HelloPharmacist Scorecard of Pomegranate Extract 500 mg by Source Naturals

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.
  • “Pomegranate fruit extract” is listed as a grouped ingredient — the label gives one combined amount (1 Gram(s)) without saying how much of each component you get.

This product contains one active ingredient: ellagic acid, a compound found in pomegranate. Ellagic acid is extracted from the pomegranate fruit and made into a concentrated supplement at 500 mg per tablet.

The rest of the tablet is made up of inactive ingredients — microcrystalline cellulose, silicified microcrystalline cellulose, stearic acid, modified cellulose gum, and silica — which help give the tablet its form and stability.

Does it work?

Strong 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
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Antioxidant and DNA protection.
  • We looked for evidence on: Atherosclerosis, Cancer, Coronary heart disease (CHD), Diabetes, Hyperlipidemia, Hypertension — and 4 related terms.
  • The strongest evidence on file: Black Psyllium is rated "Likely Effective" for Coronary heart disease (CHD) (Natural Medicines).
  • Also on file: Black Psyllium is rated "Insufficient Reliable Evidence To Rate" for Cancer, Nonalcoholic fatty liver disease (NAFLD), Diabetes, Hypertension.
  • Also on file: Ellagic Acid is rated "Insufficient Reliable Evidence To Rate" for Bladder cancer, Prostate cancer.

The evidence for ellagic acid's effectiveness is currently insufficient to rate. While this supplement is studied for bladder cancer, prostate cancer, cognitive function, diabetes, melasma, and polycystic ovary syndrome (PCOS), we don't have reliable evidence yet to say whether it actually works for any of these purposes.

That doesn't mean it's ineffective — it means more research is needed to know.

The evidence, ingredient by ingredient Black Psyllium Pomegranate Ellagic Acid

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Ellagic acid is generally considered safe in the amounts found in foods, but concentrated supplements like this one haven't been well studied in humans. The safety data on supplement doses is limited, so it's best to avoid high-dose concentrated supplements unless you've talked it over with your doctor or pharmacist.

In one clinical trial, a combination containing ellagic acid and graviola caused nausea and diarrhea in a small number of participants, though it's unclear whether ellagic acid alone was responsible. There is currently not enough safety information on file for ellagic acid use in pregnancy or lactation — talk with your doctor or pharmacist if you're pregnant, planning to become pregnant, or breastfeeding.

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?
  • 2 of the 2 matched ingredients can interact with medications — Black Psyllium, Ellagic Acid.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications; heart-rhythm medications; lithium.
  • For scale: 2,054 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 product, double-check any antidiabetes medications you're on — metformin, insulin, and similar drugs — with your doctor or pharmacist. Ellagic acid can lower blood sugar levels, and combining it with diabetes medication might lower your blood sugar too much.

The bottom line

Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

If you take diabetes medication, this product isn't something to start without checking first — the ellagic acid in it may lower your blood sugar further, raising the risk of low blood sugar. If you don't take diabetes drugs, you should still know that concentrated ellagic acid supplements aren't well studied in humans.

Have a conversation with your doctor or pharmacist before starting this product, especially if you're on any medications or managing a health condition.

Each ingredient & the kinds of drugs it affects

For each ingredient in Pomegranate Extract 500 mg with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Dietary Fiber7 drug types · 2,025 drugs

Carbamazepine (Tegretol)

Theoretically, black psyllium might reduce the effects of carbamazepine and increase the risk for convulsions.
Theoretically, black psyllium might reduce carbamazepine absorption. A preliminary study using blond psyllium reported decreased carbamazepine bioavailability due to binding of the drug to psyllium, as well as reduction of available fluid in the gut for dissolution of the drug. This interaction may also occur with black psyllium.

Likelihood Probable Evidence D
Lithium

Theoretically, taking black psyllium at the same time as lithium might reduce lithium absorption.
The fiber in black psyllium might reduce lithium absorption and plasma levels. Some case reports describe a reduction in plasma lithium levels with concomitant administration of blond psyllium. This was reversed when psyllium was stopped. This interaction may also occur with black psyllium.

