    Question about Vitamin D.

    Primal Fuel
    I found out my vitamin D level was 20. Even after taking 2000iu for quite a while. I upped the dose to 10000iu a day. I can't afford another test. How long on average does it take to bring up your D levels? I burn very easily so don't get a lot of sun even though I live in Az.

    Everyone's different, but the average is 3-6 months, from what I have seen with my clients.

    Maintenance dosage is generally 1000 IUs per 25 lbs of body weight.

    Thank you Dragonfly, that's a close enough estimate for me. So at 1000iu per 25lbs, I should be taking 8000iu anyhow.

    Yes, for maintenance, but I took 12,000 IUs for 6 months to get my levels up.

    I stopped at 10,000 because the research I read said it was safe. Is there a max that shouldn't be exceeded at any one time?

    10,000 IUs is safe. 20,000 IUs is generally considered the upper limit.

    Our skin will make up to 20,000 IUs per day from sun exposure.

    However, when I feel like I am coming down with a cold, I take 40,000 IUs per day for 2-3 days. No problems. D3 get used up by stress, fighting infections, inflammation, etc.

    Make sure you are getting A & K from diet & supplement Magnesium --all are co-factors of D3.

    You may have trouble with utilizing it in the supplement form.

    You should reeeeaally get sun.

    Also take D3 with your fattiest meal of the day as it is fat soluble and this can almost double your body's ability to absorb it.
