HelloPharmacist Scorecard of Olive Leaf 18% Extract Powder by TerraVita Premium Collection

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 18% concentration in powder form. Olive leaf extract is derived from the leaves of the olive plant and is used in supplements to deliver compounds found in olives in a more concentrated way than you'd get from eating whole olives or using olive oil.

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 we hold for olive leaf extract doesn't establish it works for the conditions it's marketed for. The data we have rates it as having insufficient reliable evidence for osteoporosis, indigestion (dyspepsia), exercise-related respiratory infections, shingles, flu, and osteoarthritis.

That means the studies either don't exist, are too small, or don't yet show a clear benefit. If you're considering it for one of these reasons, talk with your doctor about what the current science 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 fruit and olive oil as everyday foods are very safe, but concentrated supplements like this one are less well studied. The most common side effects reported with olive leaf extract are headache and stomach discomfort.

One person in a trial reported skin problems and acne. Keep in mind that olive tree pollen can trigger seasonal allergies if you're sensitive to it.

Because safety data on the concentrated supplement form is limited, check with your doctor before starting, especially if you have any health concerns.

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 olive leaf extract. That said, concentrated supplements are less studied than food forms, so if you take any medications and want to be extra cautious, check with your doctor or pharmacist before starting.

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 18% Extract Powder is generally well tolerated, but the evidence it works for specific health conditions isn't established in our data. Because concentrated olive leaf extract is less researched than whole olives or olive oil, talk with your doctor or pharmacist before taking it — they can help you decide if it fits your situation.

Olive Leaf 18% Extract Powder by TerraVita Premium Collection: Common Questions

Does Olive Leaf 18% Extract Powder by TerraVita Premium Collection interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Olive Leaf 18% Extract Powder. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Olive Leaf 18% Extract Powder 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 most often reported. One person in a trial developed skin problems and acne. Most people tolerate it well, but if you notice any of these, stop and talk with your pharmacist.
Is this safe during pregnancy or breastfeeding?
We don't have enough safety data on this concentrated supplement form during pregnancy or breastfeeding to say either way. Talk with your doctor or midwife before using it if you're pregnant or nursing — they can give you personalized advice.
Does it actually work for the conditions it claims to help?
The evidence we hold doesn't establish that it works for osteoporosis, indigestion, exercise-related infections, shingles, flu, or osteoarthritis. We rate all of these as insufficient reliable evidence, which means we need better studies to know if it helps.
Why is concentrated olive leaf extract riskier than olive oil?
Olives and olive oil as food are very safe because we've eaten them for thousands of years. Concentrated supplements are a much newer way to use the plant, and they're simply not as well studied. That's why extra caution is smart.
Could this trigger an allergic reaction if I'm sensitive to pollen?
Olive tree pollen can cause seasonal allergies in people who are sensitive. If you have hay fever or pollen allergies, mention this product to your doctor before trying it.
