Lactobacillus rhamnosus GG

Lactobacillus rhamnosus GG (LGG) is a bacterial strain belonging to the Lactobacillus family, first isolated in 1983 by researchers Gorbach and Goldin, from whose initials it takes its name. It is one of the most extensively studied probiotic strains in the world and is naturally found in the human gut microbiota. It is distinguished by its ability to adhere to the intestinal mucosa and resist gastric acidity, allowing it to transiently colonise the digestive tract. LGG contributes to the balance of the gut microbiota and the maintenance of a diverse intestinal flora. Clinical studies have associated it with support for natural defences, digestive comfort — particularly in cases of antibiotic-associated diarrhoea — and the maintenance of intestinal barrier integrity. Supplementation with Lactobacillus rhamnosus GG is of particular interest during periods when the microbiota is under stress: antibiotic use, periods of stress, dietary imbalances or travel. Its well-documented safety profile makes it one of the reference strains in probiotic supplementation.
