glutathione gst GST-Tag Isolation from bacteria;optimized to yield ~1mg/50ml culture of soluble GST tagged protein HOOK GST Protein Purification (Yeast) Antioxidant function of glutathione. GST:

Glutathione has a slight edge in speed, NAC has a significant edge in cost (roughly $0.30 per dose vs $23 for liposomal glutathione)

Other mechanistic studies show that oral NAC is poorly absorbed with no renoprotective effects (53)

High sugar & processed foods spike free radicals, burning through glutathione reserves at a faster rate

dysfunctions of intracellular signaling networks, e.g., p53, nuclear factor-B, and Janus kinases

As much as these injections help improve the health of ones skin and promote anti aging benefits, there are safety issues plus cost although provider competence must never be ignored
