HelloPharmacist Scorecard of Olive Leaf Extract by Pure Encapsulations

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 (Olea europaea) extract. It's a concentrated form of compounds from the olive plant, meant to deliver a higher dose than you'd get from eating olives or olive oil as food.

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 yet in the data we hold. The ingredient has been studied for osteoporosis, upset stomach, exercise-related respiratory infections, shingles, the flu, and osteoarthritis, but there isn't enough reliable evidence to rate how well it works for any of these.

If you're considering it for a specific condition, talk with your doctor about whether the research supports it for you.

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 fruit and olive oil as food are very safe. Olive leaf extract seems to be well tolerated overall, though concentrated supplements are less studied than the food forms.

The most common side effects reported are headache and stomach discomfort. One person in a trial reported skin problems and acne.

If you're allergic to olive tree pollen or have seasonal respiratory allergies, keep that in mind. We don't have safety data on file for this ingredient in pregnancy or breastfeeding.

Because concentrated supplements are less well studied than food-form olives, talk with your doctor or pharmacist about whether it's right for you during pregnancy or while nursing.

Olive Leaf Extract by Pure Encapsulations: Common Questions

Does Olive Leaf Extract by Pure Encapsulations 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 most commonly reported side effects. One person in a trial also reported skin problems and acne. Olive leaf extract seems to be well tolerated overall, but concentrated supplements haven't been as thoroughly studied as olive oil or olives as food.
Is it safe to use olive leaf extract if I have a pollen allergy?
Olive tree pollen can trigger seasonal respiratory allergies. If you're sensitive to pollen, mention this supplement to your doctor or pharmacist before starting it.
Can I use this while I'm pregnant or breastfeeding?
We don't have safety data on file for olive leaf extract during pregnancy or breastfeeding. Because concentrated supplements are less studied than food forms of olives, talk with your doctor or pharmacist about what's right for you.
Does olive leaf extract really work for the flu or shingles?
The evidence isn't established yet. Olive extract has been studied for both, but there isn't enough reliable evidence to say how well it works for either. Talk with your doctor about your specific situation.
Why is concentrated olive leaf extract different from olive oil I use in cooking?
Olive oil and olives as food are very safe because you eat them in typical amounts. This supplement is a concentrated extract, and concentrated supplements are less well studied. That's why it's worth checking with your doctor before you start.
