Hi. I have recently been diagnosed (finally!!) with a vit D deficiency – 39mnol and low B12. My GP has prescribed Colecalciferol D3, 2 x 10,000 ius every day for 4 months. Is this a rather high amount please? I have suffered with fatigue, low mood, aching muscles and very painful swollen knees for a number of years. Now my feet, back, knees and wrists are painful, my wrists being very painful and swollen. A few days ago I was unable to use my left hand at all as it was so sore. I cannot sit or stand up out of a chair without supporting myself (I'm 50 years old). I have developed a large, softish lump on the top of my right wrist. I have been taking the tablets for almost 3 weeks and they have helped to reduce some of the swelling but I am still in pain and feeling stiff – paticularly if I sit for too long. My doctor has encouraged me to eat more cheese and yoghurt, salmon and nuts. I eat a very healthy diet, walk the dogs every day and I'm not over weight (in fact, my GP told me not to lose any more). I would really like to know whether a lack of vitamin D can cause such swelling and intense pain please? By the way, she's going to do a test in a few weeks to see if I'm allergic to gluten as she wonders if that's why I'm not absorbing the vit D so well. Thank you for your help and I hope the above makes sense!

    Your 39nmol/l equals 15ng/ml. We here at the VDC recommend people maintain a healthy level of 50ng/ml which is 125nmol/l. So you can see just how far you are from a healthy level. Your level is very low and can cause a lot of the symptoms you have. Since you are this sick, I would stick to the 20,000iu a day. (Yes most doctors do prescribe less than 20,000iu a day for deficiency but the amount they prescribed is not necessarily wrong.) If you think it is making symptoms worse and not better or you add new symptoms, then you need to tell me.
    You said the doctor is going to test for gluten and “she wonders if that’s why I’m not absorbing the vit D so well.” Most people and doctors do not understand just how much Vitamin D you need to take in order to have good levels. It takes an average weight person of 150lbs taking 5000iu a day to “maintain” a healthy level. If you need to get someone out of a deficit, they need to take a lot more. (There is NOT enough Vitamin D in a human diet to give them enough.)
    You should read http://www.vitamindcouncil.org/about-vitamin-d/vitamin-d-and-other-vitamins-and-minerals/. It is very important. Even if you eat well, you may want to get a magnesium supplement (no oxide) and see if it helps. Vitamin D uses a lot of magnesium to process things.
    Vitamin D levels lower than 40ng/ml (100nmol/l) and your risk for cancer and autoimmune disease increases dramatically. Did anyone ever test for Lupus or rheumatoid arthritis. Even if you actually were diagnosed with one of these conditions, the answer for recovery may still be with Vitamin D.

      Thank you so much for taking the time to respond to my queries! I really appreciate it as it’s helped to put my mind at rest regarding the high dosage. I have also started to take magnesium along with my Vit D supplement. I was tested for rheumatoid arthritis but the blood tests came back as normal (I thought that was the problem as my father has rheumatoid arthritis). I’ve been on the Vit D tablets for three weeks now and the swelling in my wrists has really improved. The lump on top of my wrist has begun to shrink too!! I still have a lot of aches and pains in my joints and muscles and tingling in my fingers but I can see a light at the end of the tunnel! I can’t wait to get my energy back. This is a great website – I’m learning so much! Thank you.
