HelloPharmacist Scorecard of Kidney/Urinary Tract by ProEnzol

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

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 2 of its 6 active ingredients.
  • “Synergistic Herbal Blend” is a proprietary blend — the label gives one combined amount (380 mg) without saying how much of each component you get.

ProEnzol contains six active ingredients. Uva ursi leaf extract, dandelion root extract, and parsley are herbal ingredients traditionally used for urinary tract support.

Vitamin A is a fat-soluble nutrient. pHysioProtease is a proteolytic enzyme (a protein-digesting enzyme), and corn silk extract rounds out the blend. Two inactive ingredients—plant fiber and water—serve as fillers and binders.

The product also contains a synergistic herbal blend, meaning some ingredients are formulated together for combined effect; those component herbs are listed individually in the ingredient list above.

Does it work?

Evidence for Intended Use · database check

Leans against

The strongest graded evidence we hold for the stated purpose leans against a benefit.

Why this rating?
  • The label markets this product for: support healthy kidney and urinary tract function.
  • We looked for evidence on: Kidney stones (nephrolithiasis), Benign prostatic hyperplasia (BPH), Prostatitis, urinary tract infection, urinary discomfort, bladder health.
  • The closest evidence on file: Uva Ursi is rated "Possibly Ineffective" for Urinary tract infections (UTIs) (Natural Medicines).
  • Also on file: Corn Silk is rated "Insufficient Reliable Evidence To Rate" for Kidney stones (nephrolithiasis), Prostatitis, Urinary tract infections (UTIs).
  • Also on file: Uva Ursi is rated "Insufficient Reliable Evidence To Rate" for Benign prostatic hyperplasia (BPH).

The evidence supporting this product's ingredients is sparse. Uva ursi for urinary tract infections is rated possibly ineffective in our data, and its use for other conditions like bronchitis lacks reliable evidence.

Dandelion root, parsley, and corn silk extract all show insufficient evidence for the conditions listed—joint pain, tonsillitis, and various other uses. Vitamin A is effective for vitamin A deficiency and possibly effective for oral leukoplakia, aging skin, measles, and ulcerative colitis, though those aren't the focus of a kidney/urinary tract product.

We hold no effectiveness ratings for pHysioProtease in our data.

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 6 of the 6 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 6 of 6.
  • General safety write-ups exist for 6 of 6.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Uva ursi is generally well tolerated at low doses for short-term use, but it can be toxic at high doses or with prolonged use; diarrhea, nausea, stomach upset, and vomiting are common at standard doses, and very high doses (30 grams or more) have been reported to be fatal. Dandelion is generally well tolerated as food but may cause diarrhea, heartburn, and stomach discomfort at supplement strength; allergic reactions including anaphylaxis are rare but possible.

Parsley at normal food amounts is safe, but concentrated extracts and large doses can cause serious effects at very high intakes. Vitamin A is well tolerated at recommended doses but accumulates in your body and can become toxic, especially from high-dose supplements; the most serious risks are with very high intakes.

Corn silk seems to cause few adverse effects, though hypokalemia (low potassium) has been reported with prolonged use. pHysioProtease (protease enzyme) is generally well tolerated but rarely may trigger allergic reactions or digestive upset.

Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 5 of the 6 matched ingredients can interact with medications — Corn Silk, Uva Ursi, Dandelion, Parsley, Vitamin A.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium.
  • For scale: 1,285 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.

Check before taking this product if you use retinoids (like tretinoin or isotretinoin for acne), blood thinners (anticoagulants or antiplatelet drugs, especially warfarin), diabetes medications, blood pressure drugs, mood stabilizers (particularly lithium), diuretics (water pills), corticosteroids, tetracycline antibiotics, fluoroquinolone antibiotics, or any other medication your liver processes heavily—the ingredients here may slow that clearance. No interactions are documented for pHysioProtease, the protease enzyme in this formula, because we hold no interaction data for it.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with graded evidence leaning against its stated purpose. Major medication interactions have been identified, and safety information is well characterized.

This product may appeal to someone looking for herbal support for urinary tract health, but evidence for most of its ingredients is limited. If you're on any prescription medications—especially blood thinners, diabetes drugs, blood pressure medication, lithium, or retinoid acne treatments—you need to check with your doctor or pharmacist before taking it.

Even then, short-term use at the recommended dose is the safest approach given uva ursi's potential for toxicity at high doses or over time.

Each ingredient & the kinds of drugs it affects

For each ingredient in Kidney/Urinary Tract with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Uva Ursi leaf extract6 drug types · 803 drugs

Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, uva ursi may decrease the metabolism of CYP2C19 substrates.
In vitro, uva ursi appears to inhibit cytochrome CYP2C19. This effect has not been reported in humans.

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

Theoretically, uva ursi may decrease the metabolism of CYP3A4 substrates.
In vitro, uva ursi appears to inhibit CYP3A4. This effect has not been reported in humans.

