Resveratrol
A polyphenol antioxidant found in grapes and berries, studied for supporting cardiovascular and skin health.
Quick Answer: 30-Second Overview
- Resveratrol is a natural polyphenol found in red grapes, berries, and peanuts.
- It is known for its antioxidant properties and potential to support cardiovascular health.
- Trans-resveratrol is the biologically active form most commonly used in supplements.
- Research has examined its link to sirtuin activation and healthy aging.
- Common supplemental doses range from 100 mg to 500 mg per serving.
What IsResveratrol?
Resveratrol is a stilbenoid, a type of natural phenol produced by certain plants in response to stress, injury, or fungal infection.
It is most abundant in red grape skins, which is why red wine has been a primary focus of research.
Resveratrol exists in two forms: cis-resveratrol and trans-resveratrol. The trans form is the more biologically active and stable variant.
As a polyphenol antioxidant, resveratrol helps neutralize free radicals and may support the body's defense against oxidative stress.
The compound gained widespread attention due to the "French Paradox"—the observation that French populations had relatively low rates of cardiovascular disease despite a diet high in saturated fats.
How It Works in the Body
Antioxidant Activity
Resveratrol neutralizes free radicals and reactive oxygen species, supporting the body's antioxidant defenses.
Sirtuin Activation
Resveratrol has been studied for its ability to activate SIRT1,, a sirtuin enzyme involved in cellular health and longevity pathways.
Anti-Inflammatory Support
Research suggests resveratrol may modulate inflammatory pathways, including NF-kB and COX-2 signaling.
Cardiovascular Support
Resveratrol may support endothelial function, healthy blood vessel dilation, and lipid metabolism.
Potential Health Benefits
Cardiovascular Health
Resveratrol may support heart health through its antioxidant activity, endothelial function, and healthy lipid metabolism.
Skin Wellness
Antioxidant properties may help protect skin from environmental oxidative stress and support a youthful appearance.
Anti-Aging Support
Resveratrol's sirtuin activation and antioxidant activity make it a compound of interest in aging research.
Metabolic Wellness
Some studies suggest resveratrol may support insulin sensitivity and metabolic health markers.
Brain Health
Preliminary research examines resveratrol's potential neuroprotective effects via antioxidant and anti-inflammatory mechanisms.
Scientific Evidence Overview
Extensive laboratory studies show that resveratrol has antioxidant, anti-inflammatory, and sirtuin-activating properties at the cellular level.
Animal studies show promising results for extending lifespan and improving metabolic health, though outcomes vary by species and dosage.
Human clinical trials are more limited. Some studies show improvements in inflammatory markers and endothelial function, but results are mixed.
Resveratrol has low oral bioavailability due to rapid metabolism. Micronized and liposomal formulations may improve absorption.
Important:Dietary supplements cannot replace a balanced diet, adequate sleep, regular exercise, or medical treatment. Individual results may vary.
Natural Food Sources
Red Grapes
The skin of red grapes is the richest dietary source of resveratrol.
Red Wine
Contains resveratrol extracted from grape skins during fermentation.
Blueberries
Contains small amounts of resveratrol and other beneficial anthocyanins.
Cranberries
A source of resveratrol and other polyphenol antioxidants.
Peanuts
Skin contains trace amounts of resveratrol.
Japanese Knotweed
Polygonum cuspidatum is a primary commercial source of resveratrol supplements.
Dosage & Usage
| Form | Typical Dose | Timing |
|---|---|---|
| Trans-Resveratrol Capsules | 100-500 mg per serving | Take with food, preferably with a source of fat for better absorption. |
| Micronized Resveratrol | 100-250 mg per serving | Enhanced absorption formula, take with or without food |
| Liposomal Resveratrol | 50-200 mg per serving | Liposomal delivery may enhance bioavailability |
Always follow label directions and consult a healthcare professional for personalized guidance.
Who May ConsiderResveratrol
Adults who prioritize heart health
For those seeking to support heart health with antioxidants and endothelial support.
Skin wellness enthusiasts
For individuals seeking internal antioxidant support to protect and brighten their skin.
Healthy aging advocates
People interested in sirtuin activation and longevity-related supplements.
Active adults
For those seeking antioxidant support to complement an active lifestyle.
Safety & Interactions
General Safety
Resveratrol has been studied at doses up to 1000mg daily, with generally good tolerability. Mild digestive effects may occur at higher doses.
Blood Thinner
Resveratrol may have mild antiplatelet effects. Individuals taking anticoagulant medications should consult a healthcare professional.
Hormone-Sensitive Conditions
Resveratrol has weak estrogenic activity. Individuals with hormone-sensitive conditions should consult a doctor before use.
Drug Interactions
Resveratrol may affect the metabolism of certain medications through CYP450 enzyme interactions. Consult your healthcare provider.
How to Choose a Quality Product
- Look specifically for trans-resveratrol, as it is the more biologically active form.
- Check the label for the amount of trans-resveratrol per serving, not just total resveratrol.
- Consider micronized or liposomal formulations for enhanced bioavailability.
- Select brands that offer third-party testing and COA documentation.
- Prefer products from cGMP-certified, FDA-registered manufacturing facilities.
Ingredient Comparisons
Resveratrol vs. NMN
Resveratrol is an antioxidant polyphenol; NMN is an NAD+ precursor. They work through different mechanisms but are sometimes combined for complementary support.
Resveratrol vs. Quercetin
Both are polyphenol antioxidants. Quercetin, a flavonoid found in onions and apples, may work synergistically with resveratrol, a stilbenoid from grapes.
Trans-Resveratrol vs. Regular Resveratrol
Trans-resveratrol is the more stable and biologically active form. Regular resveratrol supplements may contain a mix of cis and trans forms.
