@maryandnans have you gotten a plasma blood test? You should so you know. I was put on calcium MULTIPLE times before a doctor pulled a lab. Why? Because I'm a menopausal woman. Guess what? They had to call me at home to say DON'T TAKE CALCIUM SUPPLIMENTS. Good thing too! Because 15 years later, I found out I have coronary artery disease (inherited). The last thing you want to do is add calcium, which hardens your arterial walls. ASK YOUR DOCTOR FIRST. (I suggest)
