Daisy I wonder why vitamin K isn't recommended also. I have read about studies and its use in Japan too; when I asked my endo if I should take Vitamin K along with the 50,000 units of Vitamin D2 and the 1200 Calcium Citrate he has me on the answer was "no proven benefit" (his words). So I decided to take it anyway as I don't think I can get enough from food, and it sure sounds like there is a benefit. All I could find was MK4 however. Would be interesting to find how many of us are taking vitamin k, recommended by med pros or not. I wonder if a nutritionist would be of help. Sure seems like it!
