Interesting re: calcium. My cardiologist told me that taking the one 600 mg +D a day is fine. I don't take it 3 times a day as recommended on the label. And I have a genetic predisposition to build plaque. My Gyn had been on my case to take Fosamax or some generation of that. I can't due to stomach issues and lower mandible dental implants. Now with the information coming out about femur fractures caused by osteo bone builders, he has backed off. I have osteopina in my lower back and left hip. Due for a bone density scan, hopefully no change. But, I eat kale, power walk 3 miles a day lift weights and do Pilates 2 times a week. Having strong muscles supports the bones and makes them less fragile. And weight bearing exercise slows down bone loss. I have an echo/stress test on Monday, I think I'll ask my cardiologist about the calcium again, see if he's changed his mind. Keeping my fingers crossed that there is less fluid around my heart.
