Thanks for all the info; I am hesitant to take that high vitamin D especially now that my numbers are normal...and have been for a year. I would love to take D3; have a note in to my doctor but I have a feeling he won't be happy with me questioning his protocol (I've been questioning since the start of all this, and I get the feeling he picks what he feels is appropriate treatment regardless of my questions or concerns). Since there is no osteoporosis specialty, I am hesitant to change doctors as it would take a while - mine is an endo. I have had consults with gynecologist, orthopedic doc, rheumatologist and they all said take the meds; but some have different ideas of which ones, including which supplements. When I checked into Vitamin K current endo said no proven benefit (?). No explanation, no communication about perhaps trying it, no reason to not take it, etc. My sister's doctor also had her take D3. I may go ahead and do it any doc's blessing or not!
