What form of vitamin D should I take?
-
Dr. Rovenia Brock answered:Vitamin D supplements are available in two forms: vitamin D2 and vitamin D3. The D3 form is more active than the D2 form and a better choice when choosing a supplement. Dosage levels range from 400 to 5,000 I.U. Talk to your doctor or health care provider about a simple blood test to determine the right dosage for your individual vitamin D needs.
