Prebiotic oligosaccharides: supporting gut health in preterm infants – a guide for healthcare professionals

In this guide for healthcare professionals, we take a look at the importance of supporting the gut microbiota and the role that prebiotics can play in creating positive health outcomes in preterm infants.

Every year 15 million infants around the world are born too early and before completion of the 37th week of pregnancy, and preterm birth is the number one cause of child mortality around the world¹.

Infants who are born prematurely often face multiple health concerns, including feed intolerance, poor gut barrier function and increased risk of infection²⁻⁴. The gut microbiota in these infants is considered to be important for protection against harmful microorganisms and for the maturation of the immune system⁵. Increasing evidence suggests that promoting a healthy microbiota is key to supporting the best possible outcomes in preterm infants³.

Good nutritional support of preterm infants has been shown to improve neonatal growth and developmental outcomes, including brain development, to support optimal long term health⁶,⁷.

The benefits of breast milk on the microbiota

Breast milk is universally recognised as promoting the best health outcomes in both preterm and term infants by providing a unique combination of nutrients and immune-protective factors⁸,⁹. A key benefit of breast milk is the promotion of a healthy gut microbiota, which is in part attributed to the presence of prebiotic oligosaccharides (OS) supporting gut intestinal flora development (figure 1)⁴,¹⁰.

Figure 1:

Adapted from: Harmsen, et al. 2000 Figure 1 – The microbiota of breastfed newborn infants is dominated by beneficial bifidobacteria (up to 90%) and has lower levels of harmful bacteria (such as E. coli and Bacteroides) compared to infants fed a formula without prebiotics during the first 20 days of life¹⁰.

Prebiotic oligosaccharides positively influence the gut microbiota

If breast milk is not available or available in sufficient amounts for a preterm infant, a specific preterm formula is recommended¹¹. Several clinical studies have proven that a formula containing prebiotic OS (compared to a formula without prebiotic OS) helps to support the preterm gut microbiota in a number of different ways:

  • Increasing the number of bifidobacteria in the gut (Figure 2)¹².
  • Promoting stool frequency patterns and consistency similar to breast milk fed infants¹²,¹³.
  • Reducing numbers of potentially pathogenic bacteria in the gut¹⁴.
  • Potentially improving enteral tolerance in very preterm infants¹³,¹⁵.

Figure 2:

Adapted from: Boehm, et al. 2002 Figure 2 – Preterm infants receiving a preterm formula with prebiotic OS for 28 days had significantly higher levels of bifidobacteria in the gut, compared to the group receiving a formula without prebiotic OS (p=0.0008).¹²

Our healthcare professional helpline

Our free healthcare professional helpline is open from 8am to 8pm, Monday to Friday. Just phone 0800 996 1234 for expert advice on infant feeding and nutrition, including common infant feeding problems such as cows’ milk allergy, colic, constipation and reflux.


IMPORTANT NOTICE: Breastfeeding is best for babies. Infant formula is suitable from birth when babies are not breastfed. Follow-on milk is only for babies over 6 months, as part of a mixed diet and should not be used as a breastmilk substitute before 6 months. We advise that all formula milks including the decision to start weaning should be made on the advice of a doctor, midwife, health visitor, public health nurse, dietitian, pharmacist or other professional responsible for maternal and child care. Foods for special medical purposes should only be used under medical supervision. May be suitable for use as the sole source of nutrition for infants from birth, and/or as part of a balanced diet from 6–12 months. Refer to label for details.
