HelloPharmacist Scorecard of Olive Leaf Extract by Pure Encapsulations
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 (Olea europaea) extract. It comes in a vegetarian capsule with hypoallergenic plant fiber as an inactive ingredient.
Does it work?
Couldn't assess
The evidence for olive leaf extract is still being built. Our data shows insufficient reliable evidence to rate it for osteoporosis, indigestion (dyspepsia), exercise-induced respiratory infections, shingles (herpes zoster), influenza, or osteoarthritis.
That doesn't mean it doesn't work—it means the research isn't there yet to say one way or the other.
How safe is it?
Well-documented data
Olive leaf extract appears to be well tolerated overall. The most common side effects reported in trials are headache and stomach discomfort.
One person in a clinical trial reported skin problems and acne. Because olives and olive oil as foods are very safe but concentrated supplements are less studied, the safety profile of this extract isn't as well known as everyday olive oil.
Olive tree pollen can trigger seasonal respiratory allergies in people who are sensitive to it. The facts on file don't include pregnancy or breastfeeding safety data for this ingredient.
If you're pregnant, nursing, or planning to become pregnant, talk with your doctor or pharmacist about whether this product is right for you.
Meds to double-check
No known interactions
No interactions are documented in our data for the olive extract in this product. That said, run your exact medications through the checker on this page before you start, and confirm with your own doctor or pharmacist if you have any questions.
