HelloPharmacist Scorecard of Olive Leaf Extract by Designs for Health

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.

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. It's made from the leaves of the olive plant and has been used traditionally for various purposes.

The capsule also contains microcrystalline cellulose and vegetable stearate as inactive ingredients to help form and stabilize the supplement.

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. We have insufficient reliable evidence to rate it for osteoporosis, indigestion (dyspepsia), exercise-related respiratory infections, shingles (herpes zoster), influenza, or osteoarthritis.

That doesn't mean it doesn't work—it means larger, well-designed studies haven't settled the question yet.

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. In trials, the most common side effects were headache and stomach discomfort.

One patient reported skin and acne, and the supplement may trigger seasonal respiratory allergy if you're sensitive to olive tree pollen. Here's the catch: olives and olive oil as foods are very safe, but concentrated supplements are less studied.

The safety data we have is limited compared to what we know about olive oil in your kitchen. Talk with your doctor or pharmacist about whether this product is right for you before you start.

Why this rating?

No interactions are documented in our data for the ingredient we could check. Still, confirm with your own doctor or pharmacist before starting, especially if you're on any regular medications.

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 by Designs for Health has no documented interactions with medications. If you're interested in trying it, the evidence for its benefits isn't yet established in our data.

The supplement is generally well tolerated, but because concentrated forms are less studied than olive oil as food, it's worth confirming with your own doctor or pharmacist that it's a good fit for your situation.

Olive Leaf Extract by Designs for Health: Common Questions

Does Olive Leaf Extract by Designs for Health 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 is olive leaf extract used for?
Olive leaf extract has been used traditionally for several purposes—including bone health, digestion, respiratory health during exercise, shingles, flu, and joint health—but the evidence to support these uses isn't established in the data we hold. You'd want to talk with your doctor about whether it's likely to help with your specific situation.
What are the side effects?
Most people tolerate olive leaf extract well. The most common side effects in trials were headache and stomach discomfort. One person reported skin and acne. If you're sensitive to olive tree pollen, this supplement may trigger seasonal respiratory allergies.
Is this safe to take long-term?
Olive as food and oil is very safe, but concentrated supplements like this one are less studied over time. The safety data we hold is limited. Check with your doctor or pharmacist about long-term use before you start.
Can I take this if I'm pregnant or nursing?
We don't have safety data on file for olive leaf extract during pregnancy and breastfeeding. Talk with your doctor or pharmacist about whether it's right for you in these situations—they can weigh your individual needs against what we do and don't know.
Does this interact with my medications?
No interactions are documented in our data for olive leaf extract. That doesn't mean interactions can't exist—it means we haven't found them yet. Run your exact medications through the search tool on this page or confirm with your own pharmacist before you start.
