Key Points
- Researchers analyzed 69 clinical trials involving nearly 154,000 people.
- Calcium and vitamin D supplements showed little benefit in preventing falls or fractures.
- Experts say balance training and strength exercises may be more effective.
- The findings may not apply to people with osteoporosis or specific bone disorders.
- Health authorities are being urged to review current supplementation guidelines.
Millions of people take calcium and vitamin D supplements believing they help protect bones and prevent falls as they age. However, a major new analysis is raising questions about whether those supplements deliver the benefits many people expect.
Researchers reviewed data from 69 clinical trials involving more than 153,000 adults and found little to no clinically meaningful evidence that calcium supplements, vitamin D supplements, or a combination of both significantly reduce the risk of fractures or falls in most older adults.
The findings have sparked debate among healthcare professionals because calcium and vitamin D have long been recommended as part of routine bone-health strategies for seniors.
What Did the Study Find?
The review examined participants who took calcium, vitamin D, or both, comparing them with people who received a placebo or no treatment.
Researchers found that supplementation provided little or no meaningful reduction in overall fracture risk, hip fractures, or falls.
The results remained consistent across different age groups and populations, even after accounting for factors such as previous fractures, previous falls, sex and dietary calcium intake.
Why Are Falls a Concern?
Falls remain one of the biggest health risks facing older adults.
Health experts estimate that nearly one in three people over the age of 65 experiences a serious fall each year. Such incidents can lead to fractures, loss of independence, long-term disability and increased healthcare costs.
Because of this risk, calcium and vitamin D supplements have become widely prescribed in many countries.
What May Work Better?
Researchers and health experts increasingly point to physical activity as a more effective way to reduce fall risk.
Balance training, resistance exercise and strength-building programs have shown stronger evidence for helping older adults maintain stability and mobility.
Some researchers also note that balance depends not only on muscle strength but on complex interactions between the brain, sensory systems and motor function, all of which can decline with age.
Should People Stop Taking Calcium or Vitamin D?
The researchers cautioned that their findings do not apply to everyone.
People with osteoporosis, certain bone disorders, vitamin deficiencies or those receiving treatment for bone-related conditions may still benefit from supplementation under medical supervision.
Experts say individuals should consult healthcare professionals before making changes to prescribed medications or supplement routines.
For most healthy older adults, however, the study suggests that exercise, balance improvement and fall-prevention programs may deserve greater attention than routine supplementation alone.
