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 3 of its 3 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Transmax has three active ingredients. Piperine is an extract from black pepper that's traditionally used to enhance absorption of other nutrients.

Trans-resveratrol and polydatin are both derived from Polygonum cuspidatum (hu zhang) root, a plant used in traditional Chinese medicine. The capsule contains no other inactive ingredients listed.

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.

Why this rating?
  • The label markets this product for: antiaging and disease prevention support.
  • We looked for evidence on: Obesity, Diabetes, Age-related disease, Mitochondrial function.
  • The closest evidence on file: Black Pepper is rated "Insufficient Reliable Evidence To Rate" for Obesity (Natural Medicines).
  • Also on file: Hu Zhang is rated "Insufficient Reliable Evidence To Rate" for Diabetes.

The evidence for what Transmax is meant to do isn't established in the data we hold. Piperine has insufficient reliable evidence for hay fever, asthma, athletic performance, headache, depression, and diarrhea.

The resveratrol and polydatin extracts also have insufficient reliable evidence for hepatitis, rheumatoid arthritis, wound healing, gout, osteoarthritis, and unstable angina. If you're thinking about this product for a specific condition, talk it over with your doctor or pharmacist about what the research actually supports.

The evidence, ingredient by ingredient Black Pepper Hu Zhang

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 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Piperine from food amounts is generally well tolerated, though concentrated supplements should be used more cautiously and only under medical advice. The most common side effects are a burning aftertaste, upset stomach, and reduced taste perception; rarely, allergic reactions can occur.

The resveratrol and polydatin extracts have limited human safety data. Because of concerns about their effects on the uterus and bowel and insufficient safety information, they're best avoided during pregnancy and breastfeeding.

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?
  • 2 of the 2 matched ingredients can interact with medications — Black Pepper, Hu Zhang.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; lithium.
  • For scale: 1,037 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 Transmax, double-check with your doctor or pharmacist if you take seizure medications (especially phenytoin), heart or blood pressure drugs (like propranolol), blood thinners or antiplatelet drugs (like warfarin or aspirin), HIV antiretrovirals, tuberculosis antibiotics, asthma or COPD medications (like theophylline), cholesterol drugs, immunosuppressants, nerve pain or seizure medication (like carbamazepine), or any drug that's processed through your liver's CYP1A2, CYP2C19, CYP2E1, or CYP3A4 pathways. Estrogen replacement therapy may also be affected.

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.

This product carries real interaction risks, especially with seizure medications, heart drugs, blood thinners, and many others processed through your liver. If you take any prescription medications—particularly phenytoin, propranolol, estrogen, anticoagulants, or drugs metabolized by the CYP3A4 enzyme—check with your doctor or pharmacist before starting Transmax.

The evidence for what it's supposed to do isn't solid, so weigh that against the interaction potential.

Piperine17 drug types · 1,019 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, black pepper might increase the risk of bleeding when taken with antiplatelet or anticoagulant drugs.
In vitro research shows that piperine, a constituent of black pepper, seems to inhibit platelet aggregation. This has not been reported in humans.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, black pepper might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research shows that piperine, a constituent of black pepper, can reduce blood glucose levels. Monitor blood glucose levels closely. Dose adjustments might be necessary.

Likelihood Possible Evidence D
Atorvastatin (Lipitor)

Theoretically, black pepper might increase blood levels of atorvastatin.
Animal research shows that taking piperine, a constituent of black pepper, 35 mg/kg can increase the maximum serum concentration of atorvastatin three-fold. This has not been reported in humans.

Likelihood Possible Evidence D
Cyclosporine (Neoral, Sandimmune)

Theoretically, black pepper might increase the effects and side effects of cyclosporine.
In vitro research shows that piperine, a constituent of black pepper, increases the bioavailability of cyclosporine. This has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, black pepper might increase levels of drugs metabolized by CYP2D6.
In vitro research suggests that some constituents of black pepper inhibit CYP2D6. This has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, black pepper might increase levels of drugs metabolized by CYP3A4.
In vitro research and pharmacokinetic simulation data suggest that piperine, a constituent of black pepper, as well as the pepper fruit seem to inhibit CYP3A4. This has not been reported in humans.

Likelihood Possible Evidence D
Lithium

Theoretically, black pepper might increase blood levels of lithium due to its diuretic effects. The dose of lithium might need to be reduced.
Black pepper is thought to have diuretic properties.

