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 .

Prebiotics increased stool frequency but had no impact on stool consistency , the incidence of colic , spitting up / regurgitation , crying , restlessness or vomiting .

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 .
Effects of probiotic or prebiotic supplemented milk formulas on fecal microbiota composition of infants.
The aim of the study was to evaluate whether supplementation of milk-formulas with prebiotic fructo-oligosaccharides or a probiotic , Lactobacillus johnsonii La1 ( La1 ) , could modulate the composition of the fecal microbiota of formula-fed infants , compared to breastfed ( BF ) infants . Ninety infants close to 4 months of age were r and omized into one of three groups to be blindly assigned to receive for 13 weeks : a ) an infant formula ( Control ) , b ) the same formula with fructo-oligosaccharides ( Prebio ) , or c ) with La1 ( Probio ) . At the end of this period , all infants received the control formula for 2 additional weeks . Twenty-six infants , breastfed throughout the study , were recruited to form group BF . Fecal sample s were obtained upon enrolment and after 7 and 15 weeks . Bacterial population s were assessed with classical culture techniques and fluorescent in situ hybridisation ( FISH ) . Seventy-six infants completed the study . On enrolment , higher counts of Bifidobacterium and Lactobacillus and lower counts of enterobacteria were observed in BF compared to the formula-fed infants ; these differences tended to disappear at weeks 7 and 15 . No major differences for Clostridium , Bacteroides or Enterococcus were observed between the groups or along the follow up . Probio increased fecal Lactobacillus counts ( p<0.001 ) ; 88 % of the infants in this group excreted live La1 in their stools at week 7 but only 17 % at week 15 . Increased Bifidobacterium counts were observed at week 7 in the 3 formula groups , similar to BF infants . These results confirm the presence of higher counts of bifidobacteria and lactobacilli in the microbiota of BF infants compared to formula-fed infants before dietary diversification , and that La1 survives in the infant digestive tract
