Grape seed extract supplements appear to lower blood pressure in people with metabolic syndrome. These findings were presented at the American Chemical Society Meeting and Exposition in Atlanta.
The 1-month study involved 24 patients diagnosed with metabolic syndrome. The patients were divided into 3 groups of 8. 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.”
Participants in the 2 groups receiving grape seed extract experienced an equal degree of reduced blood pressure. The average drop in systolic pressure was 12 millimeters. The average drop in diastolic pressure was 8 millimeters,” said the study’s lead researcher, C. Tissa Kappagoda.
Kappagoda adds that the group taking 300 milligrams of grape seed extract also had reduced serum oxidized LDL cholesterol levels.
