The Effect of Galactooligosaccharides (GOS) on the Gut Microbiota of Lactose Intolerance Individuals

Galactooligosaccharides (GOSs) are a group of nondigestible oligosaccharides consisting of galactose units linked via glycosidic bonds to galactose, terminal glucose, or sucrose. The linkages are not digested by human and animal pancreatic or intestinal enzymes. Some recent papers reported that daily supplementation with prebiotic GOS to lactose-intolerant individuals altered the gut microbiome and decreased lactose intolerance (LI) symptoms.
