"Scientific Controversies" Forum on Vitamin D: A Lot of Discussion, Little Agreement

As is clear from a number of our recent posts, there's some long-brewing controversy in academic and public health circles about the potential benefits and risks of raising the recommended daily amounts of vitamin D.  One main camp believes that there is pretty solid evidence that daily vitamin D intakes of 1000 - 2000 IU could have significant health benefits - lowering the risk of osteoporosis, heart disease, cancer, even early death.  The other main camp believes that the current evidence only backs bone-health benefits, which come at lower daily amounts of vitamin D, and that other benefits have yet to be demonstrated.

Both of these camps, and a couple ancillary ones, are captured in this video forum hosted by our colleagues at the Harvard School of Public Health, featuring among others, Dr. JoAnn Manson and Dr. Walter Willett.  

For anyone interested in the topic, and scientific argument, it's worth a viewing:  Boosting Vitamin D: Not enough or too much?
