Insights
Infant formula supplemented with synbiotics, containing prebiotics (fructooligosaccharides and galactooligosaccharides) and Lactobacillus paracasei, demonstrated safety for infant growth. Synbiotics showed a potential, though uncertain, reduction in respiratory infections compared to prebiotics alone.
Area of Science:
- Pediatric Nutrition
- Microbiome Research
- Infant Health
Background:
- Growth is a key indicator for infant formula (IF) safety.
- Investigated IF with prebiotics (FOS/GOS) versus synbiotics (FOS/GOS + L. paracasei F19).
Purpose of the Study:
- To assess the impact of synbiotic-supplemented IF on healthy infant growth.
- To compare growth outcomes between prebiotic- and synbiotic-supplemented IF.
Main Methods:
- 182 healthy, full-term infants were randomized at 28 days of age.
- Infants received either prebiotic- or synbiotic-supplemented IF until 6 months of age.
- Growth and safety parameters were monitored through 12 months.
Main Results:
- No significant differences in anthropometric parameters between groups up to 12 months.
- Synbiotic group showed a potential reduction in lower respiratory tract infections, but with wide confidence intervals.
- No serious adverse events were reported in either group.
Conclusions:
- Synbiotic-supplemented IF is safe for infant growth, with no significant differences compared to prebiotic-supplemented IF.
- Further research is needed to confirm the effect of synbiotics on lower respiratory tract infections.
Background:
Growth is an essential outcome measure for evaluating the safety of infant formulas (IF). We investigated the effects of consumption of IF supplemented with prebiotics (fructooligosaccharides, FOS, and galactooligosaccharides, GOS) compared with synbiotics (FOS/GOS and Lactobacillus paracasei ssp. paracasei strain F19) on the growth of healthy infants.
Methods:
182 full-term infants who were weaned completely from breast milk to IF at 28 d of age were randomly assigned to receive prebiotic- or synbiotic-supplemented, otherwise identical, IF until 6 mo of age (intervention period).
Results:
A total of 146 (80%) infants were included in the intention-to-treat analysis at 6 mo. Anthropometric parameters were similar in the two groups during the intervention and follow-up period until 12 mo of age. Compared with the prebiotic group, a significant reduction in the cumulative incidence of lower respiratory tract infections was found in the synbiotic group; however, the confidence interval of the estimate was wide, resulting in uncertainty.
Conclusion:
The lack of a significant difference between the formula-fed groups in growth, or the occurrence of serious adverse events, supports the safety of using IF supplemented with synbiotics. Further studies are needed to evaluate the effects of such formula on lower-respiratory tract infections.
