Vitamin B12 or cobalamin is one of the B vitamins important for maintaining health. Vitamin B12 is needed in the process convert carbohydrates, proteins and fats from food into energy.
It is also important in helping to keep the red blood cells healthy, prevent heart disease and keep the immune system to function at maximum levels. In addition, B12 is used to cover the protection of nerve cells in the body.
The main function of vitamin B12 is to form red blood cells healthy. However, all cells need B12 to stay healthy. For white blood cells, it is necessary to help ensure that the B12 in the immune system to function properly.
All nerve cells in the body also need B12 to form a protective layer of fat as they mainly at brain. If you are not enough B12 to make this protective layer can cause the brain can not function properly.
For the question of nutritional vitamin B12, it is necessary in small amounts but should be taken regularly. However, B12 is not absorbed by our body easily. Therefore, to help the body absorb B12 in the stomach should be easy to produce intrinsic factor.
Vitamin B12 is found in animal foods like eggs, liver, meat and fish. Most people take far more than what is needed by someone. If you are a vegetarian, you need vitamin B12 supplements if they can not take food from animal products.
If the body does not have enough 12 b then anaemia is the most obvious symptom. Obviously, this is due to the fact that there is not enough B12 to make healthy red blood cells. Anaemia can also be caused by the body not creating enough intrinsic factor to help absorb the B12 that is available in the food consumed.
The body tends to makes less intrinsic factor once a person reaches 50 and this will lead to less B12 being absorbed and supplements of B12 may be required. Kids are also at risk from anaemia because they may not eat the food that contain B12. Pregnant women need more B12 because the baby is absorbing B12 during the pregnancy to grow properly.
