Abstract

Polymorphisms in genes involved in vitamin E uptake, distribution, metabolism, and molecular action may be important determinants for the protective effects of vitamin E supplementation. The haptoglobin 2-2 polymorphism is associated with increased production of oxygen free radicals and reduces levels of vitamin E and C; the consequent elevated risk for cardiovascular disease can be prevented by vitamin E supplementation.
