HelloPharmacist Scorecard of Olive Leaf Extract 500 mg 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 at 500 mg per capsule. The extract comes from the leaves of the olive plant and has been used traditionally for various purposes.

The capsule also contains inactive ingredients (cellulose, silica, and magnesium stearate) that help hold it 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 research we have is insufficient to rate it for osteoporosis, indigestion (dyspepsia), exercise-induced respiratory infections, shingles (herpes zoster), flu, or osteoarthritis.

If you're considering this supplement for one of these reasons, talk with your doctor about what the current evidence 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 leaf extract appears to be well tolerated overall. The most common side effects reported in trials were headache and stomach discomfort.

One patient reported skin problems and acne, and the pollen can trigger seasonal respiratory allergies in sensitive people. The caution here is that while olives and olive oil as foods are very safe, concentrated supplements like this one are less studied, so approval from your doctor before use is a good idea.

Olive Leaf Extract 500 mg by Puritan's Pride: Common Questions

Does Olive Leaf Extract 500 mg by Puritan's Pride interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Olive Leaf Extract 500 mg. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Olive Leaf Extract 500 mg 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 ones we see most often. One person reported skin problems and acne. Overall, the supplement seems to be well tolerated.
Does olive leaf extract actually work?
The evidence isn't strong enough to say. We don't have reliable data for osteoporosis, indigestion, respiratory infections, shingles, flu, or osteoarthritis. If you're thinking about it for one of those reasons, your doctor can help you weigh what we do and don't know.
Is this safe to take long-term?
Olive oil and olives as foods are very safe, but concentrated supplements like this one haven't been studied as thoroughly. Your doctor or pharmacist can help you decide if it's right for you.
Can I use this if I have seasonal allergies?
Olive tree pollen can trigger allergies in some people, so if you're sensitive to pollen, let your pharmacist know before you start.
What's actually in the capsule besides the extract?
The capsule contains cellulose, silica, and magnesium stearate — these are inactive ingredients that help make the capsule work but aren't the active part.
