Glutathione (GSH) is a naturally occurring tripeptide composed of glutamic acid, cysteine, and glycine, joined by a distinctive γ-glutamyl linkage that confers resistance to peptidase degradation. It is the most abundant intracellular antioxidant in mammalian cells, existing in reduced (GSH) and oxidised (GSSG) forms — the ratio between them serving as a widely used indicator of cellular oxidative stress in research.
In research contexts, glutathione is studied for its role in neutralising reactive oxygen species, in the regeneration of other antioxidants, and in phase II detoxification through conjugation reactions catalysed by glutathione S-transferases. It is supplied by Vital Research Labs strictly as a reference compound for in-vitro laboratory investigation.
Research context
- Redox homeostasis — the GSH/GSSG ratio is a standard marker of cellular oxidative state in laboratory models.
- Detoxification pathways — studied as a substrate in glutathione S-transferase-catalysed conjugation.
- Antioxidant enzyme systems — investigated as a substrate for glutathione peroxidase.

Reconstitution & handling
Glutathione is supplied as a lyophilised (freeze-dried) powder. For research handling it is typically reconstituted with bacteriostatic water; the exact volume depends on the concentration a given research protocol calls for. Our reconstitution calculator can be used to work out volumes for a target research concentration. Handle under appropriate laboratory conditions and avoid repeated freeze–thaw cycles of the reconstituted solution.
Storage & stability
- Lyophilised powder — store at -20 °C, protected from light and moisture.
- Reconstituted solution — store at 2–8 °C and use within 28 days.
- Oxidation-sensitive — glutathione is readily oxidised; protect from light and air, and minimise freeze–thaw cycles.
Quality & testing
Every batch supplied by Vital Research Labs is analysed by an independent third-party laboratory. Purity is confirmed by high-performance liquid chromatography (HPLC) and identity by mass spectrometry (MS). The Certificate of Analysis for this batch is published in our CoA library once received.
Shipping within Australia
Glutathione is dispatched from within Australia to Australian research customers, packaged discreetly and appropriately for a lyophilised research compound. Orders are processed on receipt of payment via bank transfer.
Frequently asked questions
Is Glutathione available in Australia for research?
Yes. Vital Research Labs supplies research-grade Glutathione (1500mg) to Australian research customers, dispatched domestically. It is provided strictly for in-vitro laboratory research and is not for human or veterinary use.
What purity is your Glutathione?
This batch is verified at 98.391% purity by third-party analytical testing (HPLC for purity, mass spectrometry for identity). The Certificate of Analysis for batch CS-Glu1500-2223 is published in our CoA library.
How is Glutathione tested?
Each batch is analysed by an independent third-party laboratory using HPLC to confirm purity and mass spectrometry to confirm identity. Batch-specific values are recorded on the Certificate of Analysis once testing is complete.
How should Glutathione be stored?
The lyophilised powder is stored at -20 degrees C, protected from light and moisture. Once reconstituted for research it is kept at 2-8 degrees C and typically used within 28 days. Glutathione is oxidation-sensitive, so protection from light is important.
Is Glutathione intended for human use?
No. Glutathione (1500mg) supplied by Vital Research Labs is intended strictly for in-vitro laboratory research and development. It is not a medicine or therapeutic good and is not for human consumption, veterinary use, or clinical application.
