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 a single active ingredient: olive leaf extract. The capsules also include vegetable cellulose and vegetable magnesium stearate as inactive ingredients (binders and capsule material).
Olive leaf extract is a concentrated form of compounds from the olive plant. It's different from olive oil or table olives you might eat—this is a supplement, and the safety profile of concentrated forms is less well studied than the food versions.
Does it work?
Couldn't assess
The evidence we hold doesn't establish that olive leaf extract is effective for any of the uses it's commonly promoted for. The conditions studied—osteoporosis, dyspepsia (indigestion), exercise-induced respiratory infections, herpes zoster (shingles), influenza, and osteoarthritis—all carry a rating of insufficient reliable evidence.
That means the research so far hasn't been strong enough to say whether it works or doesn't.
How safe is it?
Well-documented data
Olive leaf extract appears to be well tolerated in the trials we have data for. The most commonly reported side effects were mild: headache and stomach discomfort.
One person reported skin issues and acne. People with seasonal allergies to olive tree pollen may want to be cautious.
The main caution here is that concentrated olive leaf supplements are less studied than olives and olive oil as food. The safety data we hold advises caution with concentrated supplements unless your doctor approves.
There isn't enough information on file about this ingredient's safety in pregnancy or while breastfeeding—talk with your doctor or pharmacist for personalized guidance if either applies to you.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredients we could check. Still, it's worth confirming with your own doctor or pharmacist before starting, especially since concentrated olive leaf supplements are less well studied than the food forms.
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.
Olive Leaf Extract by Wonder Laboratories is generally well tolerated, but we don't have evidence it works for the conditions it's often marketed for. If you're curious about it for a specific health goal, talk it over with your doctor or pharmacist to see if it fits your situation.
Because concentrated supplements are less studied than olive oil or olives in your diet, getting their sign-off first is a good idea.
