A Message from Dr. Joseph Mercola
I've been advocating the benefits of Vitamin D for years. Vitamin D Deficiency is a very real, global epidemic and I am passionate about helping people address and prevent the diseases associated with it. If you want to know more about Vitamin D, visit my website, Mercola.com. It is the world's #1 Natural Health Website and is packed with thousands of health articles that I've written based on my research as a doctor of osteopathy. I am a licensed physician and surgeon in the state of Illinois and have treated over 20,000 patients. Two of my books are New York Times Bestsellers and I have been featured on the Today Show, CNN, ABC's World News Tonight with Peter Jennings, CBS, NBC and ABC local news shows.
