Vitamin D shows promise but research still lagging

[Chicago Tribune, March 10, 2010] As far as Dr. Joseph Mercola is concerned, vitamin D is the magic bullet we've all been looking for. A lack of this wonder nutrient, the controversial natural health advocate said, can set the stage for no fewer than 33 disorders, including autism, cancer, diabetes and infertility.

"Vitamin D appears to reduce your risk of dying from virtually ANY disease," he wrote on his popular Web site. His recommendation? Get more sun, relax in a tanning bed or try supplements such as "Sunshine Mist," a vitamin D spray he sells.

Dr. Greg Plotnikoff of Allina's Center for Innovation says while these claims might be true, they need more supporting evidence.
