HelloPharmacist Scorecard of Cranberry Extract by Herbadiet
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
Herbadiet Cranberry Extract is a single-ingredient supplement: cranberry extract in a vegetable cellulose capsule. That's it — no added fillers or binders beyond the capsule material itself.
Does it work?
Moderate evidence
The evidence best supports cranberry for urinary tract infection (UTI) prevention — it's rated possibly effective for that use. For other conditions in our data, including cognitive decline, prostate health, cancer prevention, fatty liver disease, and chronic fatigue, the evidence isn't strong enough to rate either way.
How safe is it?
Well-documented data
Cranberry extract is generally well tolerated. The most common side effects are mild — diarrhea and stomach discomfort — and skin redness or itching has been reported rarely.
That said, concentrated supplement doses haven't been studied as much as whole cranberry in food amounts, so talk with your doctor or pharmacist before starting this product. During pregnancy and lactation, cranberry is rated likely safe.
Remember, though, this supplement is not a replacement for medical treatment of an actual infection — if you have a UTI or other illness, see your doctor.
Meds to double-check
Moderate interaction found
Before taking this product, check with your pharmacist if you take a statin like atorvastatin (Lipitor), a blood thinner like warfarin (Coumadin), a heart medication like nifedipine (Procardia), or an anti-inflammatory drug like diclofenac (Voltaren). Cranberry may raise the levels and side effects of these 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.
If you're looking to support urinary tract health, cranberry extract has decent evidence behind it and is usually easy on your stomach. But you must check your medications first, especially if you take a statin, blood thinner, or heart drug — cranberry can change how your body processes these.
Talk to your pharmacist before you start.

Cranberry Extract by Herbadiet Drug Interactions
HelloPharmacist Interaction Report
Herbadiet Cranberry Extract contains cranberry extract, which interacts with a number of medications.
The most serious concern is with cholesterol-lowering statins like atorvastatin (Lipitor), where cranberry may slow how your body clears the drug and raise its levels. One patient taking atorvastatin with high-dose cranberry juice developed muscle breakdown (rhabdomyolysis), back pain, and liver problems that improved when the cranberry stopped.
Read the full breakdown — every affected drug type, severity by severity
Cranberry also has Moderate interactions with blood thinners (warfarin/Coumadin) — it may increase the thinning effect and raise your bleeding risk — and with the heart medication nifedipine (Procardia), which cranberry can cause to build up in your system. Additionally, Minor interactions are documented with anti-inflammatory drugs like diclofenac (Voltaren) and with other medications broken down by the liver enzyme CYP2C9, though human evidence here is mixed.
Altogether, these interactions span 702 individual medications. Before you start this supplement, run your exact medications through the checker on this page — especially if you take a statin, blood thinner, or heart medication.

For each ingredient in Cranberry Extract with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Cranberry extract
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.
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.
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.
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.
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.
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.
