If you can only get B12 from animal sources (or so I've heard) then where does the B12 in suppliments come from?

From what I understand B12 actually comes from top soil. There are traces of B12 in vegetables, just insufficient in quantity.

Here is a good overview on B12.



A NutritionData search for vegetables highest in B6 and B12 turns up nothing except mushrooms and yeast, because B vitamins are absent from almost all veggies. In fact, they're absent from all animals too - but we'll get to that in a second.



The good news is a lot of cereals have the B vitamins in them thanks to fortification. If you're vegan or vegetarian, you probably drink soy milk, so odds are very good that you are drinking B vitamins, but do check the label to make extra sure.



Most of the vegetarian sources for B6/B12 are man-made (or man-enriched). So how did we do it before now? Surely this means that vegetarianism / veganism is all wrong, and those stupid, dirty hippies are living a lie - right?



Could be, but I don't think so. I'll quote vrg.org:

Quote:

Animals get their vitamin B12 from eating foods contaminated with vitamin B12 and then the animal becomes a source of vitamin B12. Plant foods do not contain vitamin B12 except when they are contaminated by microorganisms or have vitamin B12 added to them.



So a lot of the intake was simply from dirt! Unwashed plants. Cooked potatoes which hadn't been peeled or washed (very well), for example. The important quote from the bottom of this update is, "Neither plants nor animals make vitamin B12. Bacteria are responsible for producing vitamin B12."



What is B12 and where does it come from?



Quote:
Vitamin B12 is needed for cell division and blood formation. Neither plants nor animals make vitamin B12. Bacteria are responsible for producing vitamin B12. Animals get their vitamin B12 from eating foods contaminated with vitamin B12 and then the animal becomes a source of vitamin B12. Plant foods do not contain vitamin B12 except when they are contaminated by microorganisms or have vitamin B12 added to them. Thus, vegans need to look to fortified foods or supplements to get vitamin B12 in their diet. Although recommendations for vitamin B12 are very small, a vitamin B12 deficiency is a very serious problem leading ultimately to anemia and irreversible nerve damage. Prudent vegans will include sources of vitamin B12 in their diets. Vitamin B12 is especially important in pregnancy and lactation and for infants and children.

Do you like gums?

They are vegan!



3600% of B12 (you need a day) per gum!
