                                Animals cannot produce vitamin B12 on their own; only certain types of bacteria and archaea can. This microbial synthesis is the central answer to the question: **Where do herbivores get their B12?** The process is a fascinating example of symbiosis and digestive adaptation in the animal kingdom.
