Cholecalciferol or vitamin D3 is the most biologically active and preferred form of vitamin D.
Micellized D3 as cholecalciferol 1200 IU is a natural, soy free, form of Vitamin D in a water-soluble micellized form.
Micellization greatly increases the solubility, absorption and bioavailability of our vitamin D3 over oil or emulsified forms.* The micellization process produces tiny droplets (micelles) that are then formed into highly absorbable aggregate structures.
