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. Olive leaf extract is derived from the leaves of the olive plant and has been studied for a range of conditions.

The capsule also contains two inactive ingredients — cellulose and magnesium stearate — which are common binders and fillers used to hold the supplement 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 for olive leaf extract isn't established in the data we hold. The product has been studied for osteoporosis, upset stomach (dyspepsia), exercise-related respiratory infections, shingles, flu, and osteoarthritis, but in each case the evidence is insufficient to rate whether it works.

That doesn't mean it doesn't work — it means more or better studies are needed to say for certain.

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 as a food and olive oil are very safe, but concentrated supplements like this one are less studied. A small number of trial participants reported headache or stomach discomfort; one person reported skin and acne changes.

Olive tree pollen can trigger seasonal respiratory allergies in sensitive people. The safety of concentrated olive leaf supplements isn't well known, so your doctor's approval is a good idea before you start.

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 is generally well tolerated, and we've found no drug interactions documented for it. If you're interested in trying it, talk with your pharmacist or doctor first — especially since the evidence for what it actually does isn't solid yet, and concentrated supplements are less studied than whole olive products.
