so black feather your saying probiotics dont do anything well i have a question for you ...how comes my Acne got 80 percent better i poop 2 sometimes 3 times a day even before i was lucky if i went every other day...more energy way better mood clearer thinking..and my penile troubles ...ed balls not hanging are going away...waking up with morning wood ..balls hanging ...more agressive more asertive....IF your statement is correct then the probiotics would not do anything for me and id see no change..fact is ive seen a huge change and the bigest changes started after adding kefir and real live probiotics...so i think you may be wrong in what you have stated. If they did nothign id feel no differnce i wouldnt poop more and my dick wouldnt work better....so there not working right?
