HelloPharmacist Scorecard of Cranberry 475 mg by AN Amazing Nutrition Amazing Formulas

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

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.

This product contains one active ingredient: cranberry fruit extract at 475 mg per capsule. Cranberry is the whole-fruit extract, which preserves the compounds believed to be active in the plant.

The capsule itself is made from gelatin and silicon dioxide, which are inactive ingredients that hold the extract together.

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: fight urinary tract infections and support urinary tract health.
  • We looked for evidence on: Urinary tract infections (UTIs), Catheter-related infections, Radiation-induced cystitis, Overactive bladder, Urinary odor, bladder health — and 1 related terms.
  • The strongest evidence on file: Cranberry is rated "Possibly Effective" for Urinary tract infections (UTIs) (Natural Medicines).
  • Also on file: Cranberry is rated "Insufficient Reliable Evidence To Rate" for Urinary odor, Overactive bladder, Catheter-related infections, Radiation-induced cystitis.

Cranberry is possibly effective for urinary tract infections (UTIs) — that's the one use with enough solid evidence behind it. For other conditions listed here — age-related cognitive decline, benign prostatic hyperplasia (enlarged prostate), cancer prevention, fatty liver disease, and chronic fatigue — the evidence isn't established.

That doesn't mean cranberry doesn't help with those, just that we don't have reliable data on it yet.

The evidence, ingredient by ingredient 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 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.

Cranberry is generally well tolerated when eaten as a food or taken as a supplement. The most common side effects are diarrhea and stomach discomfort; a few people have reported nausea or skin irritation, though that's rare.

Very large doses — several liters of juice a day — can cause significant digestive upset. Because concentrated supplements haven't been as well studied as whole cranberries, talk with your doctor or pharmacist before starting this product to make sure it fits your health situation.

Side effects, ingredient by ingredient Cranberry

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?
  • 1 of the 1 matched ingredient can interact with medications — Cranberry.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 713 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 before taking if you use a statin (like atorvastatin), a calcium channel blocker for blood pressure (like nifedipine), or warfarin or another blood thinner — cranberry may increase their levels and side effects. Also ask your doctor or pharmacist about any other medications your liver processes, since cranberry can affect how quickly your body clears them.

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.

If you have a urinary tract infection and want to explore cranberry as part of your care, this extract may help — though it's not a replacement for medical treatment. Anyone taking a statin, blood pressure medication, or blood thinner should clear it first with their own doctor or pharmacist.

For other uses, evidence is too limited to say whether it works.

Cranberry fruit extract6 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.

Cranberry 475 mg by AN Amazing Nutrition Amazing Formulas: Common Questions

Does Cranberry 475 mg by AN Amazing Nutrition Amazing Formulas interact with any medications?
Yes. Based on its ingredients, Cranberry 475 mg has a known interaction with 712 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Cranberry 475 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.
Is cranberry safe to take while pregnant or breastfeeding?
Cranberry is rated likely safe during pregnancy and lactation. That said, concentrated supplements haven't been studied as thoroughly as whole cranberries in food, so ask your doctor or midwife before taking this supplement to be sure it's right for your situation.
Can cranberry actually prevent or treat a urinary tract infection?
Cranberry is possibly effective for UTIs — meaning there's decent evidence it may help — but it's not a substitute for medical treatment. If you think you have a UTI, see your doctor; cranberry can be a complement to what they recommend, not a replacement.
What are the most common side effects?
Diarrhea and stomach discomfort are the main ones people report. Nausea and vomiting can happen too, and one person reported skin redness and itching. Most people tolerate it fine, but if your stomach gets upset, it may not be the right fit for you.
Does it matter that this is a concentrated extract instead of whole cranberry?
Yes — concentrated supplements haven't been studied as much as eating whole cranberries or drinking cranberry juice. Since we know less about how these concentrated doses work in your body, check with your doctor or pharmacist first.
Will this help with other conditions like memory problems or prostate health?
We don't have reliable evidence that cranberry helps with those. The only condition we have solid data for is urinary tract infection. If you're interested in cranberry for something else, talk it over with your doctor to see what the research actually shows.
