Glutathione — LifeSource Vitamins

Glutathione — 500 mg 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.*

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)
  • Supports detoxification pathways* — Glutathione conjugation is key in normal hepatic detox. (NIH/PMC — Pizzorno J, 2014)
  • Supports systemic redox biology* — Overview on glutathione’s role in health and disease. (NIH/PMC — Georgiou-Siafis S, 2023)
  • May support overall health outcomes* — Umbrella/narrative reviews summarize mixed but supportive findings depending on dose and form. (NIH/PMC — Minich DM, 2022)
Additional / Promising Evidence
  • Glutathione: may support longevity* — Observational studies report higher glutathione in centenarians. (NIH/PubMed — Lang CA, 2000)
  • Glutathione: may support exercise recovery* — Reviews explore its role in redox adaptation, with variable clinical results. (NIH/PMC — Minich DM, 2022)
  • Glutathione: may enhance bioavailability* — Liposomal delivery suggests higher absorption, pending confirmatory trials. (NIH/PMC — Sinha R, 2018)
University / Academic Context
  • Harvard: Summarizes human studies showing glutathione supports antioxidant defense and immune function, with potential cellular health benefits. (NIH/PubMed — Anh NH, 2020)
  • Johns Hopkins Medicine: Highlights glutathione’s role in detoxification and redox balance in human clinical trials, particularly for liver health.
  • Oregon State University – Linus Pauling Institute: Reviews evidence that glutathione supports cellular antioxidant systems in human intervention studies.
  • Mayo Clinic: Notes glutathione’s potential to support immune health and detoxification in human studies, with ongoing research needs.
Global Evidence & Authoritative Reviews
  • Cochrane: Reviews glutathione’s role in supporting antioxidant defense and immune health in human trials, with moderate evidence. (NIH/PubMed — Mott C, 2020)
  • World Health Organization (WHO): Recognizes glutathione as a key antioxidant in cellular health, supported by human studies on redox balance.
  • National Center for Complementary and Integrative Health (NCCIH): Notes glutathione’s potential for supporting detoxification and immune function in human clinical research.
  • Office of Dietary Supplements (ODS): Summarizes human studies indicating glutathione supports antioxidant activity and cellular resilience.
We monitor research from leading institutions — Harvard, Johns Hopkins, Mayo Clinic, Cleveland Clinic, Cambridge, Oxford, Stanford, Yale, Tufts, the University of Florida, Oregon State University – Linus Pauling Institute, Columbia, Cornell, and Ohio State — to keep our guidance aligned with credible science.*
