I can honestly say Brewer's Yeast definitely helps to increase milk production. This is that special ingredient that makes lactation cookies work. I have every intention of baking Lactation cookies or even making a smoothie so I can get those 2 tbls Of brewers yeast in, but I usually fail miserably (I don't have time for that)...What I have figured out is that I can disguise it in other foods a lot quicker. My fav is a bowl of apple sauce, and a big dollup of almond butter! Delish and good for milk production.
