Vitamin D, Calcium Aid in Weight Loss
STE-FOY, Quebec—Researchers from Laval University observed the effects of vitamin D and calcium supplementation on weight loss in 63 women randomly assigned 600 mg elemental calcium and200 IU vitamin D tablets or placebo daily. All subjects then participated in a 15-week weight loss intervention program. At the conclusion of the intervention, significantlygreater decreases in total, low-density lipoprotein (LDL) cholesterol and the LDL-to-high-density lipoprotein (HDL) cholesterol ratio were observed inthe calcium/vitamin D group compared to the placebo group. These metabolic variables were independent of changes in fat mass and in waist circumference. Researchers concluded vitamin D and calcium benefit the lipid and lipoprotein profile in dieting overweight or obese women with usual low daily calcium intake.
The study was published in the American Journal of Clinical Nutrition (85, 1, 54-59 2007).
