Calcium supplements that many women take to boost bone health increase their risk for heart disease, a new study by researchers at Johns Hopkins Medicine and other institutions has found.
The results show calcium supplements make people more prone to plaque buildup in arteries, which contributes to the risk of a heart attack.
The study, published Tuesday in the Journal of the American Heart Association, is the latest salvo in a nearly decade-long debate about whether the supplements do more harm than good.
The researchers said their findings give patients reason to use caution when taking the supplements. It is better for people to get calcium from food such as dairy products, leafy green vegetables, and fortified cereal and juices, they said.
