Official title
Exploratory Study to Determine the Bioavailability and Metabolism of Ellagic Acid From Pomegranate Juice vs. Pure Ellagic Acid
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this research study is to compare the extent of polyphenol absorption in the body in normal healthy male volunteers when consuming either pomegranate juice or pure ellagic acid, an ellagitannin naturally present in pomegranates. Polyphenols are naturally occurring chemicals found in plant based food that serve to reduce inflammation and damage to cells. You will be asked to avoid foods rich in polyphenols including dark chocolate and cocoa products, dried herbs, berries, coffee, tea, flaxseeds, nuts (chestnut, hazelnut), olive and artichoke. Timed urine collections will be used to measure the metabolism of polyphenols through the presence and concentration of urolithin and ellagic acid metabolites. Additionally, it has been demonstrated in animal studies that fruits and vegetables, which are high in antioxidants and fiber, lead to improvement of gut health, inflammation and glucose tolerance. However, no information is available about the effect of ellagitanins on the gut microbiome (bacteria in the intestines).
