If your osteoporosis is pretty advanced, just diet and exercise likely won't do much. I wish I could figure out why the calcium is not going into my bones! I test for plenty of mineral and vitamin d in my labs, but have bad osteoporosis anyway. Why aren't there more studies on what is needed - naturally - to make calcium go into bones, and why it doesn't in the first place? I exercised all my life, always active. I never react well to pharmaceuticals, so now am trying collagen and vitamin K....my naturopath advised MK4, 20-45mcg daily. Have to make sure it's MK4...there are many forms of vitamin K and most bone supplements do not have this form in it. Wish our drs here in US knew more about alternative treatments to drugs.
