Dr. John Kalns and colleagues (Hyperion Biotechnology, Inc., San Antonio, TX) conducted an in vitro study demonstrating that human fecal bacteria can partially break down Advanced Ambrotose® powder and two of its constituents (aloe vera gel polysaccharides and arabinogalactan). Bacteria identified that could best compete for these polysaccharides were Enterococcus species (a species that is a popular probiotic in some countries). Study was at least partially funded by Mannatech.
