Your website states that vitamin D supplements should not be taken by individuals who get kidney stones: "If you have one of these medical conditions: primary hyperparathyroidism, Hodgkin’s or non-Hodgkin’s lymphoma, a granulomatous disease, kidney stones, some types of kidney disease, liver disease or hormonal disease, you should get advice from a specialist. See our Hypersensitivity page for more information" – here is the link to the page where this appears https://www.vitamindcouncil.org/about-vitamin-d/how-do-i-get-the-vitamin-d-my-body-needs/. But in an article by Dr. Cannell published on your site at this link https://www.vitamindcouncil.org/does-vitamin-d-cause-kidney-stones/, he refers to studies which showed the opposite – that vitamin D helps to prevent kidney stones. I have had a bad kidney stone episode and I want to take vitamin D supplements in the winter (I live in Canada), but this contradiction on your website is confusing. Could you please clarify? Thank you.

    The Mayo Clinic says the following:
    Kidney stones form when your urine contains more crystal-forming substances — such as calcium, oxalate and uric acid — than the fluid in your urine can dilute. At the same time, your urine may lack substances that prevent crystals from sticking together, creating an ideal environment for kidney stones to form.
    So the conflict comes in with “calcium”. If you have one of those medical issues on the “hypersensitivity” page, then it “may” cause high calcium levels or what is called hypercalcemia. Taking Vitamin D under these circumstances can cause the hypercalcemia or make it worse. So under these circumstances one has to seek medical care. Even if you have “hypersensitivity” you may still be able to take Vitamin D but calcium levels need to be monitored.
    Even if the stone was “calcium” based it does not mean you have hypercalcemia.
    So “yes” for people who have kidney stones but not the above, it is good to take Vitamin D.
    Hope this helped to clarify!
