HelloPharmacist Scorecard of Olive Leaf by Herb Stop
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
Low disclosure
This product contains one active ingredient: olive leaf extract. The liquid also includes grape alcohol and water as inactive ingredients.
Does it work?
Not established
The evidence we hold on olive leaf extract doesn't establish its effectiveness for any of the conditions it's marketed for—osteoporosis, upset stomach (dyspepsia), exercise-induced respiratory infections, shingles, flu, or osteoarthritis all show insufficient reliable evidence to rate. That means the studies aren't there yet, not that it doesn't work.
How safe is it?
Well-documented data
Olive leaf extract appears to be well tolerated overall. In clinical trials, the most common side effects reported were headache and stomach discomfort; one person reported skin and acne.
Keep in mind that while olives and olive oil as foods are very safe, concentrated supplements like this one are less studied, so the safety profile isn't as well understood. If you're allergic to olive tree pollen, you may want to be cautious.
There isn't enough data on file about the safety of concentrated olive leaf during pregnancy or breastfeeding to know either way—talk with your doctor or pharmacist for personalized advice if you're pregnant, planning pregnancy, or nursing.
Meds to double-check
No known interactions
No interactions are documented in our data for olive leaf extract. Still, run your medications through the checker on this page or confirm with your own doctor or pharmacist before adding this supplement to your routine.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. No medication interactions are currently documented, and safety information is well characterized.
Olive Leaf by Herb Stop is generally well tolerated, but we don't have reliable evidence it works for the conditions listed on the label. Because concentrated olive leaf supplements are less studied than the food forms, it's worth clearing it with your doctor or pharmacist before you start, especially if you're taking other medications or have health conditions.