Likelihood Probable Evidence D
Metformin (Glucophage)

Theoretically, black psyllium might increase the therapeutic and adverse effects of metformin.
Animal research shows that concurrent consumption of blond psyllium with metformin slows and increases the absorption of metformin. This interaction may also occur with black psyllium. To avoid changes in absorption, take psyllium 30-60 minutes after metformin.

Likelihood Possible Evidence D
Olanzapine (Zyprexa)

Theoretically, taking black psyllium at the same time as olanzapine might reduce olanzapine absorption.
The fiber in black psyllium might decrease the absorption of olanzapine. A single case report describes a reduction in the effectiveness of olanzapine when it was concomitantly administered with an unspecified type of psyllium 3 grams orally twice daily. This effect was reversed when psyllium was stopped.

Likelihood Possible Evidence D
Digoxin (Lanoxin)

Theoretically, taking black psyllium at the same time as digoxin might reduce digoxin absorption and decrease digoxin levels.
Psyllium might bind digoxin in the gut. However, some clinical evidence suggests that psyllium does not impact digoxin absorption.

Likelihood Unlikely Evidence B
Ethinyl Estradiol

Theoretically, taking black psyllium at the same time as ethinyl estradiol might alter levels of estradiol.
Concurrent use of blond psyllium with ethinyl estradiol results in a slight increase in the extent of ethinyl estradiol absorption and a slower rate of absorption. This is unlikely to be clinically significant.

Likelihood Unlikely Evidence D
Oral Drugs

Theoretically, psyllium might increase, decrease, or have no effect on the absorption of oral drugs.
Psyllium seems to have variable effects on drug absorption. To avoid changes in absorption, take psyllium 30-60 minutes after oral medications. Animal research shows that blond psyllium delays and increases the absorption of metformin and ethinyl estradiol. Case reports and animal research suggest that blond psyllium might reduce absorption of lithium, digoxin, olanzapine, and carbamazepine. Finally, some pharmacokinetic studies show that psyllium does not affect the absorption of levothyroxine or warfarin. Although many of these studies evaluated blond psyllium, the fiber content in black psyllium may have similar effects.

Likelihood Possible Evidence B
Dietary Fiber full monograph & interactions

Pomegranate fruit extract9 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 Extract 500 mg by Source Naturals: Common Questions

Does Pomegranate Extract 500 mg by Source Naturals interact with any medications?
Yes. Based on its ingredients, Pomegranate Extract 500 mg has a known interaction with 2,124 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Pomegranate Extract 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.
Does pomegranate extract actually work for diabetes?
The evidence isn't established yet. While ellagic acid, the active ingredient in pomegranate extract, is being studied for type 2 diabetes, we don't have reliable evidence to say whether it actually helps. What we do know is that it can lower blood sugar in people already on diabetes medication — which is why you need to be careful if you take those drugs.
Will this supplement lower my blood sugar if I'm on metformin or insulin?
It might. Research shows ellagic acid can reduce blood sugar levels in people with type 2 diabetes who are on stable doses of these medications. That's why there's a moderate risk of your blood sugar dropping too low — talk to your doctor or pharmacist about whether you should take this supplement and whether your blood sugar needs monitoring.
What are the side effects?
In one clinical trial, a combination product containing ellagic acid and graviola caused nausea and diarrhea in a few participants, but it's not clear if ellagic acid alone was responsible. Concentrated ellagic acid supplements aren't well studied in humans, so other side effects aren't well known.
Is it safe to take while pregnant or breastfeeding?
There isn't enough safety information to know either way. If you're pregnant, planning to become pregnant, or breastfeeding, talk with your doctor or pharmacist before taking this supplement to get personalized advice.
What is ellagic acid and why is it in this product?
Ellagic acid is a naturally occurring compound found in pomegranate and other fruits. It's concentrated and put into supplements because it's being studied for potential health benefits, though the evidence so far is insufficient to confirm whether it actually works for any specific condition.
Is this product just pomegranate fruit, or is there something more in it?
It's concentrated pomegranate fruit extract — specifically standardized to ellagic acid at 500 mg per tablet. The tablet also contains several inactive ingredients (microcrystalline cellulose, stearic acid, and others) that help hold it together and keep it stable on the shelf.
