What is vitamin B12 called?

Vitamin B12, also known as cobalamin and cyanocobalamin, is less common and can be seen in patients with gastrectomy, patients with autoimmunity in gastric parietal cells, the elderly, and patients with atrophic gastritis.

Clinical manifestations of vitamin B12 deficiency:

1 Pernicious anemia: When B12 is deficient, it leads to DNA synthesis disorders in red blood cells and induces megaloblastic anemia.

2. Nervous system damage: vitamin B12 deficiency can cause patchy and diffuse nerve demyelination, and neurological symptoms such as mental depression, memory loss, and tremor of limbs may occur.

3 Causes hyperhomocysteinemia, which increases the risk of cardiovascular disease and can cause neurological damage.

Prevention of deficiency: Reasonable nutrition, balanced diet, and appropriate intake of vitamin B12-rich foods.

Dietary vitamin B12** is found in foods, with meat, organ meat, fish, poultry, shellfish and eggs being the main foods**, and milk and dairy products to a lesser extent. Vitamin B12 is largely absent from plant-based foods.

Vitamin B12 is also known as cobalamin.

Vitamin B12, also known as cobalamin, is the only vitamin that contains metallic elements. Vitamin B12 in nature is synthesized by microorganisms, and higher animals and plants cannot make vitamin B12. Vitamin B12 is the only vitamin that needs the help of an intestinal secretion (endogenous factor) to be absorbed.

Some people lack this endogenous factor due to gastrointestinal abnormalities, and even if the diet is sufficient, they will suffer from pernicious anemia. Vitamin B12 is largely absent from plant foods. It stays in the intestine for a long time, taking about three hours (most water-soluble vitamins only take a few seconds) to be absorbed.

The main physiological function of vitamin B12 is to participate in the production of bone marrow red blood cells and prevent pernicious anemia; Prevents damage to the nerves of the brain. Vitamin B12 is the latest of the B vitamins to be discovered so far. Vitamin B12 is a polycyclic compound containing 3-valent cobalt, and 4 reduced pyrrole rings are linked together to form a large cyclic (similar to porphyrin), which is the core of the vitamin B12 molecule.

Vitamin B12 has many effects on the human body:

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

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

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

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

5. It is an indispensable vitamin for the sound function of the nervous system and participates in the formation of a lipoprotein in nerve tissue.

The main functions of vitamin B12 in the body are: 1. Promote methyl transfer, promote the development and maturation of red blood cells, make the human hematopoietic function in a normal state, and prevent pernicious anemia; 2. Maintain the health of the nervous system; 3. In the form of coenzymes, it can increase the utilization rate of folic acid and promote the metabolism of carbohydrates, fats and proteins. Vitamin B12 is a general term for vitamin B group chemicals with a cobaltin ring structure, and there are four vitamin B12 families, namely cyanocobalamin, hydroxocobalamin, adenosylcobalamin, and methylcobalamin, among which methylcobalamin and adenosylcobalamin have direct biological activity and can directly participate in biochemical reactions in vivo.

The human body cannot produce vitamin B12 on its own, and can only be supplemented by diet or medication.

Vitamin B12 prevents anemia and supports nervous system health.

What are the benefits of vitamin B12?

It is the only vitamin in the human body that contains metallic elements. It can be synthesized by microorganisms, but it is not easy to be absorbed, and it is often supplemented to prevent pernicious anemia, protect brain nerves, and improve sleep.

The elderly, pregnant women, people who don't like meat, people who like to drink alcohol, people who are taking gastroesophageal reflux medications, and people who have immune system problems are all suitable people for supplementation.

Does vitamin B12 have ***?

Patients with hypokalemia and hyperuricemia may experience adverse reactions after taking it. However, in general, the safety profile is higher and there are fewer adverse reactions.

The role of vitamin B12 is a vitamin required by the human body for normal physiology, which can help the body's metabolism and improve sleep quality. It helps relieve pain in neuromuscular joints, etc., and is mainly used to prevent vitamin B12 deficiency.

For the fire, vitamin supplementation.

Promote the development and maturation of red blood cells, make the body's hematopoietic function in a normal state, and prevent pernicious anemia; Maintain nervous system health; In the form of coenzymes, it can increase the utilization of folic acid and promote the metabolism of carbohydrates, fats and proteins; It has the effect of activating amino acids and promoting the biosynthesis of nucleic acids, which can promote the synthesis of proteins, and it plays an important role in the growth and development of infants and young children; Metabolize fatty acids so that fats, carbohydrates, and proteins can be properly used by the body.

B12 vitaminsMany foods such as beef, salmon, and organic yogurt are rich in vitamin B12, and many dietary nutrition experts have to eat more of these foods rich in vitamin B12 in normal times. Because of the efficacy of B12 vitamins, its efficacy is more prominent.

B12 vitaminsFirst, vitamin B12 can effectively promote the repair process of the brain nervous system, so that everyone can maintain a healthy nervous state, especially the elderly, their brain capacity will continue to shrink, at this time, it is best to eat more vitamin B12-rich foods, because this can effectively prevent brain atrophy in the elderly. Second, it can effectively improve the state of the human body and round heart, you know, there are many Western medicines that have incorporated vitamin B12. Third, if you eat more foods rich in vitamin B12, it can effectively promote the digestion of the human body, because vitamin B12 can make the synthesis process of digestive enzymes in the human stomach faster, and there are more digestive enzymes.

So bloating will be far away.

If you feel that it is troublesome to eat a large number of these foods rich in B12 vitamins every day, you can also choose to buy some vitamin B12 soft capsules directly, and you can also see the above effects if you insist on eating one capsule a day.

1. Promote the development and maturation of red blood cells, make the hematopoietic function of the body in a normal state, and maintain the health of the nervous system.

2. In the form of coenzymes, it can increase the utilization rate of folic acid and promote the metabolism of carbohydrates, fats and proteins.

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

4. Metabolize fatty acids, so that fats, carbohydrates and proteins can be properly used by the body.
