Can You Take L-Arginine and Resveratrol Together?

Dose or timing may matter

The short answer

L-Arginine provides nitric oxide substrate while resveratrol activates eNOS. Both promote vasodilation and their combination may cause additive blood pressure reduction.

How to arrange timing

Monitor blood pressure when combining these vasodilatory supplements.

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.
