Tripeptide Antioxidant
Glutathione
Master Antioxidant Tripeptide
Glutathione is the body's primary natural antioxidant, a small peptide found in every cell. It is researched for how it neutralizes free radicals, supports the liver's detox pathways, and keeps cells in chemical balance. It is also studied in skin-brightening research.

Overview
Glutathione (GSH) is a naturally occurring antioxidant tripeptide with the sequence gamma-Glu-Cys-Gly and the molecular formula C10H17N3O6S. In the research literature it is one of the most widely referenced redox-active molecules, studied in models of oxidative-stress balance, cellular detoxification pathways, and thiol chemistry. VANTA supplies glutathione as a lyophilized reference material so laboratories can incorporate a characterized, traceable tripeptide into in-vitro and preclinical work. All material is provided strictly for research use only.
Researchers reference the glutathione peptide as a model compound across several investigative areas, including redox-balance research, detoxification-signaling research, and melanin and pigmentation-pathway research in cultured-cell and tissue systems. Its cysteine thiol group is central to how the molecule is characterized in published work, which is why analytical certainty about identity and purity is a frequent focus. Because results can be confounded by oxidation products and impurities, VANTA positions its research grade glutathione as a verified reference standard rather than a generic powder.
Each lot of glutathione for sale through VANTA is screened by reversed-phase HPLC for chromatographic purity and confirmed by mass spectrometry for identity against the expected tripeptide mass. This pairing lets researchers attribute observed effects in their models to glutathione itself rather than to contaminants or degradation byproducts. Laboratories that buy glutathione from VANTA receive a per-batch Certificate of Analysis tied to the exact vial in hand, supporting reproducible, well-documented experimental work.
Research Areas
Handling & Reconstitution
Glutathione is supplied as a lyophilized powder and should be stored sealed at -20C and protected from light to limit oxidation of its cysteine thiol. Researchers typically reconstitute the sealed vial with an appropriate solvent immediately before laboratory use, following their own institutional protocols, and minimize freeze-thaw cycles and ambient exposure to preserve peptide integrity for reproducible in-vitro work.
Frequently asked questions
What is glutathione?
Glutathione (GSH) is a naturally occurring antioxidant tripeptide with the sequence gamma-Glu-Cys-Gly and molecular formula C10H17N3O6S. In the research literature it is studied as a model redox-active molecule and reference compound for in-vitro and preclinical work. VANTA supplies it strictly as a laboratory research material.
What form and purity is this glutathione peptide?
VANTA glutathione is supplied as a lyophilized powder. Each lot is assessed by reversed-phase HPLC for chromatographic purity, with a specification targeting high purity near 99%, and confirmed by mass spectrometry against the expected tripeptide mass so researchers work from a characterized reference standard.
How should research grade glutathione be stored and reconstituted?
Store the sealed lyophilized vial at -20C and protect it from light to limit thiol oxidation. Researchers generally reconstitute with an appropriate solvent immediately before use, following their own institutional protocols, and avoid repeated freeze-thaw cycles to maintain peptide integrity for reproducible experiments.
Is each batch third-party tested with a COA?
Yes. Every glutathione lot ships with a per-batch Certificate of Analysis documenting the HPLC purity result and the mass-spectrometry identity confirmation for that specific lot. This lets a laboratory tie each experiment to a traceable batch and its supporting analytical data.
What research areas is glutathione studied in?
In published literature the glutathione peptide is referenced across redox-balance, cellular-detoxification, and melanin and pigmentation-pathway research in cultured-cell and tissue models. These are descriptions of how the molecule is examined in laboratory systems, not statements about any outcome in humans.
Is glutathione intended for human use?
No. VANTA glutathione is sold strictly for laboratory and in-vitro research use only by qualified professionals. It is not a drug, supplement, or food, is not for human or veterinary consumption, and nothing here is medical advice or a claim of any therapeutic, diagnostic, or health effect.
