Synbiotics failed to significantly increase growth in boys and girls .
Use of synbiotics increased stool frequency , had no impact on stool consistency , colic , spitting up / regurgitation , crying , restlessness or vomiting .
Probiotics in formula also failed to have any significant effect on growth , stool frequency or consistency .
Probiotics did not lower the incidence of diarrhoea , colic , spitting up / regurgitation , crying , restlessness or vomiting .
Prebiotics in formula did increase weight gain but had no impact on length or head circumference gain .
Prebiotics increased stool frequency but had no impact on stool consistency , the incidence of colic , spitting up / regurgitation , crying , restlessness or vomiting .
There was no impact of prebiotics on the volume of formula tolerated , infections and gastrointestinal microflora .
Authors ’ conclusions There is not enough evidence to state that supplementation of term infant formula with synbiotics , probiotics or prebiotics does result in improved growth or clinical outcomes in term infants .
There is no data available to establish if synbiotics are superior to probiotics or prebiotics
Background Synbiotics , probiotics or prebiotics are being added to infant formula to promote growth and development in infants .
Previous review s ( 2007 to 2011 ) on term infants given probiotics or prebiotics focused on prevention of allergic disease and food hypersensitivity .
This review focused on growth and clinical outcomes in term infants fed only infant formula containing synbiotics , probiotics or prebiotics .
Growth during the first 6 months of life in infants using formula enriched with Lactobacillus rhamnosus GG: double-blind, randomized trial.
BACKGROUND Probiotic bacteria have beneficial effects on the immune system and gastrointestinal tract , but the impacts of their long-term consumption on health and growth in early infancy are not well documented . The aim of this study was to evaluate the influence of Lactobacillus rhamnosus GG (LGG)-enriched formula on growth and faecal microflora during the first 6 months of life in normal healthy infants . MATERIAL S AND METHODS One hundred and twenty healthy infants ( up to 2 months ) received LGG-supplemented formula or regular formula in a double-blind , r and omized manner until the age of 6 months . Weight , length and head circumference were measured monthly and transformed into st and ard deviation scores ( SDS ) . Faecal sample s were obtained from a r and om sample of infants ( n=25 ) at entry and at the end of the study . RESULTS One hundred and five infants ( 51 in the LGG group ) completed the study . Children receiving LGG-supplemented formula grew better : their changes in their length and weight SDS ( DeltaSDS ) at the end of the study were significantly higher than those receiving regular formula ( 0.44+/- 0.37 versus 0.07+/- 0.06 , P < 0.01 and 0.44+/- 0.19 versus 0.07+/- 0.06 , P < 0.005 , respectively ) . The LGG group had a significant , higher defecation frequency 9.1+/-2.06 versus 8.0+/- 2.8 ( P<0.05 ) . More frequent colonization with lactobacilli was found in the LGG group , 91 % versus 76 % ( P<0.05 ) at the end of the study . CONCLUSIONS Infants fed with LGG-enriched formula grew better than those fed with regular formula . Further studies are necessary to clarify the mechanism of LGG in infant growth
