"it wouldn’t be possible to get Vitamin B12, which is only available in animal products." Marmite? http://en.wikipedia.org/wiki/Marmite http://en.wikipedia.org

  > vitamin B12 is not naturally found in yeast extract, but is added to Marmite during manufacture Perhaps it would be more accurate to say that it can't be found in plants, but it can be found in animals and it can be produced industrially.

    And for the record, "produced industrially" means farming bacteria, effectively (per Wikipedia) - it's not synthetic or derived from meat.

  And nutritional yeast etc. But first you have to get to brewing/fermenting, which isn't a year round process until you have leveled up on a bunch of other skills

    (Some) nutritional yeast is fortified with vitamin B12. It's not a natural component.
