Prebiotic Oligosaccharides Enhance Iron Absorption Via Modulation of Protein Expression and Gut Microbiota in a Dose-Response Manner in Iron-Deficient Growing Rats.

For the first time, the present study provides evidence that GOS supplementation induces a dose-response effect on iron absorption and gut microbiota in the established model, suggesting a positive role of GOS in ameliorating IDA in children.
