Calcium and vitamin D supplements show limited fracture prevention benefits

The researchers acknowledge that some analyses included a small number of trials and participants, so these findings should be interpreted with caution, and results may not apply to individuals with specific bone disorders or to those receiving drug treatment for osteoporosis.

However, the findings were consistent after further analyses to account for differences such as participant age, sex, history of fractures and falls, and average dietary calcium intake, supporting the strength of their conclusions.

As such, they say these findings "do not support routine supplementation with calcium or vitamin D, or combined supplementation to prevent fractures and falls" and they suggest clinicians, guideline panels, and regulatory agencies "should re-evaluate their general recommendations for calcium and vitamin D supplementation in light of current evidence."

Evidence from rigorous and well powered trials is needed to inform recommendations for supplementation in higher risk groups, say researchers in a linked editorial.

In the meantime, they suggest that focus and funding should be redirected towards interventions that have been shown to offer meaningful prevention of falls and falls related injuries, such as balance and resistance exercise, and interventions that combine elements like exercise, hazard assessment or education, tailored to individual risk.
