There is a man named Jordan Rubin who had IBS and completely healed himself through nutrition. (He came very close to death). He has a company called Garden of Life that offers nutritional supplements and is available at health food stores, as well as The Vitamin Shoppe. You can google him and look at his website. I highly recommend his books. The information on diet and nutrition is excellent. FYI I do not have IBS, but have a friend who does and greatly benefitted from Jordan's information. I think it is good information for everyone. Best Wishes! I know it can be a hard thing to live with.
