Dr Frank Jackson, a retired gatroenterologist, has devised his own prebiotic since he finds the concept important. This link is posted for the good information regarding prebiotics and the gut microflora. It is not a recommendation of this product. This link is his 'Colon gas and flatus prevention diet' page.

A prebiotic should do three things:
...The beneficial bacteria, Lactobacillus and Bifidobacter, do not make colon gases. However, other gas-forming bacteria will metabolize prebiotics as well. So, early on there may be some excessive colon gas and flatus. The way to handle this is to start at a smaller amount of the foods or supplements. Then increase the amount every few days until a satisfactory outcome is reached...Another intersting point is that he thinks sulfides are the main culprits for smelly flatus, and that sulfate is a big source of food for them. It seems have may be persuaded by the research into sulfate-reducing bacteria in the gut.
Sulfate is the culprit. It is also a very necessary element in the diets as our body needs it for many functions. The problem with noxious flatus odor is that certain bacteria in the colon make sulfide gases in very tiny amounts, but certainly enough to be noticeable. It is pretty simple. The more sulfate you ingest, the more of it is available for colon bacteria to make sulfide gases...
