Below is a video about vitamin D that will change your life and possibly help you overcome serious diseases and medical conditions. This video is presented through the University of California Television, UCTV. Dr. Michael Holick has long been a promoter of vitamin D even at the risk of his career. He has been repeatedly attacked and lost his job at one point. He has become very cautious in his presentations on vitamin D. This video was made in 2009 and there has been much new science published since then on the advantages of vitamin D for health.
The video is about one hour long. It is very entertaining as Dr. Holick helps you to understand the science in a consumable reality. In the video Dr. Holick expresses the need to keep your serum level of 25(OH)D above 30 ng/ml. However, at the end of the video, please note that his average level is 52 ng/ml. This is the bottom of the level typically achieve by the indigenous populations along the equator. I do believe that the best levels to maintain are 60 to 80 ng/ml which is well within the norms of clinical practice of 30 ng/ml to 100 ng/ml. At these higher levels, be sure that you are getting enough magnesium as well.