Likelihood Possible Evidence D
Glucuronidated Drugs

Theoretically, uva ursi may increase levels of drugs metabolized by glucuronidation.
In vitro, uva ursi extract appears to strongly inhibit UDP-glucuronosyltransferase (UGT) 1A1 (UGT1A1). However, uva ursi extract does not appear to inhibit UGT1A1 in animal models. This effect has not been reported in humans.

Likelihood Possible Evidence D
Lithium

Theoretically, uva ursi may increase lithium levels, necessitating a decrease in dose.
Uva ursi may have diuretic properties. Diuretics may increase lithium reabsorption with sodium in the proximal tubule of the kidney. Theoretically, uva ursi might reduce excretion and increase levels of lithium.

Likelihood Probable Evidence D
Urinary Acidifying Agents

Effects of uva ursi in the urinary tract may be reduced by urinary acidifying agents.
Uva ursi seems to work best in alkaline urine. Theoretically, taking uva ursi with medications known to acidify the urine may decrease any effects of uva ursi on the urinary tract.

Likelihood Possible Evidence D
P-Glycoprotein Substrates

Theoretically, uva ursi may alter the levels of drugs transported by P-glycoprotein.
In vitro, uva ursi appears to inhibit the multi-drug transporter protein, P-glycoprotein. This effect has not been reported in humans.

Likelihood Possible Evidence D
Uva Ursi leaf extract full monograph & interactions

Dandelion root extract7 drug types · 457 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, taking dandelion root along with anticoagulant or antiplatelet drugs might increase the risk of bruising and bleeding.
In vitro research suggests that dandelion root inhibits platelet aggregation.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, dandelion might increase the risk for hypoglycemia when used with antidiabetes drugs.
Laboratory research suggests that dandelion extract may have moderate alpha-glucosidase inhibitor activity and might also increase insulin secretion. Also, in a case report, a 58-year-old woman with type 2 diabetes who was being treated with insulin developed hypoglycemia 2 weeks after beginning to eat salads containing dandelion.

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

Theoretically, dandelion might increase levels of drugs metabolized by CYP1A2.
Laboratory research suggests that dandelion might inhibit CYP1A2. So far, this interaction has not been reported in humans. However, until more is known, watch for an increase in the levels of drugs metabolized by CYP1A2 in patients taking dandelion.

Likelihood Possible Evidence D
Glucuronidated Drugs

Theoretically, dandelion might increase the clearance of drugs that are UDP-glucuronosyltransferase substrates.
There is some preliminary evidence that dandelion might induce UDP-glucuronosyltransferase, a phase II enzyme.

Likelihood Possible Evidence D
Lithium

Theoretically, through diuretic effects, dandelion might reduce excretion and increase levels of lithium.
Animal research suggests that dandelion has diuretic properties. As diuretics can increase serum lithium levels, the dose of lithium might need to be decreased when taken with dandelion.

Likelihood Probable Evidence D
Potassium-Sparing Diuretics

Theoretically, dandelion might increase the risk of hyperkalemia when taken with potassium-sparing diuretics.
Dandelion contains significant amounts of potassium.

Likelihood Possible Evidence D
Quinolone Antibiotics

Theoretically, dandelion might lower fluoroquinolone levels.
Animal research shows that dandelion reduces absorption of ciprofloxacin and can lower levels by 73%. However, this effect has not been reported in humans.

Likelihood Possible Evidence D
Dandelion root extract full monograph & interactions

Parsley8 drug types · 443 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, parsley might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
Animal research suggests that parsley has antiplatelet effects.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, parsley might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research suggests that parsley might decrease blood glucose. Monitor blood glucose levels closely. Dose adjustments might be necessary.

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

Theoretically, parsley might increase serum levels of CYP1A2 substrates.
Laboratory research suggests that parsley can inhibit CYP1A2.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, parsley might enhance or interfere with the effects of diuretic drugs.
Animal research suggests that parsley seed extract increases urine elimination. Parsley leaf and root might also interfere with diuretic therapy due their purported aquaretic effects.

Likelihood Possible Evidence D
Pentobarbital (Nembutal)

Theoretically, parsley might increase the duration of pentobarbital effects.
Animal research suggests that parsley juice prolongs the action of pentobarbital, perhaps by decreasing cytochrome P450 levels. It is not known if this occurs in humans or if this applies to other barbiturates or sedatives.

Likelihood Possible Evidence D
Sirolimus (Rapamune)

Theoretically, large quantities of parsley might increase sirolimus levels.
In one case report, an adult female with a history of kidney transplant presented with elevated blood sirolimus levels, approximately 4-7 times greater than previous measures, after daily consumption of a juice containing approximately 30 grams of parsley for 7 days. Sirolimus levels returned to normal a week after the parsley juice was discontinued.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, large amounts of parsley leaf and root might decrease the effects of warfarin.
Parlsey contains vitamin K.

Likelihood Possible Evidence D
Aspirin

Theoretically, aspirin might increase the severity of allergic reactions to parsley.
In one case, severe urticaria and swelling were reported after taking aspirin with parsley in an individual with a known mild parsley allergy.

