To determine dietary intakes and plasma concentrations of tocopherols and to evaluate vitamin E status of Korean adults, three consecutive 24‐h food recalls and fasting blood samples were collected from healthy 20–59 y old adults (33 males and 73 females) living in Seoul and Gyeonggi areas, South Korea. The daily vitamin E, alpha‐tocopherol, and gamma‐tocopherol intakes (mean/SD) were 3.84/2.84 mg alpha‐tocopherol equivalents, 3.07/2.27 mg, and 5.98/3.74 mg, respectively. Only 3.7% of the subjects consumed vitamin E > the Korean Adequate Intakes for vitamin E. The plasma alpha‐tocopherol concentration was 15.14/6.84 umol/L. There were no significant differences in tocopherol intakes and plasma tocopherol concentrations among the age groups (P>=0.05). Twenty‐three percent of the subjects had plasma alpha‐tocopherol concentrations <12 umol/L, which is indicative of vitamin E inadequacy status. Approximately 8% and 9% had plasma alpha‐tocopherol to total cholesterol + triglyceride <1.59 umol/mmol and alpha‐tocopherol to total cholesterol <2.22 umol/mmol, respectively, which are also indicative of vitamin E deficiency. In conclusion, most of these Korean adults had inadequate vitamin E intakes, and one‐quarters were in vitamin E deficient status.
