A major review published in the BMJ has challenged long-standing clinical advice on bone health, concluding that combined vitamin D and calcium supplements may not reliably protect against fractures in most people.
The analysis found that the supplements, widely recommended for decades to strengthen bones and prevent breaks, do not consistently reduce fracture risk across general populations. The conclusion runs counter to guidance that has shaped public health messaging and individual habits for years.
Vitamin D and calcium are essential for bone formation and maintenance, and supplements have been promoted especially for older adults at risk of osteoporosis. The review suggests that, outside of specific deficient groups, routine supplementation may offer limited benefit.
Fractures, particularly of the hip and spine, are a major source of disability and health costs among aging populations. Preventing them has been a central goal of bone health strategies.
The findings are likely to prompt discussion among clinicians about who genuinely benefits from supplementation. The authors indicate that targeted use in people with documented deficiencies may still be warranted, while broad, population-wide recommendations may need to be reconsidered.
