You can count it if it's on the label, which it is. It's kinda high in sodium though. http://www.marmite.com/hate/nutrition/nutrition.html
Red Star Nutritional Yeast is also a reliable source. I think they recently changed the name of that to Lynside, but our bulk bin still says Red Star. (Other brands may or may not be; check labels.) I use this quite a bit, as a parmesan cheese substitute and seasoning for other things.
Also, almost all soymilks are fortified with B12, and some other plant milks.
