Biotin (vitamin B7) what is this vitamin

Biotin or Vitamin B7 is a water-soluble vitamin that has no color. Another name is vitamin H, which means “skin”. And it’s not for nothing that the Germans call it that, because it really allows you to preserve the beauty of the skin and hair. For this reason, many cosmetologists in the world call it also the vitamin of beauty.  

Why is biotin (vitamin B7) needed in the body?

Vitamin B 7 is involved in metabolic processes involving proteins and fats. It also helps regulate carbohydrate metabolism in the body. The vitamin has a beneficial effect on the functioning of the nervous system.

Biotin allows you to control glucose levels, which is very important in the presence of sugar disease. It is an effective preventive measure against the development of diseases of the heart and vascular system.

Vitamin B7 has many other functions in the body, namely:

  • regulates sweating;
  • prevents the appearance of dermatological problems, in particular, prevents the appearance of dandruff, acne, seborrhea;
  • reduces pain in the muscles;
  • supports the functioning of the immune system at the proper level;
  • prevents the appearance of a feeling of fatigue;
  • normalizes the thyroid gland;
  • is directly involved in the production of collagen;
  • participates in the process of blood clotting;
  • stimulates appetite;
  • removes harmful cholesterol from the body.

And of course, the vitamin is extremely useful for maintaining beauty. It strengthens the nail plate, hair and makes the skin even and smooth.

Distribution of vitamin B7 in the body

To date, scientists have not been able to fully study the effect of this substance. It is only known that it really participates in most of the processes occurring in the body. It is synthesized by the microflora of the human intestine, but on condition that it is completely healthy.

Biotin is perfectly combined with almost all vitamins of group B. However, absorption of the vitamin from the outside and synthesis in the intestine becomes more difficult if a person consumes a lot of fats that have undergone heat treatment. Such food inevitably leads to a disorder of the gastrointestinal tract.

Almost instantly, the vitamin is destroyed by the action of sulphurous preservatives, these are substances labeled E221-E228.

What does biotin (vitamin B7) deficiency lead to?

The lack of vitamin B7 occurs not only against the background of taking certain medications and with certain diseases, but also due to the fact that biotin does not accumulate in the body, therefore, when changing the diet, a deficiency may occur. Lack of vitamin A can cause the following health problems:

  • severe toxicosis during pregnancy;
  • death of normal intestinal microflora;
  • pigmentation of the skin and deterioration of the general condition of the skin, hair, nails;

  • deformation of the nails;
  • increased blood sugar;
  • weight loss;
  • a constant depressive state, up to the appearance of attacks of neuroses and other mental disorders;
