I agree with the fact that studies have not shown HCG helps with weight loss in addition to the 500 cal diet. We have many studies in diigo supporting this. However, the FDA is stepping out of its authorized scope.
Vitamin D supplementation finds no increased risk on breast cancer risk. This is a negative study (meta-analysis) on vitamin D and breast cancer in postmenopausal women. The strength of evidence lies with positive effects as numerous studies are documented in diigo here.
