Resveratrol, an antioxidant compound found in red wine, is being talked about everywhere for its numerous health benefits. Multiple news reports have highlighted this new ‘wonder-supplement’ which is reported to have anti-aging properties, to improve heart health, to act as a powerful antioxidant and much more. Scientists around the world are finding new positive benefits of the supplement everyday – but what about the potential side effects of resveratrol?
Resveratrol is found in grapes which is why so much attention has been paid to the health benefits that go along with drinking red wine. However, the dosage in a glass of red wine is relatively small. The studies that are being done with this supplement are using much higher concentrations than you could get from a glass of wine.
In fact, one scientist said that to get the same benefits that were shown in his study you would need to drink 1000 bottles of wine a day! Obviously that isn’t practical. In answer to this, manufacturers have developed resveratrol supplements that allow you to take higher doses of the antioxidant without having to overdo it on wine.
Since the research being done on it is relatively new, the long term side effects of using resveratrol in humans still is not known. To date all of the results of the studies done with it are positive. However, there are a few things you should keep in mind.
Drug Interactions
One of the most important things before you start taking any supplement is to talk to your doctor and make sure that it won’t interfere with any of the prescription medication that you are currently taking. For instance, resveratrol acts as a blood thinner so if you are already on a blood thinner it could thin your blood too much. Play it safe and check with your doctor first since he knows your medical history and pre-existing conditions.
Side Effects from Mega Doses
Studies done with volunteers who were taking large doses of resveratrol (500-1000 mg) had mild but reversible side effects including over thinning of the blood, diarrhea, headaches, anxiety and abnormal blood tests. To avoid these side effects you should start with a lower dose and work your way up to higher doses.
Estrogenic Activity
Resveratrol has mild estrogenic activity which hasn’t been fully studied in humans so it should be avoided if you have an estrogen-sensitive condition. Again, talk to your doctor to make sure that it is safe for you to take.
Pregnant Women & Children
Resveratrol should not be taken by women who are pregnant, lactating or trying to become pregnant. It also should not be taken by children.
Having said all that, resveratrol has been on the market in supplement form for many years and no serious side effects have been reported. At the same time, the positive benefits of this supplement are being talked about everywhere.
