Thank you. You give some very good advice. I certainly will talk with my doctor about it. BTW, I asked her if I should be taking calcium pills when she told me to take the vitamin D, and she said no for studies are showing calcium pills are giving some people strokes. Hard to know what to do, isn't it? For so many years I heard it was very important for women to take calcium pills daily, and I did for awhile. Then got out of the habit. Now I take a multi-vitamin that has everything in it.
