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.
What’s inside
Full disclosure
This is a single-ingredient product: olive leaf extract in powder form at 18% concentration. There are no inactive fillers or other ingredients listed.
Olive leaf has a long history in traditional use, though modern science is still catching up on what it can do.
Does it work?
Couldn't assess
The evidence isn't established for any of the conditions this extract is marketed for. The data we hold shows insufficient reliable evidence to rate it for osteoporosis, stomach upset (dyspepsia), exercise-related respiratory infections, shingles, flu, and osteoarthritis.
That means studies are either absent, too small, or too mixed to draw firm conclusions — not that it doesn't work, just that we can't say based on what we know right now.
How safe is it?
Well-documented data
Olive leaf extract seems to be well tolerated overall. The most common side effects reported are headache and stomach discomfort.
One person in a trial reported skin problems and acne, though that's rare. Keep in mind that olive oil and whole olives as food are very safe, but concentrated supplements haven't been studied as thoroughly, so use caution — check with your doctor before starting if you have any health concerns.
If you're allergic to olive tree pollen, you may want to steer clear. There isn't enough data on file about using this during pregnancy or while breastfeeding.
Talk with your doctor or pharmacist for personalized advice if you're pregnant, planning to be, or nursing.
Meds to double-check
No known interactions
No interactions are documented in our data for olive leaf extract. That said, check your specific medications with the search tool on this page before you start — absence of documented interactions is not a guarantee none exist.
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.
If you're drawn to olive leaf extract and want to try it, this powder is generally well tolerated and has no documented interactions with medications. But the evidence for what it actually does isn't solid yet, and concentrated supplements aren't as well studied as the olive oil and olives you'd eat.
Chat with your doctor or pharmacist before you start, especially if you're pregnant, breastfeeding, or have any health conditions.
