From my review of the journal literature, 30 ng/ml is the minimum 25(OH)D concentration associated with optimal health.

    thank you for this info

    presently I am shooting for vit D levels of 100 in my patients as we feel that this will optimize results without any sig risk of over doing it

    of course occasional testing is needed to work this out
