2'-Fucosyllactose supplementation results in a transient improvement in gut microbial resilience after vancomycin use in adults with overweight or obesity: a randomized, double-blind, placebo-controlled intervention.

ABSTRACT: Antibiotic-induced perturbations of the gut microbiome can be long-lasting and potentially affect host metabolic health. Strategies supporting microbial resilience are needed to mitigate the negative impact of antibiotics. We investigated the potential of 2'-fucosyllactose (2'-FL) supplementation after vancomycin use in a double-blind placebo-controlled randomized intervention among adults with overweight/obesity. Participants received oral vancomycin for seven days followed by 2'-FL or placebo for eight weeks. At baseline, after vancomycin use and after supplementation, glucose tolerance, insulin sensitivity, plasma lipids, glucagon-like peptide 1, inflammatory cytokines, fecal short-chain fatty acids (SCFAs) and branched-chain fatty acids were analyzed.
