HelloPharmacist Scorecard of Pterostilbene & Resveratrol 50 mg / 250 mg by Protocol For Life Balance
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 2 active ingredients: 50 mg of trans-pterostilbene and 250 mg of Polygonum cuspidatum extract (hu zhang). Hu zhang is a plant extract used in traditional medicine; it's a natural source of resveratrol, a polyphenol compound.
The capsule also contains inactive ingredients—cellulose, cellulose powder, stearic acid, and silica—which are fillers and binders.
Does it work?
Not established
The evidence we hold on hu zhang for treating hepatitis, rheumatoid arthritis, wound healing, gout, osteoarthritis, or unstable angina is insufficient to rate—meaning human studies haven't established it works for those uses. We have no effectiveness data on file for trans-pterostilbene.
If you're considering this product for a specific health goal, talk with your doctor or pharmacist about whether the science supports it.
How safe is it?
Some data gaps
Hu zhang is traditionally used in herbal medicine, but human safety data for supplements are limited. The extract contains emodin, a compound that may upset your digestion.
The safety information is insufficient, and some compounds in hu zhang may affect the uterus, so it's best avoided during pregnancy. There's also not enough safety data to recommend use while breastfeeding—talk with your doctor or pharmacist for personalized advice if you're pregnant, planning pregnancy, or nursing.
Meds to double-check
Moderate interaction found
Double-check before starting if you take blood thinners or antiplatelet drugs (warfarin, aspirin, clopidogrel)—there's a Moderate-severity risk of increased bleeding. Also flag any drug metabolized by CYP3A4, CYP2C19, CYP1A2, or CYP2E1 enzymes, estrogen replacement therapy, or carbamazepine (Tegretol), since the hu zhang in this product may theoretically alter how your liver processes them.
Use the medication checker on this page to search your exact prescriptions.
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 some safety-information gaps remain.
This product combines two compounds from plant sources, but human evidence that either one works for common health conditions is lacking. The main safety concern is its potential to thin your blood or interact with your liver's ability to clear certain medications.
If you take a blood thinner, hormone therapy, seizure medication, or any drug metabolized by your liver, check with your doctor or pharmacist before adding this to your routine.

HOW IT WORKS: Like Resveratrol, Pterostilbene belongs to a class of polyphenols called stilbenes that are naturally produced by plants in response to stress. Although these two stilbenes have similar properties, Pterostilbene's methyoxylated structure allows for enhanced absorption and metabolic stability.* Emerging research suggests that Pterostilbene may support cardiovascular health, may help to maintain proper cell cycle regulation, and can promote a healthy response to cellular stress.*

Pterostilbene & Resveratrol 50 mg / 250 mg by Protocol For Life Balance Drug Interactions
HelloPharmacist Interaction Report
Pterostilbene & Resveratrol by Protocol For Life Balance does interact with medications, through its Polygonum cuspidatum extract (hu zhang) content.
The extract contains resveratrol, which in laboratory studies appears to inhibit several liver enzymes that break down drugs. The most serious documented concern is a Moderate-severity risk of increased bleeding when combined with blood thinners or antiplatelet drugs (like warfarin or aspirin), since resveratrol has antiplatelet effects.
Read the full breakdown — every affected drug type, severity by severity
Beyond bleeding risk, the resveratrol in hu zhang may theoretically raise blood levels of drugs metabolized by several liver enzymes: CYP3A4, CYP2C19, CYP1A2, and CYP2E1 substrates. These interactions are based on lab findings; human cases haven't been reported yet.
There's also a Moderate-severity theoretical concern that hu zhang might interfere with estrogen replacement therapy by competing with estrogen's effects. Finally, there's a Minor-severity note about carbamazepine (Tegretol), an anti-seizure medication—animal studies suggest hu zhang could raise its levels, though this hasn't been seen in humans.
We could not check trans-pterostilbene, the product's other active ingredient, because we hold no data for it. Altogether, these interactions span 827 individual medications.

For each ingredient in Pterostilbene & Resveratrol 50 mg / 250 mg with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
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.
