What are HMOs?

Video description

This video offers an introduction to human milk oligosaccharides (HMOs), a key component of human milk. In this introduction we look at what HMOs are, how they are formed and how their benefits are linked to their unique structures.

This video focuses on two of the most abundant and wellresearched human milk oligosaccharides (HMOs) - 2′FL and LNnT. It outlines their roles in supporting immune function, strengthening the gut barrier, and modulating microbiota, and how these mechanisms support with the dietary management of cow’s milk protein allergy (CMPA).

The Role of HMOs

This video provides a brief overview of how human milk oligosaccharides (HMOs) support immune protection — showing how they block pathogen adhesion, promote beneficial microbiota, and help modulate epithelial and immune cell responses to strengthen earlylife immunity.

The HMO Journey

This video looks at the HMO journey—decades of scientific research that have deepened our understanding of what human milk oligosaccharides (HMOs) are and how they contribute to the development of infant immunity. It highlights how this evidence base has enabled Nestlé to incorporate key HMOs into specialist infant formulas, supporting continued innovation.

The Benefits of Human Milk Oligosaccharides (HMO) on Immunity

Human milk contains bioactive components that confer protection on the newborn. These include complex carbohydrates called Human Milk Oligosaccharides (HMO). Research is revealing the full extent of the beneficial properties of HMOs.

Human Milk Oligosaccharides (HMO)

HMOs, the third solid component of human milk, are complex structures with a high potential for specific functions. HMOs and prebiotic oligosaccharides have completely different structures, which impact on their functions. Additionally to prebiotic effects, HMOs reduces adhesion of pathogens and have immune modulator effect.
