Overview Rare Allergic reaction to vitamin D

It appears that about 1 person in 300 people has an allergic-type reaction to vitamin D within days.
   (Have no specific reference - it is just an impression from reading 12,000+ articles on vitamin D)
The allergic reaction may include itchy skin, hives, and intestinal upset.

The reaction is real, and the cause varies

Possible reasons and solutions

1. The reaction is typically due to a lack of Magnesium - Mg is required by Vitamin D
   Solution take Magnesium supplement for a week and try again
2. It might be similar to reaction to the sun - probably previously known
   Red-heads and others - try a smaller dose initially
   See also Photosensitivity (sun allergy) and vitamin D
3. Does size too big - at least initially
   Perhaps we need to start with a smaller dose, say 1000 IU, and get used to vitamin D for a week or so
4. Might be a reaction to Vitamin D2 Vets determined that D2 should not be given to any mammals
   Solution - use Vitamin D3, not D2
5. The reaction by the gut
   Try a sublingual form
   Try a gut friendly or topical form
   Try a vitamin D patch on the skin
   Try a processed form (calcitriol, etc.) - click on the chart below for details
   Try an injection (lasts longer) - click on the chart below for details
6. Reaction to the fillers (oil, etc.), additives, coloring, the gelatin capsule
   Try a pure and clean form such as by Bio-Tech Pharmacal
7. Rare reaction to Wool/Lanolin
   Try a plant form of D3
8. Extremely rare reaction to Vitamin D3 in regular/processed forms
   Use sun or UV bulb to generate Vitamin D in your skin - click on the chart below for details
9. Interaction of vitamin D with a prescription drug is very rare to have a drug reaction
10. Rare mutation of CYP24A1 gene results in Vitamin D accumulating
