You can probably pop those calcium supplement pills for bones without worrying much about how they would affect your heart. A new study shows that calcium supplement intake need not necessarily increase the risk of cardiovascular diseases in women.

Researchers examined supplemental calcium use and incidents of cardiovascular disease in a prospective cohort study of 74245 women. The women did not have cardiovascular disease or cancer at the start of the study. Also know about the foods that are rich in calcium.
