IBS basically involves a leaky gut, and formulations combining glutamine, NAG
and FOS/probiotics are meant for this condition.
Douglas Labs' Intestamine is one, but quite expensive. Intestamine was originally
formulated and sold by AMNI (Advanced Medical Nutrition), but since Douglas Labs
took it over, their prices have virtually doubled.
Note that it is selling under the Douglas Labs label at $ 69.20 :

RenewLife also has a good product, IntestiNew :
" Whether you have IBS, leaky gut or if your intestines have become damaged from
parasites, candida albicans overgrowth or any other ailment that affects the health
and permeability of the intestines, this product is indispensable in healing and
rebuilding the intestinal walls. L-Glutamine not only repairs the entire tract, but also
provides your body with energy as it is a very important amino acid."
