New evidence
Maternal probiotic supplementation tied to a 48% lower risk of infant eczema in an umbrella review — but the overall evidence base is too weak to call it a win yet.
This is the first broad synthesis to link a specific probiotic (Lactobacillus lactis LI-23) to reduced eczema in babies, but because the underlying studies were weak and the review itself is early, the finding is intriguing rather than actionable.
An umbrella review of multiple studies found that mothers who took probiotics during pregnancy had babies with roughly half the risk of eczema in the first two years of life. However, the same review flagged that the overall quality of the evidence is low, meaning we can't yet be confident the effect is real or generalizable.
Where this fits in the evidence
This is among the first studies we've indexed on Lactobacillus lactis LI-23 for Reduced Offspring Eczema Risk — treat it as an early signal until more research accumulates.
