What Glutathione is
Glutathione is the body's principal intracellular antioxidant tripeptide, and its biochemistry is textbook material rather than emerging research. What remains genuinely contested is whether exogenous administration meaningfully raises intracellular levels.
It oxidises readily, and the ratio of reduced to oxidised glutathione in a vial is the number that actually matters. Most research-market certificates never report it.
What the evidence base looks like
The published record here is deep enough that the pharmacology itself is not in dispute; the open questions are about supply quality rather than mechanism.
Our library records roughly 500 relevant publications for Glutathione and grades the evidence as strong. That grade describes the weight of research, not a judgement about safety or effect, and it is reviewed as new work is published.
Supplier quality: what to check on Glutathione
A vial can be pure glutathione and still be largely oxidised, which no standard purity figure will show.
The practical checklist is the same on every product but weighted differently here: a batch-matched certificate of analysis, an identity method appropriate to this molecule rather than purity alone, clear peptide content per 1500mg vial, and a supplier that will answer a technical question before taking payment.
Typical UK pricing
The lowest price we currently track for a 1500mg vial is £44.90, against a market median nearer £64. Compare on price per milligram rather than per vial, because vial sizes across suppliers are rarely identical.
A listing well below the tracked low is worth investigating rather than celebrating. On this compound the cost of doing it properly is largely analytical, and that is the first thing an unusually cheap supplier stops paying for.
