Prunes contain soluble fiber that may act as a fuel source for probiotics, allowing them to thrive and help you maintain balance between good and bad gut bacteria. GanedenBC30 probiotic cultures are unique, as they can better survive the harsh environment in the stomach, delivering live probiotic cells more effectively to the rest of your digestive system. Prunes are naturally a good source of dietary fiber, which acts as a prebiotic, feeding the good probiotic bacteria in your system.
