Calcium and Vitamin D Supplements Fall Short in Preventing Fractures, Large Review Finds
A comprehensive review of 69 trials with more than 154,000 adults finds calcium or vitamin D supplements, alone, do little to prevent fractures or falls; even combined use yields tiny, likely clinically insignificant benefits (about 1 fewer fracture per 100 people and ~3 fewer hip fractures per 1,000). The benefits may exist in highly deficient or osteoporotic individuals, but for the general population regular exercise, weight-bearing and balance training, and fall-risk reduction remain the best strategy for bone health.
