Earth Balance Spreads - Made Just Right

I love nutritional yeast and put it on everything from eggs to chicken, sprinkled atop salads and soups and even tossed into yogurt and oatmeal.  It's a great way to add a powerful vitamin kick to your day!

Me too... I'm crazy for it. So much in fact, that I wonder if it's possible to have too much of a good thing. Anyone know if there are negative effects to over-consuming it? 

I take a vegan vitamin with B-12 but didn't know it was so easy to get b-12 without it!  I'm new to nutritional yeast though--only tried it on popcorn so far...
