Oxidative stress: revaluation of values

It is generally believed that the amount of oxidized glutathione indicates whether the cell is healthy or in a state of oxidative stress. But a group of German scientists proved that this assumption, on which the conclusions of a large number of scientific studies are based, is absolutely untenable.
