If you have a question that cannot be found on this website, you can use this form to ask. However, answers to most questions can be found in our section About vitamin D, so please have a thorough read through that section before asking any questions.

Second, we ask you to use the search box in the header of this site and use key terms to try and look for the answer to your question before asking us. For instance, if you have a question about multiple sclerosis, search “multiple sclerosis” and see if there are any articles that might have some answers you’re looking for.

We cannot give personal medical advice, so please respect our policy and do not ask questions that are personal in nature. Any questions we answer are strictly informational and are not personal medical advice. Any information we provide do not replace the care and advice of your doctor.

Lastly, we receive hundreds of questions each week and do not have time to answer all of them. Thank you for understanding.

We need your help!
