HelloPharmacist Scorecard of Olive Leaf Extract by Puritan's Pride

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 leaves have been used traditionally, and the extract concentrates compounds from the leaf.

The capsule itself is made from vegetable cellulose and gelatin, which are standard inactive ingredients (fillers and capsule material).

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 is not strong enough to rate olive leaf extract for any of the conditions it's marketed for — osteoporosis, upset stomach (dyspepsia), respiratory infections from exercise, shingles, flu, or osteoarthritis. That means we don't have reliable data saying it works or doesn't work; the research just isn't there yet or isn't solid enough to draw a conclusion.

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. Olive leaf extract in supplement form is less well studied, and concentrated supplements aren't as reassuring as the whole food.

Most people who take it seem to tolerate it well. The most common side effects reported in trials were headache and stomach discomfort.

One person in a trial reported skin problems and acne. If you have seasonal allergies to tree pollen, keep in mind that olive pollen can trigger respiratory allergy.

We don't have enough data on olive leaf extract in pregnancy or lactation to say whether it's safe. Talk with your doctor or pharmacist about whether it's right for you if you're pregnant or breastfeeding.

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. That said, run your exact medications through the search tool on this page before you start to make sure.

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, but the evidence that it actually works for any particular condition is too weak to rely on. Because the safety of concentrated supplements is less certain than whole olives or olive oil, get the okay from your own doctor or pharmacist before you start — especially if you're pregnant, breastfeeding, or have seasonal pollen allergies.

Olive Leaf Extract by Puritan's Pride: Common Questions

Does Olive Leaf Extract by Puritan's Pride 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.
Does olive leaf extract actually work for any of these conditions?
The evidence we hold is not strong enough to say it works for osteoporosis, upset stomach, exercise-related respiratory infections, shingles, flu, or osteoarthritis. We need better research to know.
What side effects might I experience?
Most people tolerate it well. The most common reported side effects are headache and stomach discomfort. One person in a trial reported skin problems and acne. If you're allergic to tree pollen, olive pollen can trigger respiratory symptoms.
Is this safe if I eat olives or olive oil already?
Olives and olive oil as food are very safe. This product is a concentrated supplement, which is much less studied. It's a different safety picture, so check with your doctor or pharmacist before adding it.
Can I take this if I'm pregnant or breastfeeding?
We don't have enough safety data to say. Talk with your doctor or pharmacist about whether it's appropriate for you in pregnancy or while nursing.
