Resveratrol side effects notwithstanding, this is the antioxidant compound in red wine that has been linked with all sorts of healthy properties, like a decreased risk of cardiovascular disease. But many of the studies in support of resveratrol have used much higher levels of the compound than you will get from a glass or two of red wine. So if you want to get some of those famous resveratrol health benefits, you may need to use a supplement. But that raises another question: can you experience resveratrol side effects from taking too much? And are they serious enough to influence whether or not you buy resveratrol?

Resveratrol Benefits

What do you have to gain by taking a resveratrol supplement? Its main benefit seems to be cardiovascular. How does it work? And are the benefits worth any potential resveratrol side effects?

A lot of people talk about cholesterol like it’s the devil, but the truth is, cholesterol by itself isn’t a bad guy. In fact, it’s vital, and you’d die without it! The reason it gets a bad reputation is because it can lead to stroke or heart attack when it becomes oxidized or inflamed. Well, it just so happens that as an antioxidant, resveratrol helps to reduce oxidation and inflammation of your cholesterol!

Resveratrol might also help prevent clotting in your blood (which can also lead to heart attack and stroke).

Lastly, I want to mention that there are also resveratrol anti aging benefits. As an antioxidant, resveratrol can help to diminish the effect of the sun's ultraviolet rays on your skin. This will help prevent wrinkles and other signs of aging. The reason I'm going through all these benefits is to put the resveratrol side effects into context.

Resveratrol Cancer Benefits

I also want to quickly mention that there are specific resveratrol cancer benefits. Cancer is such a killer these days that we need to do whatever we can to avoid it. The scariest part about cancer is that we never know who's going to get it, or why--not counting people like smokers.

But we do know that there are some vitamins, minerals, and other nutrients that help prevent it, and resveratrol is one of those. One study showed that resveratrol lead to a destruction of pancreatic cancer cells. An article on explains that resveratrol may help to prevent breast cancer before it even begins.

These resveratrol cancer benefits are yet another reason not to get too worked up over a few resveratrol side effects.

Resveratrol Foods

In addition to red wine (the most famous source of resveratrol), you can also find this antioxidant in foods like peanuts, grapes, blueberries, cranberries, and bilberries.

Resveratrol Side Effects

Here are some possible side effects you can experience from taking resveratrol:

  • Upset stomach or diarrhea. This resveratrol side effect is sometimes associated with consuming high amounts of low-quality resveratrol.
  • Insomnia. This resveratrol side effect is rare, but some people have reported a sense of anxiety from taking this product. In some cases, this is serious enough to lead to insomnia.
  • Joint pain. This has occurred in those taking an extremely high dose. If you experience this resveratrol side effect, try lowering your dose and it should go away.
  • Drug-drug interactions. If you’re taking any blood-thinning medications, talk to a doctor before you buy resveratrol due to potential complications.

Ways to Avoid Resveratrol Side Effects

Some of the side effects listed above don’t come from the compound itself, but from other additivies in the supplement. Some supplements are made from Japanese knotweed, which is high in emodin. There are no particular benefits associated with emodin, and it might even be the cause of some of the resveratrol side effects I've described. In short, it’s best to take a high-quality product.
