Below is a link to a six page analysis of the official recommendation for daily vitamin D3 supplement by Dr. Mark Hyman. He is a practicing physicians so he is working in the arena of direct information on the health of his patents.

Official Recommendation for Vitamin D3 Left Out Top Vitamin D Researcher, Mark Hyman, M.D., Dec 18, 2010, One day, vitamin D seems like the cure for everything, and the next, we are inundated with warnings about dangers and lack of science. Confusion is rampant about the Dietary Reference Intakes (DRI's) for Calcium and Vitamin D recently released from the Institute of Medicine.
I have reviewed the report carefully and gathered input from international experts on vitamin D and the clinical team at my medical center -- which includes four master's degrees in nutrition, authors of textbooks on nutrition, and international leaders in nutrition education for physicians and dietitians. Collectively we have 100 years of reviewing nutrition research and applying it with thousands of patients. Here is what I think about the new vitamin D recommendations based on a synthesis of all this information.
New Vitamin D Recommendations: Are They Enough?
Although I agree with an increase in the DRI's for vitamin D, I feel the new DRIs are overly cautious, and I am disappointed that the panel failed to address a large volume of compelling research showing the benefits of optimal vitamin D intake in so many conditions. These go well beyond bone health and include cancer, depression, imbalances in the immune system, heart disease and many others. Vitamin D is a very complex and fascinating nutrient that has multiple roles and effects in the body beyond bone health.
An important distinction to keep in mind is that the DRI's are intended as general population based guidelines. They do not differentiate or take into account a person's unique medical history, genetics, dietary intake, clinical symptomatology, environmental conditions including sunlight exposure or biochemical and nutritional assessment.
My own practice-based clinical evidence from testing thousands of individuals with the goal of optimizing vitamin D status, correlated with other biomarkers, show very positive effects on both skeletal and extra skeletal conditions. At the UltraWellness Center we routinely check vitamin D levels, monitor clinical symptoms, evaluate our patient's health status and tailor medical nutritional therapy accordingly. ... http://www.huffingtonpost.com/dr-mark-hyman/how-much-vitamin-d_b_796734.html
