Vitamin D and Body Weight

The Evidence

A systematic review of the evidence performed in 2009 for the Institute of Medicine by the Tufts Evidence-based Practice Center in preparation for revisions to the Dietary Reference Intakes for vitamin D and calcium concluded the following regarding vitamin D and body weight:1

  • No studies evaluated serum 25(OH)D concentrations and risk of obesity or overweight;
  • Only randomized controlled trials were evaluated for changes in body weight;
  • Three randomized controlled trials compared a range of dosages (300 IU/d to 120,000 IU every 2 weeks) to placebo in terms of changes in body weight;
  • Vitamin D supplementation had no significant effect on body weight change.
