There are many prebiotics on the market the most popular is inulin, I know some people are confused ,the difference between DWGE and inulin : Inulins are a group of naturally occurring polysaccharides produced by many types of plants, and is most often extracted from chicory, the inulins belong to a class of dietary fibers known as fructans and dozn`t contains glucozoid 2-metoxi-p-benzokinon (2-MBQ) and in 2,6-dimetoxi-p-benzokinon (2,6-DMBQ).
The DWGE has no fructans, no gluten and contains glucozoid 2-metoxi-p-benzokinon (2-MBQ) and in 2,6-dimetoxi-p-benzokinon (2,6-DMBQ) and naturally occuring oligopetisaccharides. There is also other type of prebiotic containing fructosaccharides (FOS).
All inulin-type prebiotics, including FOS, are generally thought to stimulate the growth of Bifidobacteria species. Bifidobacteria are considered friendly bacteria. This effect has not been uniformly found in all studies, both for Bifidobacteria and for other gut organisms.[8][unreliable source?] FOS are also fermented by numerous bacterial species in the intestine, including Klebsiella, E. coli[9] and many Clostridium species, which are considered less-friendly bacteria in the gut. These species are responsible mainly for the gas formation (hydrogen and carbon dioxide), which results after ingestion of FOS.
They can cause intestinal gas (flatulence), intestinal noises, bloating, stomach cramps, and diarrhea. These effects are usually mild if the dose is less than 10 grams per day.
I hope this will help to better understand why DWGE is so superior the the other prebiotics.
