I recommend the sachet. I feel so good that I'm on this and believe it's helping to keep me in remission -- for ulcerative colitis. I don't know if it will help irritable bowel syndrome and if you want to invest the money in it. The cheapest I've found it at is Costco. $65 for 30 sachets. A good probiotic can't hurt. This one is steep in price.
