About this study

Official title: Effect of the Combination of Polyphenols Derived From the Hibiscus Sabdariffa and Lippia Citriodora on Slightly Hypertensive or Type 1 Hypertensive Volunteers

Determine if a double-blind, randomized, placebo-controlled clinical intervention, based on a dietetic intervention and physical exercise, supplemented with a polyphenolic extract, decreases blood pressure in hypertensive volunteers.

Read the detailed description

Slightly hypertensive individuals, before diagnosed with type 1 hypertension, are generally monitored by their physician and given dietetic and physical activity guidelines. The objective of this intervention is to prevent onset of a hypertensive pathologic condition. However, in many cases, this intervention is unsuccessful, and therefore the patient must follow-up with anti-hypertensive drugs.

Here, in the current study, the objective is to include a nutritional supplement in the intervention in order to increase the probability of success of the diet/exercise intervention. Previous studies with the supplement Metabolaid has shown the product to significantly decrease the blood pressure of slightly hypertensive individuals. It is estimated, based on the results of previous clinical studies, that the polyphenolic content of the nutritional supplement will reduce at least an additional 10% of the blood pressure of the patients undergoing a diet and exercise intervention.
