I would first do some research on probiotics. From what I've seen, the only proven benefit came using them ina very certain situation which I forget completely (it was something like it helped clear up diarrhea after an antibiotic quicker or something like that). My point is they aren't cheap and you could simply be wasting money. I'm honestly not informed enough either way, but when I looked into them a few years ago, there was little to no proven benefits of using them.
