mucolytic effect -it breaks down disulfide bonds in mucus, helping maintain healthy airway clearance. This is why pharmaceutical-grade NAC is used in respiratory medicine worldwide.
Immune Cell Protection
Immune cells are especially vulnerable to oxidative damage. Adequate glutathione, fueled by NAC, helps protect immune cells and supports the maintenance of robust immune function under stress.
Mental Clarity & Mood Balance
Emerging research links NAC to glutamate regulation and oxidative stress reduction in the brain. Some studies have explored its role in supporting mood stability, though this is an active area of research.
High Dose for Those Who Need It
At 1300mg per capsule, this is our maximum-strength NAC formulation -suited for adults who have previously used lower doses and want to step up, or those under significant oxidative or respiratory load.
Glutathione Uplift
NAC vs. Placebo: Measured Glutathione Response
Unlike taking glutathione directly -which is largely degraded in the gut -NAC is efficiently absorbed and converted intracellularly. Published RCT data shows meaningful glutathione uplift with NAC supplementation that oral glutathione cannot reliably match.

Your Journey
What to Expect Over 3 Months
Foundation
Month 1
In the first 2–4 weeks, many users notice improved respiratory comfort -less morning congestion and easier breathing. The liver begins benefiting from increased glutathione availability, which supports the natural daily detox cycle.
At 1300mg, the dose is meaningful from day one, though full intracellular glutathione replenishment takes several weeks of consistent use.
