AVELOR SUMMARY

GOS are prebiotic oligosaccharides found in breast milk and synthesized from lactose. They selectively feed Bifidobacterium (even more selectively than FOS/inulin). GOS + FOS combination is used in infant formula to mimic breast milk prebiotics. In adults: 2.5-10g/day increases Bifidobacterium, improves calcium absorption by 20%, and reduces traveler's diarrhea by 40%. Better tolerated than inulin (less gas). Vivinal® GOS and Bimuno® are branded forms. --- *Reviewed by the Dose AI Research Team and Clinical Advisory Board* *Last updated: 2026-04-06*
