Overview
This is a combination capsule pairing Setria L-glutathione (reduced form) with L-cysteine hydrochloride and 500 mg of vitamin C, positioned as an antioxidant formula that supports the body's own glutathione production. It comes in a 100-capsule bottle, gluten free and non-GMO, aimed at a liver-support or general antioxidant regimen rather than a specific condition.
Reduced glutathione is difficult for the body to absorb intact when swallowed, which is likely why this formula leans on cysteine, a glutathione precursor, and vitamin C alongside the glutathione itself rather than glutathione alone. Setria is a licensed, patented glutathione ingredient, worth knowing if you compare label sourcing across brands.
- Setria L-glutathione (reduced form)
- 500 mg vitamin C per serving
- 100 capsules, gluten free
- Non-GMO formula
Who it's for
Suits someone already building a liver-support or antioxidant stack who wants glutathione, cysteine and vitamin C combined in one capsule instead of three separate bottles. Not a fit for anyone expecting a fast or noticeable effect, since antioxidant supplementation is a slow-build category.
Pros and cons
- Combines glutathione, cysteine and vitamin C in one capsule
- Uses branded Setria reduced glutathione
- Gluten free and non-GMO
- 100 capsules, about three months at one daily
- No individual ingredient amounts listed beyond the 500 mg vitamin C
- Capsule only, no powder or liquid option
Performance notes
The formula's logic rests on giving the body cysteine and vitamin C alongside preformed glutathione, since cysteine is the amino acid the body uses to synthesize its own glutathione and vitamin C helps regenerate the antioxidant once it's used. No individual dose split beyond the 500 mg vitamin C is stated, so anyone stacking with other cysteine or vitamin C products should account for total intake.
