Acute Effect of a Proprietary Botanical Blend Rich in Polyphenols on Flow-mediated Dilation in Healthy Subjects

Healthy Clinical Trial

Official title:
Acute Dose-response Effect of a Proprietary Botanical Blend Rich in Polyphenols on Flow-mediated Dilation in Healthy Subjects: Randomized, Cross-over, Double-blind Clinical Study

Clinical Trial Summary

It is well established that endothelial dysfunction is an early predictor of cardiovascular events in at-risk patients. Finding safe and effective product able to improve endothelial function is of public health interest. Many clinical studies have shown that monomer of flavanols from cocoa significantly improved endothelial function, in particular endothelium-dependent flow-mediated dilation (ED-FMD) after a single dose. Grape is also a main source of flavanol monomers, that's why many human studies have shown significant effects of grape-derived products on endothelial function within 2 hours following a single dose intake. The objective of this study is to assess the effect of 2 doses of a proprietary and standardised botanical blend rich in polyphenols (SBRP), on ED-FMD in fasting conditions, in comparison to a placebo, in healthy adults. This blend is made of two botanical extracts: a grape extract and a blueberry extract. In order to provide supportive evidence on the mechanisms and biological plausibility to the clinical effects of the product, appropriate biological parameters and circulating metabolites will be assayed.
