I think the reason why the bloating went away for me with the probiotic was because I had a pretty bad round of infections that had left me on antibiotics & steroids for about 6 weeks -- I think that probably took out all the good bacteria in my gut -- and allowed the bad stuff to flourish -- thus the gas & bloating. I had gas & bloating nearly all the time. However -- beano and all that didn't work for me hardly at all. The rest of the diet helped my other symtoms -- but didn't touch the gas. Then I took the probiotic -- (and it has to be a good one) -- and at first it didn't seem to be doing anything... but after 3 weeks I noticed I was good. At four - I didn't seem to be having any trouble at all. Now if I eat the wrong foods (dairy -- too much fat -- too much food etc) - I will still get gas & bloating & remind myself not to do that again -but all in all I don't have any problems.
