Can You Take Caffeine and Hawthorn Berry Together?

Dose or timing may matter

The short answer

Caffeine elevates blood pressure through sympathomimetic effects while hawthorn lowers it through vasodilation and positive inotropic action. The opposing mechanisms may reduce hawthorn's cardioprotective benefits.

How to arrange timing

Consider separating intake if using hawthorn for cardiovascular support. Caffeine may counteract hawthorn's blood pressure benefits.

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.
