Try different brand: If you stay with severe vit d deficiency, you will not be healthy in the long run. Therefore do a trial of different vit d supplements to find one you can tolerate.

? Allergy to fillers: Vitamin d should not cause these symptoms and it is impossible to be allergic to vit. D in and of itself, but many pills contain a variety of fillers and binders that you might be reacting to. Read the label of the d you are taking and see what the other ingredients are and then try another brand that has different (and the least amount) of other ingredients.
