HelloPharmacist Scorecard of Olive Leaf by Vitabase
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.
What’s inside
Full disclosure
This product contains one active ingredient: olive leaf extract. Olive leaf has a long history in traditional medicine and food use, though the concentrated extract form is less studied than the whole fruit or oil you'd find in cooking.
The capsule itself is made from gelatin.
Does it work?
Couldn't assess
The evidence for olive leaf extract isn't established in the data we hold. It's been studied for osteoporosis, indigestion (dyspepsia), exercise-related respiratory infections, shingles, flu, and osteoarthritis — but across all these uses, the data shows insufficient reliable evidence to rate whether it actually works.
How safe is it?
Well-documented data
Olive fruit and olive oil as foods are very safe, but concentrated supplements like this one are much less studied. The safety of the extract in supplement form isn't well known, so talk with your doctor before starting unless you've used olive leaf extract before.
When it has been used in trials, olive leaf extract seems well tolerated overall. The most common side effects reported are headache and stomach discomfort.
One person reported acne. If you're sensitive to olive tree pollen, be aware that's a potential concern.
Stop and let your doctor know if you notice any unusual symptoms.
Meds to double-check
No known interactions
No interactions are documented in our data for olive leaf extract. That doesn't mean none exist — it means this ingredient hasn't been studied extensively for drug interactions.
Before you start, run your exact medications through the checker on this page and confirm with your doctor or pharmacist.
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 by Vitabase is a single-ingredient supplement made from olive leaf extract. It's generally well tolerated when used, but the evidence for its effectiveness isn't established, and concentrated supplements of this type aren't as well studied as the whole food forms.
If you're thinking about using it, check with your doctor or pharmacist first — especially if you take any medications or have allergies to olive tree pollen.
