@jeepgrl : Yes, when my new family doctor found that I was diagnosed with osteoporosis more than 20 years before I became his patient, he did suggest one of the very popular medication specialized in treating low bone density. But I only took a few days and stopped on the ground that I didn't like the side effects came with it. My doctor seemed to be satisfied with my promise that I would continue my calcium and Vitamin D3 + K2 supplements plus regular exercise. I subsequently dropped calcium tablets after reading so many stories about calcium ended up in arteries instead of bones. I'm not as well-read as you are, mkoch. I guess I'm just a person who believes in what was given by nature and would become very uneasy when I cannot justify my taking more varieties of supplements each meal than foods. What puzzled me is: If something seems to be satisfactory in blood test still needs to be supplemented, are we going to supplement everything else in order to be healthy?
