Vitamin B12 is a very important element in the normal functioning of the human body and its role is difficult to overestimate. By the way, this is the only vitamin that can accumulate in the human liver. That is why cases of such vitamin deficiency are quite rare. Nevertheless, over the past 50 years, the number of people with cobalamin deficiency has increased significantly, which makes us think about preventive measures.
Vitamin B12 and its role in the human body . Active forms of cobalamin are involved in the transfer of hydrogen, as well as in the synthesis of the amino acid methionine. In addition, it is with its help that the level of oxygen consumption by cells increases significantly during oxygen starvation.
Vitamin B12 is able to enhance protein synthesis, and also improves the body's ability to accumulate the necessary proteins. Cobalamin is also involved in the functioning of the immune system, as it significantly improves the phagocytic ability of white blood cells. For example, in people with AIDS, the level of this vitamin in the blood, as a rule, is significantly reduced. It is also important for blood formation processes. In addition, this substance normalizes blood pressure.
Its very important function is the effect on the nervous system. For example, maintaining the necessary balance of this substance in the blood, you can eliminate insomnia, significantly increase the level of mental development, prevent depression, hysteria, and also stop the development of senile dementia.

For example, a sick person suffers from insomnia, increased fatigue, as well as short-term memory loss or confusion. Vitamin deficiency of this substance is very often observed in severe malignant anemia.
