This study was conducted to provide a vitamin B<sub>12</sub> database for the representative Korean food items and to assess the dietary intake assessment of vitamin B<sub>12</sub> for Koreans. The vitamin B<sub>12</sub> content of 106 foods had been determined by high performance liquid chromatography (HPLC) using column switching method. Rich sources of vitamin B<sub>12</sub> were meats, milk, and egg (0.3-3.4 μg/100 g). Vegetables and fruits contained vitamin B<sub>12</sub> below limit of detection (LOD). The major food sources for vitamin B<sub>12</sub> intake were milk (72.0%), meats (22.3%), egg (3.6%), and fishes & shellfishes (2.1%). Mean vitamin B<sub>12</sub> intake of Koreans was 3.16 μg/person/day. The proportion of population with intake below estimate average requirement (EAR) and above recommended intake (RI) of vitamin B<sub>12</sub> was 60.7 and 36.5%, respectively. The vitamin B12 intake level of young children with 1-2 years which was 834.6% of RI while the intake level of the older adults 50 years and older was only 70.0% of RI. Also, there were regional differences between urban and rural area. The population with intake below RI was larger than that with intake above RI in Korea.
