Nutritional yeast vs. Brewers yeast

[GreenLove]

Which of these has a better nutritional profile?

IIRC, nutritional yeast has some vitamin b12 and Brewers yeast does not. B12 is found in good quantities in animal meat (especially livers) but hard to get enough of from a vegetable based diet. Nutritional yeast can help, though I have no idea on quantities needed.
