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.
