NCT01688154

Brief Summary

Grape seed proanthocyanidins have been reported to possess a hypotriglyceridemic effect after an acute or chronic consumption in rodents. In this study, we aimed to investigate the effects of an acute consumption of proanthocyanidins before a breakfast meal in humans. Moreover, the mechanisms implicated in the reduction of plasma triglycerides levels by grape seed proanthocyanidins in humans should be elucidated as well as its activity on vascular function.
