How We Ranked
Every resveratrol supplement claims to give your body antioxidants to target inflammation. However, not all resveratrol supplements are made equal. Some are better than others.
To separate the best and worst resveratrol supplements, our editorial team considered all of the following:
Resveratrol Dosage: You’re buying a resveratrol supplement for the resveratrol. That’s why resveratrol dosage was one of our most important ranking factors. The higher the resveratrol dosage, the more active ingredients end up in your body. The top-ranked resveratrol supplements on our list have dosages of 200mg to 500mg of resveratrol per capsule, while lower-ranked resveratrol supplements have dosages of 10mg to 40mg.
Complementary Ingredients: Although resveratrol is the most important ingredient in a resveratrol supplement, we also considered complementary ingredients in our rankings. Some ingredients (like black pepper extract or Bioperine) boost the absorption of resveratrol, for example, while other ingredients complement the effects of resveratrol. With their own antioxidant capabilities.
Ingredient Transparency & Labelling: Some resveratrol supplements use proprietary labels or unclear labeling to hide their origins, concentration, and ingredient sources. We preferred resveratrol supplements with transparent labeling.
Price & Value: Some people want to pay $70 for a one month supply of a supplement, while others want to pay $20. We featured several resveratrol supplements for all different budgets, although we emphasized good value at every price to ensure users got the most bang for their buck.
Advertised Benefits & Honesty: Resveratrol has been linked to anti-cancer effects in some small studies. However, that doesn’t mean resveratrol supplements can advertise themselves as a cure for cancer. Some studies show resveratrol can help with weight loss, but that doesn’t mean you’ll lose 30lbs in a week with no diet or exercise. We were wary of resveratrol supplements that made dishonest claims about their ability to treat or prevent diseases. By FDA regulations, supplement cannot advertise themselves as a treatment, cure, or preventative measure for diseases or illnesses.
Manufacturer Reputation & History: Good resveratrol supplement companies have a proven track record of creating effective supplements with transparent ingredients at an approved location. We weren’t biased against new resveratrol supplement companies. However, we preferred companies with the highest degrees of quality and transparency.
What is Resveratrol?
Resveratrol is a plant-based chemical with antioxidant properties. Strong doses of resveratrol are found in red wine, grapes, and certain berries and peanuts.
Instead of drinking 100 glasses of red wine per day for resveratrol, some people take resveratrol supplements to get an equivalent dose. A resveratrol supplement contains a concentrated, high dose of resveratrol. This dose may support inflammation throughout the body, helping to support various benefits.
The average glass of red wine contains around 0.5mg of resveratrol. In comparison, the top-ranked resveratrol supplements on our list contain 250mg to 500mg of resveratrol per serving. It’s like drinking 50 to 100 glasses of red wine!
Resveratrol is found in particularly high concentration in the skins and seeds of grapes and berries. Some supplements get their resveratrol from grape skin extract, for example. Others get it from other parts of grapes or berries.
Benefits of Resveratrol: What Does Science Say?
There’s evidence showing that resveratrol can support various benefits. Although some studies have been performed on humans, others have been performed on animals or human cells in test tubes. We’ll review that evidence below to share the best, most science-backed benefits of resveratrol.
Resveratrol is best-known for its anti-aging benefits. Many people take resveratrol supplements daily for their purported effects on aging, lifespan, wrinkles, and more.
Studies have shown that resveratrol could extend lifespan and support various anti-aging benefits. In this study, for example, researchers found that resveratrol activated certain genes that fight off diseases and aging. A similar study found that taking a resveratrol supplement was similar to restricting calories: both restricting calories and taking resveratrol appear to extend lifespan.
One of the biggest and most-shared reviews on resveratrol was published in 2016. Researchers reviewed evidence on resveratrol and concluded that resveratrol increased lifespan in 60% of the organisms studied. This effect was most prominent in organisms with little relation to humans (like worms and fish). However, it’s possible resveratrol exhibits some type of lifespan-increasing effect.
Many people take resveratrol supplements for cardiovascular health and blood pressure. Some studies show resveratrol can help lower blood pressure. In this 2015 review, researchers found that high doses of resveratrol could help reduce the pressure exerted on artery walls when the heart beats, also known as your systolic blood pressure (the upper number in your blood pressure readings). This number increases with age as arteries stiffen. When the number is high, it indicates a higher risk of heart disease.
Researchers believe resveratrol impacts cardiovascular health by raising nitric oxide (NO) levels in the bloodstream. Your body produces nitric oxide to widen and relax blood vessels. When you have higher levels of NO, you tend to have lower blood pressure. In this 2008 study published in Hypertension, researchers found that wine polyphenols (including resveratrol) improved blood vessel performance in rats with high blood pressure.
Resveratrol also seems to have a positive effect on blood fats (i.e. your cholesterol). Several studies have shown that resveratrol supplements could change blood fats in a healthy way. In this 2014 study, for example, researchers gave resveratrol to mice with cholesterol issues, finding that resveratrol effectively reduced blood lipid levels in mice. Similarly, this 2016 study found that resveratrol lowered cholesterol levels in mice even when they were fed a high-fat diet. Researchers found that resveratrol reduced the body weight and total cholesterol levels of mice while increasing levels of ‘good’ (HDL) cholesterol.
