New Study Debunks Calcium and Vitamin D Supplements for Bone Health

A new study published in the British Medical Journal challenges the long-held belief that calcium and vitamin D supplements help prevent bone fractures and falls. The findings, based on data from nearly 154,000 participants, suggest these supplements may offer little to no benefit for most people. The research analysed 69 trials involving 153,902 individuals, the majority of whom were not at high risk of fractures or falls. Results showed that neither calcium, vitamin D, nor their combination significantly reduced the likelihood of such incidents. Olivier Massé, one of the study’s authors, stated that these findings align with recent evidence questioning the routine use of these supplements.

David Goltzman, a professor at McGill University, highlighted that vitamin D levels naturally vary with the seasons. Many people remain unaware of their own levels, making blanket supplementation unnecessary. He advised that those already sufficient in vitamin D may not need extra intake. The study authors recommended focusing on regular exercise and a diet rich in vitamin D and calcium instead. Massé also suggested consulting healthcare professionals before continuing with supplements, as individual needs may differ. Future research could explore alternative interventions beyond calcium and vitamin D for fracture and fall prevention. Few strategies have consistently proven effective in reducing fracture risks, aside from exercise and osteoporosis drug treatments. This study reinforces the need for personalised approaches rather than widespread supplementation.

The findings cast doubt on the routine use of calcium and vitamin D supplements for bone health. Instead, exercise and dietary adjustments are emphasised as more reliable ways to maintain strong bones. Healthcare guidance remains key for those considering whether to continue supplementation.
