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 .
Low level of galacto-oligosaccharide in infant formula stimulates growth of intestinal Bifidobacteria and Lactobacilli.
AIM To investigate the effect of a new infant formula supplemented with a low level ( 0.24 g/100 mL ) of galacto-oligosaccharide ( GOS ) on intestinal micro-flora ( Bifidobacteria , Lactobacilli and E. coli ) and fermentation characteristics in term infants , compared with human milk and a st and ard infant formula without GOS . METHODS Term infants ( n = 371 ) were approached in this study in three hospitals of China . All infants started breast-feeding . Those who changed to formula-feeding within 4 wk after birth were r and omly assigned to one of the two formula groups . Growth and stool characteristics , and side effects that occurred in recruited infants were recorded in a 3-mo follow-up period . Fecal sample s were collected from a sub population of recruited infants for analysis of intestinal bacteria ( culture technique ) , acetic acid ( gas chromatography ) and pH ( indicator strip ) . RESULTS After 3 mo , the intestinal Bifidobacteria , Lactobacilli , acetic acid and stool frequency were significantly increased , and fecal pH was decreased in infants fed with the GOS-formula or human milk , compared with those fed with the formula without GOS . No significant differences were observed between the GOS formula and human milk groups . Supplementation with GOS did not influence the incidence of crying , regurgitation and vomiting . CONCLUSION A low level of GOS ( 0.24 g/100 mL ) in infant formula can improve stool frequency , decrease fecal pH , and stimulate intestinal Bifidobacteria and Lactobacilli as in those fed with human milk
