Strong Support
A diabetes drug called Exendin-4 helps some pancreatic cells survive when they’re attacked by a harmful chemical called hydrogen peroxide, boosting their survival by up to 38%, but it doesn’t help when other toxins are used—and it doesn’t turn on the cell’s natural defense genes, so it’s probably not working by fighting free radicals.

The study tested exendin-4 and found it only slightly helps beta cells survive oxidative stress, but doesn’t boost the cell’s natural defense genes — just like the claim says. It doesn’t help against other stresses either, so it’s not working as an antioxidant.
