Richie et al. (Penn State Cancer Institute, Eur J Nutr, 2014, PMID 24791752) conducted the first long-term RCT of oral glutathione in 54 adults, finding 30–35% increases in erythrocyte and lymphocyte GSH at 1,000 mg/day over 6 months (p<0.05), challenging the long-held assumption that oral glutathione is fully degraded before absorption. This Ireland evidence guide covers glutathione's mechanism as the body's master antioxidant, the bioavailability debate, skin evidence, liver and detoxification research, dosage, safety, form comparison (reduced vs liposomal vs NAC), and NOW Foods Glutathione 500mg Veg Caps (60 caps, €24.95, 13.5% VAT included) — available with nationwide tracked delivery from Dublin under FSAI food supplement guidelines.
