Can You Take Caffeine and Pterostilbene-Caffeine Complex Together?

Dose or timing may matter

The short answer

Pterostilbene-Caffeine Complex already contains caffeine. Adding standalone caffeine results in an excessive total caffeine dose that may cause jitteriness, insomnia, tachycardia, and anxiety.

How to arrange timing

Account for the caffeine already in the Pterostilbene-Caffeine Complex when calculating total daily caffeine intake. Do not exceed 400mg total caffeine per day.

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.
