NCT02063477

Brief Summary

The objective of the study is to evaluate the effect of consumption of a food supplement rich in procyanidins extracted from the bark of French pine, Oligopin®, on blood pressure of people with mild / moderate degree of hypertension. Furthermore, the effect Oligopin® consumption on markers involved in the development of hypertension, and endothelial function in key enzymes that regulate blood pressure, inflammation and oxidation are considered. Also, try to advance the understanding of the molecular mechanisms that regulate blood pressure.