Likelihood Probable Evidence D
Nevirapine (Viramune)

Black pepper might increase blood levels of nevirapine.
Clinical research shows that piperine, a constituent of black pepper, increases the plasma concentration of nevirapine. However, no adverse effects were observed in this study.

Likelihood Probable Evidence D
P-Glycoprotein Substrates

Theoretically, black pepper might increase levels of P-glycoprotein substrates.
In vitro research shows that piperine, a constituent of black pepper, seems to inhibit P-glycoprotein.

Likelihood Possible Evidence D
Pentobarbital (Nembutal)

Theoretically, black pepper might increase the sedative effects of pentobarbital.
Animal research shows that piperine, a constituent of black pepper, increases pentobarbital-induced sleeping time.

Likelihood Possible Evidence D
Phenytoin (Dilantin)

Black pepper might increase blood levels of phenytoin.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption, slow elimination, and increase levels of phenytoin. Taking a single dose of black pepper 1 gram along with phenytoin seems to double the serum concentration of phenytoin. Consuming a soup with black pepper providing piperine 44 mg/200 mL of soup along with phenytoin also seems to increase phenytoin levels when compared with consuming the same soup without black pepper.

Likelihood Possible Evidence B
Propranolol (Inderal)

Black pepper might increase blood levels of propranolol.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption and slow elimination of propranolol.

Likelihood Possible Evidence B
Rifampin (Rifadin)

Black pepper might increase blood levels of rifampin.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption and serum levels of rifampin.

Likelihood Possible Evidence B
Theophylline

Black pepper might increase blood levels of theophylline.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption and slow elimination of theophylline.

Likelihood Possible Evidence D
Amoxicillin (Amoxil, Trimox)

Theoretically, black pepper might increase the effects and side effects of amoxicillin.
Animal research shows that taking piperine, a constituent of black pepper, with amoxicillin increases plasma levels of amoxicillin. This has not been reported in humans.

Likelihood Possible Evidence D
Carbamazepine (Tegretol)

Theoretically, black pepper might increase blood levels of carbamazepine, potentially increasing the effects and side effects of carbamazepine.
One clinical study in patients taking carbamazepine 300 mg or 500 mg twice daily shows that taking a single 20 mg dose of purified piperine, a constituent of black pepper, increases carbamazepine levels. Piperine may increase carbamazepine absorption by increasing blood flow to the GI tract, increasing the surface area of the small intestine, or inhibiting cytochrome P450 3A4 (CYP3A4) in the gut wall. Absorption was significantly increased by 7-10 mcg/mL/hour. The time to eliminate carbamazepine was also increased by 4-8 hours. Although carbamazepine levels were increased, this did not appear to increase side effects. In vitro research also shows that piperine can increase carbamazepine levels by 11% in a time-dependent manner.

Likelihood Possible Evidence B
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, black pepper might decrease levels and clinical effects of drugs metabolized by CYP1A2.
In vitro research suggests that black pepper induces CYP1A2. This 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.

Transmax by Biotivia: Common Questions

Does Transmax by Biotivia interact with any medications?
Yes. Based on its ingredients, Transmax has a known interaction with 1,036 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Transmax contains 3 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.
Is it safe to take Transmax while pregnant?
Piperine is likely safe in pregnancy. However, the resveratrol and polydatin extracts don't have enough safety data, and some compounds they contain may affect the uterus, so pregnancy use isn't recommended for those. Talk with your doctor or pharmacist about whether this product is right for you during pregnancy.
Is it safe to take Transmax while breastfeeding?
Piperine is likely safe while breastfeeding. The resveratrol and polydatin extracts have insufficient safety information, so they should be avoided while nursing. If you're considering this product, check with your doctor or pharmacist first.
What side effects might I notice?
Most commonly, you might experience a burning aftertaste, upset stomach, or reduced taste perception. Rarely, an allergic reaction is possible. The product is generally well tolerated when used as directed, though concentrated supplements warrant more caution.
Does piperine really help other supplements work better?
Piperine is included because it may help your body absorb other nutrients better. The evidence for this product's specific uses—like hay fever, asthma, or joint health—is insufficient, so we can't say whether it works for those purposes.
What's hu zhang, and why is it in here?
Hu zhang is Polygonum cuspidatum root, a plant used in traditional Chinese medicine. This product includes two extracts from it—trans-resveratrol and polydatin. They're included for their antioxidant properties, though evidence for treating specific conditions is insufficient.
Can I take this with my other supplements or vitamins?
That depends on what they contain and how they're processed. Use the medication checker on this page with all your supplements and prescriptions, or ask your pharmacist to review them together.
