Olive leaf extract

These are the amounts published trials administered — not a recommendation, and not a dose to copy. Trial participants were screened, supervised and given a characterised preparation. What is in a retail bottle is frequently not what was studied, and the amount that suits one person is not general advice.

• Studied for Blood pressure

  500–1000 mg

  Limited

  Standardised leaf extract, once or twice daily · Typically providing 50–100 mg oleuropein · 6–12 weeks

  Trials are small, and oleuropein content differs several-fold between products, so two capsules of the same milligram weight are not equivalent.

None of the timings below were directly compared in a trial. They reflect how the research happened to dose, or what the pharmacology implies — which is not the same as a timing being better.

• 🍽️With food

  Not enough

  Commonly taken with meals for tolerability. No absorption or outcome comparison between fed and fasted dosing has been published.

  Timing was not directly compared. This reflects convention or how the compound behaves in the body, not a trial showing this window works better.
