Synthesizing Information

A vital source of vitamin B12 is calves' liver (one pound per day), which contains such a high quantity of vitamin B12 that even citizen who lack the intrinsic factor can discharge this in enough amounts to preclude pernicious anemia (a disease caused by deficiency of this vitamin).

There is much controversy vis-à-vis the proposed plant sources of vitamin B12. Some findings suggest that fermented soya products, seaweeds (named nori), and algae such as spirulina all contain vital amounts of vitamin B12. However, pathology reveals that due to the nearnessy of compounds structurally similar to vitamin B12, termed as B12 analogues, there is mystery in distinguishing between the two forms and these cannot be utilized to satisfy dietary needs. The most prevalent view today is that plant sources of vitamin B12 are not likely to be available to humans and hence cannot be tagged as safe sources of the vitamin.

There is some ask as to either vegetarians and vegans fetch enough vitamin B12. They are at a risk of developing a deficiency syndrome because natural food sources of this vitamin are wee to animal foods. Hence, vegetarians are advised to contain a rich intake of foods fortified with vitamin B12 within their diet schedule. Good sources of this vitamin are fortified cereals, dairy products like soya milk, free-range eggs and sunflower margarines. Precise vegetarians and vegans who do not even consume plant foods fortified with vitamin B12 need to consider taking a in a supplement that contains vitamin B12 either in oral or dietary form.

There are claims that vitamin B12 can be consistently obtained from nutritional yeasts. However, one should be aware that there is no tremendous proof to validate such a claim.

Bacteria exclusively synthesize vitamin B12. Streptomyces griseus, a bacterium once view to be a yeast, was once a source of vitamin B12. Now, the bacteria Propionibacterium shermanii and Pseudomonas denitrificans have substituted it as the latest industrial sources.
