This was my first time using nutritional yeast since starting our Vegan lifestyle.  I have to say that for me it was a miss.  I'm not sure if it is this brand or all nutritional yeast but each time I used some I would develop a headache a hour or so after eating some.  Also as they state these are "Mini Flakes", but I found them more to be powder than flakes.  You may not have the same problem I did but these are just not for me.
