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 .
Assessment of the safety, tolerance, and protective effect against diarrhea of infant formulas containing mixtures of probiotics or probiotics and prebiotics in a randomized controlled trial.
BACKGROUND Probiotics and prebiotics are considered to be beneficial to the gastrointestinal health of infants . OBJECTIVE The objective was to evaluate infant formulas containing probiotics and synbiotics ( combinations of probiotics and prebiotics ) for safety and tolerance . DESIGN In a prospect i ve , controlled , double-blind , r and omized trial , healthy full-term infants were exclusively fed a control formula or study formulas containing Bifidobacterium longum BL999 ( BL999 ) + Lactobacillus rhamnosus LPR ( LPR ) , BL999 + LPR + 4 g/L of 90 % galactooligosaccharide/10 % short-chain fructooligosaccharide ( GOS/SCFOS ) , or BL999 + Lactobacillus paracasei ST11 ( ST11 ) + 4 g/L GOS/SCFOS from < or = 2 to 16 wk of age ( treatment period ) . Safety and tolerance were assessed based on weight gain during the treatment period ( primary outcome ) as well as recumbent length , head circumference , digestive tolerance , and adverse events ( secondary outcomes ) , which were evaluated at 2 , 4 , 8 , 12 , 16 , and 52 wk of age . RESULTS Two hundred eighty-four infants were enrolled . During the treatment period , difference in mean weight gain between control and study formula groups in both the intention-to-treat and per- protocol population s were within the predefined equivalence boundaries of + /-3.9 g/d , indicating equivalent weight gain . Secondary outcomes did not show significant differences between groups during the treatment period . CONCLUSION Infants fed formulas containing probiotics or synbiotics show a similar rate in weight gain compared with those fed a control formula and tolerate these formulas well
