My sprue bloodwork included other things, including vitamin D, which I have been taking for a year and a half and still showed a deficiency in. Dunno how that works.
A few years ago I was tested for Vitamin D deficiency- probably for the first time. I came out at the low end of the normal range- which is probably normal in the Boston area, where I live. We don’t get enough sunlight here for much of the year. My doctor prescribed a megadose of 10,000 units a day for 2 or 3 months and then retested. My levels were o.k. then, so she told me to take 1,000 units a day, which I do, in addition to the 400 units in my multivitamin.
My point is, maybe you need a higher dose- in addition to looking into the possibility that your really do have celiac disease, despite the negative test.

How much have you been taking? It might not be enough. And did you ever find out what the false-negative rate was on the celiac test? Vitamin D malabsorption is listed on the wiki page as another symptom.
2000 I.U. a day, which is what the doctor’s note on my bloodwork report suggested (she must not have looked at the list of supplements I take, or something). I don’t know the false negative rate but I can ask.
2000 IU is not very much. I suggest starting at 1000 iu per 25 pounds of body weight for light skinned individuals, and then testing and adjusting accordingly. (say, 1000 iu for every 10 ng/ml you want to increase)

And starting from there I suggest adding MOAR D until your bloodwork puts you in the mid-high range. ;)
