What are Human Milk Oligosaccharides? 

HMOs are a collection of carbohydrate structures and the third most abundant solid component of human milk after fats and lactose. In infants, HMOs help to develop the desired microbiota by serving as a food source for the good bacteria in the intestine. Naturally occurring in breast milk, HMOs have evolved over thousands of years, with clinical and preclinical studies now suggesting that specific HMOs and levels may provide us with unique health benefits. In particular, they may help support both immunity and a healthy gut, with a potential role in cognitive development, which may open future innovation opportunities.

Global consensus supports breastfeeding as the gold standard to give newborns the best start in life. When mothers cannot breastfeed, or choose not to breastfeed, whatever the reason may be, a safe and suitable breastmilk substitute should be available and fed to the newborn. Together, DSM and Glycom support their customers in developing innovative solutions to help set formula-fed infants on a path to a long, healthy life, which is part of DSM’s promise to help keep the world’s growing population healthy. 

We support independent science through free donations of our products. We have already donated our Human Milk Oligosaccharides to +55 research programs in more than 40 research institutions across the world. These programs have so far led to 15 publications. For a list of publications, click here


<p>HMO Research</p>

HMO Research

Emerging evidence from our preclinical research suggests that HMOs:

  • Help to increase the relative abundance of beneficial bacteria, while reducing the growth of potentially detrimental bacteria; for example Clostridium difficile and coli (1)
  • May help the intestinal bacterial composition recover after antibiotic use (1)
  • May help to increase the concentration of beneficial bacterial metabolites which are key nutritional components for intestinal barrier and immune cells, while reducing detrimental metabolites (2,3,4)
  • May support the immune response to rota-virus via modulation of the intestinal microbiota and immune cell populations (5,6)
<p>Important results for infants</p>

Important results for infants

A clinical study supplementing with the HMOs, 2’FL + LNnT has reported (7):

  • They are safe and well tolerated when supplemented in infant formula.
  • They help to support the growth of beneficial bacteria.
  • A significantly reduced incidence of lower respiratory tract infections by 43% and bronchitis by 63% during the first year of life as compared to a standard infant formula 
  • A significantly reduced use of antibiotics and fever medication as compared to a standard infant formula during the first year of life 
<p>Older children and adults </p>

Older children and adults 

Results from a clinical study using Glycom’s HMOs, 2’FL and LNnT indicate (8):

  • 2’FL and LNnT are safe and well tolerated in adults, at doses of up to 20g/day .
  • 2’FL and LNnT help support the growth of beneficial bacteria, in particular bifidobacteria.

Furthermore, we are specifically investigating the effect of our HMOs on obese children and on participants suffering from irritable bowel syndrome (IBS) in blinded and placebo-controlled clinical studies.

<p>HMO Product Portfolio</p>

HMO Product Portfolio

Next-generation HMOs are part of Glycom’s exciting innovation roadmap, with four new HMOs becoming available this year for innovation trials to further catalyze the already fast-growing HMO market. 

We currently offer HMOs from two HMO structural classes: 2'-fucosyllactose (2'FL), the most abundant fucosylated HMO in breast milk, and Lacto-N-neotetraose (LNnT), one of the most abundant neutral core HMOs in breast milk.
