Nutrilite Probiotic Chicory Powder Beverage Mix works in the gut by providing beneficial bacteria that travel through the digestive system and reach the intestines, where they interact with the bacteria already living there. The probiotic strains are intended to help maintain a healthy balance of microorganisms in the gut, while inulin, a prebiotic fiber, acts as food for certain beneficial bacteria, helping support their growth. Together, the probiotics and prebiotic create a more supportive environment for the gut microbiome, which can contribute to healthy digestion and regular bowel function. It’s important to note that probiotics don’t permanently “replace” your existing gut bacteria; their effects can vary from person to person.
