I found a difference the day after I started taking one called Primadophilus Reuteri made by Natures Way (found in health food stores), the only downside is it must be kept cold, at the store they keep in their fridge as well. The things I love about
it is it has guaranteed intestinal release, only one/day is needed (where I live in alberta, canada, it only costs me 29.00 for a bottle of 90 tabs which lasts me 90 days) so it's very affordable with only one/day being needed. It has also aided my severe lactose intolerance, high cholesterol and vaginal health (but it's still perfect fine for men to use of course) it states these claims on the packaging and from my experiance it holds true to it's word. It's only got some potato starch for preservations which makes it a good one cuz you don't need a bunch of fillers, sugars and junk in your probiotic.
I've been taking one everyday for the last 4ish yrs and I have to say it may be coincidence but that's the longest I have not had proctitis issues as well in my 18 yrs of having crohn's colitis, I have often had issues with proctitis at least a few times a yr but not once in the last 4ish yrs since I started taking this probiotic, like I said, it could be coincidence but whatever it is I don't care I'm just glad not to have proctitis issues for so long and hope it continues.
