What are the functions and effects of taking B12?

The human body contains different types of vitamins, which are generally called trace elements. If trace elements are deficient, it will affect the health of the body. Vitamin B12 is a more common type in the human body, and this substance is necessary for the human body every day, but it cannot be excessive. If it is excessive, it will produce toxic side effects. If too much vitamin B12 is consumed, it will lead to folic acid deficiency in the human body.

The main physiological functions of vitamin B12

(1) Promote the development and maturation of red blood cells, normalize the body's hematopoietic function, and prevent pernicious anemia;

(2) Existing in the form of coenzymes, it can increase the utilization of folic acid and promote the metabolism of carbohydrates, fats and proteins;

(3) It has the function of activating amino acids and promoting the biosynthesis of nucleic acids, which can promote protein synthesis. It plays an important role in the growth and development of infants and young children.

(4) It is an indispensable vitamin for the healthy functioning of the nervous system and is involved in the formation of a lipoprotein in nervous tissue. As for side effects, there are very few.

Vitamin B12, also known as cobalamin or cyanocobalamin, is the latest discovered of the B vitamins. It may be damaged to a certain extent when exposed to heat, but the loss is small due to short-term high-temperature sterilization, and the loss during normal cooking process is about 30%.

Vitamin B12 is a polycyclic compound containing trivalent cobalt. Four reduced pyrrole rings are linked together to form a corrin macrocycle (similar to porphyrin), which is the core of the vitamin B12 molecule. Therefore, compounds containing this ring are called corrinoids.

The recommended daily intake of vitamin B12 is:

1. For infants aged 0-1 years, the recommended daily intake of vitamin B12 is 0.52-1.5 micrograms;

2. For children aged 1-10 years, the recommended daily intake of vitamin B12 is 2.0-3.0 micrograms;

3. For children aged 11-18, the recommended daily intake of vitamin B12 is 3.0 micrograms;

4. For pregnant women and lactating mothers, the recommended daily intake of vitamin B12 is 4.0 micrograms.

The role and function of vitamin B12

Vitamin B12 is a vitamin that is easily deficient in people with digestive tract diseases. It is also an important element indispensable for the production of red blood cells. If it is severely deficient, it will lead to pernicious anemia.

The human body requires very small amounts of vitamin B12. Vitamin B12 is mainly found in meat and can be synthesized by intestinal bacteria. Therefore, as long as the diet is normal, there is generally no deficiency. A small number of people with malabsorption should pay special attention.

The main effects and functions of vitamin B12 are as follows:

1. Promote the development and maturation of red blood cells and prevent pernicious anemia;

2. Increase the utilization of folic acid and promote the metabolism of carbohydrates, fats and proteins;

3. It can promote protein synthesis, which plays an important role in the growth and development of infants and young children;

4. Eliminate restlessness, concentrate attention, enhance memory and sense of balance;

5. It is an indispensable vitamin for the healthy functioning of the nervous system and is involved in the formation of a lipoprotein in nervous tissue.
