Glutathione UK — buying guide
What to check before you buy Glutathione (GSH) in the UK: the reduced antioxidant tripeptide, supplied as a characterised research reference standard.

What is Glutathione?
Glutathione (GSH) is a tripeptide composed of glutamic acid, cysteine and glycine, joined through an unusual gamma-glutamyl bond. It carries CAS number 70-18-8 and a molecular weight of 307.32, and is the most abundant low-molecular-weight thiol found inside living cells — a key substrate in redox and detoxification biochemistry.
In the laboratory glutathione is used as a reference standard in redox, antioxidant and cellular-energy research. Sova supplies it as a 1500mg research vial for controlled analytical work — not for human or veterinary use, and with no claim of any effect in people.
Before you buy
How to verify Glutathione before you buy
Glutathione oxidises readily, so what matters when buying is that the reduced GSH form is confirmed and quantified against the batch, not just labelled.
Every Sova Glutathione vial ships with a batch-linked Certificate of Analysis. Before you buy, confirm the CoA references the batch on the vial, that identity is confirmed by ESI mass spectrometry against the expected 307.32 Da, and that purity is measured by reverse-phase HPLC. Enter the batch at /verify to pull the certificate.
Why buy Glutathione from Sova
- ✓HPLC (purity) + ESI mass spectrometry (identity) on every batch — no exceptions.
- ✓A batch-linked Certificate of Analysis you can verify from the code on the vial.
- ✓A higher-capacity 1500mg research vial suited to repeated assay work.
- ✓UK stock, same-day dispatch; supplied strictly for laboratory research use only.

Glutathione — frequently asked
Is Glutathione legal to buy in the UK?
Glutathione is supplied in the UK as a research reagent for laboratory research use only. It is not sold as a medicine, supplement or for human or veterinary use, and can be purchased by researchers aged 18 or over on that basis.
How is Sova's Glutathione verified?
Each batch is analysed by reverse-phase HPLC for purity and by ESI mass spectrometry to confirm the molecular weight against the expected 307.32 Da. A batch-linked Certificate of Analysis accompanies every vial and can be checked at /verify.
What is Glutathione studied for?
Glutathione is the principal intracellular antioxidant and a key substrate in redox and detoxification biochemistry. In research it is used as a reference compound in redox, antioxidant and cellular-energy studies in laboratory systems.
How should Glutathione be stored?
Store the sealed vial cool, dry and away from light. Because reduced glutathione oxidises on exposure to air, keep the vial sealed and prepare working solutions fresh for research use.
