HelloPharmacist Scorecard of Olea25 Hydroxytyrosol by Longevity by Nature
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 has 2 active ingredients: olive and pomegranate extract. Olive is included for its polyphenol content, though the evidence for its effects on bone health, digestion, joint pain, and immunity is not yet reliable.
Pomegranate extract provides polyphenols as well and has some evidence supporting a modest effect on blood pressure. The capsule also contains hypromellose, a standard inactive ingredient.
Does it work?
Moderate evidence
The data we hold shows pomegranate extract is possibly effective for high blood pressure — it may modestly lower it — but possibly ineffective for cholesterol and blood sugar. Olive's effectiveness for osteoporosis, heartburn, respiratory infections after exercise, shingles, flu, and osteoarthritis is rated insufficient — the evidence isn't established yet.
Neither ingredient has solid evidence for the other conditions listed.
How safe is it?
Well-documented data
Both olive and pomegranate are well tolerated in typical food amounts. Pomegranate fruit, juice, extract, and seed oil are generally well tolerated, but pomegranate root, stem, and peel should not be taken in large amounts.
Olive leaf extract seems well tolerated, but concentrated olive supplements are less studied than the food itself. The most common side effects from pomegranate are mild — diarrhea and gas — though headache and stomach discomfort can occur with olive.
One person reported acne with olive leaf extract, and olive tree pollen can trigger seasonal allergies. Pomegranate is rated possibly safe in pregnancy and lactation; we hold no pregnancy or lactation data for olive.
Meds to double-check
Moderate interaction found
Double-check this product against blood thinners (especially warfarin), blood pressure medications (antihypertensive drugs and ACE inhibitors), drugs metabolized by the CYP2D6 liver enzyme, the cholesterol drug rosuvastatin, drugs metabolized by CYP2C9 and CYP3A4 enzymes, and the seizure medication carbamazepine. These are Moderate to Minor severity interactions.
We could not check olive for interactions.
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 take blood pressure meds, blood thinners, or certain cholesterol or seizure medications, check with your pharmacist before starting this product. The pomegranate extract needs to be screened against your prescriptions.
Olive and pomegranate are foods we eat, but these are concentrated supplements with less safety history — talk to your doctor or pharmacist to make sure it's right for you.

Olea25 Hydroxytyrosol by Longevity by Nature Drug Interactions
HelloPharmacist Interaction Report
Olea25 Hydroxytyrosol by Longevity by Nature contains pomegranate extract, which interacts with several medication types.
The most serious concern is with blood thinners like warfarin (Coumadin) — pomegranate may raise warfarin levels and increase bleeding risk, and stopping pomegranate juice suddenly could lower warfarin levels and reduce how well the drug works.
Read the full breakdown — every affected drug type, severity by severity
Pomegranate also interacts with blood pressure medications (antihypertensive drugs and ACE inhibitors like lisinopril) — it may lower blood pressure further and raise the risk of low blood pressure (hypotension). It can affect drugs broken down by your liver's CYP2D6 enzyme (a moderate concern), and theoretically may increase levels of the cholesterol drug rosuvastatin (Crestor), though this is rare.
Minor interactions are documented with drugs metabolized by CYP2C9 and CYP3A4 enzymes, and with the seizure medication carbamazepine (Tegretol).
Olive, the other active ingredient, was not checked — we hold no interaction data for it. Altogether, these interactions span 911 individual medications.

For each ingredient in Olea25 Hydroxytyrosol 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.
Pomegranate Extract
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.
Antihypertensive Drugs
Theoretically, taking pomegranate with antihypertensive drugs might increase the risk of hypotension.
Consuming pomegranate juice can modestly lower blood pressure.
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.
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.
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.
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.
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.
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.
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.
