Agreed... also anecdotal, I have a autoimmune condition (psoriasis which includes on my face) that taking more Vitamin D helps with (so long as stress doesn't increase). I started taking 50,000 IU's to keep it under control. [I also take the K2 supplement] I also took a DNA test, and it indicated I had problems with Vitamin D absorption. A year later, my blood levels were tested and I was square in the normal range (taking 50,000 IU a day). But the two data points (from DNA and blood test) I think are important considerations.
