Official title
Differential Absorption Kinetics of Grape Seed Extract Polyphenols: A Pilot Study
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Grape seed extracts (GSEs) contain (poly)phenols that vary in their degree of polymerization, which may lead to differences in absorption, metabolism, and biological efficacy. This pilot study will evaluate how GSEs with varying degrees of polymerization are absorbed, cleared, and metabolized in healthy adults. Two separate pilot studies will be conducted. Study 1 will evaluate MN-BP compared to another commercially available GSE. Study 2 will evaluate four next-generation (Gen 2) GSE preparations enriched in monomers, oligomers, polymers, or a mixture. Blood and urine samples will be collected at multiple time points following GSE consumption to assess bioavailability and metabolic profiles of the different GSE preparations.
