I had great results with Ultimate Flora, found in fridgerated section of health food store, and 4Digestion by Genesis Today. Cured all of my digestive problems (GERD, hiatal hernia, IBS) very quickly. I was having problems because of a lengthy stint on antibiotics, but I am sure that everyone needs to keep healthy balance, and the drugs they are prescribing are not re-balancing peoples systems, just shutting off the stomach acid pumps, etc. Some people may need to be re-populating the good intestinal bacteria that have been killed off for various reasons. I have heard of that new yogurt someone mentioned, but not sure if it is enough to help those of us who were in really bad shape. I am so happy, back to eating as I please after almost a year of misery. I hope my story/suggestions can help someone else.
