Prebiotics are the non-digestible compounds found in certain foods that promote the growth of beneficial bacteria already present in your gut. Probiotics are live beneficial microorganisms that you consume to directly introduce these organisms into your gut. Both prebiotics and probiotics can play a role in maintaining a healthy gut microbiome and supporting overall well-being. Combining prebiotic-rich foods with probiotic-rich foods or supplements can be a strategy for optimizing gut health.
