Hi There, A bit about my history first. My mother is anglo indian and father Australian (irish descent). I think my mother may be aspergic (undiagnosed) and both parents have diabetes. When I was 20 I was diagnosed with polycystic ovarian disorder, this resulted in emergency surgery to remove a very large cyst and they also drilled out my ovaries. I have always had weak ankles and my teeth have had problems with breaking / chipping etc. I have been anaemic previously and was admitted to hospital to get an iron infusion. Recently I noticed a rapid weight gain (round 40kg) and saw the doctor. I was then diagnosed with a thyroid disorder and prescribed thyroxine. I have also been told by clinical psychologists that they think I am mildly aspergic, but I have never done the tests to confirm if their suspicions are correct. I came across this website because I was doing some reading on schizophrenia and learnt that it can be caused by a vitamin deficiency, so I wondered if there could be a vitamin deficiency in myself to attend to. On reading this site, I thought I should try Vitamin D, do you think it will assist? I noticed that you're recommending 5000 lu per day of vitamin D3, is that dose OK for me? Or should I be aiming to go higher given the above. Thanks in advance for your help.

    The odds are you probably have a Vitamin D deficiency. We usually recommend that you try and get your level tested if possible. That way you know just how deficient you are from the start. It also helps to have that starting value because if you are low and you take at least 5000iu a day your levels should increase. If you retest later and they do not increase, or increase very little then you would need to take a higher amount of Vitamin D. This is because we do recommend 5000iu a day for most people of the average weight of 150lbs. If you weigh a lot more than that, you may have to take more in order to reach what we believe research tells us is a healthy level of 50ng/ml (125nmol/l). (If you weigh a lot more than 150lbs you can let me know. I usually add at least another 1000iu to the 5000iu for every 25lbs over the 150lbs.) For most people 5000iu a day will do that. Be careful there are two measurements used to determine Vitamin D levels, ng/ml and nmol/l. Sometimes we advise people with diseases or illnesses to reach a level of around 80ng/ml. (If for any reason you cannot test, please let me know.)
    There is enough research that links low Vitamin D levels to PCOS and auto immune disorders such as Hashimoto’s Thyroiditis (hypothyroidism) and schizophrenia and Autism and diabetis.
    So I cannot promise it would cure all of the above but at the very least you will be healthier and with levels below 50ng/ml the chance for cancer increases tremendously at around 30ng/ml and below.
    I would recommend reading http://www.vitamindcouncil.org/about-vitamin-d/vitamin-d-and-other-vitamins-and-minerals/.
    Taking Vitamin D should not cause symptoms. So if you get any, you should come back and tell me!!!
    We also like to hear “success” stories.
