Abstract: Background/Objective: Metabolic syndrome, a global health crisis marked by insulin resistance, obesity, and dyslipidemia, necessitates novel therapeutic approaches beyond conventional symptom management. Emerging research highlights the gut microbiome as a pivotal modulator of metabolic health, with dysbiosis-characterized by reduced microbial diversity and proinflammatory shifts-implicated in disease pathogenesis. This review synthesizes evidence from preclinical and clinical studies on microbiome-targeted therapies, including fecal microbiota transplantation, designer probiotics, and synbiotics, which aim to restore microbial balance and ameliorate metabolic dysfunction. Case Report: This review synthesizes evidence from preclinical and clinical studies on microbiome-targeted therapies, including fecal microbiota transplantation, designer probiotics, and synbiotics, which aim to restore microbial balance and ameliorate metabolic dysfunction. Discussion: Fecal microbiota transplantation transfers beneficial microbiota to enhance insulin sensitivity, while probiotics and synbiotics modulate inflammation, strengthen gut barrier integrity, and stimulate metabolic regulators like glucagon-like peptide-1 and short-chain fatty acids. Mechanistically, these therapies mitigate systemic inflammation, improve glucose/lipid homeostasis, and reduce intestinal permeability linked to endotoxin translocation. Clinical trials report improved glycemic control, lipid profiles, and weight management, underscoring their multitargeted potential. However, challenges such as donor variability, lack of standardized protocols, and long-term safety concerns hinder widespread application. Personalized approaches, informed by machine learning and microbial biomarkers, alongside innovations in Clustered Regularly Interspaced Short Palindromic Repeats-based engineering and encapsulation technologies, may address these limitations. Conclusion: Despite promising outcomes, rigorous large-scale trials and interdisciplinary collaboration are essential to validate efficacy, optimize delivery, and ensure ethical compliance. In conclusion, microbiome therapies represent a paradigm shift in treating metabolic syndrome by targeting root causes, yet translating preclinical success into clinical practice demands further innovation and evidence-based standardization.
