Summary
This comprehensive meta-analysis of the existing studies leads to a suggestion, by no means statistically significant, that probiotics might reduce the incidence of atopic disease when administered to infants at high risk.
Analysis
However, the data is not powerful enough to make recommendations for routine use. More studies are needed, especially of a condition with so many variables and variations. Having said that, probiotics are widely used, and likely have no negative effects, so individuals might choose to utilize them in the absence of convincing data.
