MBM, just thought I'd update on what I found out. I called the pharmacist to ask if the prescription was for Vitamin D2 or D3 or if it even specified. He said that it was for Vitamin D, but there is no prescription available for Vitamin D3. D3 can only be bought over the counter. The problem is that D3 does not come in as high amounts as the D2 prescription. (My D2 prescription is for 50,000 IU's.) He said that D2 is harder to convert in the body, but that it would; it will just take longer than the D3. He encouraged me to stick with the D2, and call my dr before changing anything.
My dr also wants me taking calcium (1200 mg daily), so I think I'm going to get some Os-Cal Ultra that has 500 IU of D3 in it, and take it along with the D2. I'll only do that a month or two in an effort to raise my D levels, then just take straight calcium.
Thanks again for your help! :001_smile:
