HelloPharmacist Scorecard of Oleuropein by Roex

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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: olive leaf extract, a concentrated form of compounds from olive leaves. The capsule also includes inactive ingredients (rice flour, hydroxypropyl methylcellulose, magnesium stearate, and silica) that serve as a filler, capsule material, and flow agent.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Olive's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: immune support and cardiovascular health.
  • We looked for evidence on: Exercise-induced respiratory infections, Influenza, Metabolic syndrome, antioxidant support, oxidative stress.
  • The closest evidence on file: Olive is rated "Insufficient Reliable Evidence To Rate" for Exercise-induced respiratory infections (Natural Medicines).
  • Also on file: Olive is rated "Insufficient Reliable Evidence To Rate" for Influenza, Metabolic syndrome.

The evidence for olive leaf extract is not established in the data we hold. It has been studied for osteoporosis, upset stomach (dyspepsia), exercise-related respiratory infections, shingles, flu, and osteoarthritis, but in each case the evidence is insufficient to rate whether it works.

You'd want to talk with your doctor about whether this ingredient is right for what you're hoping it will do.

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.

Olive leaf extract appears to be well tolerated overall. In clinical trials, the most common side effects were headache and stomach discomfort; one person reported skin and acne.

Olive oil and olives as foods are very safe, but concentrated supplements like this one are less studied — the safety data is limited. If you're pregnant or breastfeeding, there isn't enough information on file to say whether it's appropriate, so check with your doctor or pharmacist before taking it.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. No medication interactions are currently documented, and safety information is well characterized.

Roex Oleuropein is a single-ingredient supplement with no documented drug interactions. The evidence for its effectiveness isn't established yet, and because concentrated olive leaf supplements are less studied than the food forms, it's worth running by your doctor or pharmacist before you start — especially if you're pregnant, breastfeeding, or have questions about whether it's right for your situation.

Oleuropein by Roex: Common Questions

Does Oleuropein by Roex interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Oleuropein. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Oleuropein contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
What does olive leaf extract actually do?
The evidence isn't clear yet. It's been studied for bone health, upset stomach, respiratory infections, shingles, flu, and joint pain, but the data we hold isn't strong enough to say whether it works for any of those. Your doctor or pharmacist can help you decide if it makes sense for your needs.
Is this safe to take?
Olive leaf extract seems to be well tolerated — the most common side effects in trials were headache and stomach discomfort. However, concentrated olive leaf supplements are less studied than olive oil and olives as foods, so safety data is limited. Talk with your doctor before starting, especially if you have a health condition or take other supplements.
Can I take this while pregnant or breastfeeding?
There isn't enough information on file to know whether it's safe during pregnancy or breastfeeding. Check with your doctor or pharmacist for personalized advice before taking it.
Does this interact with my medications?
No interactions are documented in our data for olive leaf extract. You're welcome to search your specific medications on this page to be sure, but based on what we hold, there are no known drug interactions.
What's in the capsule besides the olive leaf extract?
The capsule contains rice flour, hydroxypropyl methylcellulose (a capsule material), magnesium stearate, and silica — all inactive ingredients that help hold the product together and allow it to break down in your stomach.
