globeandmail.com: Vitamin D: Will it fight disease where others have failed?:

"In the four-year study of 1,179 postmenopausal women published in the American Journal of Clinical Nutrition, researchers found that those taking 1,110 IU of vitamin D a day were 60 per cent less likely to get cancer than their peers taking placebos. The women took vitamin D along with calcium.

Earlier studies suggested that the vitamin protects from breast, colorectal, lung and prostate cancers as well as diabetes, multiple sclerosis and rheumatoid arthritis. But the recent study is the first randomized, controlled trial - the most reliable form of clinical evidence - to substantiate that vitamin D is an important tool in fighting cancer."

Maybe, but before we jump in too deep, remember that vitamins in general have had very limited success. So???
