Calcium supplements increase lifespan in women
Calcium, normally associated with dairy products, is an essential nutrient for bone health, and recent research suggests it could also help women live longer lives. Although past studies have linked calcium supplements to heart disease risk, a recent study from McGill University in Montreal found that a moderate level of calcium supplementation—up to 1,000 mg per day—can lower the mortality risk for women.
This study used data from the large-scale Canadian Multicentre Osteoporosis Study, which monitored the health of 9,033 women between 1995 and 2007. Benefits were seen in women who took daily calcium supplements, and it did not matter if the supplement also contained vitamin D, which has also been associated with longevity. While women were found to have lower death risk with supplementation, no similar benefit was seen in men.
Though the study referenced calcium supplements specifically, the researchers noted that the source of calcium was irrelevant, whether it came from dairy, non-dairy or supplements.
