Information on the latest vitamin D news and research.

Find out more information on deficiency, supplementation, sun exposure, and how vitamin D relates to your health.

Three weeks ago my blood test showed Vitamin D level 5ng/ml and I've been taking supplements since. Been taking 50k iU once a week, plus 1k iU daily, plus 10 mins sun exposure at 11 UV index daily. How long does it take for Vitamin D levels to become normal and what additional supplements might help?

    Below 10ng/ml and you are in the Osteomalacia range, adult rickets.
    You should read http://www.vitamindcouncil.org/about-vitamin-d/vitamin-d-and-other-vitamins-and-minerals/. It is very important.Besides calcium bones need magnesium, vitamin k, zinc, boron and silicon. Calcium is not covered in the above link but you may need some supplemental calcium. Vitamin D helps calcium absorb from the intestines. Since you are in such a low range, I am not sure if the calcium in your diet will be enough. At any point if there is not enough of a mineral, you will start to get “symptoms”. So you should let me know if you get any symptoms, you do not already have or are getting worse.
    Hopefully the 50,000iu is D3 and NOT D2. We really try and encourage taking smaller daily doses and that would translate to 7-8000iu of D3 a day. The bigger dose once a week coupled with the small daily and sunshine should still get you there.
    If the 50,000 is D3 how many weeks are you taking it for? Most doctors do at least 8 weeks. At the end they should check your levels again to make sure they have risen. We promote maintaining a minimum “healthy” level of 50ng/ml. So if for example at the end of 8 weeks you have reached that level, then you should take a maintenance dosage of 5000iu a day OR else your levels will plummet back to where you started. If they have not risen much or you have not made it to 50ng/ml, then you should let me know.
