Calcium supplements and the heart

Calcium supplements and the heart



Calcium supplements may increase the risk of heart attack. Doctors want more evidence and research before putting this one in the books. This is a tough one if found true. On one hand, Americans simply do not eat enough calcium rich foods hence, the need for calcium supplements. If it indeed increases risk of heart attack, supplements may be discarded. Best is to take more calcium rich foods.
