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.

From our pharmacy team — supplement deep dive

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

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
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Olive product and its label doesn't state a use — see Olive's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

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.

The evidence, ingredient by ingredient Olive

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

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.

Known Interaction Concern · database check
No known interactions

No medication interactions are currently documented for the matched ingredients — that isn't a guarantee none exist.

Why this rating?
  • None of the 1 matched ingredient has a documented medication interaction on file.

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.

Olive Leaf Extract by Wonder Laboratories: Common Questions

Does Olive Leaf Extract by Wonder Laboratories interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Olive Leaf Extract. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Olive Leaf Extract contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
What's the difference between this supplement and olive oil or olives I eat?
Olive oil and olives as food are very safe and studied extensively. This is a concentrated supplement form, which means it's a much higher dose of olive leaf compounds than you'd get from eating. Concentrated supplements haven't been studied as thoroughly.
What side effects have been reported?
In clinical trials, olive leaf extract was generally well tolerated. The most common side effects were headache and stomach discomfort. One person reported skin issues and acne. If you have seasonal allergies to olive pollen, you may want to be cautious.
Does this actually work for colds, the flu, or shingles?
We don't have evidence strong enough to say whether it works for those or any other condition it's marketed for. The studies we hold are rated as having insufficient reliable evidence—meaning the research so far hasn't been conclusive either way.
Is it safe to take while pregnant or breastfeeding?
We don't have enough safety information on file about olive leaf extract during pregnancy or breastfeeding. Talk with your doctor or pharmacist—they can weigh the latest evidence and your personal situation to give you the best guidance.
Will this interfere with my medications?
No interactions are documented in our data for olive leaf extract. That said, absence of documented interactions isn't a guarantee none exist. If you're on any prescription drugs, mention this supplement to your doctor or pharmacist, or use the medication checker on this page.
