title: Brief communication: The prevalence of high intake of vitamin E from the use of supplements among U.S. adults.
abstract: BACKGROUND
  People who consume at least 400 IU of vitamin E per day from supplements may be at slightly increased risk for premature mortality.
  
  
  OBJECTIVE
  To estimate the percentage of U.S. adults age 20 years or older who consume at least 400 IU of vitamin E per day through the use of vitamins, minerals, or other dietary supplements.
  
  
  METHODS
  Cross-sectional analysis.
  
  
  METHODS
  The 1999-2000 National Health and Nutrition Examination Survey.
  
  
  METHODS
  Representative sample of the civilian, noninstitutionalized U.S. population.
  
  
  METHODS
  Participants answered questions about the use of vitamins, minerals, or other dietary supplements.
  
  
  RESULTS
  Among 4609 adults, 11.3% (95% CI, 9.7% to 13.1%) consumed at least 400 IU of vitamin E per day from supplements. Such intake increased with age, was about equal for men and women, and was more common among white persons (14.1%; CI, 11.9% to 16.7%) than African-American (3.7% [CI, 2.6% to 5.2%]) or Mexican-American persons (3.9% [CI, 2.8% to 5.4%]). The median dietary intake of vitamin E was 8.8 IU per day.
  
  
  CONCLUSIONS
  Information about vitamin E intake was self-reported.
  
  
  CONCLUSIONS
  The use of vitamin E supplements in dosages of at least 400 IU per day is common among U.S. adults.