Likelihood Unlikely Evidence D
Parsley full monograph & interactions

Vitamin A4 drug types · 387 drugs

Retinoids

Concomitant use of retinoids with vitamin A supplements might produce supratherapeutic vitamin A levels.
Retinoids, which are vitamin A derivatives, could have additive toxic effects when taken with vitamin A supplements.

Likelihood Probable Evidence D
Hepatotoxic Drugs

Theoretically, taking high doses of vitamin A in combination with other potentially hepatotoxic drugs might increase the risk of liver disease.
The tolerable upper intake level (UL) is the highest level of intake that is likely to pose no risk of adverse effects. Doses of vitamin A above the UL can cause hepatotoxicity, ranging from elevated liver enzymes to liver failure.

Likelihood Possible Evidence C
Tetracycline Antibiotics

Theoretically, taking tetracycline antibiotics with high doses of vitamin A can increase the risk of pseudotumor cerebri.
Benign intracranial hypertension (pseudotumor cerebri) can occur with tetracyclines and with acute or chronic vitamin A toxicity. Case reports suggest that taking tetracyclines and vitamin A concurrently can increase the risk of this condition. Avoid high doses of vitamin A in people taking tetracyclines chronically.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, high doses of vitamin A could increase the risk of bleeding with warfarin.
Vitamin A toxicity is associated with hemorrhage and hypoprothrombinemia, possibly due to vitamin K antagonism. Advise patients taking warfarin to avoid doses of vitamin A above the tolerable upper intake level of 10,000 IU/day for adults.

Likelihood Possible Evidence D
Vitamin A full monograph & interactions

Corn silk extract5 drug types · 290 drugs

Antidiabetes Drugs

Theoretically, taking corn silk with antidiabetes drugs might increase the risk of hypoglycemia.
Animal research in diabetic mice shows that taking corn silk extract lowers fasting blood glucose levels.

Likelihood Possible Evidence D
Antihypertensive Drugs

Taking corn silk extract with antihypertensive drugs might increase the risk of hypotension.
Clinical research in both hypertensive and normotensive adults shows that taking corn silk extract lowers systolic and diastolic blood pressure.

Likelihood Possible Evidence D
Corticosteroids

Taking corn silk with corticosteroids might increase the risk of hypokalemia.
Clinical research shows that taking corn silk extract increases the urinary excretion of potassium.

Likelihood Possible Evidence D
Diuretic Drugs

Taking corn silk with diuretic drugs might increase the risk of adverse effects such as hyponatremia and hypokalemia.
Clinical research shows that taking corn silk extract increases urine volume and promotes the urinary excretion of sodium and potassium. Some patients may require electrolyte supplementation.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, suddenly stopping, starting, or changing corn silk treatment may alter the effects of warfarin.
Corn silk contains vitamin K. Individuals taking warfarin should consume a consistent daily amount of corn silk to maintain consistent anticoagulation.

Likelihood Likely Evidence D

Kidney/Urinary Tract by ProEnzol: Common Questions

Does Kidney/Urinary Tract by ProEnzol interact with any medications?
Yes. Based on its ingredients, Kidney/Urinary Tract has a known interaction with 1,284 medications, including 9 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Kidney/Urinary Tract contains 6 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 ProEnzol safe to take if I'm pregnant or breastfeeding?
No—uva ursi is rated likely unsafe in pregnancy because it may stimulate the uterus, and parsley is also likely unsafe at medicinal doses for the same reason. Data for dandelion during pregnancy is insufficient; there isn't enough information either way. For breastfeeding, uva ursi and parsley lack enough safety information, so they should be avoided. Corn silk is possibly safe while breastfeeding, and vitamin A in normal amounts is appropriate. Talk with your doctor or pharmacist about whether this product is right for you if you're pregnant or nursing.
What is uva ursi supposed to do?
Uva ursi leaf extract has been traditionally used to support urinary tract health, but our data rates it possibly ineffective for urinary tract infections specifically. It may work better in alkaline urine and is meant for short-term use only.
Can I take ProEnzol long-term?
No. Uva ursi in particular can be toxic with prolonged use, and the safety data advises using it only for short-term treatment. Corn silk safety data are also limited for long-term use. Talk with your doctor about how long it's appropriate for you.
What is pHysioProtease and does it interact with medications?
pHysioProtease is a proteolytic enzyme—a protein-digesting enzyme. We do not hold interaction data for it, so we cannot confirm whether it interacts with medications. Ask your pharmacist if you're concerned about a specific drug you take.
Does this product have any fillers?
Yes—the inactive ingredients are plant fiber and water, which serve as binders and fillers to form the capsule.
What are the most common side effects I might notice?
Uva ursi commonly causes diarrhea, nausea, stomach upset, and vomiting. Dandelion may cause diarrhea, heartburn, and stomach discomfort. Parsley and corn silk are generally well tolerated. Corn silk may lower potassium levels with prolonged use. Stop and contact your doctor if you experience severe symptoms.
