Vitamin B12

What is useful for the body of vitamin B12 and which consequences can lead its deficit. Which products contain this element and how exactly it is absorbed?

Vitamin B12 can not be called just useful, because it is vital for absolutely any person. It is possible to explain its importance for our body by the fact that only this nutrient contains cobalt – the most important trace element to maintain health.

What is vitamin B12

For the opening of Vitamin B12 it is worth thank happy case: American Dr. U. Murphy accidentally made the discovery that the use of crude liver helps to cope with the anemia in dogs.

Other scientists d. Will and D. Mainot managed to separately allocate a certain useful substance from the liver, which got the name of cyanocobalamin or vitamin B12. Later, all three scientists were awarded the Nobel Prize for their amazing discovery.

Just like many other vitamins, B12 can be in a variety of forms.

A certain amount of this substance is synthesized by the intestine, in addition, it enters the body along with the absorbent person of animal food.

Regardless of the fact that this vitamin belongs to water soluble, it can accumulate in large quantities in a healthy liver. An interesting fact should be noted: all scientists of biochemists are still amazed by the unique phenomenon of vitamin B12, the molecule of which was so difficult that it is simply impossible to recreate artificially.

Why man vitamin B12

In the human body, the cyanocobalamin performs many essential functions:

1. takes an active part in cell division;
2. Participates in the formation of red blood cells, so vitamin B12 deficiency so often causes malignant anemia;
3. takes part in the construction of nerve cells;
4. prevents fat accumulation and in the whole body and specifically in the liver;
5. has a strengthening effect on the immune system;
6. Interacting with vitamin C and defined acids, participates in protein and carbohydrate exchange.

As can be seen from the foregoing, cyanocobalamin is simply indispensable for the human body, both children’s and adult.

So, Vitamin B12 contributes to:

1. good appetite in children;
2. intensive growth of the child’s body;
3. maintaining the health of the nervous system;
4. reduction of irritability;
5. Improving concentration and memory.

In addition, incredible Vitamin is useful B12 for hair and bones, as this substance contributes to strengthening them.

If B12 is missing

As mentioned above, the Cyanocobalamin plays a very important role in the functioning of several systems of the human body at once.

Therefore, vitamin B12 deficiency can lead to very difficult consequences:

1. The destruction of myelin layers that protect nervous cells from damage. This process, in turn, is often the reason for the development of multiple sclerosis;
2. development of other nervous diseases;
3. brain deviations;
4. frequent headaches;
5. constant irritability;
6. Serious memory disorders and t.D.

To prevent all this, it is important to know which signs can indirectly indicate that in the body there is a sharp deficit of cyanocobalamin.

So, the symptoms of the lack of vitamin B12 are usually as follows:

1. Blood coagulation disorders;
2. irregular menstrual cycle in women;
3. Periodic tingling or numbness in the legs;
4. constant weakness and fatigue;
5. memory problems;
6. heart palpitations;
7. reducing reflexes;
8. inflamed language;
9. Depression and excessive nervousness.

There are a number of factors that can certainly cause a lack of cyanocobalamin in the body:

1. Various inflammatory diseases affecting the gastrointestinal tract may cause the cells that the cells cease to produce substances necessary for assimilation;
2. Inadequate secretion of gastric acid also prevents the normal absorption of cyanocobalamin;
3. Vitamin stock may simply be exhausted while taking a large number of medicines or hormonal contraceptives.

It is also worth noting that people who adhere to the fashionable strict vegetarian diet today suffer from the deficit of this compound several times more often than those who use meat.

Where does a person get in 12

Despite all of the foregoing, it is worth recognizing that the daily need of the human body in the cyanocobalamin is very small – only 3 μg per day. To prevent the health problems associated with the lack of this useful substance, each person should know where Vitamin B12. So, the best source of cyanocobalamin is considered to be food of animal origin, especially in the liver, kidneys and heart.

The large concentration of this substance is observed in seafood and sea fish (crabs, sardines, salmon, tuna, cambal and t.D.)

There are vitamin B12 and in egg yolk, milk, some varieties of cheese (Camembert, Limburg) and meat. As for the rigorous vegetarians who do not use meat, nor milk, nor eggs, then they need to replenish the lack of vitamin B12 with the help of special vitamin complexes, because no plant can reproduce it.

During accelerated heat treatment, cyanocobalamine is practically not destroyed. For example, meat can be prepared with sugar, roasting no more than ten minutes. The liver is desirable to cook no longer than seven or eight minutes, then it will almost completely save all useful substances. The absorption of B12 is ensured due to the fact that the protein of a mucoproteis contained in the gastric juice is connected to the cyanocobalamin, while forming another complex protein, which is then easily absorbed from the intestine.

In addition, adequate assimilation of B12 is inextricably linked with the level of calcium in the body.

To maintain the level of cyanocobalamin in the body at the proper level, it is necessary to include at least once a week in the diet of calf, beef or pork liver, leaving, consumed that best with fresh vegetables. It should also be conducted in the diet products containing other vitamins belonging to the group in.
