Lactobacillus Rhamnosus Gg for Eczema Relief

Research suggests that Lactobacillus rhamnosus GG may offer some benefit for eczema relief in children with cow's milk allergy, particularly in helping them develop tolerance to the allergen over time. The available evidence comes from a 2018 meta-analysis that pooled data from nine randomized controlled trials involving 895 children, with subgroup analyses pointing to LGG as a potentially effective strain, especially when used for at least two years in infants with suspected cow's milk allergy. However, the authors themselves rated their confidence in these findings as only moderate to low, citing small sample sizes, imprecise results, and concerns about bias in the underlying studies. Overall, while the direction of evidence is cautiously supportive, the limitations of the research mean these findings should be interpreted carefully, and the picture remains incomplete.
