Prebiotics in infant formula

Prebiotic oligosaccharides are a major component of human breast milk (1) and have been reported to affect the growth of gastrointestinal microbiota, which can have benefits for the infant’s health. The bacterial profiles of breast-fed babies are known to differ from those of babies fed with standard formulas (2), so as a result, research has investigated the effects of supplementing formulas with different combinations of galacto-oligosaccharides (GOS), fructo-oligosaccharides (FOS) and polydextrose (PDX), to try to emulate the gold standard of breast milk. Researchers in Belgium performed a review of the latest scientific research to highlight the findings related to supplementing infant formulas. 

Effects on gastrointestinal microbiota

Formula with added prebiotics have a greater chance of affecting gut microbes when their administration begins earlier in infancy (3). There is also evidence to suggest that prebiotics can reduce adverse effects of antibiotics on the gastrointestinal microbiota (4). With respect to pre-term babies, formula supplemented with FOS, specifically, can be beneficial for gut microbiota (5). Different studies have investigated various concentrations of prebiotics in formulas and report similar stimulation of intestinal bifido and lacto to breast-fed infants (6-8).

Effects on faecal pH and metabolic activity

The pH levels in the gut effect the bacteria that can grow there, with lower pH values decreasing the amount of pathogenic bacteria (9). Supplementary prebiotics have been reported to decrease intestinal pH levels (19), reduce pH levels lower compared to standard formula (10) and even bring pH levels in-line with those observed in breast-fed infants (8). Metabolic activity in the gut of infants feed with GOS/FOS supplemented formula has been shown to be comparable to that of babies fed with breast milk (11, 12).

Effects on immunity

There is evidence to suggest a potential association between prebiotics and immune system development (13) but other research has found no significant effect (14). One study found prebiotics affected intestinal microbiota after the study intervention, which suggested a modulating effect on the immune system (15). While further investigation is warranted, it is likely that prebiotic oligosaccharides are likely to enhance the immune system.

Effects on stool consistency and frequency

Prebiotics added to formula can bring the frequency of bowel movements in-line with that of breast-fed infants (6, 7, 16). Different supplement mixtures have been shown to soften the consistency of stools (17, 18), bringing it closer to that of breast-fed babies (19), without increasing fussiness or gassiness (18).

Other areas of study

Prebiotic supplements in infant formulas are unlikely to have an effect on growth (16), while the influences on general health (20), infection reduction (8, 21) and atopic dermatitis (22, 23) remain unclear and warrant further examination.
