Grape Seed Extract Shows Potential for Blood Pressure Reduction

According to a recent study, grape seed extract may have beneficial effects on blood pressure levels.

The study, published in the Journal of the American College of Nutrition, involved 36 adults with pre-hypertension, a condition that can progress to hypertension, a major risk factor for cardiovascular disease. The participants were randomly assigned to receive either a placebo or a grape seed extract supplement containing 300 mg of proanthocyanidins, a type of antioxidant found in grape seeds.

After six weeks of supplementation, the researchers found that the group taking grape seed extract had significantly lower systolic and diastolic blood pressure compared to the placebo group. Systolic blood pressure, which measures the pressure in arteries when the heart beats, decreased by an average of 5.6 mmHg in the grape seed extract group, while it increased by 1.3 mmHg in the placebo group. Diastolic blood pressure, which measures the pressure in arteries between heartbeats, decreased by an average of 2.6 mmHg in the grape seed extract group, while it increased by 1.1 mmHg in the placebo group.

The researchers also found that the grape seed extract supplement was safe and well-tolerated by the participants, with no significant adverse effects reported.

Although the study has some limitations, such as a small sample size and a short duration, it provides preliminary evidence that grape seed extract may have potential as a natural intervention for blood pressure management. Further research is needed to confirm these findings and determine the optimal dose and duration of grape seed extract supplementation for blood pressure reduction.
