Ercalcidiol 是维生素 D2 的代谢物，可用于监测维生素 D 治疗。

Ercalcidiol is a metabolite of vitamin D2 and can be used in monitoring vitamin D therapy.

The half-life of Ercalcidiol is shorter than that of 25(OH)D3 and Ercalcidiol binds less well to the vitamin D binding protein, making Ercalcidiol less potent and required much higher doses than vitamin D3 [2].
