Also, not all bacteria produce B12. Fermented foods are not reliable because most bacteria do not produce B12. When there is actual B12 in fermented foods, it's a good sign that they were contaminated by feces at some point. And while we do have B12 producing bacteria in our digestive track, they are too far down the track for us to be able to absorb the B12.
Some people recycle B12 better than others in their systems, some people absorb it better, some people have bigger supplies of it from their animal eating days. For some, it can take many years for deficiency to develop (though for others, deficiency can develop much sooner). However, your stores will eventually deplete if you do not get enough in your diet. Please don't deplete your stores of B12 and become deficient. This is a very serious problem and it does happen.
