Abstract

The initial years of childhood is a crucial stage of development marked by rapid growth and maturation of the gastrointestinal system and immune function, brain growth, and establishment of musculoskeletal function. During this period, nutrition plays a fundamental role not only by providing essential nutrients but also by shaping the gut microbiota, which acts as an important regulator of digestion, metabolism, immunity, and systemic development. Increasing evidence highlights the potential of synbiotic nutrition, combining prebiotics and probiotics, as an effective strategy for maintaining a favorable intestinal environment while promoting broader developmental outcomes. Among commonly studied prebiotic compounds, galacto-oligosaccharides (GOS) have received considerable attention for their role in shaping intestinal microbial communities. They selectively stimulate beneficial intestinal microorganisms, particularly Bifidobacterium, promoting microbial balance while encouraging bacterial fermentation processes that generate health-supporting compounds, including SCFAs. Lactobacillus reuteri is a beneficial bacterial strain naturally present in the gastrointestinal tract and contributes to gut homeostasis through microbial competition, antimicrobial activity, immune modulation, and support for the structural and functional integrity of the intestinal lining. The combined biological effects produced when GOS is used together with L. reuteri create a synbiotic environment that supports better gastrointestinal tolerance and normal intestinal maturation. Beyond gastrointestinal benefits, a growing body of research indicates that intestinal microbial communities may have effects extending beyond the digestive system, involving multiple organ systems through complex communication networks, including the gut-brain axis, gut-bone axis, and gut-muscle axis. Microbial metabolites, immune mediators, and improved nutrient utilization may contribute to neurological maturation, cognitive development, bone mineralization, and muscle growth.
