Chronic Gastroenteritis post-abdominal surgery. Enthusiastically recommended by my GI physician. In my case, does not outperform PRO-15 Advanced Strength Probiotics, which is considerably less expensive. Also, do not care for the blister-packs, though in this case, it sounds like it may be required to maintain potency. GI doc did say I could take the generic version; I won't try the generic since I wouldn't expect the generic to outperform brand name version. Everyone's different, of course, so this brand could be helpful to you personally
