HelloPharmacist Scorecard of Kidney Complex Powder by TerraVita Premium Collection

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.

From our pharmacy team — supplement deep dive

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 0 of its 4 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (1,000 mg) without saying how much of each component you get.

Kidney Complex Powder contains four active ingredients. Horsetail powder, corn silk powder, kidney bean powder, and Java tea powder make up the formulation.

The product has no inactive fillers or other ingredients listed.

Does it work?

Insufficient evidence
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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Kidney and urinary tract health support.
  • We looked for evidence on: Kidney stones (nephrolithiasis), Nocturnal enuresis, Prostatitis, Urinary incontinence, Urinary tract infections (UTIs), Bladder health — and 2 related terms.
  • The closest evidence on file: Corn Silk is rated "Insufficient Reliable Evidence To Rate" for Kidney stones (nephrolithiasis) (Natural Medicines).
  • Also on file: Corn Silk is rated "Insufficient Reliable Evidence To Rate" for Prostatitis, Urinary tract infections (UTIs), Nocturnal enuresis.
  • Also on file: Java Tea is rated "Insufficient Reliable Evidence To Rate" for Urinary tract infections (UTIs).

The evidence we hold does not establish that any of the active ingredients are effective for the conditions listed. Horsetail shows insufficient reliable evidence for urinary incontinence, obesity, tonsillitis, and androgenic alopecia (pattern hair loss).

Corn silk shows insufficient reliable evidence for angina, cardiovascular disease, heart failure, depression, diabetes, and fatigue. Java tea shows insufficient reliable evidence for high blood pressure and urinary tract infections.

Because the ingredients are in a proprietary blend, we cannot determine individual doses, which further limits what the evidence can tell us about this specific product.

The evidence, ingredient by ingredient Horsetail Corn Silk Java Tea

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 2 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Horsetail is generally well tolerated for short-term use in healthy adults, but long-term use carries real risks. The most common side effects are abdominal bloating, increased bowel movements, and nausea.

Crude horsetail contains thiaminase, an enzyme that can cause thiamine (vitamin B1) deficiency with prolonged consumption — Canadian products are required to be thiaminase-free. One rare case report linked topical horsetail to a skin reaction (seborrheic dermatitis).

Horsetail is not recommended during pregnancy or while breastfeeding due to insufficient safety data. Corn silk is generally well tolerated for short-term use, though human safety data are limited.

The main concern is potassium loss (hypokalemia) with prolonged use, and sodium loss (hyponatremia) is also possible. Topical corn silk can cause skin rashes (dermatitis) and hives.

Corn silk should be avoided during pregnancy. It is possibly safe while breastfeeding, but safety data are limited.

Java tea is generally well tolerated short-term; no adverse effects are documented in our data. It should be avoided during pregnancy and breastfeeding due to insufficient safety information.

We hold no safety data for kidney bean powder.

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?
  • 3 of the 3 matched ingredients can interact with medications — Corn Silk, Java Tea, Horsetail.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium.
  • For scale: 317 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 Powder, check whether you take antidiabetes drugs, antihypertensive drugs (blood pressure medications), diuretic drugs (water pills), lithium, antiretroviral drugs (HIV medications like efavirenz), warfarin (a blood thinner), or corticosteroids. All of these have documented Moderate-severity interactions with ingredients in this product.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with insufficient evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product is designed to support kidney function, but the evidence we have doesn't establish that its ingredients work for any condition. If you take blood pressure medications, diabetes drugs, diuretics, lithium, antiretroviral drugs (HIV medications), or warfarin, you should check your exact medications with the tool on this page before starting.

Talk to your pharmacist or doctor, especially if you're pregnant, breastfeeding, or plan to use this long-term.

Corn Silk, Powder5 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

Horsetail, Powder5 drug types · 188 drugs

Antidiabetes Drugs

Theoretically, taking horsetail with antidiabetes drugs might increase the risk of hypoglycemia.
Equisetum myriochaetum has demonstrated hypoglycemic activity in clinical research. In an animal diabetic model, Equisetum giganteum had hypoglycemic effects. It is unclear whether other horsetail species have hypoglycemic effects.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, taking horsetail with diuretic drugs might increase potassium loss and the risk of hypokalemia.
Laboratory research shows that various species of horsetail have diuretic properties. Due to its diuretic effects, there has been concern that taking horsetail along with potassium-depleting diuretics might increase the risk for hypokalemia. However, pharmacokinetic research in humans shows that taking horsetail 900 mg daily for 4 days does not affect urinary excretion of electrolytes, including potassium and sodium, despite having a diuretic effect similar to taking hydrochlorothiazide 25 mg daily. It is unclear if taking horsetail for a longer duration would affect electrolyte levels. Until more is known, use with caution.

