Even centuries after the discovery of vitamin D, there are gaps in understanding the role of its endocrine system. It is clear that vitamin D is important for stimulation of calcium absorption in the intestines in normal/low calcium intake, and, as a result, it is needed to maintain normal calcium homeostasis and bone growth. In addition, numerous pleiotropic actions of vitamin D were identified. This article contains information on vitamin D metabolism, its importance for general health, main directions of examination and optimal treatment strategy, as well as possible complications of treatment. Also, attention was paid to laboratory diagnosis as a method for determining vitamin D deficiency and controlling possible complications in vitamin D treatment.
