HelloPharmacist Scorecard of Olive Leaf by Pure
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 2 active ingredients: oleuropein and olive leaf 20% extract. The extract is a concentrated form derived from olive leaves.
The capsules themselves are made from gelatin.
Does it work?
Not established
The evidence for olive leaf extract isn't established in the data we hold. The facts show insufficient reliable evidence to rate it for osteoporosis, upset stomach (dyspepsia), exercise-related respiratory infections, shingles, flu, and osteoarthritis.
If you're thinking about it for one of these reasons, it's worth discussing with your doctor what the current research actually supports.
How safe is it?
Well-documented data
Olive as food and oil is very safe, but concentrated supplements like this one are less well studied — so the safety profile of the extract itself isn't fully known. When taken orally in typical amounts, olive leaf extract appears to be well tolerated overall.
The most common side effects reported are headache and stomach discomfort; one person in a trial reported skin problems and acne. Keep in mind that olive tree pollen can trigger seasonal respiratory allergies if you're sensitive to it.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredient we could check. We couldn't verify oleuropein, so ask your pharmacist to confirm if you're on any medications.
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.
Pure Olive Leaf is generally well tolerated and has no documented medication interactions for the ingredient we could check. The evidence for what it actually does isn't established in the data we hold.
Because concentrated olive supplements are less studied than the food form, it's worth talking with your doctor or pharmacist before starting — especially if you're pregnant, nursing, or have any health concerns.
