€0.32 per serving with three synergistic active compounds is attractive.

Product quality 8.0/10

Setria glutathione, pharmaceutical-grade cysteine, and ascorbic acid produced under GMP conditions.

Label honesty 8.0/10

All amounts clearly listed, including excipients.

Third-party testing 7.0/10

Product Description

Each capsule contains 100 mg reduced glutathione (Setria), 500 mg L-cysteine, and 500 mg vitamin C. The combination targets a stable redox balance and supports endogenous glutathione synthesis.

What We Like

  • Setria branded ingredient with documented bioavailability
  • Combines precursor (cysteine) and cofactor (vitamin C)
  • 100 servings last over three months
  • Free of magnesium stearate

What We’re Missing

  • No liposomal delivery form
  • Capsules contain gelatin

Usage Recommendation

1 capsule with a morning meal. Under increased oxidative load, add a second capsule in the afternoon and drink plenty of water.
