I love Jarrow brands. They have high strain counts, and they have some that are in blister packs so you don't have to refrigerate them. You can also find them locally or online. I usually buy online when I see deals on the different vitamin/health store websites.

I don't know if they help, per se, but they aren't that expensive and I used to have so many stomach issues. Diet change, the surgery, et al, may have fixed it...however, overall health starts in the gut. I swallow one every night before I go to bed.
