In the first half of the twentieth century, an American biochemist patented ultraviolet irradiation of milk and other food products. This was done to enrich food products with the vitamin sunshine, which prevents rickets. It was about cholecalciferol (D3) - a compound that is synthesized under the influence of ultraviolet rays and enters the body with food.

Vitamin D3 is among the nutrients

Dietary sources of cholecalciferol are salmon, oily fish, butter, cottage cheese, egg yolks, caviar, yeast, liver, meat, corn oil, etc.

Vitamin D3 is very well sourced from the sun. Cholecalciferol contains its own provitamin (7-dihydro cholesterol), which is formed in the skin under the influence of the sun. Cholecalciferol enters the blood and liver when heated.

The synthesis of vitamin D3 is reduced by more than 60% under cloudy conditions. Vitamin D3 is also produced in the solarium, but repeated exposure is fraught with oncology.

Why do you need vitamin D3?

First of all, cholecalciferol is necessary for the body's exchange of calcium and phosphorus and also guards against the onset of rickets. Vitamin D3 helps strengthen and grow children's bones and skeleton. It also regulates stable muscle tone, and myocardial function and affects blood clotting.

Vitamin D supplementation has been shown to improve serum levels of fatty acids, cholesterol, and LDL cholesterol, reduce inflammation, and improve liver function in a variety of animal models. 

While more evidence is needed to prove the safety and effectiveness of vitamin D in humans with liver disease, these results suggest that vitamin D may be beneficial for this population.
