RecruitingClinical trialInfluence of the Gut Microbiome on Blueberry Polyphenol MetabolitesThe objective of this study is to determine whether inter-individual differences in the gut microbiome influence exposure to blueberry polyphenol metabolites. We will use pharmacokinetics of blueberry polyphenols after an acute blueberry exposure to group individuals into "metabotypes", groups of individuals based on similarity in their metabolite profiles. We will then use multi-omic approaches to determine whether the gut microbiome predicts an individual's metabotype.
