Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 7 of its 7 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Kidney Complex contains 7 active herbal ingredients: uva ursi leaf extract, barberry root extract, cranberry fruit extract, corn silk extract, three-leaf caper bark extract, saw palmetto fruit extract, and stinging nettle leaf extract. Each is included as a concentrated extract to support urinary and kidney function through traditional herbal use.

The capsules also contain inactive ingredients—hypromellose (the capsule material), ascorbyl palmitate, silica, and cellulose—which are fillers and binders that help deliver the active herbs.

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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: kidney and urinary tract support.
  • We looked for evidence on: Benign prostatic hyperplasia (BPH), Kidney stones (nephrolithiasis), Non-neurogenic lower urinary tract symptoms (LUTS), Nocturnal enuresis, Overactive bladder, Prostatitis — and 4 related terms.
  • The strongest evidence on file: Cranberry is rated "Possibly Effective" for Urinary tract infections (UTIs) (Natural Medicines).
  • Also on file: Uva Ursi is rated "Possibly Ineffective" for Urinary tract infections (UTIs).
  • Also on file: Saw Palmetto is rated "Possibly Ineffective" for Benign prostatic hyperplasia (BPH).

The evidence for these ingredients is mixed. Cranberry is possibly effective for urinary tract infections, while uva ursi is rated possibly ineffective for UTIs despite its long traditional use—suggesting it may not work as well as hoped.

Stinging nettle is possibly effective for diabetes. For most other claimed uses—bronchitis, benign prostatic hyperplasia, various heart and blood sugar conditions—the evidence we have is insufficient to say whether these herbs help or not.

None of these ingredients have strong, reliable proof of benefit for the purposes this product implies.

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 7 of the 7 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 7 of 7.
  • General safety write-ups exist for 7 of 7.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Uva ursi is generally well tolerated in short-term, low doses but can be toxic at high doses or with prolonged use; diarrhea, nausea, and stomach upset are common, and very high doses (30 grams or more) may be fatal. It should be avoided in pregnancy and while breastfeeding.

Barberry has a rare but serious case report of liver injury and blood cell damage after just two weeks of use; it's not safe in pregnancy or lactation. Cranberry is likely safe during pregnancy and lactation, though concentrated supplements haven't been well studied.

Corn silk is generally well tolerated short-term but should be avoided in pregnancy and, due to unknown risks, in breastfeeding. Three-leaf caper and saw palmetto lack pregnancy and breastfeeding safety data and should be avoided.

Stinging nettle is likely unsafe in pregnancy and breastfeeding safety is unknown. Gastrointestinal upset (diarrhea, nausea, constipation) is common across most ingredients.

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?
  • 7 of the 7 matched ingredients can interact with medications — Corn Silk, Uva Ursi, European Barberry, Stinging Nettle, Capers, among others.
  • 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: 1,336 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 Kidney Complex, check with your doctor or pharmacist if you take any of these: blood thinners or antiplatelet drugs (warfarin, aspirin, clopidogrel); diabetes medications; blood pressure medications; lithium; statins or other cholesterol drugs; diuretics; corticosteroids; birth control pills or hormone therapy; immunosuppressants like cyclosporine; sedative or CNS depressant drugs; or any medication that your liver processes through CYP2C19, CYP3A4, or glucuronidation pathways. Because this product affects so many drug-metabolizing enzymes, your own pharmacist or doctor is the best person to clear it for your specific medications.

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.

Kidney Complex is a multi-ingredient herbal blend aimed at urinary and kidney support, but the evidence for most of its ingredients is weak or absent. More importantly, it carries significant interaction risks with blood thinners, diabetes medications, blood pressure drugs, lithium, and many others metabolized by your liver.

If you take any regular medication—especially for diabetes, blood pressure, bleeding, mood, or heart rhythm—talk with your doctor or pharmacist before starting this product to confirm it's safe for you.

Barberry (Berberis vulgaris) root extract8 drug types · 1,212 drugs

Anticholinergic Drugs

Theoretically, taking European barberry with anticholinergic drugs might cause additive effects.
In vitro evidence suggests that European barberry might have anticholinergic properties.

Likelihood Possible Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, European barberry may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro and animal evidence suggest that berberine, a constituent of European barberry, might inhibit platelet aggregation. Theoretically, European barberry might have a similar effect.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, taking European barberry with antidiabetes drugs might increase the risk of hypoglycemia.
Preliminary clinical evidence suggests that European barberry juice reduces fasting glucose levels in patients with type 2 diabetes who are also taking antidiabetes drugs. Additionally, some animal studies show that berberine, a constituent of European barberry, has antiglycemic potential. Monitor blood glucose levels closely.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, taking European barberry with antihypertensive drugs might increase the risk of hypotension.
Animal and human research suggests that European barberry extracts can have hypotensive effects.

