Glutathione is the master antioxidant tripeptide, sitting at the center of oxidative stress defense, liver detox, and immune function. It directly neutralizes reactive oxygen species and regenerates vitamins C and E. Research interest centers on redox balance and mitochondrial integrity.

Storage & handling

Freeze-dried at -4F long term; in solution keep it cold (36-46F), dark, and fresh, never room temperature and never frozen, and discard the moment it yellows (that is oxidation).

Research cautions

FDA has flagged compounded IV glutathione marketed for skin lightening as an unproven use with serious adverse-event reports, and the source guide bars pairing it with chemotherapy outside oncologist supervision.
