Comparison of the Bioavailability of the Flavanol of Grape Extracts

Polyphenols are a group of naturally occurring compounds found in cocoa, teas, and grape seed extracts (GSE) that have been linked to various health benefits. This study will provide a greater insight into the relationship between polyphenol consumption and health, and could be used to help with the development of functional food products and novel supplements. Although the advantages of a polyphenol-rich diet are well-established, the bioavailability of GSE (a source of polyphenols) in the context of human digestion and beneficial properties are poorly understood. The investigators will conduct an open-label, randomized, 4-way crossover design with the aim to explore the bioavailability of GSE-derived flavan-3-ols from GSE and their related microbial metabolites and advance understanding of the bioactive properties of flavan-3-ols contributing to the development of more effective dietary strategies and functional food products.
