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.

Hello, I just got my blood checked and have a vitamin D level of 29 ng/mol. Before the test I took 1000 IE / day for about 20 days. My goal is to reach 50 ng/mol and stay at that level. Now I wonder if I just start taking 5000 IE as you recommend, I will reach 50 ng/mol sooner or later, but what then? If I just keep on taking 5000 IE "forever", I will eventually get a Hypervitaminosis, won't I? Or is it safe to take 5000 IE every day for a lifetime? Thanks a lot! :-)

    Do you think there is any “sunshine” in that measurement of 29ng/ml? Meaning if you had gotten a blood test in the middle of winter would it have been a lot lower? Probably!
    The 5000 iu a day we recommend usually gets most people weighing around 150lbs, to the level of 50ng/ml. (If you weigh more you have to take more.) At a level below 40ng/ml your risk of internal cancers and autoimmune disease rises dramatically.
    The human body uses Vitamin D constantly to repair things, keep our immune system functioning and it regulates genes.Medical science use to think it was only for bone health and they were wrong as research now shows us. So the Vitamin D does not “build up” so to speak, it is used up constantly and needs to be replenished.
    So “yes” it is safe to take 5000iu a day, forever. If you get the flu, have major surgery, trauma or severe stress, you may even want to take more than the 5000iu.Who knows how much you “use up” in those situations.
    The “official” safe upper limit to take is 10,000 iu a day or a blood level of 150ng/ml.

    Thank you very much for your quick answer, which helps a lot.

    Yes, there is some “sunshine” in that measurement, but not much.

    I will get a supplement of 5000 IE now.

    Many people say that a supplement of vitamin K2 together with vitamin D is vital, but you don’t recommend it, is that correct? I tend to do it, but like to consider your thoughts on it.

    Nevertheless I already take some magnesium for sports and fish oil capsules for omega 3 acids every morning together with the vitamin D.

    Many thanks again for your great work! :-)

    One other question comes to my mind:

    A friend has some 20.000 IE pills leftover. Her doctor told her to take 7 of these pills for 4 days like this:

    2-2-2-1

    And after that 1000 IE only in winter.

    I wonder if I could start like that as well and then take 5000 IE as you recommended.

    You will find the K listed here at http://www.vitamindcouncil.org/about-vitamin-d/vitamin-d-and-other-vitamins-and-minerals/. (By the way it’s IU not IE.)
    Your friend was probably extremely deficient and that is why the doctor told her to take them that way. Keep in mind I am not a doctor but I really do not like this method of treatment. It is not the high amount of Vitamin D I mind but I fear that people may run themselves out of the minerals that go with it and cause further symptoms.
    So if you are being “frugal” and want to use them up, then take one every four days to equal 5000iu or one every three days to equal 6600iu or one every two days to equal 10,000iu. (Make sure it is D3 not D2.)
    As you have already determined the 1000iu the doctor told your friend to take, will keep her very deficient with a low Vitamin D level. This will increase her chances of disease and sickness and poor bone health. Hope you can talk her into taking 5000iu.
    This website exists (and others like it) to dispel the myths about Vitamin D and to promote the research that tells us we (adults) all need to take a minimum of 5000iu a day and deficiency is even rampant in the summer time.

    Thanks for everything!

    I will take 10.000 IU D3 per day for only a few days now and then stay with 5.000 IU, each day together with 240 magnesium and 200 ยตg Vitamin K2 MK7. Then I will test again at the end of the year.

    I talked with my friend but she hasn’t made up her mind yet. She actually had exactly the same level as me, when her doctor prescribed the said therapy.

    I wrote IE, because in Germany it’s named IE not IU, sorry ๐Ÿ˜‰

    Your welcome Ted!
    Taking 1000iu will just make you a little less deficient but deficient none the less!

    It’s 10.000, not 1.000 ๐Ÿ˜‰

    Sorry Ted, I confused you.
    I meant your friend taking only 1000iu a day will only make her “a little less deficient but deficient none the less”.
    You stick to the 10,000 and 5000! (Unless you have an illness or disease situation, then I might recommend more Vitamin D.)

    Ah, now I get it. I will talk to her.
