HelloPharmacist Scorecard of Premier Resveratrol by Premier Research Labs

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.

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.

Premier Resveratrol is a single-ingredient liquid supplement containing resveratrol — a polyphenol found naturally in red grape skins, berries, and other plants. The liquid is made with purified water, organic cane alcohol, and organic molasses as inactive ingredients.

Does it work?

Leans against
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: antioxidant, cardiovascular, immune and cognitive support.
  • We looked for evidence on: Cardiovascular disease (CVD), Hypercholesterolemia, Hypertension, Age-related cognitive decline, Cognitive function, Cognitive impairment — and 4 related terms.
  • 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.
  • Also on file: Resveratrol is rated "Insufficient Reliable Evidence To Rate" for Age-related cognitive decline, Alzheimer disease, Cognitive function, Cognitive impairment, and more.

The evidence for resveratrol is mixed. It's possibly effective for obesity and allergic rhinitis (hay fever), meaning some research supports benefit but the evidence isn't conclusive.

For cardiovascular disease and high cholesterol, the available data suggests it's possibly ineffective — so don't count on it for those purposes.

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 oral supplement form at higher doses, the most common side effects are digestive — diarrhea, loose stools, and gastrointestinal discomfort.

Occasional headache and fatigue have been reported. Long-term safety at high doses isn't fully known, so stick to typical supplement doses.

There isn't enough safety information to recommend concentrated resveratrol supplements during pregnancy or while breastfeeding. If you're pregnant or nursing, 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 Premier Resveratrol, double-check with your pharmacist or doctor if you take blood thinners or antiplatelet drugs (aspirin, warfarin, clopidogrel) — resveratrol may increase bleeding risk. Also flag any medications processed by your liver's CYP enzymes, especially those that are dose-sensitive, since resveratrol can theoretically raise drug levels.

Use the medication checker below with your specific prescriptions.

The bottom line

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

Premier Resveratrol may be worth considering if you're interested in possibly supporting weight management or seasonal allergies — though the evidence is modest. However, if you take blood thinners, antiplatelet drugs, or medications metabolized by liver enzymes, you need to check with your doctor or pharmacist before starting it.

Digestive upset is the most likely side effect at higher doses.

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.

Yes. Based on its ingredients, Premier 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?

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.
Will resveratrol help with weight or hay fever?

What side effects should I watch for?
The most common are digestive — diarrhea, loose stools, and stomach discomfort — especially at higher doses. Occasional headache and fatigue have been reported. Most people tolerate it well at typical supplement doses.
Is it safe to take while pregnant or breastfeeding?
There isn't enough safety information about concentrated resveratrol supplements in pregnancy or while breastfeeding. Talk with your doctor or pharmacist before using this product if you're pregnant, planning to become pregnant, or nursing.
Why are there so many medication interactions listed?

Does resveratrol help with cholesterol or heart disease?
The available evidence suggests it's possibly ineffective for high cholesterol and cardiovascular disease. If heart health is your goal, focus on treatments your doctor has recommended.
What's in this liquid besides resveratrol?
It's made with purified water, organic cane alcohol as the carrier, and organic molasses — all inactive ingredients to deliver the resveratrol.
