The purposes of this study were to determine folate intakes and plasma folate concentration and to evaluate folate status of Korean adults. Two hundred fifty‐four healthy adults (68 men and 186 women), aged 20–64 years, were recruited in the Seoul and metropolitan area, Gumi, and Kwangju, South Korea, from 2009 to 2011. Three consecutive 24‐hour recalls, information on folate supplementation, and fasting blood samples were collected from the subjects. The dietary and total (dietary plus supplemental) folate intake was 522.79 μg DEF/day and 582.37 μg DEF/day respectively. Folate intake of men was significantly higher than the intake of women (p<0.01). Approximately 16% of the subjects consumed total folate less than the Estimated Average Requirement. Plasma folate concentration was 26.97 nmol/L. Plasma folate of women was significantly higher than that of men. Total folate intake was significantly positively correlated to plasma folate concentration (r=0.32866, p<0.0001). Only 6 % of the Korean adults had plasma folate less than 6.8 nmol/L indicating a folate deficiency. In conclusion, folate intakes of Korean adults were generally adequate with Korean Dietary Reference Intakes for folate. Folate status was also adequate based on plasma folate concentration.
