Gut Microbiota-Targeted Therapeutics for Metabolic Disorders: Mechanistic Insights into the Synergy of Probiotic-Fermented Herbal Bioactives
Abstract
Gut microbiota dysbiosis is intricately linked to metabolic disorders such as obesity, type 2 diabetes mellitus (T2DM), hyperlipidemia, and non-alcoholic fatty liver disease (NAFLD). Traditional Chinese medicine (TCM), particularly when combined with probiotic fermentation, offers a promising therapeutic strategy by modulating microbial balance and host metabolism. This narrative review synthesizes current research on probiotic-fermented herbal bioactives, focusing on their mechanisms in ameliorating metabolic diseases. Probiotic and bioactive compounds (e.g., berberine, polysaccharides) are highlighted for their roles in enhancing intestinal barrier function, regulating microbial metabolites like short-chain fatty acids (SCFAs), and reducing inflammation. Fermentation techniques improve the bioavailability of TCM components while reducing toxicity, as seen in fermented Salvia miltiorrhiza and Rhizoma Coptidis. Despite promising results, challenges include the complexity of microbiota-host interactions and variability in TCM standardization. Future directions emphasize integrating multi-omics technologies and personalized approaches to optimize probiotic-fermented TCM therapies. This review underscores the potential of combining traditional herbal wisdom with modern biotechnology to address metabolic disorders, which pose significant global health challenges, through a "gut microbiota-metabolism" axis. Emerging evidence highlights the critical role of gut microbiota…
