HelloPharmacist Scorecard of Cranberry Bladder Control by Whitaker Nutrition

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

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 1 of its 3 active ingredients.
  • “Go-Less Blend” is a proprietary blend — the label gives one combined amount (300 mg) without saying how much of each component you get.

This product contains three active ingredients: pumpkin extract, soy extract, and cranberry concentrate, plus a proprietary blend called Go-Less Blend. Pumpkin extract is included for its possible benefit in benign prostatic hyperplasia (BPH, or enlarged prostate).

Soy extract has been studied for diabetes, cholesterol, bone health, and blood pressure. Cranberry concentrate is used primarily for urinary tract infections (UTIs).

The capsule also contains inactive ingredients: gelatin, magnesium stearate, and silica.

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: Healthy bladder and urinary function.
  • We looked for evidence on: Benign prostatic hyperplasia (BPH), Interstitial cystitis, Overactive bladder, Radiation-induced cystitis, Urinary odor, Urinary tract infections (UTIs) — and 3 related terms.
  • The strongest evidence on file: Pumpkin is rated "Possibly Effective" for Benign prostatic hyperplasia (BPH) (Natural Medicines).
  • Also on file: Cranberry is rated "Possibly Effective" for Urinary tract infections (UTIs).
  • Also on file: Soy is rated "Possibly Ineffective" for Benign prostatic hyperplasia (BPH).

The evidence here is mixed. Pumpkin extract is possibly effective for BPH, though the data on its usefulness for UTIs or other urinary conditions isn't established.

Soy extract is possibly effective for diabetes, high cholesterol, bone health, and high blood pressure. Cranberry concentrate is possibly effective for UTIs but has insufficient evidence for other conditions like cognitive decline, BPH, or cancer.

For Go-Less Blend, we hold no separate effectiveness data — that depends on what's inside it.

The evidence, ingredient by ingredient Pumpkin Soy 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 3 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.

Pumpkin and cranberry are generally well tolerated at typical doses. The most common side effects across the product are mild: abdominal discomfort, diarrhea, nausea, and bloating.

Soy can trigger allergic reactions in some people, including skin rash and itching. Rare but serious reactions (anaphylaxis with pumpkin) have been reported.

Pregnancy and lactation data are incomplete: soy is likely safe during both, but pumpkin safety during these periods hasn't been well studied, and cranberry is likely safe during both. We hold no pregnancy or lactation data for Go-Less Blend.

Side effects, ingredient by ingredient Pumpkin Soy Cranberry

Meds to double-check

Major interaction found
Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 3 of the 3 matched ingredients can interact with medications — Pumpkin, Cranberry, Soy.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium.
  • For scale: 1,099 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 your exact medications against these categories. The most serious concern is MAOIs (antidepressants) used with soy — that's a Major interaction.

Moderate interactions affect blood pressure drugs, diabetes medications, hormone replacement therapy, blood thinners (warfarin), thyroid medication (levothyroxine), caffeine, certain cholesterol and heart drugs (atorvastatin, nifedipine), water pills (diuretics), and lithium. Minor interactions involve some pain relievers like diclofenac.

The bottom line

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

This product pairs cranberry and pumpkin with soy for bladder and urinary support, but it's not a replacement for treatment of actual infections. If you take an MAOI antidepressant, blood pressure medication, diabetes drugs, a blood thinner, thyroid medication, or a cholesterol medication, check with us or your pharmacist before starting — soy and cranberry in particular can affect how these work.

Soy allergies are also a consideration.

Cranberry concentrate6 drug types · 712 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.

Likelihood Unlikely Evidence B
Cranberry concentrate full monograph & interactions

Soy extract12 drug types · 611 drugs

Monoamine Oxidase Inhibitors (Maois)

Taking soy products containing high amounts of tyramine along with MAOIs can increase the risk of hypertensive crisis.
Fermented soy products such as tofu and soy sauce contain tyramine, a naturally occurring chemical that affects blood pressure regulation. The metabolism of tyramine is decreased by MAOIs. Consuming more than 6 mg of tyramine while taking an MAOI can increase the risk of hypertensive crisis. The amount of tyramine in fermented soy products is usually less than 0.6 mg per serving; however, there can be significant variation depending on the specific product used, storage conditions, and length of storage. Storing one brand of tofu for a week can increase tyramine content from 0.23 mg to 4.8 mg per serving. Advise patients taking MAOIs to avoid fermented soy products that contain high amounts of tyramine.

Likelihood Likely Evidence C
Antidiabetes Drugs

Soy can lower blood glucose and have additive effects with antidiabetes drugs.
Clinical research shows that whole soy diets and soy-based meals reduce fasting glucose levels in diabetic and non-diabetic individuals. Also, individuals following a soy-based meal replacement plan seem to require lower doses of sulfonylureas and metformin to manage blood glucose levels when compared with individuals following a diet plan recommended by the American Diabetes Association.

Likelihood Possible Evidence A
Antihypertensive Drugs

Theoretically soy protein may have additive effects with antihypertensive drugs and increase the risk of hypotension.
Although some contradictory research exists, most clinical evidence suggests that consuming soy protein modestly reduces systolic and diastolic blood pressure in individuals with prehypertension or hypertension.

