1. What Glutathione is
Glutathione (GSH) is a naturally occurring tripeptide composed of glutamate, cysteine, and glycine (γ-glutamyl-cysteinyl-glycine), synthesized endogenously in nearly all human cells. It is typically supplied here as a lyophilized (freeze-dried) powder for laboratory use, code-labeled by milligram amount.
2. Published literature
This page does not summarize biological findings, outcomes, or mechanisms. Peer-reviewed publications on Glutathione can be located through PubMed. The identity, labeled amount, and analytical results for the DAAVY Research listing are documented in its Certificate of Analysis.
3. Scope of this page
- This page is educational. It documents the identity and analytical testing of a laboratory research material.
- No claims are made about efficacy, safety, or suitability for any use.
- For laboratory research use only. Not for human or veterinary use.
4. What a Glutathione Certificate of Analysis verifies
Because Glutathione is supplied as a lyophilized powder, the analytical questions a COA should answer are: does the vial contain the labeled tripeptide (identity, typically via LC-MS/MS), how much is present relative to the labeled amount (content, via HPLC quantitation), and how pure is the sample (overall purity, via RP-HPLC). See the Interactive COA Decoder for a field-by-field walkthrough and red-flag checklist, and the How to Read a COA guide for the fundamentals.
