Vitamin D supplements

Interesting article.  I also read in a medical journal somewhere recently (sorry I can't remember which one) that cholesterol goes up in the winter due to the lesser amounts of Vitamin D in our bodies.  It said that the higher cholesterol in this case was a normal response.  I didn't know that! 

Furthermore, is it a bad thing for vitamin D to suppress the immune system when Crohn's patients are taking so many meds to...suppress the immune system?

This article is useful because it shows how complex nutrition issues are. But we will stick with the vitamin D3 supplements because we know it is needed to help absorb calcium, because you can't get enough sun at this time of year in New Hampshire, because it seems to have a role in protecting against cancer, because my daughter's PTH rises above normal otherwise, and because other researchers believe vitamin D deficiency might predispose people to chronic disease like IBD.
