(Deborah Mitchell, www.examhealth.com) Grape seed extract has been praised for a number of health benefits, including the ability to lower blood pressure in people at risk of hypertension. Along with a blood pressure benefit, here are 5 more reasons to take grape seed extract, including information from new research and some previous recent studies as well.
What could grape seed extract do for you?
Grape seeds are an excellent source of various nutrients, including vitamin E, linoleic acid, flavonoids, and oligomeric proanthocyanidin complexes (OPCs), which are a type of antioxidant. These nutrients are found in higher concentrations in grape seeds than in the skin or pulp.
Grape seed extract and blood pressure. In a University of California, Davis, study, investigators conducted a double-blind, placebo-controlled, randomized study to see if grape seed extract could lower blood pressure in people at risk for hypertension. Participants received either 300 mg per day of grape seed extract or a placebo for 8 weeks.
At the end of the trial, the average decline in systolic and diastolic blood pressures in the grape seed extract group were 8 mmHg and 5 mmHg, respectively, but there was no change in the placebo group. The authors concluded that “these findings suggest that GSE could be used as a nutraceutical in a lifestyle modification program for patients with pre-hypertension.”
Grape seed extract, obesity, and kidney function. Obesity is both a serious health problem and one that contributes to a number of life-threatening diseases as well. That’s one reason why researchers were interested in the impact of grape seed extract on kidney function. A new study appearing in Applied Physiology, Nutrition, and Metabolism explains that grape seed and skin extract successfully eliminated nearly all fat-induced kidney problems in rats fed a high-fat diet (HFD). In fact, the authors noted that “the most important result drawn from the current study is the powerful ability of GSSE [grape seed & skin extract] to alleviate HFD-induced oxidative triglyceride deposition, copper depletion, and ultimately kidney dysfunction.”
