According to a new study, vitamin D supplements may not reduce heart risks in older women as previously suggested. At total of 305 healthy postmenopausal women aged 60-70 yr were recruited and received a daily capsule of 400 or 1000 IU vitamin D3 or placebo.  Investigators found that the supplements did not have much of an impact on cholesterol, blood pressure and blood sugar.
