"Calcium supplements may risk heart attack"
According to a study older people and especailly women who regularly take calcium supplements to strengthen bones and prevent fractures are at increasing their risk of having a heart attack.
Researchers from the University of Zurich and German Cancer Research Centre in Heidelberg claimed their study shows a good evidence that the supplements are "not safe or particularly effective" .
In their study, the researchers followed 23,980 people for 11 years and found that those taking calcium pills roughly doubled the risk of having a heart attack . There were 851 heart attacks among the 15,959 people who did not take any supplements at all. However, people taking calcium supplements were 86% more likely to have had a heart attack during the study.
