HelloPharmacist Scorecard of Olive Leaf Glycerite by NOW
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 has one active ingredient: olive leaf extract. Olive leaf has been used traditionally and studied for various purposes, though the evidence remains limited for most of them.
The extract is delivered in a glycerite base — a liquid form made with glycerin and water — which makes it easy to take by mouth.
Does it work?
Couldn't assess
The evidence we hold doesn't establish that olive leaf extract works for any of the conditions it's marketed for — osteoporosis, upset stomach (dyspepsia), exercise-related respiratory infections, shingles, flu, or osteoarthritis. All six carry a rating of insufficient reliable evidence.
That doesn't mean it doesn't work; it means the research isn't there yet to say one way or the other.
How safe is it?
Well-documented data
Olive leaf extract is generally well tolerated in the trials we've reviewed. The most common complaints were headache and stomach discomfort.
One person reported acne and skin problems, and if you have seasonal allergies to olive tree pollen, this supplement could be a trigger. The caution here is important: olive oil and olives as food are very safe, but concentrated supplements like this one are less studied, so check with your doctor before starting if you're pregnant, nursing, or have any health conditions.
Meds to double-check
No known interactions
No interactions are documented for olive leaf extract in our data. Use the medication checker on this page to run your specific drugs through, but there's no known major interaction category to watch for.
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 curious about olive leaf and want to try it, the safety profile is reasonable — most people don't report problems. Just know the evidence for what it treats isn't solid yet.
Talk to your pharmacist before you start, especially if you're pregnant, nursing, or taking other medications or supplements.
