ABSTRACT

Metabolic syndrome (MetS) is a multifactorial condition characterized by a constellation of interrelated metabolic abnormalities, including insulin resistance, central obesity, dyslipidemia, and hypertension. These components collectively contribute to a heightened risk of developing chronic liver and kidney diseases, making MetS a major global health concern. The concurrent manifestation of hepatotoxicity and nephrotoxicity in individuals with MetS significantly exacerbates disease burden and complicates clinical management. In recent years, growing attention has been directed toward the therapeutic potential of phytochemicals naturally occurring bioactive compounds found in plants. These compounds exhibit a wide spectrum of biological activities, notably antioxidant, anti-inflammatory, anti-fibrotic, and metabolic regulatory properties, which may confer simultaneous hepatoprotective and nephroprotective effects. This review comprehensively examines the current landscape of preclinical and clinical research exploring the dual organ-protective roles of phytochemicals in the context of MetS. Emphasis is placed on mechanistic pathways, including modulation of oxidative stress, inflammatory signaling, lipid metabolism, and mitochondrial function. Furthermore, histopathological and biomarker-based evidence supporting these effects is discussed. The review also highlights critical challenges limiting the translational potential of phytochemicals, such as poor bioavailability, variable safety profiles, and regulatory hurdles. Addressing these barriers is essential for optimizing their integration into evidence-based therapeutic strategies for MetS-associated liver and kidney complications.
