Vitamin B12

Vitamin B12 regulates the functioning of the nervous system (formation of myelin sheaths), circulatory system (production of red blood cells in the body) and digestive system (fat and carbohydrate metabolism and folate absorption).

Evaluation of vitamin B12 levels is performed to diagnose the cause of anemia or neuropathy (i.e., peripheral nerve disorders), and simply to determine a deficiency of this vitamin.

The test is performed from the blood.

Vitamin B12 and its role

Vitamin B12 is involved in the synthesis of proteins and nucleic acids (which go into the structure of DNA), so it is very important for proper functioning. It aids in the absorption of folic acid and the digestion of carbohydrates and fats. It plays an important role in the production of red blood cells, so its deficiency causes anemia (anemia).

Vitamin B12 helps maintain mental health and mental performance. It is essential for the nervous system, forming the envelopes of nerve fibers. It can affect bone mineral density and prevent osteoporosis. Its proper concentration promotes well-being and cognitive function.

Vitamin B12 is accumulated in the liver, from where it is further transported with the blood. Its sources are mainly products of animal origin - such as meat and meat products, poultry, cheese, eggs and fish.
