What are Human Milk Oligosaccharides?
- Human milk oligosaccharides, or HMOs for short, are oligosaccharides that are naturally found in breast milk.Its concentration is approximately 5–20 g/L, making it the third most abundant solid component in breast milk, surpassed only by lactose and fat.
- Human milk oligosaccharides are a mixture formed by the combination of five basic monosaccharides, centered around lactose, through various bonding arrangements.HMOsare not digested by the gastrointestinal tract, but they can be utilized by microorganisms in the gut.
- HMO Classification (based on structure): Neutral fucosylated HMOs, neutral non-fucosylated HMOs, and acidic sialylated HMOs. Among these, the most representative and abundant is 2’-Fucosyllactose (2’-FL).
- Human Milk Oligosaccharides are primarily used in infant and toddler formula products.It plays an important role in the growth and development of children.

No. Human Milk Oligosaccharides (HMOs) are primarily determined by the mother’s genetics; however, factors such as the stage of lactation (with the highest concentrations found in colostrum), maternal lifestyle, dietary habits, gestational age, and geographical location also contribute to their variation.
Detection methods primarily include capillary electrophoresis, high-performance liquid chromatography, high-performance anion-exchange chromatography, hydrophilic interaction liquid chromatography, liquid chromatography–mass spectrometry, and nuclear magnetic resonance.
Five monosaccharides (glucose, galactose, N-acetylglucosamine, fucose, and sialic acid).
HMOs enhance intestinal function through a three-pronged approach:
Nourishing (selectively providing nutrients to beneficial bacteria)
Protective (weakening the impact of harmful bacteria on human cells)
Strengthening (reducing the adhesion of harmful bacteria to human intestinal cells)
Benefits of Human Milk Oligosaccharides
- Human milk oligosaccharides can regulate the human gastrointestinal microbiota.As an ingredient for gut health, it functions as a targeted prebiotic, providing a growth advantage to specific beneficial bacteria. For instance, it can boost the proportion of *Bifidobacterium* to as high as 60–80%.
- Human milk oligosaccharides are natural immune guardians.As an immune-supporting component, human milk oligosaccharides have anti-adhesion effects.It can effectively reduce the risk of pathogens colonizing the gut and triggering infections.For example: Norovirus.
- Human milk oligosaccharides can reduce the risk of necrotizing enterocolitis (NEC), one of the most severe and fatal diseases affecting premature infants.
- Human milk oligosaccharides are one of the key nutrients that help promote brain development.As a formula-supporting ingredient, it provides the brain with an adequate supply of sialic acid.Helps support cognitive development during early and later life stages.
Incorporate our Human Milk Oligosaccharides into your products.It is not merely about adding an ingredient, but rather infusing your product formulation with the four core functions mentioned above.
