Does anyone have an online reference for which Vitamin D levels are normal and which are low?  There is no international consensus on this and it's a problem.  Measuring Vitamin D levels in pregnant women has been mentioned.  I would like to know about it if there is an impartial website (i.e. NOT the website of anyone selling a Vitamin D supplement or a home test kit or anything like that) with such information.

I had my own level of 25-OH-Vitamin D checked last year when having some other, unrelated blood tests drawn.  My doctor humored what I know she thought was a symptom of some kind of hypochondriacal neurosis and ordered the test on my request.  She phoned me a week later, all worried, saying I should stop taking cod liver oil because I had 'too much Vitamin D'.  She would have wanted to measure my serum calcium too, had she not just done so and found it entirely normal.  When I checked my value against a US reference it seemed to be smack in the middle of the normal range, but according to Norwegian references I was well above the upper limit of normal (still galaxies away from toxic levels and I continued right on taking the supplement and seeking exposure to sunlight when available - not that easy in this part of the world, esp with a day job).

Let me say, once again, that I have no financial interest in cod liver oil.  I just take a spoonful every morning and hope it has half the beneficial effect it is purported to!

Hope someone can point me to some user-friendly website for lab values :-)
