Common questions
About this material
Answers describe what the published research examines and where the evidence is limited. They are not claims of any effect; this material is supplied for laboratory research use only.
What is glutathione?
Glutathione (GSH) is a tripeptide built from glutamate, cysteine, and glycine, and it is the cell's most abundant natural antioxidant. It is supplied here as an analytical-grade reference material for laboratory research use only.
Is glutathione a peptide?
Technically yes -- it is a tripeptide, three amino acids linked together. But it acts as an antioxidant and detox molecule rather than a signaling peptide, and its glutamate is joined through an unusual gamma bond that ordinary protein-cutting enzymes cannot easily break.
How is glutathione related to NAC?
N-acetylcysteine (NAC) delivers cysteine, the scarcest of glutathione's three building blocks. Because cysteine supply limits how much glutathione a cell can make, NAC is frequently studied as a way to raise glutathione levels.
Is supplemental glutathione well supported in humans?
The core biochemistry is well established, but applied questions are not settled. How well glutathione taken as a supplement is absorbed, and whether it helps specific conditions, remain active research topics rather than proven outcomes.
How is VNG Labs' glutathione supplied and tested?
Glutathione is provided as an analytical-grade, lyophilized reference material for laboratory research use only, with third-party testing (Vanguard) for identity and purity. It is not a drug or supplement and is not intended for human or veterinary use.
