HelloPharmacist Scorecard of Olive Leaf 500 mg by Natural Factors HerbalFactors
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 is the dried or concentrated form of leaves from the olive plant, traditionally used to support various aspects of health.
The capsule also holds rice powder, gelatin, and magnesium stearate as inactive ingredients that help form and preserve the supplement.
Does it work?
Not established
The evidence for olive leaf extract is not established for the conditions it's traditionally used for — osteoporosis, indigestion, exercise-related respiratory infections, shingles, influenza, and osteoarthritis all carry a rating of insufficient reliable evidence. That means the studies we have either don't exist, aren't robust enough, or don't give us a clear answer yet.
If you're considering this for a specific health concern, talk it over with your doctor or pharmacist to see whether there's a better-studied option available.
How safe is it?
Well-documented data
Olive leaf extract appears to be well tolerated overall. The most commonly reported side effects from trials are headache and stomach discomfort.
One person in a trial reported acne or skin changes, and olive tree pollen can trigger seasonal respiratory allergies if you're sensitive. The caution here is that olives and olive oil as foods are very safe, but concentrated olive leaf supplements are less well studied than the food forms — so the long-term safety profile isn't as clear.
Data on use during pregnancy or breastfeeding is not on file; talk with your doctor or pharmacist before using it if you're pregnant, nursing, or planning to become pregnant.
Meds to double-check
No known interactions
No interactions are documented in our data for this ingredient. Still, it's worth running any medications you take through the search tool on this page, or confirming with your own pharmacist or doctor before you start — especially if you're on blood thinners, blood pressure medications, or anything else you're unsure about.
The bottom line
Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. No medication interactions are currently documented, and safety information is well characterized.
Olive Leaf 500 mg is generally well tolerated and shows no documented drug interactions. However, the evidence for its effectiveness isn't established yet, and the safety of concentrated supplements (as opposed to whole olives or olive oil) is less studied than we'd like.
If you're thinking about trying it for a particular reason, check in with your doctor or pharmacist to make sure it fits your health plan.
