Low Vit D is linked to autoimmune disease. Can't remember if one causes the other or not, but they are linked. Rheumy wanted my level in the 60s or above.

But I read in one of my laboratory magazines that there is some 'discussion' about what normal levels should be and how it should be handled. And my lab put a lot of $$$ into testing platforms for Total Vit D and we do LOTS of them now. Beginning to wonder if Vit D is not as fashionable as it was 5 yrs ago. I've slept since reading it and don't remember all the details in the article. I'll look to see if I can find it.
