Vitamin D is a fat-soluble vitamin that is responsible for maintaining and providing calcium and phosphorus in the blood by enhancing their absorption from food in the intestine and enhancing their reabsorption in the kidney. Maintaining the proper concentration of calcium and phosphorus in the blood is necessary to strengthen bone formation and provide the proper concentration of calcium and phosphorus in the bones in order to make the bones stronger.

In humans, the two main forms of vitamin D are vitamin D3 (cholecalciferol) and vitamin D2 (ergocalciferol). Vitamin D also refers to the hydroxylated metabolites of these two substances. Vitamin D2 is provided by food sources.

Since only fish and some seafood are rich in vitamin D2, most dietary vitamin D in industrialized societies comes from vitamin D-fortified foods such as milk, vegetable butter, soybean oil, and other plant-based edible oils. be made Vitamin D3 is produced in the skin after exposure to sunlight, especially ultraviolet (UVB) B rays. In this process, 7-dehydroxy cholesterol reacts with ultraviolet B rays and vitamin D3 or cholecalciferol is produced.

Deficiency of 25-hydroxyvitamin D following things such as insufficient consumption in food, avoiding sunlight, malabsorption, liver and kidney disorders, taking anticonvulsant drugs, such as phenytoin and phenobarbital (due to increased liver metabolism of vitamin D and a number of hereditary metabolic disorders) It is observed.

Vitamin D deficiency may lead to It increases blood pressure (due to increased renin production) and the risk of heart attacks.

Monocytes, macrophages and activated T and B lymphocytes have the ability to synthesize the active form of vitamin D due to the presence of alpha-1-hydroxylase enzyme, and their enzyme activity is not affected by the amount of blood calcium and parathyroid hormone, unlike the kidney enzyme. Vitamin D plays a role in the prevention of autoimmune diseases such as MS and type I diabetes through its effect on regulatory T lymphocytes.
