Over the years, metabolic syndrome (MetS) has emerged as one of the most significant public health challenges, driven by the global increase in obesity, physical inactivity, unhealthy dietary patterns, and population aging. Ellagitannins are a class of hydrolysable tannins that have emerged as promising natural bioactive compounds, owing to their broad spectrum of biological activities. Increasing evidence suggests that some ellagitannins and their metabolites modulate several pathogenic mechanisms underlying metabolic syndrome, including oxidative stress, chronic inflammation, insulin resistance, endothelial dysfunction, and dysregulated lipid metabolism. This work reviews the pharmacological activities and therapeutic prospects of ellagitannins in the management of metabolic syndrome-related disorders. It further provides a critical and comparative analysis of the pharmacological profiles of reported ellagitannins, offering insights into their therapeutic efficacy and potential synergistic applications in the management of MetS-related disorders. Overall, Punicalagin and Geraniin currently possess the strongest preclinical evidence, supported by multiple independent studies employing both cellular and animal models that consistently demonstrate beneficial effects across several components of MetS. Chebulagic acid, Corilagin, Chebulinic acid, and Punicalin also show considerable promise but require further validation in diverse experimental systems. Potential synergistic interactions among ellagitannins when administered in combination should be investigated for enhanced therapeutic efficacy and broader multifaceted pharmacological effects.
