Differential Absorption Kinetics of Grape Seed Extract Polyphenols
Sponsor: Clinical Nutrition Research Center, Illinois Institute of Technology
Summary
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.
