Uploaded to YouTube on 27 Dec 2011 so an old video now but information still very relevant.
http://www.DrKrupka.com Dr. Krupka gives a detailed account of how Multiple Sclerosis (MS) is affected by vitamin D levels and Viral history. This is some serious content and worth watching more than once. If you have an autoimmune disease or know someone who does, grab your pen and paper to take notes and change your life!! Pass it on to your friends. http://youtu.be/yhUuf2QZd_E
