What is Resveratrol?
Resveratrol is a naturally occurring substance found in some plants. It’s classified as a polyphenol, a type of compound known for its antioxidant properties.[1] Plants produce resveratrol as a defense mechanism against injury and disease.[2]
Resveratrol was first identified by scientists in 1939, but it didn’t attract significant interest until the 1990s.[3] This shift in attention occurred when researchers began exploring its potential link to the health advantages associated with red wine.[4]
Resveratrol is categorized as a stilbenoid, which is a specific type of plant compound.[5] Its unique chemical structure allows it to interact with different molecules inside the body.[6] This interaction is thought to be the basis for resveratrol’s potential positive effects on health.
Natural Sources of Resveratrol
Plant-Based Sources
Resveratrol is produced by various plants under certain conditions. It often appears in response to stress, such as injury or exposure to pathogens. Common plant sources include the skin of grapes, blueberries, and peanuts.[7]
The quantity of resveratrol found in plants can differ. Factors like the climate, how the plants are grown, and the specific type of plant influence these levels.[8] For example, grapes grown in cooler temperatures often have a higher resveratrol content.[9]
Here are some common food sources that contain resveratrol:
- Red grapes
- Blueberries
- Cranberries
- Peanuts
- Pistachios
- Dark chocolate
Red Wine and Grapes
Red wine and grapes are among the most well-known sources of resveratrol. The compound is concentrated in the grape skins. Red wine has higher levels than white wine because it’s fermented with the grape skins still included.[10]
The amount of resveratrol varies across different kinds of grapes. Environmental factors also play a significant role. Grapes that have been exposed to fungal pressure tend to generate more resveratrol as part of their defense response.[11]
Here’s a table outlining the resveratrol content in various wine and grape products:
Product | Resveratrol Content (mg/L) |
---|---|
Red wine | 0.1 – 14.3 |
White wine | 0.1 – 2.1 |
Red grape juice | 1.14 – 8.69 |
White grape juice | 0.05 – 1.08 |
Health Benefits of Resveratrol
Cardiovascular Health
Resveratrol may provide benefits to the heart in several ways. Research suggests it might help improve cholesterol and blood pressure levels.[12]
Studies indicate that resveratrol could reduce inflammation within blood vessels.[13] This reduction may contribute to preventing plaque buildup, a cause of heart disease. Some studies also suggest that resveratrol might improve how well blood vessels function.
It’s important to know that most studies on resveratrol have been conducted using animals or in laboratory settings.[14] More research involving human subjects is necessary to verify these results. Also, the doses of resveratrol used in studies are often higher than those obtained through diet.[15]
Anti-Inflammatory Effects
Numerous studies have indicated that resveratrol possesses anti-inflammatory properties.[16] Inflammation is a factor in many chronic illnesses. Therefore, by reducing inflammation, resveratrol may help prevent or manage these conditions.
Research suggests resveratrol can hinder inflammatory molecules in the body.[17] It might also activate certain genes that help fight inflammation.[18] These effects have been observed in both animal and human research.
Here are some health conditions that may benefit from resveratrol’s anti-inflammatory effects:
- Arthritis
- Heart disease
- Diabetes
- Alzheimer’s disease
- Some types of cancer
Antioxidant Properties
Resveratrol is a notable antioxidant. Antioxidants protect cells from damage caused by free radicals.[19] Free radicals are unstable molecules that can harm DNA and other cell structures.
By neutralizing free radicals, resveratrol may help prevent cellular damage. This could potentially slow down the aging process and reduce the likelihood of certain diseases. Some studies suggest resveratrol may be more effective than vitamins C and E in specific antioxidant functions.[20]
The antioxidant characteristics of resveratrol could offer protection against:
- Heart disease
- Cancer
- Alzheimer’s disease
- Parkinson’s disease
- Age-related macular degeneration
Potential Cancer-Fighting Properties
Resveratrol has shown promise in studies related to cancer. Lab and animal experiments suggest that it could help prevent cancer cells from growing and spreading.[21]
Various ways resveratrol could potentially fight cancer have been suggested. It might disrupt the growth and division of cancer cells.[22] Resveratrol may also trigger the death of these cells.[23] Some studies indicate it could make cancer cells more responsive to chemotherapy.[24]
It’s important to understand the limits of current research. Most of the studies have been done in laboratories or with animals. Human studies are limited, and they have produced varying results. More research is needed to know if resveratrol can effectively help prevent or treat cancer in humans.
Resveratrol and Longevity
The “French Paradox”
The term “French Paradox” describes the observation that people in France have low rates of heart disease.[25] This is despite a diet that is high in saturated fats. Some researchers have proposed that red wine consumption might be part of the explanation.[26]
This theory brought more interest to resveratrol, a substance found in red wine. Scientists wanted to know if resveratrol could be responsible for the potential heart-protective effects of red wine.
