The purpose of this study was to determine riboflavin intakes and status of Korean adults. Three consecutive 24‐hour recalls and urine samples were collected from 149 healthy adults (70 males and 79 females), aged 20‐65y, living in Seoul and metropolitan area, Republic of Korea. The mean riboflavin intakes (mean/SD) were 1.33/0.34 mg/day and 0.69/0.16 mg/1000 kcal. The subjects aged 20‐29y had the lowest riboflavin intake, significantly lower than the intakes of 30‐39 y olds (P=<0.05). Approximately 25 % of the subjects consumed riboflavin less than the Korean Estimated Average Requirement and 50 % consumed less than the Korean Recommended Nutrient intake for riboflavin. Average urine riboflavin concentration was 205/190 ug/g creatinine. There was no significant difference in urine riboflavin levels among age groups. Eleven percent of the subjects were riboflavin deficient (urine riboflavin <27 μg/g creatinine), and urine riboflavin concentrations of 20.8 % were 27‐<80 μg/g creatinine, which is representative of low riboflavin status. Therefore, one‐third of these Korean adults were at risk of inadequate riboflavin status. Korean adults may need to be encouraged to consume riboflavin‐rich foods.
