Glutathione precursors blend

Tier 3 — weak evidence · Antioxidant · Detox

Combines NAC, glycine, and selenium to supply raw materials for glutathione production — the body's master antioxidant. This approach is more effective and affordable than direct oral glutathione, which is poorly absorbed. Each ingredient has independent clinical evidence. A 2021 RCT found GlyNAC supplementation significantly improved glutathione deficiency in older adults.

Dose: 600 mg NAC + 3 g glycine + 100 mcg selenium daily; may be more effective than direct glutathione
