I probably take too many supplements and would like to take fewer but not sure that I would do ok if I took out most of them. I have an appt with the rheumatologist next week for my osteoporosis which I hope I have made a dent in correcting and perhaps then I can cut back on some of the minerals. But if I had my choice I would definately just be taking the vitamin D3 and the mag cit. I know that it is only two and you asked for three, but these are the ones I feel have made the biggest difference in my health.
