HelloPharmacist Scorecard of Resveratrol Plus+ by Member's Mark

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

What’s inside

Partial disclosure
Ingredient Transparency · database check
Partial

Most active ingredients list an amount, but at least one is hidden in a blend or missing.

Why this rating?
  • The label discloses an exact amount for 2 of its 3 active ingredients.
  • “Resveratrol Complex” is a proprietary blend — the label gives one combined amount (300 mg) without saying how much of each component you get.

Member's Mark Resveratrol Plus+ contains three active ingredients: trans-resveratrol, trans-pterostilbene, and a resveratrol complex with various glycosides. Trans-resveratrol is a naturally occurring polyphenol found in grapes and red wine; the other ingredients are related compounds thought to support similar functions in your body.

The product also contains several inactive ingredients—gelatin (capsule shell), rice concentrate, magnesium stearate, silica, titanium dioxide, and colorants (FD&C Red #3 and FD&C Blue #1)—to hold the capsule together and keep it stable on the shelf.

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
Leans against

The strongest graded evidence we hold for the stated purpose leans against a benefit.

Why this rating?
  • The label markets this product for: Supports heart health and cardiovascular antioxidant protection.
  • We looked for evidence on: Cardiovascular disease (CVD), Hypercholesterolemia, Hypertension, Metabolic syndrome, Coronary artery disease, Atherosclerosis.
  • The closest evidence on file: Resveratrol is rated "Possibly Ineffective" for Cardiovascular disease (CVD) (Natural Medicines).
  • Also on file: Resveratrol is rated "Possibly Ineffective" for Hypercholesterolemia, Metabolic syndrome.
  • Also on file: Resveratrol is rated "Insufficient Reliable Evidence To Rate" for Hypertension.

For obesity and allergic rhinitis (hay fever), trans-resveratrol is rated possibly effective based on available evidence. For cardiovascular disease and high cholesterol, the evidence currently suggests it is possibly ineffective.

We do not hold effectiveness data for trans-pterostilbene or the glycoside blend in isolation, so those components' benefits are not established in our records.

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.

Trans-resveratrol is generally well tolerated at typical supplement doses. At higher doses, it can cause digestive upset—diarrhea, gastrointestinal discomfort, and loose stools are the most common side effects.

There are isolated reports of headache, fatigue, memory loss, and skin rash in clinical use, though causality hasn't been confirmed. Long-term safety at high doses isn't fully known.

The safety data advises against use during pregnancy and breastfeeding because there isn't enough information to confirm it's safe in those situations. If you're pregnant, planning to become pregnant, or breastfeeding, talk with your doctor or pharmacist before taking this product.

Side effects, ingredient by ingredient Resveratrol

Meds to double-check

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.

Before taking this product, double-check with your doctor or pharmacist if you take blood thinners or antiplatelet drugs (like warfarin, aspirin, or clopidogrel)—resveratrol may increase bleeding risk. Also confirm if you take medications broken down by your liver's CYP2C19, CYP1A2, CYP3A4, or CYP2E1 enzymes, as resveratrol may raise their levels in your blood.

Muscle relaxants like chlorzoxazone showed a significant increase in blood levels in one study.

The bottom line

Scorecard at a glancePartially disclosed formula with graded evidence leaning against its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Resveratrol Plus+ may help with obesity and allergic rhinitis, but evidence is limited. The main concern is interaction with blood thinners and drugs metabolized by certain liver enzymes—especially if you take high doses.

If you're on any prescription medications, particularly anticoagulants or muscle relaxants, confirm with your doctor or pharmacist before starting this supplement. Pregnant and breastfeeding people should also check with their healthcare provider first.

Why is this formula superior? The amount of active trans-resveratrol is key.

Formulation

Supports heart health Cardiovascular/antioxidant The secret of red wine for total heart health

Member's Mark Resveratol Plus+ has been formulated to promote cardiovascular health and to provide superior antioxidant protection. Made famous by the studies on red wine, Resveratrol has been discovered to be of important benefit to your health.

This product is not derived from, nor does it contain, red wine.

Formula

Provides 100 mg trans-resveratrol With active form of trans-resveratrol With pterostilbene for superior antioxidant protection

1 capsule = 100 glasses of red wine (resveratrol content) and 200 blueberries (pterostilbene content)

Ours: contains a clinical dose, 100 mg of active trans-resveratrol. Others: typically contain low or trace amounts and often do not specifically state the amount of active trans-resveratrol. Our formula contains Pterostilbene, an antioxidant naturally found in blueberries. Pterostilbene has been shown in laboratory tests to work synergistically with trans-resveratrol to provide enhanced antioxidant properties for anti-aging benefits.

Member's Mark Resveratol Plus+ contains Polygonum cuspidatum and Vitis vinifera, in order to provide you with the benefits of Resveratrol in a small, concentrated dosage.

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.

Does Resveratrol Plus+ by Member's Mark interact with any medications?
Yes. Based on its ingredients, Resveratrol Plus+ 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?
Resveratrol Plus+ contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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.
What does trans-resveratrol do?
Trans-resveratrol is a compound found naturally in grapes and red wine. In this product, it's included because evidence suggests it may help with weight management and allergic rhinitis (hay fever), though the evidence is still limited. It does not appear to help with heart disease or high cholesterol based on current research.
Will this product make me bleed if I'm on a blood thinner?
Resveratrol may have antiplatelet effects and could increase bleeding risk if combined with blood thinners like warfarin, aspirin, or clopidogrel. This is a moderate-severity concern, so you need to check with your doctor or pharmacist before starting it if you take any of these medications.
What are the most common side effects?
At higher doses, diarrhea, gastrointestinal discomfort, and loose stools are the most common side effects. At typical supplement doses, resveratrol is generally well tolerated. Long-term safety at high doses isn't fully known.
Is it safe to take during pregnancy or breastfeeding?
There isn't enough safety information to know whether concentrated supplements like this are safe during pregnancy or breastfeeding. Talk with your doctor or pharmacist for personalized advice if you're pregnant, planning to become pregnant, or breastfeeding.
Does this product interact with liver enzyme medications?
Yes—resveratrol can theoretically increase blood levels of drugs broken down by your liver's CYP enzymes, particularly CYP2C19, CYP1A2, CYP3A4, and CYP2E1. One study showed a 54% increase in a muscle relaxant's level. Check your medications with your doctor or pharmacist before starting.
