CALCIUM AND YOUR HEART
ARE YOU PUTTING YOUR HEART AT RISK BY TAKING A CALCIUM SUPPLEMENT? ELIZABETH TRACEY REPORTS
Calcium supplements may increase the risk of heart attack, several worrisome studies have shown recently. Since calcium supplements are recommended for many people, especially postmenopausal women at risk for osteoporosis, the dilemma is obvious. Erin Michos, a cardiologist at Johns Hopkins, offers her opinion.
MICHOS: My take at the moment is food sources may be your best sources to get calcium. Food sources have not been shown to be associated with increased cardiovascular risk and it may be because when you take a calcium supplement it increases your blood calcium levels more acutely within the first six hours after ingestion versus dietary food calcium where it's absorbed more slowly. :24
Michos says there is no known cardiac risk of other medications, such as bisphosphonates used to keep osteoporosis at bay, and that weight bearing exercise is also beneficial. At Johns Hopkins, I'm Elizabeth Tracey.
