HelloPharmacist Scorecard of Olive Leaf Liquid Extract Alcohol & Sugar-Free by Swanson Premium Brand
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, a concentrated form of compounds from the olive plant leaf. The liquid is sweetened with vegetable glycerin and contains gum arabic as a thickener, with purified water as the base.
Does it work?
Couldn't assess
The evidence for olive leaf extract isn't established in the data we hold. The product has been studied for osteoporosis, indigestion (dyspepsia), respiratory infections from exercise, shingles, flu, and osteoarthritis, but all of these carry a rating of insufficient reliable evidence to rate — meaning the data isn't strong enough to say whether it works for any of them.
How safe is it?
Well-documented data
Olive as a food and olive oil are very safe, but concentrated supplements like this one are less studied. Olive leaf extract itself seems to be well tolerated overall.
The most common side effects reported are headache and stomach discomfort. One person in a trial reported skin and acne.
If you're allergic to olive tree pollen or have seasonal respiratory allergies, this product may be a concern. Because the safety of concentrated olive supplements isn't well known, your doctor should approve it before you take it.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredient we checked. That said, run your medications through the search tool on this page or confirm with your pharmacist before adding this to your routine — it's always the safest move.
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.
This product may appeal to you if you're interested in olive leaf extract and want an alcohol- and sugar-free option. The evidence for its effectiveness isn't established yet, so it's most useful if you're exploring it on your own terms rather than expecting it to treat a specific condition.
Talk it over with your doctor or pharmacist before you start, especially if you have respiratory allergies or take medications.
