Olive Leaf Ingredients & Drug Interactions
What is this page for?

Around that, we add a pharmacist’s high-level view of the product as a whole — what’s inside, the evidence for its stated use, how transparent the label is, and what safety data exists — so you can see the full picture in one place. It’s educational information from our licensed clinical databases and the clinical staff at HelloPharmacist — not medical advice — and we don’t sell or endorse products. Our editorial policy

HelloPharmacist Scorecard of Olive Leaf by Mountain Meadow Herbs
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 liquid contains one active ingredient: olive leaf extract. In food form—olives and olive oil—this stuff has been eaten safely for centuries.
The extract is a more concentrated version, which is why the safety data around supplements made from it is thinner than what we know about the food itself. The liquid also contains vegetable glycerin, distilled water, and organic grain alcohol as inactive ingredients to preserve and deliver the extract.
Does it work?
Couldn't assess
The evidence we hold doesn't establish that olive leaf extract works for any condition we checked—including osteoporosis, upset stomach, exercise-related respiratory infections, shingles, flu, or osteoarthritis. Each of these showed insufficient reliable evidence to rate.
That doesn't mean it's ineffective; it means the research backing isn't strong enough yet to say either way.
How safe is it?
Well-documented data
Olive fruit and olive oil eaten as food are very safe. Olive leaf extract seems to be well tolerated in the trials we have, but concentrated supplements from olive haven't been studied as thoroughly as the food form.
The most common side effects reported are headache and stomach discomfort. One trial participant reported skin and acne.
People with seasonal pollen allergies to olive tree pollen should be aware. There isn't enough safety data to know how concentrated olive leaf supplements behave in pregnancy or while breastfeeding—the facts on file don't address it.
Talk with your doctor or pharmacist before using this product if you're pregnant, nursing, or planning to be, so you can weigh what's known and what isn't.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredients we could check. That said, run your exact medications through the search tool on this page to be thorough, and clear the product with your own 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 extract is generally well tolerated based on the trial data we have, but it's less studied than plain olives or olive oil. The evidence doesn't yet show it works for the conditions we checked.
If you're interested in trying it, mention it to your doctor or pharmacist first—especially if you're pregnant, breastfeeding, or have seasonal pollen allergies—so they can give you personalized advice.
