From my review of the journal literature, 30 ng/ml is the minimum 25(OH)D concentration associated with optimal health. This value has been reported for pregnancy outcomes, breast cancer in case-control studies, colorectal cancer in case-control and cohort studies, cardiovascular disease, all-cause mortality rate, and agreed to in several reviews.^{1, 2, 3, 4, 5, 6, 7}

   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
