Research review: Enhanced blood glutathione levels by oral supplementation
A recent human clinical trial showed that oral supplementation of Setria® glutathione (GSH) increased levels of GSH in the blood. The study found that the increase was in most cases dose and time dependent, and that levels returned to baseline after a one-month washout.
The researchers also examined immune function markers and found that cytotoxicity was enhanced more than two-fold for participants taking 1000mg daily for three months. These findings support claims of oral glutathione’s bioavailability as well as its potential to enhance immune function.
