Overview
This is an N-Acetyl Cysteine (NAC) capsule supplement from Deal Supplement, delivering 1,000 mg of NAC per serving alongside reduced glutathione, sold in a 240 capsule count aimed at antioxidant, immune, lung and liver support.
NAC is a precursor the body uses to make glutathione, one of its main internal antioxidants, and this formula pairs the two directly rather than relying on NAC alone to convert. At 240 capsules it is built for extended daily use rather than a short trial.
- 1,000 mg NAC per serving
- Reduced glutathione included
- 240 capsules
- Vegan, gluten-free
Who it's for
Suited to people looking for an ongoing antioxidant supplement stack rather than a short course, and to anyone who prefers a vegan, gluten-free capsule format. Not the right fit for someone who wants a lower per-serving dose or an easy-swallow softgel instead of a standard capsule.
Strengths and trade-offs
Drawn from this product's published specifications.
- 1,000 mg NAC per serving plus added glutathione
- Large 240 capsule count
- Vegan and gluten-free
- Unflavored capsule, no alternative format offered
- No description or attribute detail on additional ingredients
- High capsule count is a large upfront commitment if untested
Performance notes
Pairing NAC with reduced glutathione in one capsule means you are not relying solely on the body's own conversion of NAC into glutathione, which is the usual bottleneck with NAC-only formulas.
