Also known as: L. rhamnosus, LGG, Lactobacillus rhamnosus GG
Lactobacillus rhamnosus GG is one of the most clinically studied probiotic strains worldwide. It is particularly effective in preventing and treating diarrhea and supporting immune resilience in both adults and children.
Lactobacillus rhamnosus, particularly the GG strain (LGG), is a Gram-positive bacterium with strong adhesion to intestinal epithelial cells, allowing it to persist in the gut and exert sustained beneficial effects. Hundreds of clinical studies support its role in reducing the duration of infectious diarrhea, preventing antibiotic-associated diarrhea, and decreasing the risk of traveler's diarrhea. LGG has also demonstrated immunomodulatory effects, including enhanced mucosal IgA responses, and has been studied for its potential to reduce the incidence of respiratory infections and eczema in children. It is considered safe for most populations and is widely available in both supplement and food form.
LGG has been shown in multiple meta-analyses to reduce the duration of acute diarrhea by approximately 1 day and to lower the risk of antibiotic-associated diarrhea.
Studies indicate LGG supplementation may reduce the incidence of upper respiratory tract infections and the need for antibiotics, particularly in children.
With meals or on an empty stomach
The GG strain has been studied at doses up to 40 billion CFU/day without adverse effects.
