Glutathione is an abundant intracellular thiol (a compound containing a sulfhydryl group) and low molecular weight tripeptide found in living cells.* Serving as an antioxidant in all types of tissues, the antioxidant functions of glutathione include recycling vitamins C and E to their antioxidant form to minimize oxidative stress.*
Aside from being an antioxidant powerhouse, glutathione is also helpful for detoxification, immune support, and maintaining healthy aging
Consider trying topical GHK-CU only at low concentration before attempting injections again
For diabetic wound healing, which is notoriously slow and prone to complications, GHK-Cu incorporated into collagen dressings produced dramatically better outcomes: higher glutathione and ascorbic acid levels at the wound site, better epithelialization, and significantly more active fibroblasts and mast cells compared to standard dressings
Therefore, the intracellular levels of GSH are regulated by the negative feedback of GSH itself on the GCL enzyme (5557) and by the availability of the amino acid L-cysteine (58)
