Taking vitamin D? Read the label.

Created date

In supplements and fortified foods, vitamin D is available in two forms ergocalciferol (D2) and cholecalciferol (D3). Some studies indicate that cholecalciferol could be more than three times as effective as ergocalciferol in raising your blood levels if you are deficient. Many supplements are therefore being reformulated to contain cholecalciferol. But check the label to be sure.
