    Vitamin D levels not rising after high dose, why?

    i had 6 month ago a real deficiency, vitamin D was 4ng/ml. calcium blood levels started to go low, magnesium and vitamin c were not tolerated anymore. now i took over the last 4-5 month roughly 600.000 ie in weekly dosages of 35000 iu. and it is now at ~10ng/ml . and they even measured 1 day...
