Calcium and Vitamin D Supplements May Not Prevent Bone Breaks
Supplements containing calcium and/or vitamin D do not appear to protect older adults from bone fractures, despite guidelines recommending them for seniors with osteoporosis, or thinning bones, according to research published in JAMA.
This meta-analysis of 33 clinical trials involved 51,145 adults over age 50 living in their homes and communities, rather than in nursing homes or residential care facilities. The clinical trials were designed to track supplement use – calcium, vitamin D, or both – with placebo or no treatment and new bone breaks.
According to the researchers, calcium and vitamin D supplements were not associated with a lower risk for new fractures, regardless of the dose of the supplement, the person’s gender, or their history of fractures. Dietary intake of calcium and baseline vitamin D blood levels also did not reduce fracture risk.
