The present study showed the correlation between undercarboxylated osteocalcin and vitamin D had a role in production of the undercarboxylated osteocalcin, when the amount of vitamin D 25 (OH) D, (below 30 ng/ml) was decreased, the linear correlation (r) between the vitamin D and undercarboxylated osteocalcin were also decreased r = 0.032 when the level of vitamin D was risen, the linear correlation was 0.274,unfortunately the study-population had little group of the normal level of vitamin D due to most of them were vitamin D insufficiency so the authors could not show the more value of 'r'. However, the present study confirmed that the role of vitamin D information of undercarboxylated osteocalcin (UcOC) which we recognized the UcOC at the low level of vitamin D will misinterpretation of the level of vitamin K2.
