I have had extremely good results using brewers yeast as a pollen 
supplement.  I have a bag I have had for several years.  I store it in a 
coolish room off my garage, but it is not refrigerated.  My reading, 
here and elsewhere, suggests that dried yeast will degrade with time if 
not refrigerated.  

Is there anyone here who can tell me, or direct me to information, what 
changes specifically take place in brewers yeast.  What amino acids are 
lost with these changes?  Also what specific balance of amino acids do 
honeybees require?
