Technically, you could if you have access to the right consortia of strains, feed them the suitable substrate, and apply good practices to avoid undesired contamination. I have yet to discover such a culture starter to buy. Have you? Considering its health importance, though, I'd be skeptical about obtaining my B12 dose through home fermentation. Questions I'd raise, "What is the B12 yield I produce in each batch? Is it consistent from one batch to another? What B12 type is produced? Is it bioavailable once ingested?" At home, we do not have a quality lab to ensure reliable production... Thoughts?
Can make my own B12 at home with fermentation or does it always have to be very technical ?
