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.

I take 10000 iu D3 daily for a few years now,which has brought my level up from 18 to 55. My question is about my calcium level being about 10.2 avg since 2004. I thought the D and 100mcg K2 would bring that calcium down? I do not supplement calcium. I take 400 of magnesium and other minerals and antioxidants. Also my husband takes same amount and his bit D level is much higher.

    Normal calcium levels are anywhere from 8.5 – 10.5, so you are within the normal range. A lower calcium level does not equal better.
    I would also have thought your D level would have been higher than 55ng/ml taking 10,000iu. Weight can make a difference. Do you have any health issues that might use up Vitamin D faster than a normal person? I think genetics can also play a part.
    This is why we tell people to take 5000iu and then after about two months, get retested to make sure that amount gets you to 50ng/ml. If not then you should take more.
    Sounds like you are doing everything right to me!!!
