Across 11 review studies, all reported beneficial moderate-sized effects of Lactobacillus acidophilus L-92 on reducing allergic symptoms (including pollen allergy, atopic dermatitis, and allergic rhinitis). No specific dose, form, or population data were available, and none of the studies reported statistical significance. The evidence is based entirely on reviews, with no original clinical trials in the database.
Caveats: Available evidence is overwhelmingly positive — clinical literature in this area is subject to publication bias (null-result studies are less likely to be published or indexed). Many of the included studies did not reach statistical significance — effect may be smaller than the predominant direction suggests. All included studies are review articles; no original clinical trial data were available in the database, limiting the strength of conclusions.
