Vitamin E status and immune function

Methods Enzymol. 1997;282:247-63. doi: 10.1016/s0076-6879(97)82112-x.

Abstract

Evidence from animal and human studies indicates that vitamin E plays an important role in the maintenance of the immune system. Even a marginal vitamin E deficiency impairs the immune response, while supplementation with higher than recommended dietary levels of vitamin E enhances humoral and cell-mediated immunity. The current RDA level of vitamin E prevents clinical deficiency syndrome but in some situations, especially in older subjects or in a disease state, fails to maintain optimal host defense. The immunological parameters reviewed are all sensitive to changes in the availability of vitamin E and, therefore, may reflect the vitamin E status of a given individual more accurately than conventional methods.
