Drs. Massimo Marzorati and Sam Possemiers (University of Ghent and ProDigest, Ghent, Belgium) and their colleagues employed state‐of‐the‐art human gastrointestinal tract simulations and microbiological analyses to show that Ambrotose® complex and Advanced Ambrotose® powder exerted positive prebiotic effects.* Both products exhibited good selective fermentability throughout the entire colon and positive and selective bifidogenic effects. They also demonstrated the possibility of enhancing species belonging to Bacteroidetes, a phylum recently associated with body weight management.* Study was at least partially funded by Mannatech.
