Glutathione (GSH) is an endogenous tripeptide (-L-glutamyl-L-cysteinyl-glycine) and the most abundant intracellular antioxidant in mammalian cells
In catalase-overexpressing cells, these antiproliferative responses were found to be the result of decreased activities in cyclin-dependent kinases (cdk) caused, in part, by the upregulation of Cdk inhibitors p21 and p27 (278)
However, "reversible" is relative
Typically, they contain just the active ingredient, water and sodium chloride (table salt) and are therefore an excellent choice as an alternative to the daily intake of certain B12 tablets, which often contain harmful sweeteners, colourings and flavourings
