Prebiotic V a citrus-based prebiotic formula that provides flavonoid-rich polyphenols to promote a healthy gut microbiota composition while protecting the gut mucosal barrier and enhancing gut immunity. The non-fiber formula feeds the gut bacteria which subsequently nurtures gut epithelial cells while producing little fermentation, providing a safe option for individuals with small intestinal bacteria overgrowth (SIBO). Gas and bloating are common gastrointestinal symptoms for individuals with SIBO due to the imbalance and/or overabundance of bacteria in the small intestine, creating uncomfortable abdominal distress. Although providing essential fuel for the epithelial cells, traditional fiber-based prebiotics are not the ideal choice because of the gas they produce during the fermentation process, exacerbating the symptoms of individuals with SIBO. As a solution, polyphenol-based, non-fiber prebiotics can provide essential nutrients to the gut lining without producing bloating as a side effect, helping to reestablish a healthy mucosal barrier and to restore the gut terrain in individuals with SIBO.
