GSH From Antioxidant to Post-Translational Modifier (PMC, 2016) S-Glutathionylation as a Major Redox Signalling Mechanism A review published in PMC, authored by a leading researcher in the field, documented GSHs evolution in the scientific literature from a simple antioxidant to a key post-translational modifier through S-glutathionylation the reversible formation of mixed disulfides between GSH and protein cysteine residues

These nutrient precursors include the amino acids cysteine, glycine, and glutamine, as well as selenium, alpha lipoic acid, selenium, vitamin C, milk thistle extract, and aged garlic
A steady level of glutathione is essential for reducing oxidative stress, preserving mitochondrial function, and maintaining immune stability
Elevated intracellular GSH levels represent both a barrier to conventional therapies and an opportunity to design redox-responsive drug delivery systems
