On the basis of this review , available scientific data suggest that the administration of currently evaluated probiotic- and /or prebiotic-supplemented formula to healthy infants does not raise safety concerns with regard to growth and adverse effects .
Infant formulae are increasingly supplemented with probiotics , prebiotics , or synbiotics despite uncertainties regarding their efficacy .
The present article , developed by the Committee on Nutrition of the European Society for Paediatric Gastroenterology , Hepatology , and Nutrition , systematic ally review s published evidence related to the safety and health effects of the administration of formulae supplemented with probiotics and /or prebiotics compared with unsupplemented formulae .
Effect of bifidobacterium Bb12 with or without Streptococcus thermophilus supplemented formula on nutritional status.
Acute diarrhea is a common cause of infant morbidity and mortality . Probiotic supplemented infant formula is one of the effective methods for prevention of rotavirus diarrhea . Other benefits of the probiotics supplemented formula were evaluated by monitoring the growth of the children . A double-blind , placebo-controlled trial was done in 148 children aged 6 - 36 months . They were divided into 3 groups : the Bb12 group , 51 children received infant formula with Bifidobacteria Bb12 supplement ; the Bb12+ST  group , 54 children  received infant formula with Bb12 and Streptococcus thermophilus supplement ; and the control group , 43 children received infant formula without supplement . The mean weight Z-score according to WHO reference st and ard of the Bbl2 group was -1.8 + /- 0.12 , the Bb12+ST group was -1.4 + /- 0.11 and the control group was -1.8 + /- 0.13 at entry . The mean weight Z-score of children after 6 month showed that the children in the Bbl2+ST group had the highest increase in weight which was increased from -1.4 + /- 0.11 to -0.9 + /- 0.12 compared to the Z-score of the Bb12 group which had increased from -1.8 + /- 0.12 to -1.2 + /- 0.13 and in the control group from -1.8 + /- 0.13 to -1.7 + /- 0.25 . In terms of the mean height Z-score , the Bb12 group was -2.7 + /- 0.14 to -1.7 + /- 0.16 which was higher than the Bb12+ST group ( - 2.2 + /- 0.13 to -1.7 + /- 0.13 ) but was not different from the control group . However , the mean weight/height Z-score of the Bbl2+ST group had approached the reference st and ard ( Bb12 group -0.1 + /- 0.11 to -0.1 + /- 0.13 , Bb12+ST group -0.1 + /- 0.10 to 0.3 + /- 0.17 , control group -0.4 + /- 0.12 to -0.1 + /- 0.16 ) . Data showed that children who received the probiotics supplement formula had better growth during the 6 month period
