What is resveratrol good for?

Resveratrol is a fascinating polyphenol found in the skins of grapes, berries and nuts. In recent years, it has attracted a great deal of attention – and for good reason. Here are some of its remarkable benefits:

• Cardiovascular health: Resveratrol supports the heart and blood vessels by improving circulation and lowering blood pressure. It may even have a blood-thinning effect and help reduce the risk of heart attacks and strokes.
• Antioxidant properties: This powerful antioxidant neutralises free radicals and protects cells from oxidative stress and damage. This may help prevent chronic diseases.
• Anti-inflammatory effects: Resveratrol reduces chronic inflammation, which is often associated with conditions such as arthritis and chronic heart disease.
• Longevity: Animal studies show that resveratrol may extend lifespan. It activates certain genes associated with ageing.
• Brain health: Resveratrol may improve cognitive function and delay neurodegenerative diseases such as Alzheimer’s disease.
• Diabetes prevention: It increases insulin sensitivity and helps regulate blood sugar levels, which may be particularly beneficial for people with type 2 diabetes.

Key finding: In animal studies, resveratrol is associated with an extended lifespan because it activates genes linked to the ageing process. You can read more about how this mechanism works in our article Resveratrol and longevity.

Should you take resveratrol?

Whether you should take resveratrol as a food supplement depends on your individual health goals and needs. Here are a few points to consider:

• Health benefits: If you are aiming for the benefits mentioned above, resveratrol may be a useful addition to your diet.
• Consulting a doctor: It is always a good idea to consult a doctor before taking a new food supplement, especially if you already take medication or have existing health conditions.
• Natural sources vs. supplements: You can, of course, also obtain resveratrol through food. Supplements, however, provide a concentrated dose and may be convenient for people who do not regularly eat foods rich in resveratrol.

Which foods contain a lot of resveratrol?

If you would like to obtain resveratrol naturally, there are several foods that are rich in this polyphenol:

• Red wine: One of the best-known sources. The fermentation of grapes for red wine increases the concentration of resveratrol.
• Grapes: The skins of red and purple grapes are particularly rich in resveratrol.
• Berries: Raspberries, blueberries and cranberries also contain notable amounts.
• Peanuts: A good plant-based source that can easily be incorporated into the diet.
• Dark chocolate: Also contains small amounts of resveratrol alongside other beneficial polyphenols.

Is resveratrol the same as OPC?

No, resveratrol and OPC (oligomeric proanthocyanidins) are not the same, even though both are powerful antioxidants and offer similar health benefits. Here are the differences:

• Chemical structure: Resveratrol is a single molecule, a stilbenoid, whereas OPCs are a group of compounds belonging to the flavonoid class.
• Sources: Resveratrol is found primarily in grape skins, berries and nuts, while OPCs are abundant in grape seeds, pine bark and certain fruits.
• Function: Both have antioxidant and anti-inflammatory effects, but they act through different mechanisms and have different biological activities in the body.

Conclusion

Resveratrol is a remarkable active compound with many potential health benefits – from supporting heart health to promoting longevity. Whether you should obtain resveratrol through food supplements or natural foods depends on your individual needs and preferences. Remember to consult a doctor before adding new supplements to your routine.

Stay healthy and make use of the benefits of resveratrol to support your well-being.
