But people who are deficient in vitamin D actually see a greater protective benefit when they supplement, reducing their risk by 50 percent.
A new review of studies on vitamin D supplementation show that it does not have a major effect on common chronic diseases. There is no evidence that the risk for heart disease, cancer or stroke is significantly reduced. In previous studies, relatively small doses of vitamin D were given IU, or less, daily for limited periods of time and to relatively small groups of people. Currently, several high quality studies supplementation with high doses to larger groups of people for longer periods of time, and the first results are expected to come in They will give us much more reliable knowledge.

In fact, even a minuscule increase in a key D precursor caused the study participants to incinerate an additional half pound of flab.
