Historically, health care professionals have valued Vitamin D mainly for its relation to bone health. Recently however, there has been growth in substantial scientific evidence that supports the role of Vitamin D in the prevention of cancer.

Birmingham oncologist Luis F. Pineda, MD, MSHA, says studies have shown that adequate serum Vitamin D metabolite levels are associated with substantially lower incidence rates of several types of cancer, including those of the breast, colon, prostate, and ovary. "Scientists now are talking about its correlation with diabetes and metabolic syndrome - a precursor to diabetes - and with immunity in general," he says.
