Glutathione — LifeSource VitaminsGlutathione — Capsules — Cellular Antioxidant Support*
LifeSource Vitamins Glutathione features reduced L-glutathione (GSH), the body’s primary intracellular antioxidant. Each formula is designed to support cellular antioxidant health, promote redox balance, aid in vitamin C & E regeneration, and assist normal detoxification pathways—enhancing cellular resilience and immune function. Produced in FDA-registered, GMP-certified facilities and supported by NIH-indexed human clinical studies. Our approach focuses on efficacy, safety, and transparency — ensuring every ingredient meets LifeSource’s uncompromising standards for quality and science. Non-GMO.*
Research Promise. Every benefit listed is backed by human clinical studies indexed in the National Institutes of Health (NIH) via PubMed, with full texts available in the National Library of Medicine (PMC) when available. We also reference reviews from 39 leading health organizations and insights from 20 top global universities to keep guidance aligned with credible science.*
Clinically Studied Benefits
-
Supports glutathione levels* — Oral GSH (250–1,000 mg/day, 6 months) increased glutathione in blood and red blood cells, declining after washout. (NIH/PubMed — Richie JP Jr, 2015)
-
Supports immune function* — Same trial noted over 2-fold gains in natural killer (NK) cell activity at higher doses. (NIH/PubMed — Richie JP Jr, 2015)
-
Supports antioxidant defense* — Liposomal GSH pilot increased blood glutathione and altered immune/cytokine markers vs placebo. (NIH/PMC — Sinha R, 2018)
-
Supports cellular redox balance* — Reviews outline glutathione’s central role in antioxidant systems. (NIH/PMC — Forman HJ, 2009)
-
Supports vitamin C & E regeneration* — Glutathione participates in regenerating other antioxidants. (NIH/PMC — Pizzorno J, 2014)
