The purpose of this study is to determine if a supplement called Provex CV can reduce blood pressure and other risk factors for heart disease. Heart disease is the leading cause of death in this country and it is important to identify dietary factors, including supplements, that can reduce heart disease risk factors. The supplement to be tested in this study is made of a combination of natural compounds found in plants such as grapeseed extract, green tea, and quercetin. Each compound individually has been shown to improve blood pressure or reduce inflammation. We hypothesize that Provex CV will reduce blood pressure and levels of inflammatory cytokines hypertensive patients with symptoms of metabolic syndrome. This investigational trial of Provex CV has been approved by the United States Food and Drug Administration.

Inclusion Criteria:

• Males (18 - 65) and postmenopausal females (up to age 65) with metabolic syndrome who have stage 1 hypertension.