Likelihood Possible Evidence D
Cholinergic Drugs

Theoretically, taking European barberry with cholinergic drugs might decrease the effects of cholinergic drugs.
In vitro evidence suggests that European barberry might have anticholinergic properties.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, concomitant use with drugs that have sedative properties may cause additive effects.
Animal research suggests that berberine, a constituent of European barberry, might have sedative effects. Theoretically, European barberry might have a similar effect.

Likelihood Possible Evidence D
Cyclosporine (Neoral, Sandimmune)

Theoretically, concomitant use with cyclosporine may cause additive effects.
Berberine, a constituent of European barberry, can reduce the metabolism and increase serum levels of cyclosporine. This effect is attributed to the ability of berberine to inhibit cytochrome P450 3A4 (CYP3A4), which metabolizes cyclosporine. Theoretically, European barberry might have a similar effect.

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

Theoretically, European barberry might increase the levels and clinical effects of CYP3A4 substrates.
There is very preliminary evidence suggesting that berberine, a constituent of European barberry, might inhibit the CYP3A4 enzyme. Theoretically, European barberry might have a similar effect.

Uva-Ursi (Arctostaphylos uva-ursi) leaf extract6 drug types · 804 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 (Arctostaphylos uva-ursi) leaf extract full monograph & interactions

Cranberry (Vaccinium macrocarpon) fruit extract6 drug types · 714 drugs

Atorvastatin (Lipitor)

Theoretically, cranberry might increase levels and adverse effects of atorvastatin.
In one case report, a patient taking atorvastatin experienced upper back pain, rhabdomyolysis, and abnormal liver function after drinking cranberry juice 16 ounces daily for 2 weeks. Theoretically, this may have been caused by inhibition of cytochrome P450 3A4 (CYP3A4) enzymes by cranberry juice, as atorvastatin is a CYP3A4 substrate. Creatinine kinase and liver enzymes normalized within 2 weeks of stopping cranberry juice. Patients taking atorvastatin should avoid large quantities of cranberry juice.

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

Theoretically, cranberry might increase the levels and adverse effects of CYP3A4 substrates.
A case of upper back pain, rhabdomyolysis, and abnormal liver function has been reported for a patient taking atorvastatin, a CYP3A4 substrate, in combination with cranberry juice 16 ounces daily for 2 weeks. Creatinine kinase and liver enzymes normalized within 2 weeks of stopping cranberry juice. Also, animal research suggests that cranberry juice, administered intraduodenally 30 minutes prior to nifedipine, a CYP3A4 substrate, inhibits nifedipine metabolism and increases the area under the concentration-time curve by 1.6-fold compared to control.

Likelihood Possible Evidence D
Nifedipine (Procardia)

Theoretically, cranberry might increase the levels and adverse effects of nifedipine.
Animal research suggests that cranberry juice, administered intraduodenally 30 minutes prior to nifedipine treatment, inhibits nifedipine metabolism and increases the area under the concentration-time curve by 1.6-fold compared to control. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, cranberry might increase the levels and adverse effects of warfarin. However, research is conflicting.
There is contradictory evidence about the effect of cranberry juice on warfarin. Case reports have linked cranberry juice consumption to increases in the international normalized ratio (INR) in patients taking warfarin, resulting in severe spontaneous bleeding and excessive postoperative bleeding. Daily consumption of cranberry sauce for one week has also been linked to an increase in INR in one case report. In a small study in healthy young males, taking a high dose of 3 grams of cranberry juice concentrate capsules, equivalent to 57 grams of fruit daily, for 2 weeks produced a 30% increase in the area under the INR-time curve after a single 25-mg dose of warfarin. However, 3 very small clinical studies in patients stabilized on warfarin reported that cranberry juice 250 mL once or twice daily for 7 days (27% cranberry juice or pure cranberry juice) or 240 mL once daily for 14 days does not significantly increase INR or affect plasma warfarin levels. The reasons for these discrepant findings are unclear. It is possible that the form and dose of cranberry may play a role, as cranberry extracts and juices contain different constituents. Additionally, an in vitro study evaluating 5 different cranberry juices found varying effects, with only a cranberry concentrate, and not diluted cranberry juices, inhibiting CYP2C9. However, this concentrate did not inhibit CYP2C9 activity in humans.

Likelihood Possible Evidence B
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, cranberry might increase the levels and adverse effects of CYP2C9 substrates. However, research is conflicting.
There is contradictory evidence about the effect of cranberry on CYP2C9 enzymes. In vitro evidence suggests that flavonoids in cranberry inhibit CYP2C9 enzymes. However, clinical research shows that cranberry juice does not significantly affect the levels, metabolism, or elimination of the CYP2C9 substrates flurbiprofen or diclofenac. Also, in patients stabilized on warfarin, drinking cranberry juice 250 mL daily for 7 days does not significantly increase the anticoagulant activity of warfarin, a CYP2C9 substrate. Additional pharmacokinetic research shows that cranberry juice does not increase peak plasma concentrations or area under the concentration-time curve of warfarin.

