A study published recently in the British Medical Journal has found that a vitamin-mineral combination of vitamin D and calcium significantly reduced fractures by 8%, and hip fractures by 16%. The study involved almost 70,000 people across Europe and the US and the reduction in risk was for everyone, regardless of age or gender.
