Question: Where can we find B12 vitamin other than animals's products!?
Does the B12 vitamin exist in another source than animals' meat!?

Answer:

Vitamin B-12 is naturally found in meat (especially liver and shellfish), milk and eggs!. Animals, in turn, must obtain it directly or indirectly from bacteria, and these bacteria may inhabit a section of the gut which is posterior to the section where B-12 is absorbed!.

Thus, herbivorous animals must either obtain B-12 from bacteria in their rumens, or (if fermenting plant material in the hindgut) by reingestion of cecotrope f?ces!. Eggs are often mentioned as a good B-12 source, but they also contain a factor that blocks absorption!.[23]

Certain insects such as termites contain B-12 produced by their gut bacteria, in a manner analogous to ruminant animals!.[24]

An NIH Fact Sheet lists a variety of food sources of vitamin B-12!.Plants only supply B-12 to humans when the soil containing B-12-producing microorganisms has not been washed from them!.

For example, mushrooms are typically high in B-12 [25], but they are often grown in soil containing high amounts of manure and bacteria, and there is a serious question as to whether B-12 may be made by mushrooms themselves [26], and how much of it would be present after careful washing [27]!.

Vegan humans who eat only carefully washed vegetables must ordinarily take special care to supplement their diets accordingly!.

According to the U!.K!. Vegan Society, the only reliable vegan sources of B-12 are foods fortified with B-12 (including some plant milks, some soy products and some breakfast cereals), and B-12 supplements!.[28]While lacto-ovo vegetarians usually get enough B-12 through consuming dairy products, vitamin B-12 may be found to be lacking in those practicing vegan diets who do not use multivitamin supplements or eat B-12 fortified foods!.

Examples of fortified foods often consumed include fortified breakfast cereals, fortified soy-based products, and fortified energy bars!. Claimed sources of B-12 that have been shown through direct studies[29] of vegans to be inadequate or unreliable include, laver (a seaweed), barley grass, and human gut bacteria!.

People on a vegan raw food diet are also susceptible to B-12 deficiency if no supplementation is used[30]!.

Where can we find B12 vitamin other than animals's products!?
A: Fortified cereals, fortified soy/rice milks, meat substitutes/soy analogs, some brands of fortified brewer's & nutritional yeast (such as Red Star & Twinlab)!.

Sea vegetables like seaweed, dried nori, & spirulina, may contain vitamin B12, but their content varies and may be unreliable, lactic acid fermented products such as like tempeh, msio, beer & sauerkraut, but their content as well varies and may be unreliable!.

Marmite, So Delicious Dairy Free Yogurt, Manging Star foods, and other vegan store bought foods also contains B12 (Cyanocobalamin)!.

Does the B12 vitamin exist in another source than animals' meat!?
A: Of course! B12 is made from bacteria not animals, look at the sources above!
