Best Resveratrol Supplements Tested & Reviewed
A natural compound in red wine that may have potent anti-aging and disease-fighting properties, and it’s being sold in supplement form. You may have noticed all the buzz about the antioxidants in red wine over the past few years, and resveratrol is the reason behind it.
Resveratrol is a natural compound (polyphenol) found in red grape skin, cocoa, Japanese knotweed, peanuts, blueberries, and some other berries. It’s a powerful antioxidant produced by plants to protect them against environmental stresses such as fungal diseases and sun damage.

Most resveratrol capsules sold in the U.S. contain extracts from an East-Asian plant abbreviated P.C. Other resveratrol supplements are made from red wine or red grape extracts. To help you sort through the wide variety of the best resveratrol supplements, we’ve assembled a list of products for the best value.
What is resveratrol?
How does it work?
It’s a stillbenoid, a type of natural phenol, and a phytoalexin (an antimicrobial compound) produced naturally by several plants in response to injury or when the plant is under attack by pathogens like bacteria or fungi. If that seems too complicated, it’s basically a compound produced by plants to fight off disease–and researchers are theorizing that it could help us fight off aging and disease, too.
Grapes produce resveratrol in their skin to protect the plant against fungal diseases and sun damage. Red wine contains small amounts of resveratrol. That’s why you’ll most commonly hear about resveratrol supplements in relation to wine; it has higher levels of the natural compound compared to other natural food. Overall, red wine contains less than 1-2 mg of resveratrol in 8 oz. However, red wine has more resveratrol than white wine because red wines are fermented with the grape skins longer.

Many of us have heard the saying that drinking a glass of red wine at dinner is healthy because it contains antioxidants. There is one particular antioxidant inside that is especially helpful and full of benefits: Resveratrol.
Specifically, Resveratrol is a flavonoid antioxidant and is a part of a group of compounds called polyphenols. They help to protect against damages that may happen inside the body. Luckily, this supplement can be found in the skin of red grapes, berries, and even peanuts. Usually, Resveratrol is extracted from either red wine or grapes and placed into a supplement with polygonum cuspidatum, which is extracted from an Asian plant. All around, it’s one of the more natural supplements you can introduce into your health routine.
Long Lasting Benefits
The benefits of including a daily intake of this supplement can affect many parts of your life and last a long time. Many studies have been conducted, and doctors have found proof that with the right dosage, these benefits can be achieved. Here are just some of that Resveratrol can provide.
Resveratrol can help reduce inflammation and bad cholesterol around the heart that can lead to heart disease. It also makes it more difficult for blood clots to form, which can lead to a heart attack.
It won’t completely prevent cancer from happening but it can help to reduce the spreading of cancer cells and even start to fight back.
Resveratrol can make those pesky fat cells die. It helps to inhibit the fatty acid synthase, also known as lipoprotein lipase and works to break down the fat tissue. It also aids in boosting your metabolism.
The supplement can assist in preventing insulin resistance. This condition occurs when the body becomes decreasingly sensitive to the blood-glucose-reducing hormone, insulin. This can happen to many of us over time so it’s important to implement something like this if your family has a history of the disease.
How to Use it
Sure, you could try to drink red wine more often but it would take over 150 glasses of red wine a day to get the right amount. So we suggest a much easier route by taking it in pill form. The supplement is usually measured out to about 30 – 50 mg per capsule. Taking more than 250 mg a day is not recommended, however so be sure to not take more than about 5 a day.
Potential Side Effects
Luckily, since this supplement has mainly natural ingredients, the side effects are nothing severe, even in high doses. However, it can interact with blood thinners such as aspirin or ibuprofen and can raise the risk of bleeding. Some may be sensitive and can experience some nausea.
Always check with your doctor if you are on certain prescriptions to make sure that the supplement won’t have adverse affects with what you are taking.
Why Take Resveratrol Daily?
