HelloPharmacist Scorecard of Standardized Olive Leaf by Nature's Way

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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains 2 active ingredients: olive and olive extract. Both come from the same plant source and are listed separately because they're processed differently — one is the whole fruit, the other a concentrated extract.

The capsule itself is made from plant material, with magnesium stearate and silica as inactive ingredients to help with manufacturing and flow.

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 and olive leaf extract isn't established in the data we hold. The product is marketed for osteoporosis, indigestion (dyspepsia), exercise-induced respiratory infections, shingles, flu, and osteoarthritis — but our records show insufficient reliable evidence to rate any of these uses.

That means the science behind these claims hasn't been settled yet in the sources we track.

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 fruit and olive oil as foods are very safe, but concentrated supplements like this one are less studied, so the safety profile isn't as well known. Most people tolerate olive leaf extract well.

The most common side effects reported in trials were headache and stomach discomfort. Very rarely, someone reported acne or skin changes.

If you're sensitive to olive tree pollen, be aware that seasonal respiratory allergy is possible. Because concentrated olive supplements are less researched than the food forms you eat, check with your doctor before starting if you have any health concerns.

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.

This might appeal to you if you're interested in olive's traditional uses and want to try a concentrated form. But know that the evidence for these specific health claims isn't strong yet.

If you take medications regularly or have a medical condition, run this by your pharmacist first — and talk to your doctor if you're pregnant, breastfeeding, or have concerns about concentrated supplement safety.
