Meta- analysis of BMI values at end of trial showed no statistically significant difference in BMI change by use of 25[OH]D supplementation .
Based on existing published trials , oral 25[OH]D supplementation does not significantly impact BMI change
The impact of 25-hydroxyvitamin D ( 25[OH]D ) supplementation on weight change remains controversial .
The objective of this study was to summarize the effects of 25[OH]D supplementation ( cholecalciferol or ergocalciferol ) on BMI change through a meta- analysis of published clinical trials .
Body Size and Serum 25 Hydroxy Vitamin D Response to Oral Supplements in Healthy Older Adults
Background : Vitamin D insufficiency is prevalent in the northeast United States . Since vitamin D insufficiency is readily amenable to supplementation , it is important to underst and what factors are associated with serum 25 hydroxy vitamin D ( 25(OH)D ) response to vitamin D supplementation . Objective : In this study we examined the association of serum 25(OH)D response to vitamin D supplementation with body size in a population of elderly subjects . Methods : 257 healthy , ambulatory men and women 65 years of age or older were r and omly assigned to treatment with either 700 IU/day ( 17.5 μg/d ) of supplemental vitamin D3 and 500 mg/day ( 12.5 mmol/d ) of supplemental calcium , or to placebo . Results : In multivariate regression analyses , after adjusting for baseline 25(OH)D , season , and sex , we found change in 25(OH)D to be inversely associated with baseline BMI ( p = 0.01 ) in subjects treated with supplements for one year . Change in 25(OH)D was also negatively associated with other baseline anthropometric measurements in these subjects . Conclusion : Our study implies that body size should be taken into account when estimating the amount of vitamin D intake needed to raise 25(OH)D to the desired level
