Meta-analysis of the effects of vitamin D supplements on bone mineral density in adults

Reid Ian R , Bolland Mark , Grey Andrew

Recent meta-analyses of vitamin D without co-administration of calcium have not demonstrated fracture prevention, possibly through lack of power, inappropriate choice of doses, or failure to target the intervention to deficient populations. Bone mineral density (BMD) is able to detect biologically significant effects in much smaller cohorts, so is a relevant surrogate measure with which to re-assess the skeletal efficacy of these supplements. We searched Web of Science, Embase...

Acute effects of calcium supplements on blood pressure: results of a randomised cross-over trial

Calcium supplements are associated with increased cardiovascular risk, but the mechanism by which this occurs is presently uncertain. In a secondary analysis of a trial examining the acute effects of calcium supplements, we found that blood pressure declined over 8 h in the control group, consistent with its diurnal rhythm, and that this decline was smaller in the calcium group [1]. To investigate these effects further, we carried out a randomised controlled cross-over trial o...

DMAb increases BMD and reduces bone resorption and risk of vertebral, nonvertebral and hip fractures in women with PMO. Transiliac crest bone biopsies in 47 subjects treated with DMAb for 1–3 years showed reduced bone turnover vs 45 Pbo-treated subjects, which reversed on treatment cessation. Since bone turnover reduction is sustained and fracture incidence low over 6 years’ DMAb treatment, we evaluated DMAb’s effects on tissue-level remodelling in the FREEDOM E...
