My brother recently started using them, after having some digestive problems after gall bladder surgery and said they greatly improved his issues. I don't have any digestive problems so to speak, just the occasional nervous stomach type issues. I do eat yogurt pretty frequently, but didn't realize that it had enough probiotics in it to be effective. At any rate, i was just wondering about them, based on my brother's feedback. i bought some generic ones last week and having been taking them for a few days now. Just trying them out...
