HelloPharmacist Scorecard of Olive Leaf 375 mg by Dr. Clark Store

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 375 mg per capsule. The capsule shell itself is made from gelatin, an inactive ingredient that holds the extract 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: Supports immune function.
  • We looked for evidence on: Exercise-induced respiratory infections, Influenza, Common cold, Viral infections.
  • 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 Influenza.

The evidence on olive leaf for the conditions listed — osteoporosis, indigestion (dyspepsia), exercise-related respiratory infections, shingles, flu, and osteoarthritis — is insufficient to rate. We don't have reliable data showing whether it works for any of these uses.

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. When taken as a concentrated supplement, the safety picture is less clear — these aren't as well studied as the food forms you'd eat.

In clinical trials, olive leaf extract has been well tolerated overall, though some people reported headache or stomach discomfort. One person in a trial developed skin problems and acne.

If you're sensitive to tree pollen, note that olive tree pollen can trigger seasonal respiratory allergies. Talk with your doctor or pharmacist before starting concentrated olive supplements, especially if you have any health concerns.

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 olive leaf extract. That doesn't mean none exist — it means they haven't been flagged in the research we hold.

If you take any medications, it's still worth confirming with your doctor or pharmacist before you start.

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 is generally well tolerated, but the evidence for what it can do isn't established yet. The safety data we hold mainly covers it as food and oil, not as a concentrated supplement — that's still less studied.

If you're thinking about taking this, check in with your doctor or pharmacist first to make sure it fits your health picture.

Does Olive Leaf 375 mg by Dr. Clark Store interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Olive Leaf 375 mg. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Olive Leaf 375 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.

What is olive leaf extract supposed to do?

Is this safe to take long-term?
Olive as food and olive oil are very safe. Concentrated supplements like this one are less studied, so the long-term safety isn't as clear. Talk with your doctor or pharmacist about whether this is right for you.

In trials, olive leaf extract was well tolerated overall. The most common complaints were headache and stomach discomfort. One person reported skin problems and acne. If you're sensitive to tree pollen, olive tree pollen can trigger seasonal allergies.
