Vitamin D Effect on Body Fat and Cholesterol
As we have reported earlier, adequate intake of vitamin D may decrease the risk of cardiovascular disease. A new study may help explain why. A 12-week course of vitamin D given to overweight women lead to a boost in HDL ("good" cholesterol) as well as a decrease in body fat. However, total body weight did not change and there was an increase in LDL ("bad") cholesterol, although it appeared to be less plaque-forming in nature. For details, including the dose given, see the updated information in the Vitamin D Supplement Review. More >>
