        abstract = {Probiotics are live microorganisms that, when administered in adequate amounts, confer health benefits to the host. In recent years, advances in microbiome research have significantly transformed the understanding of human health, highlighting the central role of gut microbiota in physiological regulation. Probiotics are now recognized not only for their role in gastrointestinal health but also for their systemic effects on metabolic, immunological, neurological, respiratory, cardiovascular, and oncological conditions. These beneficial microorganisms act through multiple mechanisms, including modulation of gut microbiota composition, strengthening of intestinal epithelial barrier function, production of antimicrobial compounds, and regulation of immune responses. This review provides a comprehensive overview of probiotic classification, major microbial strains, mechanisms of action, and their therapeutic applications. Special attention is given to Lactobacillus, Bifidobacterium, Bacillus, Streptococcus, Enterococcus, and Saccharomyces species. Current scientific evidence suggests that probiotics represent promising adjuncts in the prevention and management of various diseases, particularly those associated with gut microbiota imbalance.},
