This vitamin is actively involved in the metabolism of proteins, fats and carbohydrates in close collaboration with Vitamin C, folic and pantothenic acid. Us to have healthy nerves and we were fully prepared before daily stress He carefully helped billions of molecules folic acid in the development of choline. He gives life and stocks iron in our bodies, which are usually lacking. Over millions of years of development, this vitamin, in addition, strong friendship with Vitamin A whom he helps in the synthesis of body tissues. It provides entry carotenes in metabolism and their transformation into active Vitamin A. Finally, in cooperation with other substances, vitamin runs basic life process - the synthesis of deoxyribonucleic and ribonucleic acids. It is proteins that comprise the cell nucleus and which contain all the genetic information.
Cyanocobalamin involved in the construction of protein and fat structure of protective myelin layer.

Most recently obtained evidence that Vitamin B12 is essential for bone formation. Bone growth can occur only when in osteoblasts (cells that create bone) there was enough Vitamin B12. This is particularly important for Children and Women in menopause, which occurs due to hormonal and bone loss.
One of the main problems Vitamin B12 is the production of methionine which in our psyche conducts such feelings as kindness, love, a sense of joy. Vitamin B12, folic acid and methionine (As well as Vitamin C) Form a kind of working group, which focuses mainly on the brain and nerves (more on this in the section on Vitamin C). These "three musketeers" of metabolism involved in the development of so-called monoamines - nerve stimuli, which are made of only one amino acid and determine the state of our psyche.

Role Vitamin B12 in metabolism is determined by its participation (in the kobalaminovyh enzymes) in the protein, fat and carbohydrate types of exchange. As a source of methyl groups, cyanocobalamin normalizes (in conjunction with folic acid and Vitamin B6) Exchange of methionine prevents fatty liver, increases oxygen consumption in hypoxic conditions. Exhibits anti-atherosclerotic effect: helps reduce blood cholesterol levels and its removal from the blood vessels. Stimulates protein synthesis, normalizes the processes of growth and development. Important is the ability to Vitamin B12 regulate processes of hematopoiesis, which is associated with its participation in the synthesis of purine and pyrimidine bases, nucleic acids, the accumulation of sulfur compounds in red blood cells. Through participation in the formation of myelin sheaths of nerve cells, cyanocobalamin necessary to the functioning of the nervous system. Increasing the phagocytic activity of leukocytes and activating activity of the reticuloendothelial system, cyanocobalamin strengthens the immune defense. To assimilate it with food in your stomach, you must have a special protein - glycoprotein - the so-called "intrinsic factor" Castle. Cyanocobalamin apply at various anemias, radiation sickness, malnutrition, liver disease (hepatitis, cirrhosis), polyneuritis, radiculitis, neuralgia, migraine, skin diseases (psoriasis, photodermatosis, dermatitis, neurodermatitis), after previous infections. Deficit cyanocobalamin leads to anemia and nervous system dysfunction (weakness, dizziness, loss of appetite, etc.)
