okay I checked them out but I need something tonight, this is what I found at Target near me. will it work?There are cheaper options out there that work just as well, if not better. I believe that in the article posted above, (https://www.backyardchickens.com/threads/nutritional-yeast-vs-brewers-yeast.1393856/) the author said that nutritional yeast has more niacin. 1lb of nutritional yeast from NOW on amazon is about 13$. Good luck!
