are two major forms of nutritional vitamin D, vitamin D2and D3. Vitamin D undergoes sequential hydroxylations,
and reaches its final active form, 1,25-dihydroxyvitamin D [1,25(OH)2D]. 1,25(OH)2D interacts with its
nuclear receptor to modulate gene expression and biological actions. The vitamin D receptor (VDR) is present
in a wide variety of cells including enterocytes, osteoblasts, and renal tubular cells. Vitamin D is crucial
for proper functions of a wide variety of organ systems, and its deficiency is highly prevalent in the general
population and also among kidney stone formers.
