HelloPharmacist Scorecard of Oliver by Progressive Professional from Progressive Laboratories
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
Oliver contains one active ingredient: olive leaf extract. The capsule also includes inactive ingredients—gelatin, silicon dioxide, and vegetable lubricant—that help deliver the extract.
Does it work?
Couldn't assess
The effectiveness data we hold shows insufficient reliable evidence to rate olive leaf extract for osteoporosis, indigestion (dyspepsia), exercise-induced respiratory infections, shingles, influenza, or osteoarthritis. In short, we don't have solid evidence that it works for any of these conditions yet.
How safe is it?
Well-documented data
Olive fruit and olive oil as foods are very safe, but concentrated supplements like this one are less studied. Olive leaf extract appears to be generally well tolerated overall.
The most common side effects reported in trials were headache and stomach discomfort. One person in a trial reported skin problems and acne; additionally, olive tree pollen can trigger seasonal respiratory allergies if you're sensitive to it.
Because the safety profile of concentrated olive supplements isn't fully established, talk with your doctor or pharmacist before starting, especially if you have any health concerns.
Meds to double-check
No known interactions
No interactions are documented in our data for olive leaf extract. That said, if you take any medications, it's still smart to run them through the checker on this page before you start—or mention this supplement to your pharmacist.
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.
Oliver is a straightforward single-ingredient supplement with no documented drug interactions. The evidence for whether it actually works for its marketed uses isn't solid yet.
Most people tolerate it well, but concentrated olive supplements are less studied than olive oil and olives as food. Check with your own doctor or pharmacist to see if it's right for you.
