Vitamin B12: The Effective Health Virtues And Benefits
Wednesday, October 26,2016
You are often tired? do you have the flat mood? may be suffering from vitamin B12 deficiency. Discover its benefits and how getting enough.
Description of vitamin B12
Vitamin B complex, vitamin B12, or cobalamin, is in the form of a red crystalline compound earning him the nickname “red vitamin”. Cobalamin refers to its cobalt content, unique among vitamins.
Cobalamin is essential to the growth, cell division, the proper functioning of all body cells and balance the nervous system. It is involved specifically in the synthesis of DNA and RNA, proteins, myelin (a substance that forms a sheath around certain nerve fibers) in the formation of red blood cells, and in the metabolism of carbohydrates and lipids.
Cyanocobalamin is a synthetic form of B12 used in most supplements.
Vitamin B12 deficiency
The stores of vitamin B12 in the body are important. Symptoms attributable to deficiency may therefore take months or even years to appear and are difficult to diagnose.
B12 deficiency is often associated with a problem of absorption. B12 present in the food is bound to proteins they separated under the action of stomach acid and enzymes. Once detached from the protein, it must bind to intrinsic factor, a substance secreted by the stomach lining, to pass into the blood. The absorption of vitamin B12 is decreased if one of the two stages is slowed or prevented. People with pernicious anemia (or pernicious anemia) do not secrete the necessary intrinsic factor in the absorption of vitamin B12.
It is estimated that 10% to 30% of seniors have difficulty absorbing vitamin B12 because of low gastric acidity. US authorities recommend that people over 50 get their vitamin B12 in supplements or fortified foods in B12, because in this form, it is easily absorbed, even in low gastric acidity.
Vegans, who consume no animal products, are at risk of vitamin B12 deficiency. There is controversy about it, because the human body has significant reserves of B12 and that intestinal bacteria are able to synthesize small amounts. However, most sources agree that a diet completely devoid of B12 will eventually, after a few years, by depleting these reserves. Vegan women, pregnant or nursing should ensure enough vitamin B12 in their diet (Red Star yeast and fortified soy beverages, for example) so that their child does not exhaust their low reserves.
Vitamin B12: its role in the body
Vitamin B12 is essential to cell replication, including that of the red blood cells. It preserves the protective myelin covering of the nerves, and is involved among others in the production of substances that affect mood and psyche.
In combination with folic acid and vitamin B6, vitamin B12 helps the body to reduce the risk of suffering cardiovascular disease. It also has beneficial effects on nerves, and would be likely to prevent various neurological disorders and numbness and tingling of the extremities often associated with diabetes. Vitamin B12 may also play a positive role in the treatment of some types of depression.
Take vitamin B12 with folic acid
It is available in the form of ampoules, tablets, capsules and lozenges.
Taking a supplement must be accompanied by that of a folic acid supplement: high intake of any of these vitamins can mask a deficiency of another.
The diagnosis of pernicious anemia should be done by a doctor and regular blood tests are needed. If you are taking medication, consult your doctor before taking supplements.
Vitamin B12 or cobalamin, is the only vitamin B that stored in the body in large quantities, mainly in the liver. Low stomach acid levels or insufficient production of intrinsic factor – often related to age – can result in vitamin B12 deficiency. A deficiency can take years to break out, because the body has significant reserves.
Vitamin B12 against heart disease and depression
In most cases, the power source provides sufficient vitamin B12. But it becomes more difficult to assimilate after fifty. Or a disability Even slight increases risks of cardiovascular problems and depression.
Vitamin B12 is used to:
Prevent a particular form of anemia called pernicious.
Reduce the risk of cardiovascular disease.
Relieve nerve pain, and numbness and tingling of the extremities.
B12 deficiency causes fatigue, depression, numbness and tingling of the extremities due to nerve disorders, muscle fatigue, confusion and memory loss. Hence the importance of using supplements, if you are concerned that your diet may not provide you enough.
Against neurological and Immunity
There is often low vitamin B12 levels in patients with Alzheimer’s disease, but there is no indication whether this deficiency contributes to the disease or results. Research shows that adequate intake of B12 enhances immune responses of older people and could mitigate the loss of hearing and tinnitus.
Anyway, it is a nutritional element needed for a healthy immune system. Some studies suggest that vitamin B12 may delay the time between HIV infection and the development of AIDS, but this remains to be verified.
The recommended dose
The recommended daily intake is 2.4 micrograms.
To prevent anemia related to a strict vegetarian diet, 5-10 mcg daily. For older people, a supplement of 10 to 25 micrograms per day would be beneficial.
Usage tips :
Take once a day, preferably in the morning or during a meal. High doses may color urine red, so do not worry.
Deficiency and food
If deficit contribution:
This condition can develop into dementia or pernicious anemia, both reversible provided they are treated early. Insufficient production of intrinsic factor requires therapeutic doses much higher (of the order of 1000 mg per day). Taking vitamin B12 injections as prescribed by the doctor is often necessary.
If excess contribution:
The excess is excreted in the urine.
The animal foods are the main source of vitamin B12, whether meat or fish, offal or shellfish, eggs, cheese, milk or dairy products. Beer yeast and algae also contain in minor amounts. Note that cereals are often fortified with this vitamin.
Other useful information
An egg or a bowl of milk provides more than 25% of the recommended daily intake of vitamin B12. A dish of meat or fish: 100%.
Elderly people with mild vitamin B12 deficiency would not derive the maximum protection of the vaccine against pneumonia. A study of 30 elderly people showed that they produced, after vaccination, fewer antibodies against the bacteria responsible for pneumonia when their reserves were low in vitamin B12, which made them more vulnerable to disease.
Number of elderly people suffer from deficiencies in vitamin B12. Age sometimes causes atrophic gastritis which reduces the production of gastric juice as well as intrinsic factor, resulting in a decline of assimilation. When provided through supplements or fortified foods, it is better absorbed by the body, because it does not require stomach acid for separation of food proteins.
The level of vitamin B12 also decreases if ulcer, Crohn’s disease, or other gastrointestinal diseases, chronic dyspepsia and drop, and with the outlet of antiepileptic drugs and birth control pills. Alcohol abuse harms its absorption.
