Human milk oligosaccharides (HMOs) are complex glycoproteins that are especially important for the growth and development of a baby's immune system. Oligosaccharides can also play an important role in the mother-child bond. In this article, we will explore the meaning of human milk oligosaccharides and their importance to human health.

What are Human Milk Oligosaccharides?

Human milk oligosaccharides (HMOs) are complex carbohydrate molecules that are unique to human milk and play an important role in the health of infants. HMOs are composed of a small number of sugar molecules linked together by glycosidic bonds.

They can be divided into two main groups based on the way they are linked together:

●      Prebiotic: It promotes the growth of beneficial bacteria in the intestines

●      Probiotic: It helps to protect against infection

Human milk oligosaccharides have been shown to provide infants with benefits such as improved immunity, regulation of blood sugar levels, and prevention of allergies. In fact, some researchers believe that HMOs may be responsible for some of the increased rates of immunity seen in breastfed infants compared to formula-fed infants. Some studies have also shown that HMOs can improve cognitive function in young children.

Despite their many benefits, HMOs are poorly understood by scientists and are currently not considered to be an essential nutrient by the Food and Nutrition Board of the U.S. Department of Agriculture (FNB). However, recent studies suggest that toddlers who consume high levels of pre

How Do They Affect Baby’s Development?

Human milk oligosaccharides (HMOs) are complex carbohydrates that are found in high concentrations in breast milk. They have been shown to have positive effects on a baby's development, including helping to regulate the immune system and aiding in the absorption of nutrients. HMOs can also help to protect against allergies and asthma, and may play a role in promoting a healthy weight during childhood.

Are They Safe to Include in Breastfeeding Supplements?

Human milk oligosaccharides are fragments of sugar molecules that are abundant in breast milk. While scientists are still learning a great deal about these molecules, many people believe that including them in breastfeeding supplements may provide some health benefits for infants. Some research suggests that oligosaccharides may help improve gastrointestinal health, boost immunity, and support infant brain development. However, more research is needed to determine the true benefits of including these molecules in breastfeeding supplements.

Do They Offer Any Health Benefits for Adults?

Yes, human milk oligosaccharides (HMOs) do offer some health benefits for adults. HMOs are a type of prebiotic fiber that work to promote the growth of healthy bacteria in the gut. In addition, HMOs have been shown to promote weight loss and improve bowel function.

Are There Any Side Effects to Taking HMOs?

There are no known side effects associated with taking HMOs.


Oligosaccharides are complex carbohydrates that are found abundantly in human milk. These glycans help to protect the infant’s gut bacteria and may play a role in immune development. Human milk oligosaccharides are also thought to be beneficial for the growth of the child’s brain and nervous system. As we learn more about their benefits, it is clear that human milk oligosaccharides offer a great deal of potential for both mother and baby.