Likelihood Unlikely Evidence B
Diclofenac (Voltaren, Others)

Theoretically, cranberry might modestly increase the levels and adverse effects of diclofenac.
In vitro evidence suggests that cranberry juice inhibits diclofenac metabolism by human liver microsomes. However, drinking cranberry juice does not seem to affect diclofenac metabolism in humans.

Corn (Zea mays) style and stigma 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

Saw Palmetto (Serenoa repens) fruit std. extract3 drug types · 174 drugs

Anticoagulant/Antiplatelet Drugs

Saw palmetto might increase the risk of bleeding with anticoagulant or antiplatelet drugs.
Saw palmetto is reported to prolong bleeding time. Theoretically, it might increase the risk of bleeding when used concomitantly with anticoagulant or antiplatelet drugs.

Likelihood Possible Evidence D
Contraceptive Drugs

Saw palmetto might reduce the effectiveness of contraceptive drugs.
Saw palmetto might have antiestrogenic effects. Theoretically, it might interfere with contraceptive drugs taken concomitantly.

Likelihood Possible Evidence B
Estrogens

Saw palmetto might reduce the effectiveness of estrogens.
Saw palmetto might have antiestrogenic effects. Theoretically, it might interfere with estrogens taken concomitantly.

Stinging Nettle (Urtica dioica) leaf extract4 drug types · 164 drugs

Antidiabetes Drugs

Theoretically, stinging nettle might have additive effects with antidiabetes drugs.
Clinical research shows that stinging nettle might decrease blood glucose levels in patients with diabetes.

Likelihood Possible Evidence B
Diuretic Drugs

Theoretically, combining stinging nettle with diuretic drugs may have additive effects.
Animal research suggests that the above ground parts and roots of stinging nettle may have a diuretic effect.

Likelihood Possible Evidence D
Lithium

Theoretically, stinging nettle might reduce excretion and increase levels of lithium.
Animal research suggests that stinging nettle has diuretic and natriuretic properties, which could alter the excretion of lithium. The dose of lithium might need to be decreased.

Likelihood Possible Evidence D
Warfarin (Coumadin)

There is some concern that stinging nettle might decrease the effects of anticoagulant drugs such as warfarin.
Stinging nettle contains a significant amount of vitamin K. When taken in large quantities, this might interfere with the activity of warfarin.

Likelihood Possible Evidence D

Three-Leaf Caper (Crateva magna) bark extract1 drug type · 86 drugs

Antidiabetes Drugs

Some preliminary clinical research shows that taking caper fruit extract 1200 mg daily for 2 months can lower fasting blood glucose and glycated hemoglobin (HbA1c) in patients with type 2 diabetes who are already taking antidiabetes drugs. However, other research does not support this effect. Until more is known, monitor blood glucose levels closely. Medication dose adjustments may be necessary.
Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), and others.

Kidney Complex by Genestra Brands: Common Questions

Does Kidney Complex by Genestra Brands interact with any medications?
Yes. Based on its ingredients, Kidney Complex has a known interaction with 1,336 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Kidney Complex contains 7 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 this safe to take if I'm pregnant or breastfeeding?
No. Uva ursi, barberry, saw palmetto, and stinging nettle should be avoided in pregnancy because of potential effects on the uterus and hormone balance. While cranberry is likely safe during pregnancy and lactation, most of the other ingredients either lack safety data or are marked unsafe for breastfeeding. Talk with your doctor before considering any herbal supplement during pregnancy or while nursing.
Can this actually help with urinary tract infections?
Cranberry is possibly effective for UTIs, but uva ursi—a traditional UTI remedy in this blend—is rated possibly ineffective based on available evidence. The product isn't a substitute for medical treatment if you have an active infection; see your doctor for that.
What are the most common side effects?
Gastrointestinal upset is most likely—nausea, diarrhea, stomach upset, or constipation. Uva ursi at high doses can cause serious toxicity (convulsions, shortness of breath, delirium), but that's rare at normal doses. Barberry has a rare report of severe liver and blood cell injury. Most people tolerate the individual herbs at standard doses, but watch for digestive symptoms.
Why does this product interact with so many medications?
The herbs in Kidney Complex contain compounds that slow down how your liver breaks down drugs. When your body clears medications more slowly, they can build up to higher, sometimes unsafe levels—or their effects may be weakened if the herb works in the opposite direction. That's why liver-processing interactions matter: they touch hundreds of different drugs.
Is it okay to take this long-term?
Uva ursi should only be used short-term; prolonged use can be toxic. Barberry safety data for long-term use are limited. Most other ingredients haven't been studied long enough to know. Short-term use is generally safer, but talk with your doctor about how long you plan to take it.
Can I take this with my blood pressure medication?
Both corn silk and barberry can lower blood pressure, so combining them with blood pressure drugs could drop your pressure too far. Saw palmetto and stinging nettle also have effects on blood pressure or blood vessel function. Your doctor or pharmacist needs to review your specific medication and blood pressure history before you start.
