HelloPharmacist Scorecard of Olive Leaf Extract by Wonder Laboratories
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. It's made from the leaves of the olive plant and has been used traditionally for various health purposes.
The capsules also contain vegetable cellulose and vegetable magnesium stearate as inactive ingredients to hold the supplement together.
Does it work?
Couldn't assess
The evidence we hold doesn't establish that olive leaf extract works for any of the conditions it's marketed for — osteoporosis, indigestion, exercise-induced respiratory infections, shingles, flu, or osteoarthritis. We rated all of these as insufficient reliable evidence to rate, which means the research either isn't there, isn't strong enough, or is too small to say it works.
If you're thinking about this for a specific condition, talk with your doctor about whether it makes sense for you.
How safe is it?
Well-documented data
Olive leaf extract seems to be generally well tolerated. The most common side effects reported in trials were headache and stomach discomfort.
One person in a trial reported skin and acne. Keep in mind that olive oil and olives as food are very safe, but concentrated supplements like this one are less studied, so the full safety picture isn't as clear.
If you have seasonal allergies to olive tree pollen, this supplement could potentially trigger symptoms.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredient we could check. That said, run your exact medications through the search tool on this page or confirm with your doctor or pharmacist before starting, since supplements can sometimes affect how drugs work in ways that haven't been formally studied.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. No medication interactions are currently documented, and safety information is well characterized.
This is a single-ingredient supplement with no documented interactions, but its effectiveness for any health condition isn't established in the data we hold. If you're curious about it for a specific reason, talk with your doctor or pharmacist first — they can help you decide whether it's right for you and whether it makes sense alongside anything else you're taking.
