Кобаламин – «кровотворец», защитник нервов и всего организма

Everyone knows that the body needs vitamins every day to function properly. One of these vitamins is B12.

Vitamin B12 – it is a very complex and valuable vitamin, which is extremely important for the normal development of nerve cells and red blood cells. When vitamin B12 (or cobalamin) is deficient, health problems such as megaloblastic anemia occur.

Red blood cells are formed in the bone marrow, but even with a slight deficiency of vitamin B12 (cobalamin), their shape is incorrect, they are not sufficiently formed to perform the main function – carry oxygen to organs and tissues.

Like all other B vitamins, vitamin B12 plays an important role in converting fats, proteins and carbohydrates into energy. It improves concentration and memory, helps in the treatment of diseases of the nervous system, and protects against tumors. Also, vitamin B12 reduces the level of homocysteine ​​– an amino acid that damages artery walls and increases the risk of heart disease.

In addition, vitamin B12 improves appetite, prevents the development of anemia and relieves discomfort before and during menstruation. Vitamin B12 is necessary for the production of myelin, which forms the protective sheath of nerves and is involved in the synthesis of DNA and RNA.

Vitamin B12 in foods and the body's daily requirement for cobalamin

As a rule, a person receives sufficient amounts of vitamin B12 by eating animal products: veal, pork (especially in the liver and kidneys), as well as fish, oysters, milk and eggs. It will not be possible to satisfy the body's need for cobalamin alone with plant-derived products due to too low a content of B12. That is why vitamin B12 deficiency is often observed in vegetarians.

The body's daily requirement for vitamin B12:

  • adults – up to 3 mcg per day;
  • women who are breastfeeding – 2.8 mcg per day;
  • pregnant women – 2.6 mcg per day;
  • children from 14 years old – 2.4 mcg per day;
  • children from 9 to 13 years old – 1.8 mcg per day;
  • children from 4 to 8 years – 1.2 mcg per day;
  • children from 1 to 3 years old – 0.9 mcg per day.

Lack of vitamin B12 can also be caused by disorders in the stomach and gastrointestinal tract. If you have symptoms of vitamin B12 deficiency, you should contact your doctor who will conduct appropriate tests and give recommendations on nutrition and / or vitamin B12 supplementation.
