The Best Source of Resveratrol
Written by Eli Ben-yehudaOn January 4, 2019
Last week I discussed how resveratrol helped lower your high blood pressure. Resveratrol is believed to be one of the most potent polyphenols and strongest protectors against symptoms associated with aging and free radical damage. This week Dr. Michael Greger discusses the best sources of resveratrol for your diet.
If you’ve heard that red wine can help lower cholesterol, chances are you’ve heard of resveratrol — the much-hyped plant compound found in red wine.
But beyond being a healthful part of red wine and other foods, resveratrol has health-boosting potential in its own right.
In fact, resveratrol supplements have been linked to many exciting health benefits, including protecting brain function and lowering blood pressure.
This article explains what you need to know about resveratrol, including seven of its main potential health benefits.
What Is Resveratrol?
Resveratrol is a plant compound that acts like an antioxidant. The top food sources include red wine, grapes, some berries and peanuts (5Trusted Source, 6Trusted Source).
This compound tends to be concentrated mostly in the skins and seeds of grapes and berries. These parts of the grape are included in the fermentation of red wine, hence its particularly high concentration of resveratrol.
However, much of the research on resveratrol has been done in animals and test tubes using high amounts of the compound. Of the limited research in humans, most has focused on supplemental forms of the compound, in concentrations higher than those you could get through food.
Resveratrol Supplements May Help Lower Blood Pressure
Because of its antioxidant properties, resveratrol could be a promising supplement for lowering blood pressure.
A 2015 review concluded that high doses may help reduce the pressure exerted on artery walls when the heart beats.
That type of pressure is called systolic blood pressure, and appears as the upper number in blood pressure readings. Systolic blood pressure typically goes up with age, as arteries stiffen. When high, it’s a risk factor for heart disease.
Resveratrol may accomplish this blood-pressure-lowering effect by helping to produce more nitric oxide, which causes blood vessels to relax.
However, the authors of that study say more research is needed before specific recommendations can be made about the best dose of resveratrol to maximize blood pressure benefits.
