Study snapshot

DesignComparative pharmacokinetic and microbiome study
ModelHuman participants; see population
Sample20 healthy men; 10 African and 10 Chinese participants
InterventionSingle oral berberine hydrochloride 600 mg (542.8 mg active berberine), with breakfast; gut-microbiota profiling
Duration12-hour pharmacokinetic sampling
EndpointsPlasma exposure and pharmacokinetics; Drug interaction measurements; Short-term tolerability

What the study showed, in plain terms

Exposure differed between these small volunteer groups and correlated with selected gut microbial abundances.

Key findings

  • Exposure differed between these small volunteer groups and correlated with selected gut microbial abundances.

What this study can and cannot tell us

Population labels do not define an individual’s response; microbiota correlations do not independently establish causation.
