Big effect
Probiotics cut children's eczema severity by a moderate-to-large margin in a meta-analysis — but left their allergy-related IgE levels unchanged.
This analysis of six studies suggests Lactobacillus acidophilus L-92 may be a helpful add-on for pediatric atopic dermatitis, but the benefit appears limited to symptom relief, not underlying immune markers, and the overall evidence is only moderate.
In children with atopic dermatitis, probiotic treatment was linked to a moderate-to-large reduction in disease severity, as measured by the SCORAD index. However, the same analysis found no significant change in IgE levels, meaning the probiotics improved visible symptoms without altering a key allergy-related blood marker. The finding is based on six studies with consistent beneficial results, but the exact dose wasn't specified and more research is needed to confirm which strains work best.
Where this fits in the evidence
Pillser has synthesized 6 studies on Lactobacillus acidophilus L-92 for Reduced Atopic Dermatitis Severity — overall evidence strength: Moderate.
Across 6 studies, all reported beneficial effects of Lactobacillus acidophilus L-92 on reducing atopic dermatitis severity, with 4 showing statistically significant findings. The predominant effect size is moderate, and evidence is strongest in children and adult clinical populations. Dose information is limited, with only one study specifying a heat-killed and dried L-92 daily regimen.
