Research background

Glutathione is a tripeptide of glutamate, cysteine and glycine with a structural quirk: the glutamate bond is gamma rather than alpha, which makes it resistant to ordinary peptidases. It is the most abundant non-protein antioxidant in the cell.

What is studied about it is redox balance: the ratio between its reduced form (GSH) and its oxidized form (GSSG) is used as an indicator of a cell's oxidative stress. It also takes part in phase II conjugation through the glutathione S-transferases and is the cofactor of the glutathione peroxidases. A recurring point in the literature is its poor oral bioavailability, which is what has pushed research towards other routes and towards its precursors.

Reconstitution and handling

Work on a clean surface and disinfect the vial stopper with an alcohol wipe before piercing it.
Add the bacteriostatic water slowly, letting it run down the inner wall of the vial rather than landing on the powder.
Do not shake. Swirl the vial gently until the lyophilized powder has fully dissolved: vigorous agitation degrades the peptide.
The solution should come out clear. If it turns cloudy or shows suspended particles, do not use it.
