Can You Take L-Arginine and Taurine Together?

Dose or timing may matter

The short answer

L-Arginine increases nitric oxide for vasodilation while taurine has direct vasodilatory and sympatholytic effects. Both lower blood pressure and may produce additive hypotension.

How to arrange timing

Monitor blood pressure when using both at higher doses.

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.
