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.
What’s inside
Full disclosure
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
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
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.
Meds to double-check
No known interactions
No interactions are documented in our data for the olive leaf extract in this product.
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.
