Abstract:

Currently, no less than 30-50% of the world's population have a low supply of vitamin D. According to modern concepts, vitamin D plays an important role in numerous physiological processes, turning into active metabolites in the body. Renal production of vitamin D performs "classical" functions, affects blood pressure regulation and has an immunotropic and neuroprotective effect. Extrarenal production implements other biological effects: regulation of cellular growth and differentiation, support of protein synthesis and breakdown processes, anti-inflammatory and immunomodulating properties, muscular function control, insulin secretion, blood coagulation, central nervous system activity, regulation of gametogenesis, apoptosis and embryogenesis, lowering the risk of developing autoimmune diseases
