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 tested my Vitamin d level, it was 120ng/ml, I got to this level by taking 50 000 IU per day for almost 6 months. I would like to get my level lower, does taking just 5 000 IU per day allow it to get lower or is it enough to just maintain that 120ng/ml?

    I could use a little more information first. What is your weight and do you have any medical problems? I ask this because I would think taking 50,000iu a day for that long would have given you a much higher level than what you have. So I think you could cut back but without the above information, I am not sure if 5000iu will be too low.

    My weight is 177 lbs, pretty muscular, I do bodybuilding and I don’t have any medical conditions. I just wanted to see what would happen if I took mega doses of D, to be honest I didn’t notice anything in this whole time, nothing negative and nothing positive.. I don’t remember exactly how long I took 50 000 IU per day, somewhere in 4-6 months and then just 12 000 IU for a couple of months and just tested after all that and got 120ng/ml. What would your advice be to get me to 50-80ng/ml and staying there?

    Your levels were probably a lot higher and have come down being on the 12,000iu per day. At you weight I would probably do more than the 5000iu. I would do at least 6000iu but you could probably do between 6-8000iu which should put you in the 50-80ng/ml range.
    May I also suggest the following. Make sure you pay attention in the next several months to make sure “nothing negative” starts to happen. If so then maybe you have then cut back too far on your dosage. (This because you said you did not notice anything negative or positive.) Maybe you were not all that deficient to begin with and therefore did not notice anything “positive”. Do you happen to take any magnesium supplements? Vitamin D needs a lot of magnesium to process. If you do not take any then you might want to do and experiment. Get some magnesium but not magnesium oxide. Take about 200-300mg a day for a month and see if that gives you any “positives”. If you do that and it does, by all means please come back and tell me!

    Yes I take 160 mg of magnesium citrate every day and I have calculated that I get 700 mg of magnesium and 1 000 mg of calcium total per day from diet and supplements. I think I will take two weeks break from vitamin D supplements and that halves my level to 60 ng/ml and after that I will take 6 000 IU per day forever.

    Sounds like a plan.
