Calcium supplements linked to longer lifespans in women

Taking a calcium supplement of up to 1,000 mg per day can help women live longer, according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).

Calcium, an essential nutrient for bone health, is commonly found in dairy products as well as vitamins. Although calcium is an essential nutrient for bone health, past studies have linked to heart disease risk. Researchers analyzing data from the large-scale Canadian Multicentre Osteoporosis Study (CaMos) sought to clarify this issue and found moderate doses of calcium supplements had a beneficial effect in .

"Our study found daily use of calcium supplements was associated with a lower risk of death among women," said the study's lead author, David Goltzman, MD, of McGill University in Montreal, Canada. "The benefit was seen for women who took doses of up to 1,000 mg per day, regardless of whether the supplement contained vitamin D."

The longitudinal cohort study monitored the health of 9,033 Canadians between 1995 and 2007. During that period, 1,160 participants died. Although the data showed women who took calcium supplements had a lower mortality risk, there was no statistical benefit for men. The study found no conclusive evidence that vitamin D had an impact on mortality.

"Higher amounts of calcium were potentially linked to longer lifespans in women, regardless of the source of the calcium," Goltzman said. "That is, the same benefits were seen when the calcium came from dairy foods, non-dairy foods or supplements."
