Probiotic and synbiotic dairy foods have gained substantial attention due to their proven contributions to gut health, immunity, metabolic balance, and overall well-being. This review provides an updated overview of probiotics, prebiotics, and synbiotics, along with their historical development and scientific definitions. Dairy matrices such as milk, yogurt, and cheese offer nutrient-rich environments that enhance the viability and functional performance of probiotics during processing, storage, and gastrointestinal transit. Market trends indicate increasing consumer interest in clean-label, minimally processed, premium, and microbiome-focused products, which is driving rapid growth in the functional dairy sector. Technological challenges including probiotic survival, encapsulation efficiency, formulation stability, fermentation compatibility, and packaging limitations remain key obstacles to product optimization. Emerging technologies such as next-generation probiotics, plant-fiber-enriched synbiotics, CRISPR-based strain engineering, high-pressure processing, and intelligent packaging offer promising avenues for improving probiotic stability and efficacy. Future developments in personalized nutrition, multi-strain synbiotic systems, dairy-based nutraceutical beverages, and regulatory harmonization are expected to shape the next phase of innovation in this field. Overall, probiotic and synbiotic dairy foods hold strong potential as effective, consumer-friendly functional foods, provided that scientific, technological, and regulatory challenges are adequately addressed.
