Vitamin B12 is involved in hematopoiesis, regulates carbohydrate and fat metabolism in the body. With its lack develops anemia - anemia.
Main functions
Vitamin B12 plays extremely an important role in the proper functioning of the nervous system, thus affecting on the operation of all organs. If the body lack of vitamin B12, it also leads to a deficiency of vitamin B1, even when seemingly enough in his diet. This leads to frustration, not only the nervous system, and endocrine glands, brain disease beriberi (polyneuritis), violation of the digestive system.
Psychiatrists are often surprised by how quickly helps in some cases, patients with vitamin B12. In addition, it alleviates pain in the eyes, sometimes treating infertility, particularly in men.
Vitamin B12 is involved in cell division, inherent in every living cell. The most adequate level of vitamin B12 dependent those tissues that fall most heavily: red blood cells, immune cells, skin cells, and cells lining the intestines. Although its mechanism of action is not entirely clear, it is known that vitamin B12, plays a critical role in the formation of the coating of nerves (called myelin sheath itself as a proteinaceous material called myelin) and chronic failure it causes irreversible destruction of nerves.
Participation of vitamin B12 in metabolic processes
This vitamin is actively involved in the metabolism of proteins, fats and carbohydrates in close cooperation with vitamin C, folic and pantothenic acids. To have been healthy nerves and we were fully prepared to everyday stress, vitamin B12 helps billions of molecules of folic acid in the development of choline. It updates the iron stores in the body, which is usually not enough, and provides entry carotene metabolism

and their conversion to active vitamin A. Finally, in conjunction with other substances vitamin B12 launches basic life process - the synthesis of deoxyribonucleic and ribonucleic acids. It proteins that make up the cell nucleus and which contain all the genetic information.
This water-soluble vitamin found in dairy products, egg yolks, meat, liver, kidney and fish. The content of vitamin B12 in the blood low in people suffering from Alzheimer's disease and some other psychiatric disorders.
Vitamin B12 has many important functions in the body. Together with the molecules of folic acid vitamin B12 is involved in the production of choline. It updates the iron stores in the body, which is usually not enough, and provides entry carotene metabolism

and their conversion to active vitamin A. Finally, the interaction with other substances, vitamin B12 launches basic life process - the synthesis of deoxyribonucleic and ribonucleic acids.
Unfortunately, many people suffer from a deficiency of this essential vitamin for health.
Causes of vitamin B12 deficiency
Deficiency of vitamin B12 in the body can be caused by various factors. It generally develops in people with disorders of the digestive system that prevent the normal absorption of vitamins. This may be caused by the following reasons:
- Pernicious anemia, which is accompanied by fatigue, weakness, burning tongue, stomach diseases caused by lack of gastric juice, difficulty walking, pain in the legs. It is difficult to understand how one could deliver the vitamin directly from all these hassles. In the early twentieth century, pernicious anemia was considered an incurable disease, she was treated as a type of cancer. However, on the island of Sri Lanka (Ceylon) for centuries treated pernicious anemia raw liver.
- Atrophic gastritis (thinning of the gastric mucosa) that affects more than 30% of people over 50 years.
- The consequences of surgical removal of the stomach or intestines.
- Diseases that affect the small intestine, in particular Crohn's disease (chronic granulomatous inflammation of the gastrointestinal tract), celiac disease (malabsorption of food as a result of diseases of the small intestine, which leads to intolerance glyuteina) multiplication of bacteria or parasites.
- Alcoholism.
- Autoimmune diseases such as Graves' disease
Graves' disease - when the immune system breaks down
or systemic lupus.
- Long reception of medicines, reducing acidity.
Birth control pills and a large number of different medications can deplete the entire stock of vitamin B12
. Furthermore, to assimilate it is necessary a special substance, the so-called intrinsic factor, which is produced in the body and stored in the gastric juice
. Without it, even the largest number of vitamin B12 is poorly absorbed
. There are people in the body of which he is not synthesized
. This applies mostly to elderly people, whose digestive system reduces the release of certain acids (eg, hydrochloric acid)
. If acid is not allocated in the required amount, then the substance is not synthesized, and then the iron and vitamin B12 are absorbed worse, which may lead to anemia
. In such cases, the best results give an injection of vitamin B12, not pills, which are also difficult to reconcile with iron
. However, acid berries, fruits, vegetables, apple cider vinegar maintain the desired level of acidity in the body
. Therefore, we must constantly ensure that the body receives adequate amounts of vitamins B1, B6, B2 and B12, along with natural products
.
The minimum daily intake of 3 g. Even if we eat very little meat, milk and eggs, we give the body about 15 micrograms of vitamin B12. Only pure vegetarians are at risk of losing it, so they need to take supplements of vitamin B12. Also, vitamin B12 deficiency is frequently observed in newborns if their mother - a vegetarian.
