Human Milk Composition

Human milk is a complex fluid designed to nourish and protect infants. It contains all the essential nutrients—carbohydrates (mainly lactose), proteins, fats, vitamins, and minerals—tailored to a baby’s needs. Additionally, it has immune factors like antibodies, enzymes, and beneficial bacteria that help defend against infections and support gut development. Its composition changes over time to meet the evolving needs of the growing baby. Overall, human milk provides a perfect balance of nutrients and bioactive components crucial for optimal growth, immunity, and brain development in infants.
