so if the multivitami was really as good as it said then it would have the fda's approval?
There are different issues for OTC's.
Your body will absorb what it needs and dicard the rest. Taking them in general is what it is and some companies say that to get you to buys their's and there is some trues and half truths involved in it all.
Take a one a day or centrum. They are much cheaper. You can buy expensive ones if you want. Again though if its not just vitamins, do one thing at a time. One herb say at a time and tell your doctor.
Iron and some vitamins can be hard on the gut, take them with a meal, if one brand bother's you try another.
On the protein try the papaya or eat natural papaya, its good for you and helps break down protein. And its cheap and has the chlorophyll in it which can help with smelly gas perhaps. Its cheaper for sure.
Hgh amounts of fruit juice can be a problem.
"Even more naturally, people who consume a large amount of fruits, juices or other processed foods enriched with fructose, can get diarrhea because it is not as easily absorbed by the bowel and goes to the colon where it pulls in water."
For c IBS this might actually helps some. But d or alternating it could be probelamtic.
IBS doesn't cause malabsorbtion and in digestioning foods, it does't interput that process, so eat a well balanced diet and try to figure out trigger foods for you and use the suggestions from Heathers book. Foods are absorbed in the stomach, IBS is mainly a problem of the sigmnoid colon, large intestines. Foods are already digested at that point.
