VDC test kit slider
I was told by my Dr. that my Vit D was low – so I have been taking 2000 iu of (Nature Made) Vit D3 for a little more than 3 months. I just had blood work and my Vit D level did not change at all. My Dr. does not have any suggestions. Although I suspect that he doesn't believe I really took the Vit D faithfully – which I did because I was hoping to get an improvement of my energy level. Do you know what could be the problem?

    Without some more information, I will have to “speculate”.
    By the timeline given, did you start the Vitamin d at the beginning of November? To not have your levels move on even the small amount of2000iu a day of Vitamin D is questionable. So either you had some “leftover” from the fall already in your system from “sunshine” and the 2000iu at least kept you from going any lower than what you already were over the winter. The other thing would be if you have any health issues, that could be using it up faster than your intake.
    So really although your doctor thinks 2000iu is a lot, it is not. Adult humans weighing an average of 150lbs need 5000iu a day in the winter. If you get outside at all in the spring/summer/fall and depending on where you live, you “may” be able to cut back over that time frame. (Notice I said “cutback and not stop”.)
    The other thing is, I did not know what your “starting” level was. If it was very low then you should have been treated with 8-10,000 iu a day for 8 weeks and then if your levels were high enough, then you could go on a maintenance dosage of 5000iu a day.
    So I believe you took the 2000iu but it wasn’t enough! If you want to fill in the missing information or have more questions, just ask.
    I also encourage everyone to read http://www.vitamindcouncil.org/about-vitamin-d/vitamin-d-and-other-vitamins-and-minerals/.
    We here at the VDC recommend maintaining “healthy” levels of 50ng/ml or higher. At levels at or below 40ng/ml, your chances of cancer and autoimmune disease rises “dramatically”.
