HelloPharmacist Scorecard of Olive Leaf by Pure

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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains 2 active ingredients: oleuropein and olive leaf 20% extract. The extract is a concentrated form derived from olive leaves.

The capsules themselves are made from gelatin.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Olive's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Support immune system and cardiovascular health.
  • We looked for evidence on: Influenza, Exercise-induced respiratory infections, Metabolic syndrome, hypertension, hyperlipidemia, viral infection.
  • The closest evidence on file: Olive is rated "Insufficient Reliable Evidence To Rate" for Exercise-induced respiratory infections (Natural Medicines).
  • Also on file: Olive is rated "Insufficient Reliable Evidence To Rate" for Influenza, Metabolic syndrome.

The evidence for olive leaf extract isn't established in the data we hold. The facts show insufficient reliable evidence to rate it for osteoporosis, upset stomach (dyspepsia), exercise-related respiratory infections, shingles, flu, and osteoarthritis.

If you're thinking about it for one of these reasons, it's worth discussing with your doctor what the current research actually supports.

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 food and oil is very safe, but concentrated supplements like this one are less well studied — so the safety profile of the extract itself isn't fully known. When taken orally in typical amounts, olive leaf extract appears to be well tolerated overall.

The most common side effects reported are headache and stomach discomfort; one person in a trial reported skin problems and acne. Keep in mind that olive tree pollen can trigger seasonal respiratory allergies if you're sensitive to it.

Meds to double-check

No known interactions
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 ingredient we could check. We couldn't verify oleuropein, so ask your pharmacist to confirm if you're on any medications.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. No medication interactions are currently documented, and safety information is well characterized.

Pure Olive Leaf is generally well tolerated and has no documented medication interactions for the ingredient we could check. The evidence for what it actually does isn't established in the data we hold.

Because concentrated olive supplements are less studied than the food form, it's worth talking with your doctor or pharmacist before starting — especially if you're pregnant, nursing, or have any health concerns.
