Surprising
A probiotic cut eczema severity by nearly 4 SCORAD points in kids — but the same analysis found other strains did nothing.
This is an early, promising signal for B. breve Bb-18 specifically, but the overall evidence is still thin — the umbrella analysis pooled just 150 children, and other probiotics tested in the same review failed to budge eczema severity at all.
A new umbrella meta-analysis of 150 children found that certain probiotics, including Bifidobacterium breve Bb-18, modestly reduced eczema severity — measured by a drop of about 4 points on the SCORAD scale. But the benefit wasn't universal: the same review found that other probiotic strains had no significant effect on eczema severity, and the overall evidence for this specific bacterium is still very early.
Where this fits in the evidence
This is among the first studies we've indexed on Bifidobacterium breve Bb-18 for Reduced Atopic Dermatitis Severity — treat it as an early signal until more research accumulates.
