HelloPharmacist Scorecard of Olive Leaf Extract 500 mg by Herbal Secrets

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. Olive leaf has been used in herbal medicine for centuries, though modern research is still building.

The capsules also include rice flour and vegetable cellulose as inactive ingredients to hold everything together.

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: antimicrobial support combating bacteria and viruses.
  • We looked for evidence on: Exercise-induced respiratory infections, Herpes zoster (shingles), Influenza, bacterial infection, viral infection, immune support.
  • 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 Herpes zoster (shingles), Influenza.

The evidence on olive leaf extract is still developing. Our data shows insufficient reliable evidence to rate its use for osteoporosis, indigestion (dyspepsia), exercise-related respiratory infections, shingles (herpes zoster), flu, or osteoarthritis.

That doesn't mean it doesn't work — it means larger, well-designed studies are needed to know for sure. If you're considering it for any of these reasons, talk it through with your doctor or pharmacist first.

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 seems to be well tolerated overall. The most common side effects reported in trials were headache and stomach discomfort.

One person in a trial reported skin problems and acne. Keep in mind that while olives and olive oil as foods are very safe, concentrated supplements like this one are less studied, so the long-term safety picture isn't fully clear yet.

If you have a known allergy to olive tree pollen or seasonal respiratory allergies, be aware that olive tree pollen can trigger symptoms.

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. This does not mean interactions cannot occur — it means the research available to us hasn't identified any yet.

Before you start, confirm with your own doctor or pharmacist that it won't interfere with your specific 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.

Olive Leaf Extract 500 mg might appeal to you if you're interested in traditional herbal support, but evidence for specific health benefits is not yet established in the data we hold. The supplement appears generally well tolerated, though concentrated forms are less studied than the food forms most of us are familiar with.

Talk with your doctor or pharmacist about whether it makes sense for your situation and what to watch for.

Olive Leaf Extract 500 mg by Herbal Secrets: Common Questions

Does Olive Leaf Extract 500 mg by Herbal Secrets 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's the difference between olive leaf extract and olive oil?
Olive oil comes from the fruit, while olive leaf extract is concentrated from the leaves of the olive tree. Olive oil and olives as food are very safe, but this supplement is a concentrated form that's less studied, so it's worth checking with your doctor before starting.
What side effects should I expect?
Most people tolerate olive leaf extract well. The most common reported side effects were 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 allergies, be aware that olive pollen can trigger respiratory symptoms.
Does olive leaf extract actually work for any specific condition?
Our data shows insufficient reliable evidence to rate olive leaf extract for conditions like osteoporosis, indigestion, exercise-related respiratory infections, shingles, flu, or osteoarthritis. More research is needed to know whether it's effective.
Is it safe to take if I'm pregnant or breastfeeding?
We don't have enough data on file to know whether concentrated olive leaf supplements are safe during pregnancy or breastfeeding. Talk with your doctor or pharmacist before starting if you're pregnant, planning to become pregnant, or nursing.
Can I take this with my medications?
No interactions are documented in our data for olive leaf extract. That said, absence of documented interactions isn't a guarantee that none exist. Use the search tool on this page to check your specific medications, and let your doctor or pharmacist know you're considering this supplement.
