Because of this hypothesis, the effect of vitamin E on NF-κB activation has been examined in many studies, using both in vivo and in vitro models. Most of these studies have observed that vitamin E inhibits the activation of NF-κB, with the greatest inhibition seen with the succinate form. Vitamin E may be inhibiting NF-κB by reducing oxidative stress or through one of its nonantioxidant functions; this is not clear at the present time. It also is not known if the inhibition of NF-κB is necessary for any of vitamin E's effects on gene expression and the resulting physiological effects.
