Signs and effects of vitamin D deficiency

In the last century, doctors, to protect children from rickets, prescribed fish oil for them and recommended sunbathing. People did not know, and did not try to understand what the essence of such treatment was, but strictly followed the doctor’s instructions. And it helped.

A modern person who has become accustomed to delving into the essence of the problem understands that this is vitamin D. It is he who protects children from rickets. And not only from him. What is the role of vitamin D in the human body? What symptoms can determine its deficiency? And the danger of nutrient shortage?

A little bit about vitamin D and its role for humans.
Vitamin D includes a whole group of vitamins: D2, D3, D4, D5, D6. Only two of them are valuable for human health:

D2 (ergocalciferol). This substance is able to enter the body only with food. Most supplements and products contain ergocalciferol. This nutrient is not completely absorbed by the body.
D3 (cholecalciferol). To fill the deficit of this component will allow not only food, but also the effect on the skin of ultraviolet radiation. Cholecalciferol is much faster converted into the form of vitamin D necessary for the body and is absorbed almost 4 times more successfully.
Why is it needed?
For a long time, the role of vitamin D was reduced to the assimilation of calcium by the body. Therefore, it was recommended as a prevention of bone deformities (rickets). Modern scientists have reviewed the role of nutrient and significantly expanded the list of beneficial effects on the body. What is vitamin D for?

It provides many positive effects, among which are the following.
