Vitamin D is a fat-soluble vitamin that also acts as a pleiotropic hormone. There 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.
1.VD3 oil can increase the body's absorption of calcium and phosphorus to saturate the plasma calcium and phosphorus levels.
2.VD3 oil can promote growth, bone calcification and dental health.
3. VD3 oil can increase phosphorus uptake through intestinal wall and phosphorus reabsorption through renal tubules.
4. VD3 oil maintain the normal level of citrate in blood.
5. VD3 oil can prevent the loss of amino acids through the kidney.
