Impact of vitamin D deficiency on the risk of developing type 1 diabetes

According to modern concepts, vitamin D traditionally belongs to the group of fat-soluble vitamins, it is not actually a vitamin in the classical sense of the term, since it is not biologically active. Due to two-stage metabolism in the body, it turns into an active hormonal form - 1,25-dihydroxyvitamin D and has diverse biological effects due to interaction with specific receptors localized in the nuclei of cells of many tissues and organs. [9,10,11,12] In this respect, the active metabolite of vitamin D behaves like a true hormone, hence the name D-hormone. At the same time, following the historical tradition, in the scientific literature it is called vitamin D [4,1].
