Brewers yeast is pretty cool. Definitely something to look into for like a non-caffeine energy boost. I had an old bottle sitting around and just started taking it again yesterday. So far it's curious, I seem to remember good results from consistent use in the past. Will update on appetite. I certainly have eaten healthier last couple days, but I don't know if that's because I stopped taking my diet pills or it's the brewers yeast working.
Too soon to tell, but already feeling a healthy sort of boost.
