Can You Take Eria Jarensis Extract and Synephrine Together?

Use extra care with this pair

The short answer

Eria Jarensis extract (N-phenethyl dimethylamine) and synephrine are both sympathomimetic amines. Their additive adrenergic stimulation significantly increases the risk of hypertension, tachycardia, and cardiac arrhythmia.

How to arrange timing

Avoid combining multiple sympathomimetic stimulants. If both are in a pre-workout product, verify the doses are conservative.

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.
