Frequently Asked Questions

Is olive leaf extract the same as olive oil?

No. While both come from the olive tree, olive leaf extract contains approximately 40x more oleuropein than extra virgin olive oil. The leaves are where the highest concentrations of protective polyphenols are found. Olive oil provides modest amounts of oleocanthal and hydroxytyrosol, but olive leaf extract is specifically concentrated for these bioactive compounds at immune-relevant doses.

What is the die-off reaction from olive leaf extract?

Some users report headache, fatigue, and flu-like symptoms when first starting olive leaf extract, often attributed to a Herxheimer (die-off) reaction as antimicrobial compounds affect gut bacteria and other microorganisms. While this theory is not conclusively proven, the phenomenon is commonly reported. Starting with a lower dose and gradually increasing over a week can minimize these symptoms.

Can I take olive leaf extract with blood pressure medication?

Olive leaf extract has been shown to lower blood pressure in clinical studies, so combining it with antihypertensive medications could cause excessive blood pressure reduction. If you are on blood pressure medication, consult your physician before starting olive leaf extract, and monitor your blood pressure regularly. Dose adjustments to your medication may be needed.
