Calcium Supplements Linked to Heart Attacks
Calcium supplements are a good way to keep bones strong, but there's new concern Thursday they could lead to an increased risk for heart attack.
Lisa Kwock has two problems: her bones are thinning and her cholesterol is high. She's taking calcium, but now she's worried that what may help her bones may hurt her heart.

"I think why this study concerns me is because of all the different factors I represent," said Kwock. "At some point we're going to have to make a decision as I get older."
It's a decision faced by millions, CBS News Medical Correspondent Dr. Jon LaPook reports. New research released Thursday night looked at 11 studies involving 11,921 patients. Those receiving calcium supplements had a 31 percent increase in heart attacks.
"I think it's important for us to look at this study and rethink our practice," said Dr. Suzanne Steinbaum, director of women's health and heart disease, at Lenox Hill Hospital in New York City. "We shouldn't just recommend supplementation to all of our patients."
More study is definitely needed, but now it looks like it's better to get calcium through food, which doesn't seem to cause this type of heart problem.
