Glutathione liquid spray

What is it for?

L-glutathione, the tripeptide of glutamate, cysteine and glycine, in solution at 50 mg/mL — 500 mg across a 10 mL atomiser, a nominal 5 milligrams per actuation. Glutathione oxidises readily once in solution, so this is packaged to limit headspace and wants cold, dark storage from the day it arrives. Refrigerate and protect from light.

• Why glutathione oxidises in solution, and what that does to a certificateGlutathione is defined by a thiol group that wants to give up an electron. Once in solution it pairs off into the disulphide GSSG, and the ratio between the two is the single most useful number about the material.
