Just some side notes.. In the olden days the cow manure was ploughed into the fields to grow vegetables. The vegetables did not contain any Vitamin B12, instead they were physically contaminated with manure on the surface, leaving a trace of Vitamin B12 on the unwashed vegetables. In the villages, it was customary for a father to stream the raw cow's milk into the child's open mouth while milking the cows. And yes, as a child I loved it. The raw milk was a very rich source of Vitamin B12.

Fermented soybean and algae products have been touted to have Vitamin B12. It is not true, they contain an element that mimics Vitamin B12.
