AB  - Early childhood represents a foundational phase of human development, marked by rapid physical growth, progressive maturation of the gastrointestinal system, immune system development, and establishment of metabolic processes. During this sensitive period, efficient digestion, optimal nutrient absorption, and maintenance of gastrointestinal comfort are essential for achieving healthy growth patterns and supporting long-term health outcomes. Increasing scientific evidence indicates that the gut microbiota serves as a central mediator linking dietary components with digestive function, immune regulation, metabolic activity, and overall developmental processes.
