Resveratrol has been in our lives for a long time because you can find it in plants and fruits. On the other hand resveratrol supplements have been on the market for only a few years. The problem here is, there are no long term clinical studies on resveratrol side effects on humans. So, we right now we have no study on long term resveratrol side effects for the supplements.
The good news is that humans have a long history of drinking wine, eating grapes and peanuts. These all contain resveratrol naturally and in general without any serious side effects from resveratrol. Scientist have done animal toxicity tests on resveratrol and found it to be safe, even at a very high dosage.
You do need to use some caution when taking resveratol supplements because they interact with products like blood thinners. Two common inflammatory medications that thin blood are aspirin and ibuprofen. This is one of the side effects of resveratrol supplements and may increase the risk of bleeding. Should check with your doctor.
What Resveratrol Side Effects Might I Incur?
As of 2011, the most recent evidence suggests that resveratrol has no prominent side effects. However, further studies are needed to ensure its safety for pregnant and nursing women. If pregnant, be on the safe side and avoid its use until more information is available. Resveratrol is a natural supplier of estrogen, a female reproductive hormone that fuels the development of breast cancer. Therefore, women at high risk of breast cancer should not consume resveratrol. Another side effect of resveratrol is that it may also decrease the therapeutic effects of anticoagulants, such as warfarin, and could increase the risk of bleeding.
Without long term studies to examine or look at, the best we can do in terms of advising on potential resveratrol side effects is to look at information that is not based on facts or a careful long term study. Below are some side effects of resveratrol reported by actual users of the resveratrol supplement. The list is by no means complete nor scientific in nature.
Here are some possible resveratrol side effects:
- Upset stomach
- Jittery feeling or excess energy
- Pain Joints
- Decrease in appetite
- Feeling Light Headed
The problem with this reported information is, the side effects may have been caused by resveratrol or some other ingredient like a filler in the supplement. Plus there is the fact that some of users simply might not report any side effects of reveratrol.
Can I Minimize the Side Effects of Resveratrol?
Stomach and diarrhea related side effects can be linked back to a ingredient called emodin. It is used as a filler. Since emodin can cause diarrhea, and has no positive health benefits, you need to stay away from it. But of course it is not all that easy, see emodin is not normally listed on the label.
To Minimize Side Effects Beware of Resveratrol Blends
Some resveratrol supplements makers are blending in a number of ingredients together to try to convince you that they have a wonder blend. As a user, you may experience side effects from resveratrol blended products and believe you are having a reaction from one of the resveratrol side effects. But the so called side effects of resveratrol could be caused by any of the other ingredients in the blend. Again the other ingredients may not be listed.
A jittery feeling is one of the resveratrol side effects reported. Because we don’t know what is in some resveratrol supplements maybe this was blended with caffeine.
Our advice is to do your homework, and look at the ingredients. Stick with a resveratrol supplement that is blended with natural, pure ingredients if you want to reduce the risk of resveratrol side effects. Make sure that there is no lead in the product from the manufacturing process. A good company that I use to check out supplements is www.ConsumerLab.com.
For Your Further Study
In 2002, the National Institute of Environmental Health Sciences commissioned a report, “Trans-resveratrol Review of Toxicological Literature.” A review of more than 200 referenced scientific studies showed that there were no reported adverse side effects from Resveratrol on humans. Massive dosage studies were also performed on animals. “They observed no adverse affect level (NOAEL) was 300 mg/kg/day,” which would be a human equivalent dosage of 30,000 mg or 10–100 times the concentrations contained Vindure 900.
Always Consult Your Doctor
It is very important that you consult your doctor before starting any supplementation program. We are not giving any medical advice in this article or website. We are just passing on information that is available on the web.
As with anything you take, there can be resveratrol side effects and there can be interactions with your medications, so you need to check with your Doctor before taking resveratrol supplements. Especially if you are using a blood thinner.
