Can You Take Caffeine and Eria Jarensis Extract Together?
Use extra care with this pair
The short answer
Eria Jarensis extract contains N-phenethyl dimethylamine, a potent sympathomimetic stimulant. Combined with caffeine, the additive CNS and cardiovascular stimulation may cause excessive heart rate elevation, hypertension, and anxiety.
How to arrange timing
Reduce doses of both when combining. Monitor heart rate and blood pressure closely. Avoid if you have cardiovascular conditions or anxiety disorders.

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.
