Abstract Vitamin D is important for maintaining bone health and may prevent various diseases i.e., cardiovascular disease and cancer. The aim of this study was to estimate vitamin D intakes of Korean adults using the Korea National Health and Nutrition Examination Survey KNHANES, 2009 data and a newly established vitamin D database. KNHANES 2009 participants n = 4541; 2021 men; 2520 women aged ≥20 years were included. Dietary vitamin D intake, serum 25-hydroxyvitamin D 25OHD, and the relationship between vitamin D intake and serum 25OHD were evaluated. In men and women, vitamin D intakes were 4.00 ± 0.17 µg-day and 2.6 ± 0.1 µg-day respectively, and serum 25OHD concentrations were 19.78 ± 0.33 ng-mL and 17.10 ± 0.26 ng-mL respectively. Serum 25OHD concentrations of men aged <50 years and women aged >20 years were under 20 ng-mL. After adjusting for confounding factors, the positive relationship between vitamin D intake and serum 25OHD was observed in total subjects p < 0.05, excluding participants ≥50 years old. The main food sources for vitamin D among Korean adults were fish-shellfish 71.34% and egg 14.89%. Korean adults should increase their serum 25OHD concentrations by increasing vitamin D intake.
