Information on the latest vitamin D news and research.

Find out more information on deficiency, supplementation, sun exposure, and how vitamin D relates to your health.

I am curious to know what to do if I have very low Vitamin D level but can't seem to tolerate Vitamin D supplements.

Ask the Vitamin D Council

    The following information may or may not apply to you.
    Some people have a “hypersensitivity” to Vitamin D please see http://www.vitamindcouncil.org/further-topics/vitamin-d-hypersensitivity. The symptoms would be those of hypercalcemia.
    If you are magnesium deficient (a regular magnesium blood test will NOT tell you), then taking Vitamin D may cause symptoms. This is easily rectified by taking a magnesium supplement.
    You did not specify what happens when you take the Vitamin D, that is what symptoms do you get?

    About 1 person in 300 gets a reaction to vitamin D
    That rare reaction is due to the following 8 reasons
    Lack of Magnesium –
    Reaction to the sun (known)
    Dose size too big
    Reaction to Vitamin D2, not D3
    Reaction by the gut
    Reaction to additives, fillers, colors, etc.
    Reaction to Wool
    Extremely rare Interaction with a prescription drug
