Interesting. I did not know that B12 is a bacterium, I will have to inform myself. thanks for the note. do you have a good source to explain this?
B12 is not a bacteria, just a vitamin. It is only produced by certain bacteria (found in soils, and in the guts of animals, where they produce B12).
For me it is easier described as a bacteria. Dogs & Cats have this bacteria in their fur as they lick everywhere. Humans who have contact with dogs & cats live longer & healthier.
