Can You Take Caffeine and Olive Leaf Extract Together?

Dose or timing may matter

The short answer

Caffeine raises blood pressure while olive leaf extract (oleuropein) has demonstrated hypotensive effects. Concurrent use may reduce olive leaf's blood pressure-lowering benefits.

How to arrange timing

If taking olive leaf for blood pressure management, consider limiting caffeine or separating intake times.

Important context

Whether supplements suit you together also depends on dose, product formulation, health conditions, and medication use. Ask a doctor or pharmacist first if you take medication, are pregnant or breastfeeding, or have a chronic condition.
