The global rise in chronic inflammatory diseases has fueled an increased demand for functional beverages containing bioactive compounds with anti-inflammatory properties. This review synthesizes trends in research output, technological innovation, and consumer behavior related to such beverages from 2006 to 2025. A total of 1635 peer-reviewed articles were analyzed using bibliometric tools and content analysis. Results indicate a thirteenfold increase in publications, with China, India, the USA, and Brazil leading in research output. Key themes include polyphenols, curcuminoids, fermentation, encapsulation, and non-thermal processing. The review identifies four major research clusters: antioxidant mechanisms, metabolic and cytokine regulation, plant-derived flavonoids, and phytochemical profiling. Consumer behavior analysis reveals that taste, clean-label appeal, and health claims influence market success. While technological advances such as nanoencapsulation and high-pressure processing improve bioavailability and sensory quality, gaps persist in clinical validation and regulatory harmonization. This study offers integrated insights for researchers, industry professionals, and policymakers to guide innovation and evidence-based development of anti-inflammatory functional beverages.