Likelihood Possible Evidence A
Caffeine

Theoretically, soy might reduce the clearance of caffeine.
Soy contains genistein. Taking genistein 1 gram daily for 14 days seems to inhibit caffeine clearance and metabolism in healthy females. This effect has been attributed to inhibition of the cytochrome P450 1A2 (CYP1A2) enzyme, which is involved in caffeine metabolism. It is unclear if this effect occurs with the lower amounts of genistein found in soy.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, soy might have additive effects when used with diuretic drugs.
Animal research suggests that genistein, a soy isoflavone, increases diuresis within 6 hours of subcutaneous administration in rats. The effects seem to be similar to those of furosemide. This effect has not been reported in humans.

Likelihood Possible Evidence D
Estrogens

Theoretically, soy might competitively inhibit the effects of estrogen replacement therapy.
Soy contains phytoestrogens and has been shown to have estrogenic activity in some patients. Although this has not been demonstrated in humans, theoretically, concomitant use of soy with estrogen replacement therapy might reduce the effects of the estrogen replacement therapy.

Likelihood Possible Evidence D
Levothyroxine (Synthroid, Others)

Soy products might reduce the absorption of levothyroxine in some patients.
Preliminary clinical research and a case report suggest that soy-based formulas inhibit the absorption of levothyroxine in infants with congenital hypothyroidism. A levothyroxine dosage increase may be needed for infants with congenital hypothyroidism while using soy-based formulas, and the dose may need to be reduced when soy-based formulas are no longer administered. However, in postmenopausal adults, clinical research shows that taking a single dose of soy extract containing isoflavones 60 mg along with levothyroxine does not affect the oral bioavailability of levothyroxine.

Likelihood Possible Evidence B
Progesterone

Theoretically, combining soy isoflavones with transdermal progesterone may worsen bone density.
Clinical research suggests that significant bone loss may occur in females with osteoporosis who receive a combination of transdermal progesterone with soy milk containing isoflavones when compared with placebo, soy milk alone, or progesterone alone.

Likelihood Possible Evidence A
Tamoxifen (Nolvadex)

Theoretically, estrogenic soy isoflavones might alter the effects of tamoxifen.
Laboratory research suggests that genistein and daidzen, isoflavones from soy, can antagonize the antitumor effects of tamoxifen under some circumstances; however, soy isoflavones might have different effects when used at different doses. A relatively low in vitro concentration of soy isoflavones such as 1 microM/L seems to interfere with tamoxifen, whereas high in vitro concentrations such as those >10 microM/L might actually enhance tamoxifen effects. People on a high-soy diet have soy isoflavones levels ranging from 0.1-6 microM/L. Until more is known, advise patients taking tamoxifen to avoid therapeutic use of soy products.

Likelihood Possible Evidence B
Warfarin (Coumadin)

Theoretically, soy might interfere with the effects of warfarin.
Soy milk has been reported to decrease the international normalized ratio (INR) in a patient taking warfarin. The mechanism of this interaction is not known. However, animal and in vitro research suggests that soy may also inhibit platelet aggregation. Dosing adjustments for warfarin may be necessary.

Likelihood Possible Evidence D
Antibiotic Drugs

Theoretically, antibiotics may decrease the activity of soy isoflavones.
Intestinal bacteria are responsible in part for converting soy isoflavones into their active forms. Antibiotics may decrease the amount of intestinal bacteria and decrease its ability to convert isoflavones.

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

Soy might modestly induce CYP2C9 enzymes. However, this effect does not seem to be clinically significant.
In vitro research suggests that an unhydrolyzed soy extract might induce CYP2C9. However, the significance of this interaction is likely minimal. In healthy females taking a specific extract of soy (Genistein Soy Complex, Source Naturals), blood levels of losartan, a CYP2C9 substrate, were not significantly affected.

Lithium

Pumpkin might reduce excretion and increase levels of lithium.
Pumpkin is thought to have diuretic properties. Theoretically, this might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Cranberry Bladder Control by Whitaker Nutrition: Common Questions

Does Cranberry Bladder Control by Whitaker Nutrition interact with any medications?
Yes. Based on its ingredients, Cranberry Bladder Control has a known interaction with 1,098 medications, including 9 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Cranberry Bladder Control contains 3 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?
Soy extract is likely safe during pregnancy and breastfeeding. Cranberry is also likely safe during both. Pumpkin extract, though fine as a food, hasn't been studied well enough in concentrated supplement form during pregnancy or breastfeeding — talk with your doctor or pharmacist for personalized advice before taking it.
What's pumpkin extract doing in a bladder-control supplement?
Pumpkin extract is included because it's possibly effective for benign prostatic hyperplasia (enlarged prostate), which can affect urinary function in men. The evidence for it helping with urinary tract infections or other bladder conditions isn't established yet.
Can I use this instead of antibiotics if I have a urinary tract infection?
No. Cranberry concentrate is possibly effective for UTI prevention, but it's not a treatment for an active infection and shouldn't replace medical care. If you have signs of a UTI — pain on urination, urgency, or fever — see your doctor.
What are the most common side effects?
Mild stomach upset is most likely: abdominal discomfort, diarrhea, nausea, and bloating have been reported. Soy can trigger allergic reactions like rash or itching in some people. If you're allergic to soy, avoid this product.
Does this have a lot of fillers?
The inactive ingredients are gelatin, magnesium stearate, and silica — typical capsule materials. They're minimal and standard for this form.
What's Go-Less Blend, and do you have data on it?
Go-Less Blend is a proprietary blend — the product facts don't list its component ingredients individually. We can't tell you what interactions or effects it might have without knowing what's inside it. Ask the manufacturer if you want that information.
