Answer 1

Vitamin B12 is naturally found in foods that come from animals, not plants.

What foods provide vitamin B12?

Answer 2

Soybeans and seaweed are an okay supply of B12. If you are looking for vegan or vegitarian ways to get B12 you could try theses: About 2 rounded teaspoons of large flake Vegetarian Support Formula yeast would give you enough B12 for the day. Fortified soy milk, wheat gluten, and soy beans. Very small amounts of vitamin B12 have been found in plants grown in soil treated with manure . It is not clear whether this vitamin B12 is the active form or the inactive analogue. In any case, the amounts are so small that more than 23 cups of organically grown spinach would have to be eaten every day in order to meet the adult RDA for vitamin B12. So I would stick to the pills if you are in need of B12.

Answer 3

Of all the myths, this is perhaps the most dangerous. While lacto and lacto-ovo vegetarians have sources of vitamin B12 in their diets (from dairy products and eggs), vegans (total vegetarians) do not.



Vegans who do not supplement their diet with vitamin B12 will eventually get anemia (a potentially fatal condition) as well as severe nervous and digestive system damage; most, if not all, vegans have impaired B12 metabolism and every study of vegan groups has demonstrated low vitamin B12 concentrations in the majority of individuals



Several studies have been done documenting B12 deficiencies in vegan children, often with dire consequences (12). Additionally, claims are made in vegan and vegetarian literature that B12 is present in certain algae, tempeh (a fermented soy product) and Brewer's yeast. All of them are false as vitamin B12 is only found in animal foods. Brewer's and nutritional yeasts do not contain B12 naturally; they are always fortified from an outside source.



There is not real B12 in plant sources but B12 analogues -- they are similar to true B12, but not exactly the same and because of this they are not bioavailable . It should be noted here that these B12 analogues can impair absorption of true vitamin B12 in the body due to competitive absorption, placing vegans and vegetarians who consume lots of soy, algae, and yeast at a greater risk for a deficiency



Some vegetarian authorities claim that B12 is produced by certain fermenting bacteria in the lower intestines. This may be true, but it is in a form unusable by the body. B12 requires intrinsic factor from the stomach for proper absorption in the ileum. Since the bacterial product does not have intrinsic factor bound to it, it cannot be absorbed



It is true that Hindu vegans living in certain parts of India do not suffer from vitamin B12 deficiency. This has led some to conclude that plant foods do provide this vitamin. This conclusion, however, is erroneous as many small insects, their feces, eggs, larvae and/or residue, are left on the plant foods these people consume, due to non-use of pesticides and inefficient cleaning methods.



This is how these people obtain their vitamin B12. This contention is borne out by the fact that when vegan Indian Hindus later migrated to England, they came down with megaloblastic anaemia within a few years. In England, the food supply is cleaner, and insect residues are completely removed from plant foods



The only reliable and absorbable sources of vitamin B12 are animal products, especially organ meats and eggs (17). Though present in lesser amounts than meat and eggs, dairy products do contain B12. Vegans, therefore, should consider adding dairy products into their diets. If dairy cannot be tolerated, eggs, preferably from free-run hens, are a virtual necessity.



That vitamin B12 can only be obtained from animal foods is one of the strongest arguments against veganism being a "natural" way of human eating. Today, vegans can avoid anemia by taking supplemental vitamins or fortified foods. If those same people had lived just a few decades ago, when these products were unavailable, they would have died.

Answer 4

Many of the answers already given are excellent. I am giving this answer to supply more detail on B12 function, sources, and absorbtion. Below is a link.

And the first answer given is not a joke. See the 2nd link below.

Answer 5

Vitamin B12 is naturally found in foods of animal origin including meat, especially liver and shellfish, and milk products. Eggs are usually mentioned as a good source, however they also contain a factor that blocks absorption [10]. Fortified breakfast cereals are a particularly valuable source of vitamin B12 for vegetarians and vegans. Table 1 lists a variety of food sources of vitamin B12.

Cyanocobalamin is converted to its active forms, first hydroxocobalamin and then methylcobalamin and adenosylcobalamin in the liver. A 2003 study found no significant difference in absorption for serum levels from oral vs sublingual delivery of 500 micrograms of cobalamin [11]. Injection is useful and usually necessary in cases where digestive absorption is impaired. Oral absorption is complex and requires specific intestinal transport proteins (intrinsic factor) produced in the stomach. In any case the absorption is saturated and is rate limited.

While lacto-ovo vegetarians usually get enough B12 through dairy products, it may be found lacking in those practicing vegan diets who do not use multivitamin supplements or eat B12 fortified foods, such as fortified breakfast cereals, fortified soy-based products, and fortified energy bars. Claimed sources of B12 that have been shown through direct studies[12] of vegans to be inadequate or unreliable include, nori (a seaweed), barley grass, and human gut bacteria. People on a vegan raw food diet are also susceptible to B12 deficiency if no supplementation is used[13]. The more alkaline intestines of vegans[citation needed] are able to metabolize hydroxyl cobalamin preferentially, a more efficient cobalamin than cyanocobalamin.[citation needed]

A natural vegan source of B12 is the Chinese herb Dang Gui (Angelica sinensis) [14]. The herb is used in Traditional Chinese medicine for treating anemia.[1] Other potential sources of B12 for vegans include Indonesian tempeh [2], ontjom, and other fermented food products. Spirulina, an algae that has recently gained popularity as a dietary supplement, may also contain some B12. Another source of B12 is yeast spreads, such as Marmite, which are suitable for vegetarians and vegans.

The Vegan Society and Vegan Outreach, among others, recommend that vegans either consistently eat foods fortified with B12 or take a daily or weekly B12 supplement.[15][16]

Interestingly, certain insects such as termites have been found to contain B12. [17]

Cyanocobalamin is also sometimes added to beverages including Diet Coke Plus and many energy drinks, in some cases with over 80 times the recommended intake.

Answer 6

I was reading that plants don't naturally have B12.

The most reliable source is to get fortified foods (cereal, soy milk, daily vitamin pills)
