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 (Olea europaea) young shoot extract, a concentrated form of compounds from the olive plant's early growth. The remaining ingredients are glycerin, ethanol, and purified water — these are inactive ingredients that help deliver and preserve the extract.

Olive as a food and oil has been part of human diets for millennia, but this product is a concentrated supplement form, which means the dose and processing are quite different from what you'd get from eating olives or drizzling 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 for olive young shoot extract isn't established in the data we hold. The product is marketed for osteoporosis, indigestion (dyspepsia), exercise-related respiratory infections, shingles, flu, and osteoarthritis, but our effectiveness ratings show insufficient reliable evidence to rate it for any of these uses.

That doesn't mean it doesn't work — it means the clinical trial evidence we have access to isn't strong enough yet to make a confident claim either way.

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 well tolerated. Olive leaf extract (a related form) also appears to be well tolerated in clinical trials.

The most common side effects reported are headache and stomach discomfort. One person in a trial reported skin problems and acne.

Additionally, olive tree pollen can trigger seasonal respiratory allergies in sensitive people. The main caution here is that concentrated olive supplements haven't been studied as thoroughly as the olive oil and olives you might eat.

The safety data for pregnancy and lactation are not on file for this ingredient, so talk with your doctor or pharmacist if you're pregnant, planning to become pregnant, or breastfeeding before taking it.

Meds to double-check

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 this ingredient. That said, because concentrated olive supplements are less studied than olive oil or whole olives, and because some olive compounds may affect blood pressure or blood sugar, check your exact medications 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.

UNDA Gemmo Olea Europaea is a concentrated olive extract that appears generally well tolerated based on the limited evidence we have. However, because it's a concentrated supplement rather than a food form, and because the evidence for its claimed benefits is insufficient, it's worth discussing with your own doctor or pharmacist before starting — especially if you're pregnant, breastfeeding, or take medications that affect blood pressure, blood sugar, or clotting.

Olea Europaea by UNDA Gemmo: Common Questions

Does Olea Europaea by UNDA Gemmo interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Olea Europaea. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Olea Europaea 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.
Is olive extract safe to take every day?
Olive leaf extract appears well tolerated in clinical trials, with only minor side effects like headache and stomach discomfort reported. That said, the long-term safety of concentrated olive supplements isn't as well known as that of olive oil or olives as food. Talk with your doctor or pharmacist about whether daily use is right for you.
Can I take this if I'm pregnant or breastfeeding?
We don't have safety data on file for this ingredient during pregnancy or lactation. Because the safety of concentrated olive supplements in these situations isn't well established, talk with your doctor or pharmacist before taking it if you're pregnant, planning to become pregnant, or breastfeeding.
Does this really help with arthritis or bone health?
The evidence we hold shows insufficient reliable evidence to rate olive extract for osteoarthritis or osteoporosis. That means clinical trials haven't given us enough reliable data to say it works — but it also doesn't mean it doesn't. Your doctor can discuss whether it might fit into your care plan.
What are the side effects?
The most common side effects in trials were headache and stomach discomfort. One person reported skin problems and acne. If you have seasonal allergies to pollen, olive tree pollen may trigger symptoms. Stop and contact your doctor if you notice any unusual effects.
Why is this a concentrate instead of regular olive oil?
This is a gemmotherapy extract — it pulls compounds from the young shoots of the olive plant at a specific growth stage. It's a different form from cooking oil or table olives, which is why we have fewer safety studies on it and why concentrated supplements are handled differently.
