Abstract
Summary
Both excess dietary vitamin E and vitamin E deficiency in rats can significantly depress the activity of GSH peroxi-dase in liver and plasma of rats. Of all the six levels of vitamin E tested in this study, the dietary level of vitamin E found to maintain the maximum activity of GSH peroxi-dase in tissues of rats was somewhere between 25 and 250 IU/kg diet. This study conclusively indicates that the excess dietary vitamin E represses GSH peroxidase activity.
