Overview
This GlyNAC complex combines glycine and N-acetylcysteine (NAC) in a large 1600 mg tablet, formulated around glutathione production for healthy aging and cognitive support. It comes in a glass bottle, is made in the USA, gluten free, non-GMO, and the listing states it is third-party tested.
Glycine and NAC together are precursors the body uses to synthesize glutathione, one of its primary internal antioxidants, and pairing them in a single combination product is the basis of the GlyNAC approach referenced in aging research. The 1600 mg tablet size is notably large, which the listing itself flags, worth knowing before ordering if swallowing large tablets is a concern.
- Glycine and NAC combination tablet
- 1600 mg large-size tablet
- Third-party tested, USA made
- Glass bottle, gluten free, non-GMO
Who it's for
Fits someone specifically looking for a combined glycine and NAC product built around the glutathione pathway, packaged in glass rather than plastic and made in the USA. Not a fit for anyone who has difficulty swallowing large tablets, since 1600 mg tablets are explicitly called out as large in the product name.
Strengths and trade-offs
Drawn from this product's published specifications.
- Combines glycine and NAC in one tablet
- Third-party tested per the listing
- USA made in a glass bottle
- Gluten free and non-GMO
- Large 1600 mg tablets may be hard to swallow for some
- 120 count bottle at one tablet per serving is a modest supply if dosed higher
- No flavor masking, unflavored
Performance notes
Glycine and NAC are combined because together they supply the building blocks the body needs to produce glutathione internally, rather than supplying glutathione directly, which is poorly absorbed when taken as a standalone supplement. The formula is positioned toward aging and cognitive support based on that glutathione-production mechanism.
