The treatment of vitamin D insufficiency can decrease the risk of hip and nonvertebral fractures. [35, 36] A meta-analysis by Boonen et al of postmenopausal women and of men aged 50 years or older reporting a risk of hip fracture found that oral vitamin D supplementation reduced the risk of hip fractures by 18% when vitamin D and calcium were taken together. [37] Most of the trials that demonstrated the antifracture efficacy of vitamin D used approximately 800 IU of vitamin D3. The minimum 25(OH)D level at which antifracture efficacy was observed was 30 ng/ml (74 nmol/L), suggesting a threshold for optimal levels of 25(OH)D for fracture protection.
