Prebiotics Beyond the Gut: Omics Insights, Artificial Intelligence, and Clinical Trials in Organ-Specific...

Prebiotics, traditionally linked to gut health, are increasingly recognized for their systemic benefits, influencing multiple organ systems through interactions with the gut microbiota. Compounds like inulin, fructooligosaccharides (FOS), and galactooligosaccharides (GOS) enhance short-chain fatty acid (SCFA) production, benefiting neurocognitive health, cardiovascular function, immune modulation, and skin integrity. Advances in biotechnology, including deep eutectic solvents (DES) for extraction and machine learning (ML) for personalized formulations, have expanded prebiotic applications. Integrating these innovations with "omics" technologies enables precise microbial modulation, fostering personalized nutrition and precision therapies. This review examines organ-specific effects of prebiotics, highlights findings from clinical trials, and explores biotechnological innovations that enhance prebiotic efficacy, laying the groundwork for future personalized therapeutic strategies.