Researchers believe resveratrol affects cholesterol by oxidizing ‘bad’ (LDL) cholesterol in your bloodstream. As resveratrol travels through your bloodstream, it neutralizes and destroys bad cholesterol, including the LDL oxidation that builds plaque within your artery walls.
Researchers have observed the cholesterol lowering effects of resveratrol in humans. In this study, researchers gave participants a high dose of resveratrol daily for six months. After six months, researchers found that ‘bad’ (LDL) cholesterol had dropped by 4.5% and oxidized LDL had dropped 20% compared to participants taking a placebo.
Resveratrol is also prized for its neuroprotective effects. Many people take resveratrol supplements to support brain health, ward off the cognitive effects of aging, and support overall cognition. Multiple studies have shown that red wine can slow down cognitive decline, and many researchers believe this effect is attributed to resveratrol. In this 2014 study, for example, researchers found that the resveratrol in red wine appeared to slow the progression of Alzheimer’s disease and other degenerative brain conditions.
Researchers believe resveratrol impacts Alzheimer’s disease because of its effects on beta-amyloids. Beta-amyloids are chemicals that form plaque within the blood vessels of the brain, increasing the progression of Alzheimer’s disease. The antioxidant effects of resveratrol could fight this plaque, reducing the progression of Alzheimer’s.
Other studies show resveratrol could help with diabetes. Although most studies have occurred on animals, studies suggest that resveratrol may help increase insulin sensitivity. To do that, resveratrol appears to stop an enzyme from turning glucose into sorbitol, a sugar alcohol. Sorbitol causes oxidative stress in diabetics, making the condition worse.
Resveratrol could help diabetics in other ways. In one review study, researchers found that resveratrol helps people with diabetes in multiple areas of the body. Researchers found resveratrol can protect against oxidative stress, decrease inflammation, and activate AMPK in diabetics, for example.
Others take resveratrol to ease joint pain. Studies suggest that resveratrol could target inflammation within the joints, increasing mobility and reducing pain. In this study, for example, researchers found that resveratrol may help cartilage from deteriorating. Cartilage breakdown is one of the main causes of joint pain. In another study, researchers injected resveratrol directly into the knee joints of rabbits with arthritis and found they experienced less damage to cartilage.
One of the most important areas of resveratrol research lies in its anti-cancer effects. Multiple studies have suggested that resveratrol could inhibit cancer cell growth, change the gene expression of cancer cells to inhibit growth, and affect cancer in other ways. In separate studies, resveratrol has been shown to fight several types of cancer cells, including gastric, colon, skin, breast, and prostate cancers. In most of these studies, researchers found that resveratrol inhibited cancer cell growth, which could help prevent cancer cells from replicating and spreading.
One of the biggest problems with resveratrol is its bioavailability. Some researchers believe your body doesn’t absorb resveratrol easily. In this 2011 study, for example, researchers found that little resveratrol is absorbed by your body when taking resveratrol supplements orally. However, researchers and supplement companies are constantly searching for new ways to make resveratrol more bioavailable.
Overall, resveratrol is an exciting area of research. However, we need more large scale research in humans to verify these effects. As more research on resveratrol gets revealed, we’re learning more about its powerful health supporting properties.
Most resveratrol supplements contain 50mg to 300mg of resveratrol per serving. The best resveratrol supplement contain 250mg to 600mg of resveratrol per serving.
Some experts believe you can experience the benefits of resveratrol with as little as 5 to 10mg per day. Other studies have tested doses as high as 2,500mg or 5,000mg.
For most purposes, however, you can enjoy the benefits of resveratrol with a dose of around 10mg to 50mg per day.
Taking higher doses of resveratrol may not be a good idea. In this 2016 study, for example, researchers found participants developed a fever when taking more than 1,500mg of resveratrol daily for six months. Similarly, this study found that taking 2,500mg of resveratrol daily for an extended period was linked with nausea, vomiting, diarrhea, and liver dysfunction.
Other studies, however, have shown that resveratrol is safe to take even in doses up to 5,000mg per day.
Side Effects of Resveratrol
Studies on resveratrol have revealed few major risks. When used by healthy adults in normal dosages, resveratrol is tolerated well by adults.
However, there’s limited information about the safe dose of resveratrol for humans. There’s also limited research on resveratrol’s interactions with medications.
In high doses, resveratrol could reduce the clotting ability of blood, which could increase bleeding or bruising. This could cause interactions with anti-clotting drugs like heparin or warfarin. Talk to your doctor before taking resveratrol if you are taking medication or have any type of medical condition.
One study found that resveratrol was a “double edged sword” because it was associated with health problems at higher dosages. Researchers found that taking 2.5g of resveratrol or more per day was associated with nausea, vomiting, diarrhea, and liver dysfunction. Another study, however, found that a 5g daily dose of resveratrol was safe for most healthy adults.
Overall, most people experience zero side effects when taking normal doses of resveratrol.
