JeanneMarie,
I am not a doctor so take what I share with a grain of salt. There have been a number of reports in the last year+ about recent studies on the benefits of calcium supplements. These studies have been showing an increased risk of heart attack in those who take calcium supplements. You might want to ask your doctor about this. My naturopath suggested I not take calcium supplements and to find calcium through other more natural sources. It's even been in the news, on the radio etc... I just wanted to share this - again - I am no expert.
