Popular Bone Supplements May Not Prevent Fractures, Major Review Finds
Key Points:
- A large analysis of 69 clinical trials involving over 154,000 adults found that calcium or vitamin D supplements alone do not significantly reduce the risk of fractures or falls.
- Combined calcium and vitamin D supplementation showed only very modest reductions in fracture risk, with benefits deemed too small to be clinically meaningful for most older adults.
- Despite widespread use and increased prescribing, especially in countries like the UK, routine supplementation may not effectively prevent fractures in the general adult population without severe deficiencies or bone disease.
- The study emphasizes that maintaining bone health is better supported by regular physical activity, including weight-bearing and balance exercises, alongside a balanced diet and fall prevention strategies.
- Calcium and vitamin D remain essential nutrients, but supplements should be targeted to individuals with specific medical needs rather than used universally for fracture prevention.
