HelloPharmacist Scorecard of Olive Leaf Extract 500 mg by Swanson
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 at 500 mg per capsule. Olive leaf has been studied for several conditions, including bone health, digestion, shingles, cold and flu, and joint health.
The capsule itself is made from gelatin and filled with microcrystalline cellulose, silica, and magnesium stearate — all inactive ingredients that help hold the supplement together.
Does it work?
Couldn't assess
The evidence for olive leaf extract is still developing. Our data shows insufficient reliable evidence to rate its use for osteoporosis, dyspepsia (indigestion), exercise-induced respiratory infections, herpes zoster (shingles), influenza (flu), and osteoarthritis.
That means research hasn't yet established whether it works for these purposes — not that it doesn't work, just that we don't have solid proof yet.
How safe is it?
Well-documented data
Olive leaf extract appears to be well tolerated overall. The most common side effects reported in trials were headache and stomach discomfort.
One person in a trial reported skin and acne after taking it. Because concentrated supplements haven't been as thoroughly studied as olive oil and olives as food, it's wise to get your doctor's approval before starting, especially if you're on any medications or have health conditions.
Olive tree pollen can also trigger seasonal respiratory allergies in sensitive people.
Meds to double-check
No known interactions
No interactions are documented in our data for olive leaf extract. That absence isn't a guarantee that none exist, so do run your exact medications through the search tool on this page and confirm with your doctor or pharmacist before you start.
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 extract for general wellness, this product seems generally well tolerated based on what we know. Because the evidence for specific health claims is still uncertain and concentrated supplements aren't as well studied as the whole foods, it makes sense to talk with your doctor or pharmacist first — they can weigh whether it fits your situation.
