Episode 217: Shining a bright light on the Vitamin D evidence

In episode 217, Mike and James level the playing field by talking about the evidence behind recommended Vitamin D levels. We then start to look at the evidence for the use of Vitamin D in a variety of conditions, starting off with rheumatoid arthritis. At the end we realize the recommendations are far stronger than the evidence – surprise, surprise.
