This review highlights the historical origins of nutraceuticals, their classification into traditional and non-traditional categories, and the vast spectrum of herbal, microbial, enzymatic, and fortified components employed in modern health systems. The growing global shift toward preventive healthcare, personalized nutrition, and naturally derived therapeutic alternatives has strengthened their utility across Ayurveda, pharmaceuticals, food industry applications, and functional diets. Despite their promising benefits, limitations such as poor bioavailability, lack of regulatory uniformity, quality control challenges, and variable clinical efficacy remain significant concerns. Technological innovations in nanocarrier systems, metabolomics, nutrigenomics, and precision diet formulations continue to reshape the future of nutraceutical development. Overall, nutraceuticals hold strong potential as complementary tools to conventional medicine, advancing the vision of holistic wellness and personalized healthcare while demanding stricter regulatory surveillance and enhanced consumer awareness.