Since the levels of resveratrol are so low in red wine, cocoa, and certain berries, daily supplements are an easy way to get an antioxidant boost with very little effort. Remember that this supplements typically contain far lower dosages than the amounts used in research studies that produced beneficial results. Most contain 250-500 mg of resveratrol; to get the equivalent dose in some animal studies, a person would have to consume 2gm of resveratrol or much more a day. However, you can’t overdose on resveratrol and take even a small amount will provide some antioxidant benefits. These could include enhanced endurance, cardiovascular security, decrease inflammation, lower LDL or “bad” cholesterol, a testosterone boost in men, increased mental sharpness, the prevention of diabetes, decreased risk of heart attack, and increased longevity. There are many possible health benefits to taking resveratrol supplements (not all of them well-researched), and we will examine them next.
Health Benefits of Resveratrol
Resveratrol supplements could enhance or even replace endurance training results by providing skeletal muscle benefits that are similar to endurance training. A study conducted in 2012 on rats indicated that the use of resveratrol showed an increase of stamina, metabolism and also improved heart function. Interestingly enough, the grouping of training with this supplement resulted in a significant increase in performance! That means those who hate endurance training could potentially skip it and take a supplement instead. However, to see the best results, consider combining endurance training with resveratrol supplementation.
Resveratrol, like many other antioxidants, may also be able to reduce the risk of cardiac disease. According to trusted organizations like the CDC, heart disease has been an important cause of death in the US. Other studies indicated that drinking small portions of five-ounce glasses of wine in a day decreased the risk of developing clogged arteries. This risk reduction overall reduced the risk of mortality by almost thirty percent! Taking the lead from this study, other researches were conducted and indicated that resveratrol works on the heart and provides it with good protection to avoid incidences like heart attacks.
The resveratrol benefits don’t stop at heart disease. Antioxidants can help prevent or even slow down cancer. Colon cancer is the most frequently occurring digestive system cancer, and it can be one of the deadliest. A 2005 French study found that resveratrol was able to delay the production of cancerous cells and therefore could be considered a useful anti-cancer agent.
For many people, vision loss is an accepted part of the aging process. A 2010 study by Missouri researchers found that resveratrol has the ability to regulate angiogenesis, preventing the abnormal growth of blood vessels that are damaging to eyesight. Consider eating foods healthy for the eyes, such as omega-3 fatty fish and foods rich in beta-carotene, vitamin C, and vitamin E.
Men who suffer from declining testosterone levels due to age should visit their doctors and ask for a blood test to determine their levels. Testosterone is a key hormone that regulates body weight, muscle mass, mood, libido, and many other important characteristics of the male body. According to a Korean study conducted in 2008 on mice, resveratrol consumption might be able to help. The researchers found that blood testosterone concentration improved by more than 50% following a 28-day period of supplement intake.
Resveratrol has great health benefits for the body, but it also can improve brain function. One way to sharpen your mind is through increased blood flow to your brain. A 2009 study conducted by Illinois researchers found that mice receiving resveratrol supplementation had a better memory function and overall increased mental performance. In 2010, scientists in the UK studied 22 healthy adults (an admittedly small sample) and determined that neurological blood flow increased following resveratrol consumption. Resveratrol is considered a dietary supplement and is not approved by the U.S. FDA for any indication. Studies containing the correct dosage, use, safety over an extended period of usage, and effectivity have not been conducted.
Do not take Resveratrol if . . .
You have a blood disorder, as the supplement may induce bleeding. You should also be observed by a physician as you use this product. Since resveratrol is dangerous with other blood thinning agents, it should be stopped two weeks prior a surgery and should not be taken for another two weeks post the surgery.
Do not take these supplements or large amounts of natural foods containing it when pregnant or breastfeeding. There is a lack of research in this area to prove safety. it should be kept away from children.
Resveratrol had mild estrogen like activity. Not much is known and until then females with conditions like cancers and other similar issues that are sensitive to estrogen should consult a doctor or physician before taking these supplements.
Resveratrol decreases the activity of these enzymes involved in drug metabolism, but if this effect is significant in human beings has not been studied.
