Summary

Experimental and human data suggests that vitamin D could protect against breast cancer. Overweight/obese individuals are at increased risk of low vitamin D levels. Vitamin D may reduce production of fat tissue, thereby reducing weight gain, which would result in lower levels of adipose-derived hormones and other breast cancer risk factors.The purpose of this study is to test the effect of vitamin D supplementation on the response to a weight loss (diet + exercise) intervention and select breast cancer risk factors in overweight and obese postmenopausal women with low blood vitamin D levels.
