That government commission was ultra conservative and many researchers disagreed with it.
The Vitamin D council is a very good resource.

Without testing, I believe 2000IU D3 a day was the upper limit suggested. Some places say 4000IU.
With testing use 1000IU Vit D3 daily for every 10 points needed to raise. A value of 50 is a good starting point. People with MS are often kept by their doctors at a 100 level.
I don't use supplements in summer when I get alot of sun.
