Researchers at the University of California Davis, Department of Internal Medicine demonstrated that doses of 150 mg and 300 mg per day of grape seed extract1 significantly lowered blood pressure in patients with metabolic syndrome.

Earlier grape seed extract research has shown that this natural extract can activate the production of friendly nitric oxide (eNOS) by turning on the enzyme (nitric oxide synthase) that helps to make it. This causes a relaxing effect in the arteries, helping blood flow more easily. Researchers tested 27 adults with metabolic syndrome over a four week period. Both 150 mg and 300 mg grape seed extract doses were equally effective in lowering blood pressure; systolic was lowered 11-12 points, diastolic was lowered 7-8 points. Additionally, the 300 mg dose of grape seed extract reduced the amount of damaged LDL cholesterol that may have otherwise formed plaque in the arteries.

Metabolic syndrome is a difficult health issue that tends to progress in the wrong direction over time. Any natural substance that supports healthy function with no adverse side effects is a common sense approach to help deal with it.
