Vitamin D – in fact, it is a group of biologically active substances, which includes cholecalciferol and ergocalciferol.

What are the benefits of vitamin D?

The most important function is to maintain our skeletal system, namely, the serum levels of calcium and phosphorus in the physiological range. It is these minerals that contribute to bone growth and bone mineralization. This happens due to the receptor effect of vitamin D in the duodenum: increasing the efficiency of absorption of phosphorus and calcium, calcium reabsorption in the kidneys from the glomerular filtrate and the differentiation of osteoclast precursors in the bones.

Vitamin D deficiency can lead to bone malformations (rickets in children, osteomalacia1 in adults) and manifestations of secondary hyperparathyroidism, vitamin D increases both innate and acquired immunity by participating in the activation of immune cells and triggering the synthesis of endogenous peptides (defensins and cathelicidins) from anti-infective and anti-tumor properties. Also, a number of studies have revealed a relationship between vitamin D levels and infectious diseases. Against the background of a reduced level of vitamin D, the level of anti-inflammatory cytokines increases, which significantly affects the effectiveness of the immune response.
Insufficient levels of this vitamin increase the risk of developing acute respiratory and intestinal diseases. And treatment regimens that include replenishment of the daily norm reduce the risk of complications due to the activation of anti-inflammatory agents.

Do not forget that vitamin D3 regulates the activity of genes – an improvement in vitamin D3 contributes to a change in the severity (expression) of genes associated with the risk of developing cancer5,6 of cardiovascular diseases, autoimmune disorders.
3% of the genome is affected by vitamin D.
Vitamin D is very important for women. The low level of this vitamin in pregnant women adversely affects the implantation of the embryo. When carrying out in vitro fertilization (IVF) in patients with vitamin D3 levels in the acceptable normative corridor, the implantation ability of the endometrium was higher. There is a direct relationship between the level of this vitamin in the blood of the fetus and mother. Therefore, it is important to remember that a lack of vitamin D3 during pregnancy can adversely affect the development of the immune system, increase the risk of developing infectious diseases, and in severe forms of deficiency, intrauterine rickets of the fetus may develop8. Also, according to the study, low vitamin levels in pregnant women are associated with an increased risk of miscarriage.
