The article presents a review of literature on the issue of vitamin D metabolism and its functions. The authors discuss the vitamins D₂ and D₃ transformations in the organism, the role of vitamin D-binding protein and the vitamin D receptors, the genetic and non-genetic effects of calcitriol which determine its various functions. The role of bile and fatty acids in the process of vitamin D absorption is shown, as well as the connection of vitamin D with phosphate-calcium metabolism.

Key words: vitamin D, 25(ОН)D, calcitriol, 1,25(OH)2D, vitamin-D-binding protein, vitamin D receptors.
