Most multivitamins contain 35 to 40 IU of vitamin E. Thus, vitamin E intake of 400 IU or above can only be achieved with supplementation. The use of high-dose vitamin E supplements in dosages of at least 400 IU daily is common among US adults (Ford et al 2005), with approximately 11% of US adults consuming at least 400 IU of vitamin E supplements daily, and with the frequency of supplement intake increasing with age. The use of vitamin E supplements in dosages of at least 400 IU daily is even more common among health care professionals, with almost two thirds (64%) of male physicians reporting daily vitamin E intake of 400 IU or more (Muntwyler et al 2002).
