My doctor said my level is at 22. How much D3 should I take? He prescribed D2.
My doctor prescribed D2 for my lower level of Vitamin D. After browsing your site I realize I should take D3, however, I don't know how much I should take a day. Is there a program that you recommend taking a large amount at first and then tapering off? I'm not sure how much I need to be taking to get my levels back up and then once I get retested what I.U.'s to take to keep them there.
