Probiotics and prebiotics support infant health by establishing a healthy gut microbiota, which supports the immune system and intestinal health. C-section babies are deprived of contact with beneficial maternal microbiota. Research shows probiotic supplementation with Lactobacillus reuteri reduced infant crying, regurgitation, and improved stool patterns. A clinical trial also found probiotic supplementation reduced eczema rates in infants by 40%. Prebiotics in breast milk selectively stimulate beneficial gut bacteria. The document concludes that a healthy microbiota benefits infants and research supports probiotic and prebiotic supplementation.
