HelloPharmacist Scorecard of Resveratrol 350 mg by NOW
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
This product contains one active ingredient: trans-resveratrol, a compound derived from Polygonum cuspidatum (Japanese knotweed) extract that's also found naturally in red wine and grapes. The remaining ingredients—hypromellose, magnesium stearate, and silicon dioxide—are inactive excipients that form and stabilize the capsule.
Does it work?
Moderate evidence
The evidence for resveratrol is mixed. It's rated possibly effective for obesity and allergic rhinitis (hay fever), meaning some research supports it but more study is needed.
For cardiovascular disease and high cholesterol, the data we hold rates it possibly ineffective—meaning the current evidence leans toward it not working for those uses. If you're considering this supplement for a specific condition, ask your pharmacist which uses have the strongest backing.
How safe is it?
Well-documented data
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 reported.
A few people in trials have reported headache, fatigue, and a skin rash (which resolved after stopping), but these are rare. Long-term safety at high doses isn't fully known.
For pregnancy and breastfeeding, the safety data advises against concentrated supplements like this one—there isn't enough information to know they're safe. Talk with your doctor or pharmacist for personalized advice if you're pregnant or nursing.
Meds to double-check
Moderate interaction found
Before taking this product, double-check any blood thinners or antiplatelet drugs you're on—resveratrol may increase bleeding risk. Also flag any medications broken down by your liver (CYP2C19, CYP1A2, CYP3A4, or CYP2E1 substrates), as resveratrol could raise their levels.
Use the medication checker on this page to search your drugs.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
Resveratrol may help with weight management or hay fever symptoms, but the evidence is still being built. If you take blood thinners, antiplatelet drugs, or any medication metabolized by your liver, check your exact medications with the tool below before you start.
A quick conversation with your pharmacist is worth the peace of mind.

Resveratrol 350 mg by NOW Drug Interactions
HelloPharmacist Interaction Report
Resveratrol 350 mg by NOW contains one active ingredient—trans-resveratrol—which interacts with several medication types.
The most serious concern is with blood thinners and antiplatelet drugs (such as warfarin, aspirin, and clopidogrel): resveratrol may increase bleeding risk by thinning the blood itself.
Read the full breakdown — every affected drug type, severity by severity
Resveratrol can also theoretically raise levels of drugs broken down by your liver's CYP enzymes (CYP2C19, CYP1A2, CYP3A4, and CYP2E1), which means these medications could build up in your bloodstream. The CYP3A4 interaction is the most studied: a clinical trial at a very high dose (3000 mg daily) showed no dose adjustment was needed, but at the 350 mg dose in this product, the real-world effect remains unclear.
The CYP2E1 interaction has been documented in humans—a study showed resveratrol 500 mg daily increased blood levels of chlorzoxazone by about 54%.
These interactions are listed as Moderate in severity. Altogether, these interactions span 812 individual medications.

Polygonum cuspidatum extract
Anticoagulant/Antiplatelet Drugs
Theoretically, hu zhang might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
Hu zhang contains the constituent resveratrol. Resveratrol seems to have antiplatelet effects.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, hu zhang might increase levels of drugs metabolized by CYP1A2.
Hu zhang contains the constituent resveratrol. In vitro research shows that resveratrol might inhibit the CYP1A2 enzyme. This interaction has not been reported in humans.
Cytochrome P450 2C19 (Cyp2C19) Substrates
Theoretically, hu zhang might increase levels of drugs metabolized by CYP2C19.
Hu zhang contains the constituent resveratrol. In vitro research shows that resveratrol might inhibit the CYP2C19 enzyme. This interaction has not been reported in humans.
Cytochrome P450 2E1 (Cyp2E1) Substrates
Theoretically, hu zhang might increase levels of drugs metabolized by CYP2E1.
Hu zhang contains the constituent resveratrol. In vitro research shows that resveratrol might inhibit the CYP2E1 enzyme. 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.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, hu zhang might increase levels of drugs metabolized by CYP3A4.
Hu zhang contains the constituent resveratrol. In vitro research shows that resveratrol might inhibit the CYP3A4 enzyme. However, a clinical study in adults with NAFLD found that adding resveratrol 3000 mg daily for 8 weeks did not necessitate dose adjustments to any established medications metabolized by CYP3A4.
Estrogens
Theoretically, hu zhang might competitively inhibit the effects of estrogen replacement therapy.
In vitro research shows that hu zhang might have estrogenic activity.
Carbamazepine (Tegretol)
Theoretically, hu zhang might increase the effects and adverse effects of carbamazepine.
In animals, blood and tissue levels of carbamazepine were increased when given in combination with hu zhang. It is thought that increased levels of carbamazepine are due to cytochrome P450 3A4 (CYP3A4) inhibition. This interaction has not been reported in humans.
