I have been taking Align for about a month with little effect. I have IBSD and it may be making my stool firmer, but I still have tons of gas and bloating and the feeling of incomplete evacuation. A friend of mine said her gastro suggested Florastor and that helped her tremendously. I also saw Digestive Advantage at the drugtore. My question is can you take all of these at once. It seems to me if these are all good bacteria I don't see what harm it would do. I don't care if I don't know which one is working. I would continue to take all of the if I got relief.
