Despite the role vitamin E may have in protecting against various chronic conditions, little is known about vitamin E status in the US population. Using data from the Third National Health and Nutrition Examination Survey (1988-1994), the authors examined the distribution and correlates of serum alpha-tocopherol among 16,295 US adults aged 18 or more years. The mean concentration of alpha-tocopherol was 26.8 mumol/liter (geometric mean, 25.0 mumol/liter). The 25th, 50th, and 75th percentiles were 19.6,24.1, and 30.4 mumol/liter, respectively. The mean alpha-tocopherol/cholesterol ratio was 5.1 (geometric mean, 4.9) ; the 25th, 50th, and 75th percentiles were 4.1,4.7, and 5.5 (10-3), respectively. About 27% of the US population had a low alpha-tocopherol concentration (
