Glutathione certificates: what to check
Glutathione is the tripeptide gamma-Glu-Cys-Gly, and its thiol group oxidises readily to the disulfide form, GSSG. The key question on a certificate is therefore whether the reduced form is what was measured. This report gives 99.119% purity and 1597.31mg against a 1500mg label claim. Because the quantity is at gram scale, a modest percentage difference in content is a large absolute amount, which is why we quote the measured figure. Supplied for in-vitro laboratory research only, not for human or veterinary use.
Published research on glutathione GSH GSSG redox assay is indexed on PubMed.
