Notice what’s missing? Fruits and vegetables. Vitamin B12 is not found in plant foods unless they’ve been fermented. The process of fermentation exposes them to bacteria that make (or synthesize) Vitamin B12. While the human Gastrointestinal (GI) tract is full of interesting bacteria, the kind of bacteria that can produce Vitamin B12 is located way, way down the GI tract in the colon and pretty much the only thing that gets absorbed here is water.
