Vitamin D-binding protein levels likely unimportant in vitamin D status

Posted on: May 20, 2014   by  tom.weishaar@gmail.com


Last December I wrote about a study in the New England Journal of Medicine by Powe et al. that suggested the amount of bioavailable vitamin D was about the same in blacks and whites living in the United States, although it is well known that total levels of vitamin D are much lower in U.S. blacks. The study suggested, based on the bone-mineral density paradox (blacks typically have higher BMD than whites), that vitamin D status has nothing to do with the health differences between U.S. blacks and whites, although vitamin D status has been associated with racial health disparities in at least 27 other studies.

Bioavailable vitamin D is defined as 25(OH)D that is not bound to vitamin D-binding protein (DBP), a blood protein similar to the major blood protein, albumin, but much less abundant.
