Causes, consequences, and treatment of vitamin D deficiency in humans

Abstract

This group of vitamins consists of vitamin D2 and vitamin D3, which are synthesized in the body of some invertebrates and plants, but also in the human body. Ultraviolet rays cause vitamin D to integrate under the skin. The vitamin is transported via specific proteins to all parts of the body, where it performs numerous roles. The low level of vitamin D in blood is a current public health problem. Vitamin D deficiency is especially pronounced among the elderly and obese. Currently, vitamin D deficiency is associated with an increase in bone and cardiovascular diseases, diabetes, malignant, autoimmune and allergies diseases. That is why it is extremely essential to establish and correct the deficiency of this vitamin in a timely manner. Compensation can be done partly through food, but also through oral supplements, and in more severe cases, by intramuscular administration of vitamins.
