What happens if I take glutathione every day?

This product shouldn’t be taken at all, since it’s sold for laboratory research only. The closest published data come from supplement trials. Richie et al. (2015) gave healthy adults oral glutathione daily for six months and reported higher glutathione in blood and other body stores than with placebo, with levels returning toward baseline after a washout. That trial tested a commercial supplement in capsules.

Oral supplement results don’t apply to research powder, and long-term effects of high intake aren’t well described. In the lab, daily handling raises a different issue: glutathione oxidizes in solution, so a stock made yesterday may hold more GSSG than you expect.
