why does glutathione injection burn Injections Glutathione Side Effects: What to

The idea is that injecting glutathione gives higher, more immediate systemic levels than oral or topical forms, which theoretically could affect skin pigmentation more strongly

This recycling process relies upon an enzyme called DHFR (dihydrofolate reductase), as well as the MTHFR enzyme

The reduced form GSH is the active form of the molecule, it is the most abundant and it is found inside the cells in millimolar concentrations in the range of 110 mM (highest concentration in liver) (58), while extracellularly they are found in micromolar (GSH in plasma: 1030 M) levels (5, 15, 16)
