HelloPharmacist Scorecard of Maximum Strength Resveratrol 250 mg by TRUNATURE

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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

TRUNATURE Maximum Strength Resveratrol contains 2 active ingredients: resveratrol and red wine extract. Both supply resveratrol, a naturally occurring compound found in red grapes and wine.

The product also includes inactive ingredients such as soybean oil, purified water, and glycerin to form the softgel capsule.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Resveratrol's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: antioxidant protection against free radicals.
  • We looked for evidence on: Cardiovascular disease (CVD), Hypercholesterolemia, Hypertension, Metabolic syndrome, Diabetes, Aging skin — 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, Metabolic syndrome.
  • Also on file: Resveratrol is rated "Insufficient Reliable Evidence To Rate" for Age-related cognitive decline, Aging skin, Diabetes, Hypertension.

The evidence on resveratrol for your goals is mixed. It's rated possibly effective for obesity and for allergic rhinitis (hay fever), meaning some studies suggest benefit but the data isn't conclusive.

For cardiovascular disease and high cholesterol, the data leans toward possibly ineffective — so while resveratrol is marketed for heart health, current evidence doesn't strongly back those claims.

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.

At typical supplement doses, resveratrol is generally well tolerated. At higher doses, the most common side effects are digestive — diarrhea, stomach discomfort, and loose stools.

A few isolated cases have reported headache, fatigue, memory loss (in patients on dialysis, where the connection isn't clear), and a skin rash that went away after stopping the product. There isn't enough safety data to know whether this product is safe during pregnancy or while breastfeeding; the safety notes advise caution and suggest talking with your doctor or pharmacist before use if you're pregnant or nursing.

Long-term safety at high doses isn't fully known.

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, check with your doctor or pharmacist if you take blood thinners or antiplatelet drugs (such as warfarin, aspirin, or clopidogrel) — resveratrol may increase bleeding risk. Also double-check any medications broken down by your liver, especially those metabolized by the CYP2C19, CYP1A2, CYP2E1, or CYP3A4 enzyme systems, as resveratrol may raise their blood levels.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Resveratrol may help with obesity and hay fever, though the evidence is tentative, and it doesn't appear effective for heart health or cholesterol. The main caution is if you take blood thinners or drugs processed by certain liver enzymes — check your medications against the tool on this page.

At typical doses it's well tolerated, but higher doses can cause digestive upset. Talk with your doctor or pharmacist before starting, especially if you're pregnant, nursing, or on any medications.

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.

Maximum Strength Resveratrol 250 mg by TRUNATURE: Common Questions

Does Maximum Strength Resveratrol 250 mg by TRUNATURE interact with any medications?
Yes. Based on its ingredients, Maximum Strength Resveratrol 250 mg 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?
Maximum Strength Resveratrol 250 mg 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's resveratrol and where does it come from?
Resveratrol is a compound naturally found in red grapes and red wine. This product delivers it via pure resveratrol and red wine extract, giving you a concentrated dose of what you'd get from food sources.
Can I take this if I'm pregnant or breastfeeding?
There isn't enough safety data to know either way. The safety information advises against using concentrated resveratrol supplements during pregnancy and breastfeeding. Talk with your doctor or pharmacist before taking it if you're pregnant or nursing — they can weigh the risks and benefits for your situation.
Will this help my cholesterol or heart health?
The evidence doesn't strongly support it. Resveratrol is rated possibly ineffective for both high cholesterol and cardiovascular disease in the data we have, so while it's marketed for those purposes, research hasn't backed those claims yet.
What are the most common side effects?
At higher doses, the most common side effects are digestive — diarrhea, stomach discomfort, and loose stools. At typical supplement doses, it's generally well tolerated. A very small number of people have reported headache, fatigue, or a skin rash, but these are rare.
How much should I take, and is it safe long-term?
The product facts don't specify a recommended dose or duration. Talk with your doctor or pharmacist about the right amount for you. Long-term safety at high doses isn't fully known, so they can also advise on how long it's safe to use.
