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 .
A Randomized Formula Controlled Trial of Bifidobacterium lactis and Streptococcus thermophilus for Prevention of Antibiotic-Associated Diarrhea in Infants
Goals : This clinical trial was carried out to determine whether oral treatment with a commercial probiotic formula containing Bifidobacterium lactis and Streptococcus thermophilus would reduce the frequency of  antibiotic-associated diarrhea ( AAD ) in infants . Study : In this double-bind formula controlled study , 80 infants , 6 to 36 months of age , were r and omly assigned to receive a commercial formula containing 107 viable cells of B. lactis and 106viable cells of S. thermophilus at the initiation of antibiotics for a duration of 15 days . The infants were assessed daily for formula intake , stool frequency , and stool consistency for a total duration of 30 days . Seventy-seven infants received  nonsupplemented formula for the entire duration . Results : There was a significant difference in the incidence of AAD in the children receiving probiotic-supplemented formula ( 16 % ) than nonsupplemented formula ( 31 % ) . Conclusions : The present study shows that prevention against AAD in infants was obtained by oral treatment with daily dose of B. lactis and S. thermophilus
