No, it doesn't. I haven't had a chance to really critically review the studies that are cited in that article, so I can't give an in-depth answer as to why that article is wrong. But I know that my recommendations are based on patients I have treated. And I have treated thousands of patients with parathyroid, calcium, and Vitamin D problems. That is all that I have done for the last 6 years, in fact. I've never had a patient require 8000 units of Vit D daily to get to a normal level - never. Yet this article would have me believe that 98% of people require over 8000 units to get Vit D in the normal range?! That is absurd. Anyone who has prescribed Vitamin D and watched levels knows that this isn't true. Many things published in medical literature are not valid, and not reproducible.
