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 one active ingredient: olive leaf extract, a concentrated form of compounds from the olive plant. The capsules also contain vegetable cellulose and vegetable magnesium stearate as inactive ingredients — common binders and flow agents that help hold the capsule together.

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 whether olive leaf extract works for any of the conditions listed on the label — osteoporosis, indigestion (dyspepsia), exercise-related respiratory infections, shingles, flu, or osteoarthritis. All of these carry a rating of insufficient reliable evidence to rate.

That means the research so far is too limited or mixed to say whether it's effective, not that it definitely doesn't work.

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 seems to be generally well tolerated in the studies we've reviewed. The most common adverse effects reported are headache and stomach discomfort.

One person in a trial reported acne and skin problems. If you're allergic to olive tree pollen or have seasonal respiratory allergies, be aware that exposure to olive pollen can trigger symptoms.

The safety data notes a caution: while olives and olive oil as everyday foods are very safe, concentrated supplements haven't been studied as thoroughly. We don't have pregnancy or breastfeeding information on file for this ingredient — talk with your doctor or pharmacist to weigh whether it's right for you if you're pregnant or nursing.

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.

If you're curious about olive leaf extract for one of these conditions, know that the evidence isn't solid yet — the research we have is too limited to say it works. It appears to be well tolerated, but concentrated supplements aren't as well studied as the olive oil and olives you'd eat as food.

Before you start, run your medications through the tool on this page, and talk it over with your own doctor or pharmacist.

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 are the most common side effects?
Headache and stomach discomfort are the side effects most often reported in trials. One person reported acne and skin problems. Most people tolerate it well.
Is this safe if I have seasonal allergies to pollen?
If you're allergic to olive tree pollen, be cautious — exposure to that pollen can trigger respiratory allergy symptoms. Talk with your pharmacist or doctor about whether this supplement is right for you.
Can I take this if I'm pregnant or breastfeeding?
We don't have safety data on file for olive leaf extract in pregnancy or breastfeeding. Talk with your doctor or pharmacist for personalized advice before you take it.
Does olive leaf extract actually work for arthritis, the flu, or shingles?
The evidence we hold is too limited to say. All of these uses — arthritis, flu, shingles, and the others on the label — carry a rating of insufficient reliable evidence, which means the research so far isn't solid enough to confirm they work.
Is this different from regular olive oil?
Yes. Olive oil and olives as foods are very safe, but this is a concentrated supplement extract. Concentrated forms haven't been studied as much, which is why we note a caution about safety.
