Grape seed extract lowered the blood pressure of patients who participated in a recent University of California – Davis study of the benefits of the supplement on people with high blood pressure. Conducted by UC Davis cardiovascular researchers, the study is the first human clinical trial to assess the effect of grape seed extract on people with metabolic syndrome, a combination of risk factors (high blood pressure, excess abdominal body weight, high blood cholesterol fats, high blood sugar) that increases the risk for heart disease. The one-month study involved 24 male and female patients diagnosed with metabolic syndrome. The patients were divided into three groups of eight. The first group received a placebo, while the second and third groups received 150 milligrams and 300 milligrams, respectively, of a new grape seed extract. All participants’ blood pressure was automatically measured and recorded for 12 hours after ingestion. The average drop in systolic pressure was 12 millimeters and the average drop in diastolic pressure was eight millimeters. The UC Davis research team is currently embarking on a second placebo-controlled human clinical study of grape seed extract, examining its benefits for pre-hypertension patients.
