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.
