HelloPharmacist Scorecard of CranRich Super Strength by Natural Factors
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
CranRich Super Strength contains one active ingredient: organic cranberry (Vaccinium macrocarpon) concentrate in a softgel form. The inactive ingredients are organic flaxseed oil, sunflower lecithin, organic beeswax, and the softgel capsule itself — these are excipients that deliver the cranberry extract.
Does it work?
Moderate evidence
The evidence for cranberry is clearest for urinary tract infections (UTIs), where it's rated possibly effective — meaning there's some support, though not overwhelming. For other conditions listed, like age-related cognitive decline, benign prostatic hyperplasia (enlarged prostate), cancer prevention, fatty liver disease, and chronic fatigue, the evidence we hold is insufficient to rate whether it works.
If you're considering this for a condition beyond UTI support, talk with your pharmacist or doctor about what the broader research shows.
How safe is it?
Well-documented data
Cranberry from food is generally well tolerated. This product contains a concentrated supplement dose, and concentrated cranberry supplements haven't been studied as thoroughly as the whole fruit or juice, so check with your provider first.
The most common side effects are diarrhea and stomach discomfort; nausea and vomiting have also been reported, especially with larger daily amounts. Skin redness and itching have been reported in one person.
Concentrated supplement doses are different from food amounts — ask your pharmacist or doctor whether this product is appropriate for you before starting.
Meds to double-check
Moderate interaction found
Before you take CranRich, check whether you're on any of these: cholesterol-lowering statins (especially atorvastatin/Lipitor), blood pressure medications like nifedipine (Procardia), blood thinners like warfarin (Coumadin), or NSAIDs like diclofenac (Voltaren). Cranberry can raise the levels of all these drug types and boost their side effects.
Use the medication checker below to search your exact prescriptions.
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.
CranRich is possibly effective for UTI support and is generally well tolerated in most people. If you take a statin, blood pressure medication, blood thinner, or pain reliever, you must check your exact drugs before adding this supplement — cranberry can raise their levels.
Pregnant or breastfeeding people can use it (it's rated likely safe), but concentrated supplements are less studied than whole cranberry, so a quick conversation with your pharmacist or doctor is worth it.

CranRich Super Strength by Natural Factors Drug Interactions
HelloPharmacist Interaction Report
CranRich Super Strength by Natural Factors contains a single active ingredient — cranberry concentrate — which does interact with several medications.
The most serious concern is with cholesterol-lowering statins like atorvastatin (Lipitor). Cranberry can slow how your body clears these drugs, raising their levels and potentially causing muscle breakdown and liver damage; one case reported upper back pain, muscle breakdown (rhabdomyolysis), and abnormal liver function in a patient taking atorvastatin with cranberry juice for 2 weeks.
Read the full breakdown — every affected drug type, severity by severity
Cranberry also has Moderate interactions with blood pressure medications like nifedipine (Procardia) and blood thinners like warfarin (Coumadin). With nifedipine, cranberry may increase drug levels.
With warfarin, the evidence is mixed — some case reports suggest cranberry raises the blood-thinning effect (increasing bruising and bleeding risk), but clinical studies conflict. Additionally, there are Minor interactions documented with pain relievers in the NSAID class, though human evidence for these is weak.
Additionally, cranberry shows Minor interactions with a broader group of medications metabolized by a liver enzyme called CYP2C9, though again the research is contradictory — lab studies suggest an effect, but real-world use hasn't confirmed it.
Altogether, these interactions span 702 individual medications. Before you start this supplement, use the medication checker on this page to look up any blood pressure drugs, cholesterol medications, blood thinners, or pain relievers you're taking.

For each ingredient in CranRich Super Strength 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.
CranRich organic Cranberry (Vaccinium macrocarpon) Concentrate
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.