Likelihood Possible Evidence D
Efavirenz (Sustiva)

Theoretically, horsetail might decrease the levels and clinical effects of efavirenz.
In two case reports, patients were found to have detectable viral loads when taking horsetail-containing supplements along with an antiretroviral regimen that included efavirenz. In one case, the antiretroviral regimen included zidovudine, lamivudine, and efavirenz; in the other case, the regimen consisted of emtricitabine, tenofovir disoproxil fumarate, and efavirenz. One month after discontinuing horsetail, the viral loads became undetectable in both cases. The exact mechanism of this interaction is unknown. It is also unclear if this interaction is specific to efavirenz or if it is related to various components of antiretroviral therapy.

Likelihood Possible Evidence D
Lithium

Theoretically, horsetail might increase the levels and adverse effects of lithium.
Animal research suggests that horsetail has diuretic properties. Theoretically, due to these potential diuretic effects, horsetail might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Likelihood Possible Evidence D
Nucleoside Reverse Transcriptase Inhibitors (Nrtis)

Theoretically, horsetail might decrease the levels and clinical effects of NRTIs.
In two case reports, patients were found to have detectable viral loads when taking horsetail-containing supplements along with an antiretroviral therapy. In one case, the antiretroviral regimen included zidovudine, lamivudine, and efavirenz; in the other case, the regimen consisted of emtricitabine, tenofovir disoproxil fumarate, and efavirenz. One month after discontinuing the supplement, the viral loads became undetectable in both cases. The exact mechanism of these interactions is unknown. It is also unclear if these interactions are specific to NRTIs or if they are related to various components of antiretroviral therapy.

Likelihood Possible Evidence D

Java Tea, Powder2 drug types · 173 drugs

Antihypertensive Drugs

Some preliminary clinical evidence suggests that Java tea has antihypertensive effects. Further, animal research suggests that Java tea has diuretic properties. Theoretically, taking Java tea with other antihypertensive drugs might increase the effects and risk for hypotension with these drugs.

Likelihood Probable Evidence D
Lithium

Animal research suggests that Java tea has diuretic properties. Theoretically, due to these effects, Java tea might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Kidney Complex Powder by TerraVita Premium Collection: Common Questions

Does Kidney Complex Powder by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Kidney Complex Powder has a known interaction with 317 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Kidney Complex Powder contains 4 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.
Can I take this if I'm pregnant or breastfeeding?
Horsetail and Java tea should not be used during pregnancy or while breastfeeding — there isn't enough safety data. Corn silk is possibly safe while breastfeeding but should be avoided in pregnancy. Talk with your doctor or pharmacist for personalized advice before starting this product.
What are the side effects of horsetail in this formula?
The most common side effects are abdominal bloating, increased bowel movements, and nausea. Prolonged use of crude horsetail can cause thiamine deficiency — though Canadian products are required to be free from the enzyme that causes this. A rare skin reaction has been reported with topical use.
What does each ingredient in this powder do?
Horsetail is traditionally used for urinary incontinence and other conditions, though evidence doesn't confirm it works. Corn silk is used for urinary tract support and heart health without established proof. Java tea is used for kidney and urinary health. Kidney bean powder is included but we hold no interaction or safety data for it.
Does this product actually work for kidney problems?
The evidence we hold doesn't establish that horsetail, corn silk, or Java tea are effective for any condition, including kidney or urinary issues. None of these ingredients have sufficient reliable evidence supporting their use.
Is this safe to use long-term?
No. Horsetail and Java tea are considered safe for short-term use in healthy adults only; long-term use carries real risks, especially thiamine deficiency with horsetail. Corn silk also has limited long-term safety data. Talk to your pharmacist about how long you should take this.
Can I take this if I'm on a water pill for blood pressure?
No, not without talking to your doctor first. Both horsetail and corn silk are diuretics themselves and may increase potassium loss and electrolyte imbalances when combined with diuretic drugs. Your doctor may need to monitor your levels or adjust your medication.
