Answer

Results from another meta-analysis, evaluating the efficacy of oral vitamin D supplementation in the prevention of hip and other nonvertebral bone fractures in individuals aged 65 years or older, indicated that vitamin D offers dose-dependent fracture protection. [38] The analysis, by Bischoff-Ferrari et al, took into account 12 double-blind, randomized, controlled trials (RCTs) for nonvertebral fractures (n = 42,279) and 8 RCTs for hip fractures (n = 40,886), comparing the results obtained from the use of oral vitamin D (with or without calcium) with those derived from the administration of calcium alone and from placebo use.

In this study, doses of more than 400 IU/day were found to reduce fractures by at least 20% in individuals aged 65 years or older. [38] In contrast to the Boonen study, the investigators maintained that these effects were independent of calcium supplementation.
