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 .
Influence of Calcium and Vitamin D Supplementation on Weight and Fat Loss in Obese Women
Background : Dairy products not only reduce the risk of hypertension and cardiovascular diseases but may play a role in the treatment of obesity . As there is some evidence that calcium ( Ca ) and vitamin D may play a role in effective weight management , we decided to evaluate the influence of Ca and vitamin D supplementation on weight and fat loss  in obese women . Material and Methods : Forty obese women were enrolled in this study . Subjects were divided into 2 groups comparable with body mass index ( BMI ) and age . Group 1 was provided with calcium carbonate and 1-(OH)-vitamin D supplementation . Group 2 was provided with only a diet . Subjects participated in a 3-month weight reduction therapy ( balanced diet , modification of life style , and regular physical exercise ) . Blood sample s ( serum concentration of Ca , phosphorus ( P ) , parathormone ( PTH ) , 25-(OH)-D3 ) and clinical characteristics ( weight , height , BMI , body composition ) were taken at baseline and after the 3-month program . Results : No significant differences of body weight , body fat content , serum parathormone , 25-(OH)-D3 concentration , and plasma total Ca and P concentration were observed between analyzed groups both before and after the treatment . Additionally , we did not observe any significant influence of Ca and vitamin D supplementation on weight and fat loss . Conclusion : Ca plus vitamin D supplementation during a 3-month low caloric diet has no additional effect on weight and fat loss in obese women
