Calcium Supplements Linked to Boost in Heart Attack Risk

Although millions of people take calcium supplements to boost bone health and ward off osteoporosis, New Zealand researchers say the supplements have little effect on bone strength and contribute to a small increase in the risk for heart attack among older people.
Rather than relying on calcium supplements, the researchers suggest that people get their required calcium, if possible, from foods.
“When you look at major trials where people have been randomly assigned to take calcium or placebo, there is an increase in the risk of heart attack in the people who were randomly assigned to take calcium,” said the study’s lead researcher, Dr. Ian Reid, from the Department of Medicine in the Faculty of Medical and Health Sciences at the University of Auckland.
