Calcium supplements: A risk factor for heart attack?

Answer Section

Calcium supplements are usually taken to treat or prevent bone disease, such as osteoporosis. There is some evidence that calcium supplements can increase the risk of heart attack. Some research suggests that the risk is significantly higher in people with diabetes.

One review of studies found that calcium supplements increased the risk of heart disease, particularly in healthy postmenopausal women. But other studies have said calcium supplements don't increase the risk.

More research is needed to know how calcium supplements affect a person's overall risk of heart attack. What is known is that calcium from food sources isn't a concern. Food sources of calcium include dairy products and leafy green vegetables.

Taking calcium with vitamin D does provide a benefit for people who have bone loss or too little calcium. Ask your healthcare professional if a calcium supplement is right for you.
