A landmark review published in the British Medical Journal has found that calcium and vitamin D supplements, commonly recommended for older adults to prevent bone fractures and falls, offer little to no benefit. The study, conducted by researchers from CIUSSS du Nord-de-l'Île-de-Montréal, analyzed 69 clinical trials involving over 153,900 adults and concluded that neither calcium nor vitamin D supplements effectively reduce fracture risk, even in individuals diagnosed with osteoporosis. This challenges the long-standing NHS guidance that encourages older adults to take these supplements. The NHS reportedly spends over £111 million annually on vitamin D prescriptions, a figure that has surged from £13 million in 2001. Experts argue that the funds could be better utilized in promoting exercise programs, which have demonstrated significant benefits for bone health. While some nutritionists caution against completely eliminating supplement recommendations, especially for those with severe deficiencies, the study's findings prompt a reevaluation of current public health guidelines regarding calcium and vitamin D supplementation.
