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. We completed a systematic review of English articles, using MEDLINE (Ovid, Pubmed)
from January 1, 1998 through January 1, 2013. The articles selected focused on 25[OH]D supplementation and body mass index
(BMI) in randomized controlled trials (RCT?s). The association between 25[OH]D and mean BMI change was estimated utilizing
a random effects model. A total of 30 studies were reviewed and 9 were included in the meta-analysis. Total participants included
1651 adults (82.6% women and mean age 47.9 years) and 501 were supplemented with 25[OH]D and 518 were controls. Mean
follow-up ranged between 6 to 196 weeks and mean daily 25[OH]D dose ranged from 200 IU to 1,110 IU. Five of the 9 studies
included calcium supplementation in both groups. Average baseline BMI was 30.7 and 30.4 kg/m
in the intervention and control
groups, respectively. Five studies suggested a beneficial effect for 25[OH]D supplementation for BMI change whereas 3 studies
showed no effect of 25[OH]D supplementation on BMI change, and one showed a non-perceptible change. 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.
