HelloPharmacist Scorecard of Resveratrol by aSquared Nutrition

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

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 powder. Resveratrol is a plant compound found naturally in foods like red grapes, berries, and peanuts — it's been studied for its potential effects on metabolism, inflammation, and heart health.

The capsule also contains two inactive ingredients — methylcellulose (the capsule material itself) and rice flour (a filler).

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).

The evidence on resveratrol is mixed. It shows possibly effective for obesity and allergic rhinitis (hay fever), meaning some clinical data support its use, though more research is needed.

For cardiovascular disease and high cholesterol, the evidence rates as possibly ineffective, so it's not a reliable choice for those conditions based on current data.

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 is generally well tolerated at typical supplement doses. At higher doses, digestive upset — diarrhea, gastrointestinal discomfort, and loose stools — is the main concern.

Long-term safety at high doses isn't fully established, so you shouldn't expect to know the full picture of effects over years. The safety data advises against concentrated resveratrol supplements during pregnancy and while breastfeeding because there isn't enough information to know it's safe.

Rarely, headache, fatigue, or memory loss has been reported in patients on dialysis, and isolated cases of skin rash or allergic reactions have occurred.

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 you start, check with your doctor or pharmacist if you take blood thinners (anticoagulants) or antiplatelet drugs — resveratrol may increase bleeding risk. Also flag any medications broken down by CYP2E1, CYP1A2, CYP2C19, or CYP3A4 enzymes, which resveratrol can theoretically raise to higher levels.

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 be worth considering if you're exploring support for weight management or hay fever, though the evidence is modest. If you take blood thinners, drugs metabolized by CYP2E1, CYP1A2, CYP2C19, or CYP3A4, or if you're pregnant or breastfeeding, talk with your doctor or pharmacist before starting it.

Check your exact medications with the tool on this page to see if resveratrol is right for you.

Resveratrol, Powder5 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.

Resveratrol by aSquared Nutrition: Common Questions

Does Resveratrol by aSquared Nutrition interact with any medications?
Yes. Based on its ingredients, 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?
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.
Can I take resveratrol if I'm on a blood thinner like warfarin?
Not without checking first. Resveratrol may increase bleeding risk when combined with anticoagulants or antiplatelet drugs. Talk to your doctor or pharmacist before adding it — they'll know your full medication picture and can advise whether it's safe for you.
Will resveratrol help me lose weight?
The evidence suggests it's possibly effective for obesity, meaning some clinical data support it, though more research is needed. It's not a proven weight-loss tool on its own — it works best alongside diet and exercise, and real results vary person to person.
Is it safe to take resveratrol while pregnant or breastfeeding?
There isn't enough safety information to know either way. The data advises against concentrated supplements during pregnancy and while breastfeeding. Talk with your doctor or pharmacist about whether resveratrol is right for you in these situations.
What are the side effects of resveratrol?
At typical doses, it's well tolerated. At higher doses, diarrhea, gastrointestinal discomfort, and loose stools are the main concerns. Rarely, headache, fatigue, rash, or allergic reactions have been reported.
Can resveratrol help my cholesterol or heart disease?
The evidence doesn't support it. For cardiovascular disease and high cholesterol, resveratrol rates as possibly ineffective, so it's not a reliable choice based on current data.
Does this product have any fillers or other ingredients?
The capsule itself is made of methylcellulose, and rice flour is added as a filler. The active ingredient is resveratrol powder only.
