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 4 of its 4 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

UTFight contains four active ingredients. D-mannose is a simple sugar that's been studied for certain genetic conditions and urinary tract infections.

Burdock root extract is an herbal ingredient with a long history of use, though modern evidence for its benefits is still developing. Parsley leaf and stem extract is a concentrated form of the culinary herb, and cranberry extract comes from the fruit and is commonly used for urinary tract health.

The capsule also contains cellulose, an inactive ingredient that serves as a filler.

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: urinary tract infection fighting support.
  • We looked for evidence on: Urinary tract infections (UTIs), Cystitis, Bladder infection, Urinary tract infection prevention, Urinary tract health.
  • The strongest evidence on file: Cranberry is rated "Possibly Effective" for Urinary tract infections (UTIs) (Natural Medicines).
  • Also on file: D-mannose is rated "Possibly Ineffective" for Urinary tract infections (UTIs).
  • Also on file: Burdock is rated "Insufficient Reliable Evidence To Rate" for Urinary tract infections (UTIs).

For urinary tract infections specifically, cranberry extract is possibly effective according to our data, though it's not a substitute for medical treatment if you have a confirmed infection. D-mannose, on the other hand, is rated possibly ineffective for UTIs in the evidence we hold.

The effectiveness of parsley leaf, stem extract and burdock root extract for UTIs hasn't been established in our data—there's insufficient reliable evidence. If you're considering this product for UTI prevention or treatment, talk with your doctor or pharmacist about whether it fits your situation.

The evidence, ingredient by ingredient D-mannose Burdock Parsley Cranberry

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 4 of the 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

D-mannose is generally well tolerated short-term, but long-term safety data are limited; the safety information we have advises caution unless your doctor advises otherwise. Common side effects are bloating, diarrhea, and nausea.

Burdock is likely safe as a food and for short-term use, though human safety data are limited. Serious allergic reactions including anaphylaxis are rare but possible.

Parsley is well tolerated at low to moderate doses, but large doses may be unsafe; very high doses carry rare risks of serious effects. Cranberry is generally well tolerated; most common side effects are diarrhea and gastrointestinal discomfort.

For pregnancy, avoid medicinal amounts of burdock due to possible effects on the uterus. Parsley in medicinal or large amounts may stimulate the uterus, so stick to food amounts only in pregnancy.

For breastfeeding, there isn't enough safety data on D-mannose or concentrated parsley supplements, so talk with your doctor or pharmacist. Burdock use while breastfeeding should also be avoided due to lack of safety information.

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 4 matched ingredients can interact with medications — Burdock, Parsley, Cranberry.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 987 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 your medications against this product if you take blood thinners like warfarin (Coumadin) or other anticoagulants or antiplatelet drugs—parsley and burdock may increase bleeding risk (Moderate). If you take diabetes medications, diuretics, cholesterol or blood pressure drugs, or sedatives, ask your pharmacist to screen for interactions with parsley and cranberry.

Parsley may also interact with the transplant drug sirolimus (Rapamune) and aspirin in people with parsley allergy.

Cranberry 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.

Parsley Leaf, Stem Extract8 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.

UTFight by Herbs SRA: Common Questions

Does UTFight by Herbs SRA interact with any medications?
Yes. Based on its ingredients, UTFight has a known interaction with 986 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
UTFight 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 UTFight if I'm on warfarin or another blood thinner?
Not without checking first. Parsley in this formula contains vitamin K, which can reduce warfarin's effect, and both parsley and burdock may increase bleeding risk with anticoagulants. You must talk with your doctor or pharmacist before adding UTFight to a blood thinner—they can check your exact medications and advise you.
Will this help my urinary tract infection?
Cranberry extract in UTFight is possibly effective for UTIs, but this product is not a substitute for medical treatment of a confirmed infection. D-mannose is rated possibly ineffective for UTIs in our data. If you have symptoms of a UTI, see your doctor or pharmacist—you may need antibiotics or other care.
What are the most common side effects?
D-mannose and cranberry may cause bloating, diarrhea, nausea, or gastrointestinal discomfort. Parsley and burdock are generally well tolerated at the doses likely in this product. If you experience persistent digestive upset, talk with your pharmacist.
Is UTFight safe if I'm pregnant or breastfeeding?
There isn't enough safety data to say it's safe for either pregnancy or breastfeeding. Parsley in medicinal amounts may stimulate the uterus, and burdock should be avoided in pregnancy. Talk with your doctor or pharmacist about whether this product is right for you in pregnancy or while nursing.
Does this interact with diabetes or heart medications?
Yes, potentially. Parsley may lower blood sugar with diabetes drugs, and both parsley and cranberry may raise levels of certain blood pressure and cholesterol medications. Use the interaction checker on this page with your exact drugs, or ask your pharmacist.
What is D-mannose and why is it in here?
D-mannose is a simple sugar that has been studied for a rare genetic disorder and for urinary tract health. In this product it's intended to support urinary tract function, though evidence for UTIs is limited. It's generally well tolerated, but high-quality long-term safety data are lacking.
