Where does vitamin b12 come from?

Answer 1

indian people

Answer 2

This answer was from the question about B12 for blood types.  I had already typed it all out when the question was removed, so it was meant to fit THAT question.  Sorry, but its late I didnt feel like retyping it all, lol.

You need a new nutritionist.  Yes, your blood type can make a difference in your nutrient needs, but does not preclude you being on a vegetarian or vegan diet.  There are many plant based sources of B12, and you don't need supplements.  You can get a great source of B12 from nutritional yeast (not brewers or bakers yeast)  Nutritional yeast is a powder that can be sprinkled on foods, or can be made into a tasty cheese sauce.  Unsulphored blackstrap molasses is another source of B12 (and iron), as are raw nuts and other foods.  For a nutritionist to state that you "need" meat, shows that she is using outdated, inaccurate teachings.  Many entire cultures are vegetarian, and there nutritional needs are more than met.  Balance and knowledge is the key.  Also, contrary to what most people (and doctors and nutritionists) think, B12 is NOT manufactured naturally by animals, any more than it is by humans.  Animals are given B12 supplements in their feed.  If they can get it through THEIR diet, then you can too-without eating dead critters :).  Also, most B12 supplements are derived from animal sources.

Answer 3

B12 is synthesized by a bacterium.  It appears in animal foods because animals incubate the bacterium in their gut.  It also grows in healthy soil, but most of the soil our root vegetables are grown in are too sterile (from pesticides and chemical fertilizers) to support it.  B12 supplements are produced by the same bacterium, grown on a sterile, veg-friendly medium in a lab instead of in the gut of a cow.

Answer 4

The only reliable unfortified sources of vitamin B12 are meat, dairy products and eggs. There has been considerable research into possible plant food sources of B12. Fermented soya products, seaweeds and algae have all been proposed as possible sources of B12. However, analysis of fermented soya products, including tempeh, miso, shoyu and tamari, found no significant B12.

Answer 5

Vitamin B12 is naturally found in foods that come from animals, including fish, meat, poultry, eggs, milk, and milk products.

For vegetarians and vegans, you can find a good amount of b12 in fortified breakfast cereals. The other option would be taking pills but I find that unnecessary.

Hope I helped :)

Answer 6

Vitamin B12 can be found in cheeses (especially cheddar, parmesan and edam), fortified yeast extract such as marmite, cottage cheese and milk.

Answer 7

Vitamin B12 is actually from the dirt.  Since animals like cows eat the dirt that is on the grass, they get a lot of B12 that way.  We humans clean off the dirt from our fruits and vegetables, so we don't get Vitamin B12 in the same way.  Humans also create a small amount of B12 in their intestines, but not enough to be really usable.  That's why we are able to get it from other animals like cows and chickens (even in their milk and eggs).  You can always get supplements that are from vegan sources.

I wouldn't recommend not wiping the dirt off your veggies just because we have such a spoiled immune system, we get sick way too easily compared to most other animals (we raise ourselves in a germ-phobic manner...we don't develop any protection)
