The Calcium Question
Several recent studies raise questions about the recommendations for calcium supplementation to increase bone mineral density and reduce the risk of fractures. These studies showed that increased calcium intake from either supplements or dietary sources may not be as effective in supporting bone mineral density or reducing fracture risk as once thought. Researchers in one study found increased calcium intake resulted in only small increases in bone mineral density in 14,000 people over 50, but the changes were so small they would not be clinically significant (1). Another study revealed increased calcium intake in over 45,000 individuals did not reduce the risk of fractures (2).
Eating a wholesome, natural diet combined with physical activity may be the best way to support bone health and prevent fractures.
