A member asked:
My doctor is prescribing d2 for vitamin d deficiency but i would prefer d3 as i heard it is more effective. my vitamin d level is 12 ng/ ml. ?

You are right: Vitamin D3 is more natural, more effective and stays in the body longer. You do not need a prescription. Take about 5000 units a day for about three months and after than you may reduce your intake to about 2000 units/day. You are deficient in vitamin D and should take D3.
