Polymorphisms in the Vitamin D System and Health, 2013
Vitamin D is produced in the skin after sun exposure or obtained from food, mainly fatty fish or vitamin D supplements. For activation vitamin D must be hydroxylated in the liver to 25(OH)D and thereafter in the kidney to 1,25(OH)2D. For 1,25(OH)2D to exert its effect it has to bind to the vitamin D...
