HelloPharmacist Scorecard of Urobiol 450 mg by GM Germa

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

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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

Urobiol contains one active ingredient: phyllanthus niruri leaf extract, commonly known as chanca piedra, at 450 mg per capsule. The capsule itself is made from gelatin, with cellulose and magnesium stearate as inactive ingredients.

Does it work?

Moderate 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
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: Helps maintain healthy kidneys.
  • We looked for evidence on: Kidney stones (nephrolithiasis), Urinary tract infections (UTIs), Gallbladder disease, Kidney function, Renal health, Urinary system support.
  • The strongest evidence on file: Chanca Piedra is rated "Possibly Effective" for Kidney stones (nephrolithiasis) (Natural Medicines).
  • Also on file: Chanca Piedra is rated "Insufficient Reliable Evidence To Rate" for Gallbladder disease, Urinary tract infections (UTIs).

The evidence for chanca piedra is mixed. For kidney stones, the data shows it's possibly effective — some studies suggest it may help prevent or manage them.

For hepatitis B, the research indicates it's likely ineffective, so this supplement shouldn't be relied on for that condition. For anemia of chronic disease and benign prostate enlargement, there isn't enough reliable evidence yet to say whether it works.

The evidence, ingredient by ingredient Chanca Piedra

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 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Chanca piedra is generally well tolerated for short-term use, but high-quality safety data are limited. The most common side effects you might notice are abdominal pain, nausea, vomiting, and fatigue.

The supplement should be avoided during pregnancy and while breastfeeding — there isn't enough safety information in either situation.

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Chanca Piedra.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium.
  • For scale: 1,021 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 Urobiol, check with your pharmacist if you're on blood thinners or antiplatelet drugs (like warfarin or aspirin), diuretics, lithium, or medications that go through your liver's CYP3A4 or CYP1A2 pathways (a common group including some statins and antidepressants). Also mention if you take blood pressure pills or diabetes 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.

Urobiol might be worth considering if you're dealing with kidney stones and interested in herbal approaches, but it's not proven for other conditions like hepatitis or prostate issues. If you take blood thinners, diuretics, lithium, or drugs metabolized by your liver, check with your pharmacist first — this product has documented interactions with all of these.

Pregnancy and breastfeeding are off-limits.

Phyllanthus niruri Leaf Extract8 drug types · 1,020 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, chanca piedra might increase the risk of bleeding when used concomitantly with anticoagulant/antiplatelet drugs.
In vitro research suggests that methyl brevifolincarboxylate, a constituent isolated from chanca piedra, can inhibit platelet aggregation. This effect has not been reported in humans.

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

Theoretically, chanca piedra might reduce the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that chanca piedra extract increases CYP1A2 activity. Theoretically, chanca piedra might increase metabolism of CYP1A2 substrates and lower serum concentrations. This interaction has not been reported in humans.

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

Theoretically, use of chanca piedra might increase the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that chanca piedra extract inhibits CYP3A4. Theoretically, chanca piedra might increase the levels of CYP3A4 substrates. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, concomitant use of chanca piedra with diuretics might increase diuresis.
Some preliminary clinical research in adults with hypertension shows that chanca piedra has diuretic properties. However, higher quality research in adults with kidney stones shows taking chanca piedra does not increase urine volume when compared with placebo. Until more is known, use cautiously in patients taking diuretic drugs.

Likelihood Possible Evidence D
Lithium

Theoretically, chanca piedra might reduce excretion and increase levels of lithium.
Some preliminary clinical research in adults with hypertension shows that chanca piedra has diuretic properties. However, higher quality research in adults with kidney stones shows that taking chanca piedra does not increase urine volume when compared with placebo. Until more is known, use cautiously in patients taking lithium. The dose of lithium might need to be decreased.

Likelihood Possible Evidence D
Norepinephrine (Levophed)

Theoretically, chanca piedra may reduce the effects of norepinephrine.
Animal research suggests that methyl brevifolincarboxylate, a constituent isolated from chanca piedra, can reverse blood vessel contraction caused by norepinephrine.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, concomitant use with antidiabetes drugs might affect glucose control and increase the risk of hypoglycemia.
Animal research suggests that chanca piedra can have hypoglycemic effects. However, a small clinical study in adults with diabetes shows that chanca piedra extract 25 grams orally daily for 1 week does not lower fasting or postprandial blood glucose levels.

Likelihood Unlikely Evidence D
Antihypertensive Drugs

Theoretically, concomitant use of chanca piedra with antihypertensive drugs might have additive blood pressure lowering effects.
Animal research suggests that chanca piedra can decrease blood pressure. However, this effect was not observed in most hypertensive patients treated with chanca piedra for 10 days.

Urobiol 450 mg by GM Germa: Common Questions

Does Urobiol 450 mg by GM Germa interact with any medications?
Yes. Based on its ingredients, Urobiol 450 mg has a known interaction with 1,020 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Urobiol 450 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
What is chanca piedra and what is it supposed to do?
Chanca piedra, the active ingredient in Urobiol, is a plant extract traditionally used for kidney health. Research shows it's possibly effective for kidney stones, but it's not proven to work for other conditions like hepatitis B, anemia, or prostate problems.
What are the side effects?
Most people tolerate it okay short-term, but the most common side effects are abdominal pain, nausea, vomiting, and fatigue. A thorough safety evaluation hasn't been done, so there may be other effects we don't know about yet.
Can I take this if I'm pregnant or breastfeeding?
No — there isn't enough safety information in either situation, so you should avoid this product during pregnancy and while breastfeeding. Talk with your doctor or pharmacist about safer options.
Does this interact with my blood pressure medication?
Theoretically, chanca piedra might add to the blood pressure-lowering effect of your medication, though this wasn't seen in most patients studied. It's still worth checking with your pharmacist to be sure, especially if you take multiple blood pressure drugs.
I'm on a blood thinner — is this safe?
Lab studies suggest chanca piedra might increase bleeding risk when combined with blood thinners like warfarin or aspirin. Don't start this without checking with your pharmacist first — they can help you decide if it's okay for you.
How many active ingredients does this have?
Just one: chanca piedra leaf extract at 450 mg per capsule. The rest is the gelatin capsule and standard fillers like cellulose.
