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?
YouTube for me is the best source for anything, because the information is much more credible as people who show their face can not be lieng or paid pharma manipulators so easy.
Please tell me why am I wrong when I say that i personally think that the information on YouTube is much more credible than any written information and that lieng is not so easy there?
