                                In healthy cells, over 90% of the total glutathione pool exists in its active, or reduced, form. This essential molecule, known as glutathione, naturally occurs in two distinct types—reduced (GSH) and oxidized (GSSG)—and plays a pivotal role in protecting the body from oxidative damage.
