HelloPharmacist Scorecard of Cranberry Powder by BulkSupplements.com
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
This product contains one active ingredient: cranberry powder. That's it—no other actives.
There are no inactive ingredients listed. Cranberry is a berry that's been studied for its possible effects on urinary tract infections and a handful of other conditions.
The powder form concentrates the compounds from the fruit, which is why the safety notes on file recommend checking with your provider before using concentrated supplements like this one, rather than eating fresh cranberries or diluted juice.
Does it work?
Moderate evidence
Cranberry powder is possibly effective for urinary tract infections (UTIs)—that's the one use with decent supporting evidence. For everything else on file—age-related cognitive decline, benign prostatic hyperplasia (enlarged prostate), cancer, nonalcoholic fatty liver disease, and chronic fatigue syndrome—the evidence isn't established in the data we hold.
If you're considering this for a UTI, talk it over with your doctor or pharmacist about whether it makes sense for your situation.
How safe is it?
Well-documented data
Cranberry is generally well tolerated as a food or supplement. When taken orally in typical amounts, the most common side effects are diarrhea and stomach discomfort.
In very large doses—3 to 4 liters of juice per day, for example—it can cause more serious gastrointestinal upset, especially in young children. Clinical trials have also reported nausea, vomiting, and diarrhea, even at lower doses taken over weeks.
One person reported skin redness and itching. Cranberry in normal food amounts is likely fine, but concentrated supplement doses like this powder haven't been well studied, so check with your provider first.
During pregnancy and lactation, cranberry is rated likely safe, but because the safety of concentrated supplements hasn't been established, ask your doctor or pharmacist before taking this product if you're pregnant or breastfeeding.
Meds to double-check
Moderate interaction found
Before taking this product, double-check any statins (like atorvastatin), blood thinners (like warfarin), blood pressure medications (like nifedipine), and pain relievers (like diclofenac) with your doctor or pharmacist. Cranberry can theoretically raise the levels of these drugs and their side effects.
If you take any of these or other regular medications, search for them using the tool on this page.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
Cranberry powder may help with urinary tract infections, though it's not a substitute for medical treatment. The main concern is interactions with medications—especially statins, blood thinners, and blood pressure drugs—so if you take any regular medication, check it against the tool on this page and talk with your doctor or pharmacist before starting.
Most people tolerate it well, but stomach upset and diarrhea can happen, especially at high doses.

Cranberry Powder by BulkSupplements.com Drug Interactions
HelloPharmacist Interaction Report
Cranberry Powder by BulkSupplements.com contains one active ingredient—cranberry powder—which interacts with a number of medications, mostly through effects on how your liver processes them.
The most serious documented concern is with atorvastatin (Lipitor) and other cholesterol drugs in the same class: a patient taking atorvastatin developed muscle breakdown (rhabdomyolysis), upper back pain, and abnormal liver function after consuming cranberry juice at high doses for 2 weeks. Altogether, these interactions span 713 individual medications.
Read the full breakdown — every affected drug type, severity by severity
Cranberry can theoretically raise levels of blood pressure drugs like nifedipine (Procardia), which animal research suggests could happen through enzyme interference. It may also affect blood thinners like warfarin (Coumadin)—case reports link cranberry juice to increased bleeding risk, though the evidence is mixed.
Other drug categories affected include pain relievers like diclofenac (Voltaren), though real-world evidence there is conflicting.
Before you start cranberry powder, run a search for any prescription or over-the-counter medications you're taking using the tool on this page. If you take a statin, blood thinner, blood pressure medication, or any other regular drug, check with your doctor or pharmacist first.

For each ingredient in Cranberry Powder 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 powder
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.
