HelloPharmacist Scorecard of Resveratrol 1000 mg by Oomph Naturals

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.

This product contains one active ingredient: hu zhang (Polygonum cuspidatum) rhizome and root extract, standardized to deliver 1000 mg of resveratrol per capsule. Resveratrol is a compound from the hu zhang plant that's been used in traditional medicine.

The capsules also contain gelatin and rice powder as inactive ingredients to hold and form the product.

Does it work?

Couldn't assess
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 assessable

This is a single-ingredient Hu Zhang product and its label doesn't state a use — see Hu Zhang's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence we hold rates hu zhang for several conditions — hepatitis, rheumatoid arthritis, wound healing, gout, osteoarthritis, and unstable angina — as having insufficient reliable evidence. This means published studies haven't yet established whether it works for these uses.

We can't tell you whether this product will be effective for any specific condition based on the data available to us.

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 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.

Human safety data for hu zhang supplements are limited. The emodin compound it contains may cause digestive upset in some people.

The product safety notes advise against it in pregnancy due to insufficient safety data and concerns that some of its compounds might affect the uterus. It's also not recommended while breastfeeding because there isn't enough safety information.

If you're pregnant, planning to become pregnant, or breastfeeding, talk with your pharmacist or doctor before using this product.

Side effects, ingredient by ingredient Hu Zhang

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 — Hu Zhang.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 827 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, double-check any blood thinners or antiplatelet drugs you're on — hu zhang may increase bleeding risk. Also screen drugs metabolized by CYP1A2, CYP2C19, CYP3A4, and CYP2E1 liver enzymes, estrogen replacement therapy, and carbamazepine.

Polygonum cuspidatum Rhizome, Root Extract7 drug types · 826 drugs

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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
Estrogens

Theoretically, hu zhang might competitively inhibit the effects of estrogen replacement therapy.
In vitro research shows that hu zhang might have estrogenic activity.

Likelihood Possible Evidence D
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.

Resveratrol 1000 mg by Oomph Naturals: Common Questions

Does Resveratrol 1000 mg by Oomph Naturals interact with any medications?
Yes. Based on its ingredients, Resveratrol 1000 mg has a known interaction with 826 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Resveratrol 1000 mg 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.
Does resveratrol actually work for arthritis or other joint problems?
The evidence we have rates resveratrol for both rheumatoid arthritis and osteoarthritis as insufficient to tell you whether it works. More research is needed before we can say either way.
Can I take this while I'm on a blood thinner like warfarin?
Don't take this without checking first. Hu zhang may increase the risk of bleeding when combined with blood thinners or antiplatelet drugs — your pharmacist or doctor needs to know about both so they can monitor you or adjust your plan.
Will this interact with my liver medications?
Possibly. Hu zhang can theoretically increase levels of drugs your liver breaks down through several enzyme systems (CYP1A2, CYP2C19, CYP3A4, and CYP2E1). Use the medication checker below with your exact drugs to be sure.
Can I take this if I'm on estrogen or hormone replacement therapy?
Theoretically, hu zhang might block some of estrogen's effects. Talk with your pharmacist before adding this to hormone therapy so you can make sure your current dose still works the way you need it to.
Is this safe to use while breastfeeding?
No. There isn't enough safety information to recommend hu zhang while breastfeeding. Talk with your doctor about alternatives if you're looking for a supplement during this time.
What's in this besides the resveratrol?
The active ingredient is hu zhang extract providing 1000 mg of resveratrol per capsule. The capsule itself is made from gelatin and rice powder — that's it.
