Calcium Supplements Linked to Lower Mortality Risk
By admin
A few months ago, Women’s Health reported that excessive calcium consumption was linked to a higher risk of mortality. New research now provides more insight on the subject: In a study recently accepted for publication in The Endocrine Society’s Journal of Clinical Endocrinology & Metabolism, researchers report that taking calcium supplements—up to 1,000 mg a day—is linked with lower mortality risk.
A research team from McGill University in Canada analyzed health data from more than 9,000 people that participated in the Canadian Multicentre Osteoporosis Study—though not all of the participants actually had osteoporosis. To get the skinny on calcium supplement consumption, researchers interviewed participants in person every five years and also asked them to fill out a yearly questionnaire about which medications and supplements they were taking.
The women who reported using calcium supplements—up to 1,000 mg per day—had about a 20 percent reduced risk of dying at some point during the 10-year study. Higher doses, however, led to inconclusive results.
That’s in line with research published a few months ago that found women with a calcium intake exceeding 1,400 mg per day increased their mortality risk by 100 percent, compared to those who kept their intake between 600 and 999 mg.
All of this evidence points to the fact that the RDA for calcium—1,000 mg per day for women between the ages of 19 and 50—is in fact the best amount to aim for, says David Goltzman, MD, of McGill University.
The latest research suggests that taking calcium supplements can be a safe way to up your intake—so long as you don’t exceed 1,000 mg per day from both supplements and dietary calcium.
That said, it’s always best not to rely on supplements to meet your nutritional needs. In fact, researchers found similar reductions in the risk of mortality when people increased their dietary calcium intake, as well.
“The most appropriate way to meet your calcium needs is through your diet,” says Goltzman. “If, however, you cannot meet your average daily requirement of calcium, there would be no harm—with respect to increased death—to consume calcium supplements up to 1,000 mg per day.”
