HelloPharmacist Scorecard of Pomegranate 500 mg by 21st Century

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

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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains 2 active ingredients: pomegranate fruit and pomegranate powdered extract. Both forms contain the same active compounds—polyphenols and other plant compounds—that account for pomegranate's effects on blood pressure and other functions.

The capsule also contains inactive ingredients like cellulose, oat fiber, rice bran, and magnesium compounds that serve as fillers and binders.

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

This product doesn't appear to be marketed for a specific use, so we graded Pomegranate's overall clinical evidence instead.

Moderate

Some clinical evidence supports Pomegranate for:

Why this rating?
  • The label markets general wellness (“antioxidant health support”), not a specific health condition, so there is no single claim to grade against clinical-evidence data.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Hypertension — rated "Possibly Effective" (Natural Medicines).

The evidence on pomegranate's effectiveness is mixed. For high blood pressure (hypertension), it's rated possibly effective—research shows it can modestly lower blood pressure in some people.

For cholesterol (hyperlipidemia) and diabetes, the data suggests it's probably not effective. For nonalcoholic fatty liver disease, there isn't enough reliable evidence to rate it one way or the other.

If you're considering this for blood pressure support, talk with your doctor about whether it belongs in your overall plan.

The evidence, ingredient by ingredient Pomegranate

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.

Pomegranate fruit and juice are generally well tolerated when used as food. The most common side effects are mild stomach issues—diarrhea and gas appear in small percentages of people using the supplement form, and at higher doses (3000 mg of extract daily), nausea, abdominal pain, constipation, and vomiting affected a small number of trial participants.

The data notes that concentrated extracts should be used with caution due to limited safety information. Pomegranate is rated possibly safe in pregnancy and lactation, but there isn't extensive data on supplement use during these times—talk with your doctor or pharmacist if you're pregnant or breastfeeding.

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 — Pomegranate.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 923 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, double-check with your doctor or pharmacist if you take blood pressure medications (antihypertensive drugs), blood thinners like warfarin, ACE inhibitors, the statin rosuvastatin, seizure medications like carbamazepine, or any drug your doctor says your liver breaks down through CYP2D6, CYP2C9, or CYP3A4 pathways. Pomegranate can alter how your body processes or responds to these drugs.

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.

Pomegranate 500 mg may help with high blood pressure, though the evidence is modest. The real concern is its interactions with blood pressure meds, blood thinners, and certain other drugs—you need to run your medication list through the checker before you start.

If you don't take any of those medications and you're interested in it for general heart or antioxidant support, it's generally well tolerated, but mild stomach upset is possible. Check with your own doctor or pharmacist first.

Pomegranate9 drug types · 922 drugs

Ace Inhibitors (Aceis)

Theoretically, taking pomegranate with ACEIs might increase the risk of adverse effects.
Pomegranate juice is thought to have ACE inhibitor-like effects.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, taking pomegranate with antihypertensive drugs might increase the risk of hypotension.
Consuming pomegranate juice can modestly lower blood pressure.

Likelihood Possible Evidence B
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, pomegranate might increase levels of drugs metabolized by CYP2D6.
In vitro, pomegranate juice inhibits CYP2D6. However, the clinical significance of this potential interaction in humans is not known.

Likelihood Possible Evidence D
Rosuvastatin (Crestor)

Theoretically, taking pomegranate with rosuvastatin might increase the risk of adverse effects.
In one case, a patient taking rosuvastatin 5 mg every other day in combination with ezetimibe 10 mg daily developed rhabdomyolysis after drinking pomegranate juice 200 mL twice weekly for 3 weeks. This patient had a history of elevated creatine kinase levels while not receiving any statin treatment. This suggests a possible underlying myopathy and predisposition to rhabdomyolysis.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, pomegranate might increase warfarin levels and increase the risk of bleeding. Also, discontinuing regular consumption of pomegranate juice might decrease warfarin levels.
In one case report, a patient had a stable, therapeutic bleeding time, as measured by international normalized ratio (INR), while taking warfarin in combination with pomegranate juice 2-3 times per week. The patient became subtherapeutic within about 10 days after discontinuing pomegranate juice, which required a warfarin dose increase. In another case report, a patient with a stable INR for over one year presented with an INR of 14. The patient noted no changes to medications or diet but did report consuming around 3 liters of pomegranate juice over the previous week. The patient's INR stabilized upon moderation of pomegranate juice consumption. The mechanism of this potential interaction is unclear.

