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.

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.

Inclusion Criteria:

• Slight or type 1 hypertension with no pharmacological treatment, but with annual controls of the blood pressure

Exclusion Criteria:

• Minors (under 18 years of age)
• volunteers with high cardiovascular disease risk
• pharmacological treatment for blood pressure
• presence of any chronic disease/condition
• known allergies regarding the supplement and/or placebo
