I just switched over to using this product as it is the only brewer's yeast that I can find that is organic.  Even Whole Foods only has brewer's yeast marked "natural" which means nothing.  This brewer's yeast also has a mild taste and doesn't have to be disguised, though I put it in my whey protein shake with a tablespoon of raw organic cacao and some stevia and it is fabulous.  This stuff is loaded with vitamins, minerals and amino acids and is a good source of fiber since I am allergic to chia, flax, and psyllium which don't have the nutritional value of the brewer's yeast in any case.  Excellent product.
