Responses (5) Hi Rutvij, vitamin D deficiency sure can cause pain and havoc with our bodies. I also had the same problem, but my doctor had me take a prescription vitamin D, once a week, at 50,000 IU's. If you take too much it can be toxic and cause problems as well as a deficiency.
A: There are two different forms of vitamin D, D2 or ergocalciferol and D3 or cholecalciferol. The prescription strength vitamin D is ergocalciferol (D2, Drisdol) and comes in a dose of 50,000 international units (IU), which is usually taken once a week.: The vitamin D that is prescription and is 50,000 IU is vitamin D2 (ergocalciferol). The over-the-counter vitamin D is vitamin D3 (cholecalciferol). Each is absorbed differently by the body and therefore they have different bioequivalence.
