Glutathione
The body's own antioxidant.
What it is
A tripeptide your cells make themselves, central to how the body handles oxidative stress. Also sold widely as a supplement.
What research has looked at
Studied for antioxidant status, liver function, and, in a few small trials, skin tone.
What's still unknown
Skin-related findings come from small, short studies. How much supplemental glutathione changes levels inside cells is still debated.
