Figure 2.
Effect of increasing vitamin K1 supplement doses on plasma concentrations of undercarboxylated prothrombin and undercarboxylated osteocalcin in study phase I. The values represent the mean plus or minus the standard error of the mean (SEM) change after 7 days' supplementation with each vitamin K1 dose. ucFII indicates undercarboxylated prothrombin (•); ucOC indicates undercarboxylated osteocalcin (▪). The arrows represent the vitamin K1 doses that resulted in significant decreases from baseline for ucFII (100 μg) and ucOC (300 μg), respectively.
