Can You Take Caffeine and Chamomile Together?

Dose or timing may matter

The short answer

Caffeine's stimulant effects may counteract chamomile's calming GABAergic activity, reducing the effectiveness of both.

How to arrange timing

Separate intake by at least 2-3 hours for best results.

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.
