HelloPharmacist Scorecard of Organic Resveratrol by Dr. Mercola

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: resveratrol, a compound found in grape skins and red wine that your body may use to support heart health and manage inflammation. It also includes inactive ingredients—gum acacia, pullulan, and rice—which are fillers and binders that help form the capsule.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed

This product doesn't appear to be marketed for a specific use, so we graded Resveratrol's overall clinical evidence instead.

Moderate

Some clinical evidence supports Resveratrol for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Allergic rhinitis (hay fever) — rated "Possibly Effective" (Natural Medicines).
  • On file: Obesity — rated "Possibly Effective" (Natural Medicines).

In the research we hold, resveratrol is rated possibly effective for obesity and allergic rhinitis (hay fever), meaning there's some evidence but it's not conclusive. For cardiovascular disease and high cholesterol, the evidence suggests it's possibly ineffective.

The data doesn't establish clear benefit for other uses.

The evidence, ingredient by ingredient Resveratrol

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Resveratrol from food sources is well tolerated. In higher-dose supplements, the most common side effects are digestive—diarrhea, gastrointestinal discomfort, and loose stools.

Headache, fatigue, memory loss, and a skin rash have been reported rarely; one rash resolved within two weeks of stopping the supplement. High-dose long-term safety isn't fully known.

For pregnancy, the safety data advises against concentrated supplements—there isn't enough information to know either way. For breastfeeding, the data is similarly incomplete, so you'll want to talk with your doctor or pharmacist before use.

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Resveratrol.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 823 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Talk to your pharmacist about resveratrol if you take blood thinners or antiplatelet drugs (Moderate risk of increased bleeding). Also flag any medications metabolized by your liver's CYP2C19, CYP1A2, CYP3A4, or CYP2E1 enzymes (Moderate risk of raised drug levels), especially if you're on a high dose.

The search tool on this page will help you check your specific medications.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

Resveratrol may appeal to you if you're interested in supporting heart health or managing seasonal allergies, but the evidence is modest. If you take blood thinners, any heart medication, or drugs metabolized by your liver, check with your pharmacist first.

Resveratrol5 drug types · 822 drugs

Anticoagulant/Antiplatelet Drugs

Resveratrol may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Resveratrol seems to have antiplatelet effects.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, resveratrol might increase levels of drugs metabolized by CYP1A2.
In vitro research shows that resveratrol can inhibit CYP1A2 enzymes. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, resveratrol might increase levels of drugs metabolized by CYP2C19.
In vitro research shows that resveratrol can inhibit CYP2C19 enzymes. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2E1 (Cyp2E1) Substrates

Resveratrol might increase levels of drugs metabolized by CYP2E1.
In vitro research suggests that resveratrol inhibits CYP2E1 isoenzyme. Also, a pharmacokinetic study shows that taking resveratrol 500 mg daily for 10 days prior to taking a single dose of chlorzoxazone 250 mg increases the maximum concentration of chlorzoxazone by about 54%, the area under the curve of chlorzoxazone by about 72%, and the half-life of chlorzoxazone by about 35%. Chlorzoxazone is used as a probe drug for CYP2E1.

Likelihood Probable Evidence B
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, resveratrol might increase levels of drugs metabolized by CYP3A4.
In vitro research shows that resveratrol can inhibit the CYP3A4 enzyme. However, clinical research shows that taking resveratrol 3000 mg daily for 8 weeks does not necessitate dose adjustments to medications metabolized by CYP3A4.

Organic Resveratrol by Dr. Mercola: Common Questions

Does Organic Resveratrol by Dr. Mercola interact with any medications?
Yes. Based on its ingredients, Organic Resveratrol has a known interaction with 822 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Organic Resveratrol contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is resveratrol safe to take while pregnant or breastfeeding?
The safety data for resveratrol in pregnancy and breastfeeding isn't complete enough to say either way. The facts advise against concentrated supplements during pregnancy and caution against breastfeeding use. Talk with your doctor or pharmacist for personalized advice.
What are the most common side effects?
At higher doses, digestive upset is the main concern—diarrhea, gastrointestinal discomfort, and loose stools. Headache, fatigue, memory loss, and rarely a skin rash have also been reported. At typical supplement doses, it's generally well tolerated.
Does resveratrol actually help with weight loss?
The research rates resveratrol as possibly effective for obesity, meaning there's some evidence but it's not conclusive. It's not a proven weight-loss tool on its own.
Will this help my high cholesterol?
The evidence suggests resveratrol is possibly ineffective for high cholesterol, so it's not established as a useful supplement for that goal. Talk with your doctor about treatments that do have stronger evidence behind them.
What is resveratrol and where does it come from?
Resveratrol is a plant compound found in grape skins, red wine, and other foods. In this supplement, it's extracted and concentrated into capsule form so you're getting a higher dose than you'd get from food alone.
Is this product free of fillers?
No. This supplement contains inactive ingredients—gum acacia, pullulan, and rice—which act as fillers and binders to help hold the capsule together. These are standard in most supplements.
