Vitamin D1

Vitamin D1 is a form of D – a compound discovered in 1913 in cod liver oil. The substance is a molecular combination of ergocalciferol and lamisterol in the ratio 1: 1. It enhances the absorption, metabolic reactions of calcium and phosphorus.

Today 5 forms of biologically active compounds, similar in function and chemical structure, are distinguished:

  • D1 – ergocalciferol + lamisterol;
  • D2, ergocalciferol, is formed directly from ergosterol;
  • D3 – cholecalciferol, produced from 7-dehydrocholesterol;
  • D4 – 22-dihydroergocalciferol;
  • D5 – Sitocalciferol, produced from 7-dehydrositosterol.

The real value for the human body are the substances D2 and D3, but do not underestimate the role of D1 for the human body.

The value of the vitamin “sunlight”

D1, like other nutrients of group D, regulates the level of calcium, phosphorus in the human body, contributes to the full formation of bone and muscle tissue. With a sufficient amount of compound, normal bone growth occurs in children, the risk of rickets, osteoporosis is reduced.

Long-term lack of vitamin D1 can lead to the development of oncology. At the same time, the patient’s appetite is getting worse, there are convulsions, vision problems, abdominal pain, insomnia.

Sources of vitamin D1

The compound in its pure form does not occur in nature and can be obtained exclusively by chemical synthesis.

The daily intake of vitamin D1 is 10 micrograms, the upper permissible level – 50 units.

Recent studies on the biological role of the compound have led to the conclusion that the lack of a substance in women increases the risk of an adverse pregnancy outcome, reduces the birth rate.
