  • A Canadian study suggests calcium and vitamin D supplements may be less effective at preventing fractures and falls in older adults than commonly believed.
  • The comprehensive analysis of 69 trials involving over 150,000 adults found little to no benefit in reducing overall fractures, hip fractures, or falls.
  • Researchers recommend re-evaluating general recommendations for supplementation and focusing on proven fall prevention strategies like balance and resistance training.

New research indicates that the widely accepted benefits of calcium and vitamin D supplements for preventing fractures and falls may be overstated. A comprehensive review of 69 randomized controlled trials, involving more than 150,000 adults, suggests that these supplements offer minimal protection against bone breaks and stumbles.

Calcium and vitamin D supplements may be less effective in preventing fractures and falls than commonly believed.

— Article textSummarizing the core finding of the Canadian research review.

The study, published in the "British Medical Journal," analyzed data from trials comparing calcium, vitamin D, or a combination of both against a placebo or no treatment. The findings, supported by medium to high certainty evidence, revealed that supplementation had almost no effect on reducing the overall risk of fractures. This lack of significant benefit extended to specific types of fractures, such as hip fractures, and also to the prevention of falls.

The evidence certainty is medium for calcium supplementation, high for vitamin D supplementation, and high for combined supplementation.

— Article textDetailing the certainty of evidence for different supplementation types.

While the researchers acknowledge that some included studies had limitations in quality or participant numbers, they maintain confidence in the overall results due to consistency across various subgroups. These subgroups included differences in age, sex, history of fractures or falls, and dietary calcium intake. The evidence suggests that for the general population, the impact of these supplements is negligible.

The research team stated that the current evidence does not support routine supplementation with calcium or vitamin D, or combined supplementation, for fracture and fall prevention.

— Article textPresenting the study's main conclusion regarding supplementation recommendations.

Based on these findings, the research team recommends that clinicians, guideline committees, and regulatory bodies reconsider the current general advice on supplementing with calcium and vitamin D. They suggest shifting focus and resources towards strategies that have a proven track record in reducing falls and related injuries, such as balance training, resistance exercises, and other comprehensive approaches. Further large-scale, high-quality studies are still needed to determine if these supplements could benefit specific high-risk populations.

Clinicians, guideline development groups, and regulatory agencies should re-evaluate general recommendations regarding routine calcium and vitamin D supplementation in light of the current evidence.
