Updated on April 18, 2011


What is resveratrol found in grape juice and what are the health benefits and potential side effects of this compound?

Resveratrol, a major chemical compound from the flavonoids class, is found as a metabolic product in some plants, but especially large quantities of it are contained in grape juice.

For decades, grape juice has been investigated as a powerful source of bioflavonoids - a type of phytochemicals that occur naturally in plants. These specific compounds are what gives the intense color of red grapes, and along with it, they contribute to the pronounced antioxidant potential of grape juice and red wine.

The Protective Features of Resveratrol

Side by side with the extremely powerful antioxidant quercetin, a special focus is given to resveratrol - which is also a powerful antioxidant.

Why is resveratrol produced in some plants at the first place?

Simply, this compound is used by the plant as a protective agent against diseases, in cases when the plant is damaged, or in order to create a UV protective layer in the grapes skin. This protective function of resveratrol seems to be beneficial also when it comes to human health, as some recent medical research studies have confirmed. While this compound is absorbed quite easily in our organism, its biological availability is relatively low, as resveratrol is quickly extracted from our body.

Healthy Juices as Source of Resveratrol

Apart from grape juice, resveratrol was discovered in blueberries, cranberries and peanuts. Red grapes contain up to 7 mg, red grape juice up to 8 mg, and some red wines, depending on the production technology and other factors, can have from 5 to 20 mg/l.

The quantity of fruits and juices you can consume in order to absorb the potential health benefit of resveratrol is not limited. When it comes to red wine, the recommended daily dosage is no larger than one cup or 2 dl. There should be a pause of 2 day after every week to prevent the possible alcohol addiction.