Likelihood Possible Evidence D
Carbamazepine (Tegretol)

Theoretically, taking pomegranate with carbamazepine might increase the risk of adverse effects, although research suggests this interaction is unlikely to be clinically significant.
Animal research shows that pomegranate juice may inhibit cytochrome P450 3A4 (CYP3A4) metabolism of carbamazepine and increase levels of carbamazepine by 1.5 times without prolonging the elimination half-life. This suggests that pomegranate juice inhibits intestinal CYP3A4, but might not inhibit hepatic CYP3A4. However, some human research suggests that pomegranate does not significantly inhibit CYP3A4 drug metabolism in humans.

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

Theoretically, pomegranate might increase levels of drugs metabolized by CYP2C9.
Some animal and in vitro research shows that pomegranate juice inhibits intestinal, but not hepatic, CYP2C9 isoenzyme activity. However, clinical research shows that neither pomegranate juice nor pomegranate extract have a significant effect on CYP2C9 activity in humans.

Likelihood Unlikely Evidence B
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, pomegranate might increase levels of drugs metabolized by CYP3A4, but most research suggests this interaction is unlikely to be clinically significant.
Pomegranate contains several polyphenols that have individually been shown to inhibit CYP3A4. However, there is contradictory evidence about the effect of whole pomegranate juice on CYP3A4 activity. In vitro, pomegranate juice significantly inhibits the CYP3A4 enzyme, with comparable inhibition to grapefruit juice. In an animal model, pomegranate juice inhibits CYP3A4 metabolism of carbamazepine and increases levels of carbamazepine by 1.5 times; however, in human volunteers, drinking a single glass of pomegranate juice 240 mL or taking 200 mL daily for 2 weeks does not significantly affect levels of the CYP3A4 substrate midazolam after oral or intravenous administration. Another study in healthy volunteers shows that consuming pomegranate juice 300 mL three times daily for three days also does not significantly affect levels of simvastatin, a CYP3A4 substrate This suggests that pomegranate is unlikely to significantly affect levels of CYP3A4 substrates in humans.

Likelihood Unlikely Evidence B
Tolbutamide (Orinase)

Theoretically, pomegranate might increase levels of tolbutamide, although research suggests this interaction is unlikely to be clinically significant.
Animal research shows that pomegranate juice inhibits the cytochrome P450 2C9 (CYP2C9) metabolism of tolbutamide. Pomegranate juice increased tolbutamide levels by 1.2 times without prolonging the elimination half-life. This suggests that pomegranate juice inhibits intestinal CYP2C9, but might not inhibit hepatic CYP2C9. Despite this evidence, clinical research shows that neither pomegranate juice nor pomegranate extract have a significant effect on CYP2C9 activity in humans. This interaction does not appear to be clinically significant in humans.

Pomegranate 500 mg by 21st Century: Common Questions

Does Pomegranate 500 mg by 21st Century interact with any medications?
Yes. Based on its ingredients, Pomegranate 500 mg has a known interaction with 922 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Pomegranate 500 mg contains 2 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.
Can I take this if I'm on blood pressure medication?
Probably not without checking first. Pomegranate lowers blood pressure on its own, so combining it with your medication might drop your pressure too low. Talk with your doctor or pharmacist—they can assess your specific drugs and blood pressure to decide if it's safe.
What side effects should I watch for?
Diarrhea, gas, and general stomach upset are the most common. A small number of people at higher doses also reported nausea, abdominal pain, or constipation. These are mild, but if they don't settle or get worse, stop and check with your pharmacist.
Does pomegranate actually help with high blood pressure?
The evidence says it's possibly effective—meaning some research shows it can modestly lower pressure, but it's not a proven replacement for medication. If you're interested, discuss it with your doctor as part of your overall plan, not as a solo treatment.
Is this safe to take while I'm pregnant or breastfeeding?
The data rates it possibly safe, but there isn't a lot of information on how concentrated supplements affect pregnancy and nursing. Talk with your doctor or pharmacist before starting if you're pregnant or breastfeeding—they can give you personalized advice based on your situation.
Will this help my cholesterol or blood sugar?
The research doesn't support it for either one. Pomegranate is rated possibly ineffective for cholesterol and diabetes, so it's not the right choice if those are your main goals.
