Exploration of Potential Biomarkers of Polyphenol Intake From a Supplement Derived From Artichoke By-products Rich in Hydroxycinnamic Acids (ARTI-UP ADME)

The bioavailability study analyzes the absorption, distribution, metabolism, and excretion (ADME) processes of the polyphenols under study (HCAs). To achieve the planned objectives, blood and urine samples will be collected before and at different time intervals following the intake of the study supplement, which will consist of capsules made from dehydrated artichoke by-products rich in HCAs. To determine the bioavailability of the active compounds, volunteers will be asked to follow a diet low in polyphenols/plant-based foods for 48 hours prior to the supplement intake and up to 48 hours after product consumption . Blood and urine samples will be collected before intake and during the following 48 hours. Subsequently, the samples will be analyzed using high-performance liquid chromatography coupled with mass spectrometry (HPLC-MS) to identify and quantify the bioactive compounds of interest and their metabolites. The results of the ADME trial will allow for the identification of plasma and urinary metabolites, the characterization of intake markers, and the determination of inter-individual differences in metabolic profiles.
