Vitamin B12 is considered as an affiliate of vitamin B complex. This vitamin has an element identified as cobalt that is as well as called as cobalamin. It is solely synthesized by bacteria and is can be found chiefly in dairy product, eggs and meat. There are has research and studies that into proposed plant resources of vitamin B12. Seaweed, algae like spirulina and fermented soya products are observed to be that contain important B12. But, the available consensus in which whatever B12 is there in plant foods is to be expected to be unavailable to humans and hence these food must not depend on safe sources. Lots of vegan foods are observed to be supplemented with B12.
Vitamin B12 plays an important role in DNA synthesis and neurologic function. Deficiency can lead to a wide spectrum of hematologic and neuropsychiatric disorders that can often be reversed by early diagnosis and prompt treatment. The primary etiology for vitamin B12 (cyanocobalamin or Castle’s Extrinsic Factor) deficiency is inadequate vitamin absorption (due to deficiency of Castle’s intrinsic factor that is needed for absorption through the intestine), or a diet inconsistent with foods that provide vitamin B12, which is again the problem of many vegetarians. Vitamin B12 normally comes from animal source only.
The vitamin B12 is essential for the combination red blood cells, the growth and progress in children and the nervous system maintenance. The deficiency is can be grounds to the occurrence of Vitamin B12 neuropathy, anemia, irreversible neurological damage and concerning the degeneration of the fiber of the nerve.
The main functions of vitamin B12 are the maintenance of the nervous system for it to always be healthy and the formation of red blood cells. The B12 is essential for the fast synthesis of DNA during the division of the cell. This is particularly necessary in tissues where the cells are quickly dividing, specifically the bone marrow tissues that are accountable for the red blood cell formation. Once the B12 deficiency occurs, the production of DNA is interrupted and the abnormal cells that are identified as a megaloblasts occur. And this will result to anemia. The symptoms that are experienced in this illness are breathlessness, too much tiredness, pallor, listlessness and poor fight to infection. The other symptoms that are associated are sore tongue, smooth and menstrual disorders. The anemia might as well as occur because of the folic acid is being essential for the DNA synthesis.
B12 is as well as essential in keeping the nervous system. The nerves are surrounded by the insulating fatty sheath consisted of complex protein identified as myelin. B12 plays an essential role in the metabolism of fatty acids necessary for the maintenance of myelin. Extended B12 deficiency might as well as lead to nerve degeneration and irreversible neurological damage.
The only dependable unfortified sources of vitamin B12 are eggs, meat and dairy products. There has been considerable research in to probable B12 plant sources. The fermented soya products, algae and seaweeds have been proposed that acquire possible sources of B12. But, the study of the fermented soya products, which includes miso, tamari and shoyu, tempeh found no essential B12.
Spirulina, is an algae that is present as a dietary supplement in the form of tablet and nori, a seaweed, acquired essential amounts of B12 after the study. But, it is though that this is because of the presence of the compounds structurally the similar to the B12 that is identified as B12 analogues. These is cannot be employed to satisfy the dietary requirements. Assay methods employed to known the detect B12 are unable to differentiate between the B12 and it is analogues, analysis of the probable B12 sources might provide positive results because of the presence of these analogues.
Researchers has recommended that supposed B12 supplements like the spiruli might truly increase the danger of B12 deficiency disease, as the B12 analogues is able to compete with B12 and inhibit metabolism. The present nutritional consensus is that there are no plant foods that are able to be relied on a safe source of vitamin B12.