However, further research has revealed a more complex picture. The French diet also includes many other healthy foods. These include fresh fruits, vegetables, and whole grains. Lifestyle habits, such as physical activity, also contribute. While resveratrol might have some health benefits, it’s likely not the sole reason for the French Paradox.[27]
Calorie Restriction Mimetic
Resveratrol is being studied as a potential calorie restriction mimetic. Calorie restriction is known to extend life in several species.[28] A calorie restriction mimetic is a substance that produces similar effects to calorie restriction, without actually reducing food intake.
Studies suggest that resveratrol might activate certain proteins called sirtuins.[29] Sirtuins play a role in aging and how the body uses energy. By activating these proteins, resveratrol might generate some of the same benefits as calorie restriction.[30]
Animal studies have shown positive results. Resveratrol increased the lifespan of yeast, worms, and fish.[31] It also improved the health of mice that were fed a high-calorie diet. However, there aren’t many human studies in this area. More research is required to determine if resveratrol can mimic calorie restriction in humans.
Absorption and Bioavailability
The way resveratrol is absorbed by the human body is intricate. When ingested, it is quickly absorbed in the intestines. However, the liver also rapidly breaks it down.[32] This results in very little resveratrol actually reaching the bloodstream.[33]
Several factors influence how much resveratrol the body can use. These include the type of food it’s in, how it’s taken, and individual differences in how the body processes it. For instance, consuming resveratrol with a meal that contains fat might improve how well it’s absorbed.[34]
Here is a table that compares how well resveratrol is absorbed from various sources:
Source | Bioavailability |
---|---|
Red wine | Low |
Grape juice | Low |
Whole grapes | Medium |
Supplements | Variable |
Researchers are currently looking for ways to make it easier for the body to absorb resveratrol. Some of these strategies include:
- Using more bioavailable forms of resveratrol
- Combining resveratrol with other compounds that enhance absorption
- Developing novel delivery systems, such as nanoparticles
Resveratrol Supplements
Types of Supplements
Resveratrol supplements are available in several forms. These include capsules, tablets, powders, and liquid extracts. Some supplements contain pure resveratrol, while others have a mix of compounds.
Here is a list of common types of resveratrol supplements:
- Trans-resveratrol (the most active form)
- Resveratrol from Japanese knotweed extract
- Grape seed extract with resveratrol
- Red wine extract
- Mixed polyphenol supplements containing resveratrol
When choosing a supplement, it’s important to consider factors such as purity, dosage, and whether it has been tested by a third party.[35] Look for products that specify the amount of trans-resveratrol they contain.[36] This is the form that has been most studied for its health effects.
Dosage and Safety
The dosage of resveratrol in supplements can vary quite a bit. Most studies have used doses ranging from 150 mg to 1000 mg per day.[37] However, the ideal dose for humans is not yet known.
While resveratrol is generally considered safe, it may cause some side effects in certain individuals. These can include:
- Nausea
- Stomach upset
- Headache
- Fatigue
Resveratrol could interact with some medications. It may affect how the liver breaks down drugs.[38] This could potentially increase the risk of side effects from those medications.
Always consult a doctor before starting any new supplement.[39] This is particularly important if you have pre-existing health conditions or are taking medications. They can help determine if resveratrol supplements are appropriate for you and what dosage to use.
Research and Clinical Studies
Resveratrol has been extensively studied. Much of the early research involved laboratory experiments and animal studies. In recent years, more studies involving humans have been conducted.
Animal studies have shown promising results regarding heart health, diabetes, and cancer prevention.[40] However, human studies have shown mixed results. Some studies have demonstrated benefits, while others have not found significant effects.[41]
Here’s a timeline highlighting significant milestones in resveratrol research:
- 1939: Resveratrol first isolated from white hellebore
- 1992: Resveratrol identified in red wine
- 1997: First study suggesting anti-cancer effects
- 2003: Study showing resveratrol extends lifespan in yeast
- 2006: Resveratrol improves health of mice on high-calorie diet
- 2010: First long-term study of resveratrol in humans published
- 2015: Meta-analysis shows resveratrol may improve some cardiovascular risk factors
Current research is focused on identifying effective doses for humans.[42] Scientists are also studying how resveratrol interacts with other compounds in the body. Further long-term human studies are necessary to fully understand resveratrol’s effects.
Incorporating Resveratrol in Your Diet
Adding resveratrol to your diet doesn’t require significant changes. This compound is found in many healthy and delicious foods. The key is to eat a balanced diet that includes a variety of plant-based options.
Grapes are an excellent way to consume resveratrol. Try including them in your breakfast or as a snack.[43] Berries such as blueberries and cranberries also contain resveratrol and make great additions to yogurt or oatmeal.[44]
Here is a list of recipe ideas that are rich in resveratrol:
- Berry smoothie with mixed berries and grape juice
- Spinach salad with red grapes and chopped peanuts
- Dark chocolate-covered berries for dessert
- Homemade trail mix with peanuts and dried cranberries
Remember that moderation is important. While red wine contains resveratrol, drinking too much alcohol can be harmful to your health.[45] If you choose to drink, follow the recommended guidelines.
While supplements are an option, it is generally better to get nutrients from whole foods whenever possible. Foods contain a variety of beneficial compounds that work together.[46] This combination of compounds may offer more advantages than isolated supplements.
