HelloPharmacist Scorecard of Diuretic Formula 450 mg 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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 23, 2026

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 2 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (450 mg) without saying how much of each component you get.

This formula contains 2 active ingredients: horsetail and Java tea, both traditional diuretic plants. Horsetail is rich in silica and has been used historically to support urinary health, while Java tea (also called orthosiphon) is traditionally employed as a diuretic to encourage fluid loss.

The capsule itself is made from gelatin and water.

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: mild diuretic and urinary tract support.
  • We looked for evidence on: Urinary tract infections (UTIs), Urinary incontinence, fluid retention, kidney function, bladder health.
  • The closest evidence on file: Java Tea is rated "Insufficient Reliable Evidence To Rate" for Urinary tract infections (UTIs) (Natural Medicines).
  • Also on file: Horsetail is rated "Insufficient Reliable Evidence To Rate" for Urinary tract infections (UTIs), Urinary incontinence.

The evidence supporting horsetail and Java tea for their marketed uses is not yet established. Our data shows insufficient reliable evidence to rate horsetail for urinary incontinence, weight loss, sore throat, or hair loss.

Similarly, Java tea shows insufficient reliable evidence for high blood pressure or urinary tract infections. If you're considering this product for a specific health goal, talk it through with your doctor or pharmacist to explore what the current research actually supports.

The evidence, ingredient by ingredient Horsetail 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 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.

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

Crude horsetail contains a compound called thiaminase that can deplete thiamine (vitamin B1) with prolonged use — though Canadian products are required to be certified free from this. One case report linked horsetail use in pregnancy to a child's thiamine deficiency.

Java tea is generally well tolerated short-term, but human safety data are limited. Safety data for horsetail during pregnancy and breastfeeding are not adequate; the same applies to Java tea.

If you're pregnant, planning pregnancy, or breastfeeding, talk with your doctor or pharmacist before taking this product.

Side effects, ingredient by ingredient Horsetail Java Tea

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 — Java Tea, Horsetail.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications; lithium.
  • For scale: 292 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 this product, check with your doctor or pharmacist if you take lithium (horsetail and Java tea may raise its level), antidiabetes drugs (horsetail may lower blood sugar too far), other diuretics (horsetail may increase potassium loss), antihypertensive drugs (Java tea may lower blood pressure too much), or HIV medications including efavirenz or NRTIs (horsetail may reduce their effectiveness).

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 combines two traditional diuretic herbs with several documented interactions, most notably with lithium, diabetes medications, blood pressure drugs, and HIV antiretrovirals. If you take any prescription medications — especially for blood sugar, blood pressure, mood, or infection — check your exact drug list with your doctor or pharmacist before starting.

Short-term use in healthy adults without these medications may be considered, but the evidence for what this formula actually accomplishes is not yet established.

Horsetail5 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.

Java Tea2 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.

Diuretic Formula 450 mg by TerraVita Premium Collection: Common Questions

Does Diuretic Formula 450 mg by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Diuretic Formula 450 mg has a known interaction with 292 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Diuretic Formula 450 mg contains 2 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 while I'm pregnant or breastfeeding?
Safety data for both horsetail and Java tea during pregnancy and breastfeeding are not adequate. Talk with your doctor or pharmacist about whether this product is right for you in these situations.
What's the most common side effect I might notice?
From horsetail, the most frequent side effects are abdominal bloating, more frequent bowel movements, and nausea. Java tea safety data are limited, so we know less about side effects from that ingredient.
How long is it safe to take this?
Horsetail is considered acceptable for short-term use in healthy adults, but long-term use carries real risks — including potential thiamine depletion with prolonged consumption. Talk with your pharmacist about how long you should take it.
Does this actually work for water retention or bloating?
The evidence for horsetail and Java tea in these uses is not yet established. Our data show insufficient reliable evidence to support their use for weight loss, urinary incontinence, or other common reasons people try diuretic formulas.
What are the inactive ingredients?
The capsule contains gelatin and water — no other fillers or binders.
