Hi all,

Lots of great information in this recently made available (through
pubmed) review article. It might be a really good article to print
out and take to your doctor for discussion as it provides about the
best collection of information I've seen related to dosing guidelines,
testing specifics, contra-indications, etc...

Use of Vit D in Clinical Practice:

There are many gems in this article, but note the discussion on the
prescription form of Vit D (Vit D2 or ergocalciferol) and the
resulting unnatural metabolic by-products in the 2nd to last paragraph
on page 13. Vit D3 or cholecalciferol is definitely the preferred
form according to the authors...
