A question I received from a reader was “What effects does Resveratrol have on menopause?”
Did you take Resveratrol during your menopause? Did you notice any effects on your body ?
We will be trying to figure this out and keep you updated on this topic.
Sorry for the attention grabber, but I wanted to underline that you should consider reducing your daily Resveratrol dose if you experience any of the side effects listed below (joint pain).
Small amounts of Resveratrol can make a difference. If you take a daily dose of 1 to 3 grams of Resveratrol it can already have a great effect.
On a forum, a consumer reported that he noticed a 10% increase in power output and a better overall performance during various cycling tests.
A lower dose of Resveratrol is also recommended because some people reported that Resveratrol has a great inflammatory effect on their body, which is causing increased joint pain for them.
Resveratrol Side Effects to be added:
- - Joint Pain increased
- - Increased inflammatory effects
- - Increased libido
A positive side effect of Resveratrol might be that it can help to increase your libido. Not just some, but many people have reported this now.
My recommendation would be to decrease your daily Resveratrol dose to avoid increased joint pain.
It’s time for another update, user reported more side effects, good and bad. It’s pretty even, but the health benefits totally stand out:
Resveratrol Side Effects:
Bad
- buzzed, hyper feeling (check, we already had that on our list)
- insomnia (check, we already had that on our list too)
- Stomach cramping and diarrhea.
Positive
- Mental abilities improved
- Irritable Bowel Syndrome (IBS) slightly decreased
- People who are doing sports can run longer distances in a shorter time (check, we knew about that)
- Cholesterol Levels decreased (check, we knew about that)
Sharon47 reported some positive side effects:
I have been taking Resveratrol now for 1 month when I started taken Resveratrol my stomach was so blotted after taking Resveratrol I have notice I’m not blotted anymore also one of my c-workers came by my desk and ask me if I had any botox done on my face.
Wow I was shocked your product does work.
Positive Side Effects:
- Less Bloating
- Softer / Healthier Looking Skin
The first side effect “less bloating” is very surprising, because on a forum someone reported that he experienced “Gas and bloated feeling from resveratrol“.
This underlines that the results can vary from person to person. If you take resveratrol you will hopefully experience no bad side effects at all, just like Sharon.

J. Goodman reported:
I have experienced PVC’s (Premature ventricular contraction) on the two occassions. It came on about 4-6 hours after taking the capsule, and lasted for several hours.
More about Premature ventricular contraction on Wikipedia
C. Hopf reported:
Has anyone reported getting a rash after taking Resveratrol? I developed a rash on the inside of my arms and legs.
Unfortunately Mr. Goodman did not mention which resveratrol supplement he was taking. His solution was to simply discard the bottle.
Always keep in mind that this is a consumer report and not a scientific study. There are many other factors that could have played a role here (aside from resveratrol).

Does resveratrol have any side effects?
So, what does the mayo clinic think about resveratrol? Actually, I was a bit disappointed – the mayo clinic does not have an article about resveratrol that includes more details than what you can find everywhere on the web.
But here are some other interesting facts, according to a study that I read, resveratrol can also help with diabetes, obesity and other diseases. It can lower the risk of inflammation and blood clotting and therefore lower the risk of heart diseases.
There aren’t many (if any) studies of side effects in human, therefore we have to rely on consumer reports. Is that sufficient? I believe yes! Other studies proof that resveratrol is a natural compound that is not toxic even if it is consumed in large doses. Many positive effects have been reported by consumers repeatedly and according to them, resveratrol has much more health benefits than (if any) side effects.
Conclusion? Take resveratrol, but start slowly and increase your dosage when you think you got used to it.
Of course there are many people who take resveratrol. Here are the good and bad effects of resveratrol:

As mentioned, studies about resveratrol have started back in 1996. In 2006, 10 years later, the Mayo Clinic in Rochester still urged that taking resveratol could have negative side effects.
What has changed now in 2009? Do scientists still urge that resveratrol could have a bad effect in humans? No! Studies proofed that the results in monkeys are extraordinary and without any negative side effects at all.
Who should worry about side effects then?
You should not take resveratrol if you have a history of estrogen-sensitive cancers, (breast ovarian/uterine cancers). Also pregnant women should stay away from resveratrol, because there could be some side effects we don’t know of yet. And of course, children should also avoid taking this pill.
So, let’s face it, how effective is resveratrol?
Did you know that studies about resveratrol started a decade ago? Here are some results of the year 1996:

Resveratrol Effects on Lifespan
The lifespan of mice also increased significantly, but at that time the effects of resveratrol were not fully tested on all animals.
According to Wikipedia Later studies proof that mice also have a 30% lower risk of death.
It’s amazing that the saccharomyces can live up to 70% longer. What effects could it have on humans?
There have been studies on monkey that show similar results, but studies on humans haven’t been completed.
Hopefully we will sooner or later be able to say that resveratrol can have such a positive effect on our lives that we can extend it by 30%. That would be great!

Not all side effects have to be negative!
Viagra, originally created to help with chest pains and blood pressure problems, had some positive side effects as we all know nowadays.
