Can You Take Beetroot Extract and L-Arginine Together?

Dose or timing may matter

The short answer

Beetroot provides nitrates converted to nitric oxide via the nitrate-nitrite-NO pathway, while L-Arginine produces NO via the L-arginine-NOS pathway. Dual pathway activation may cause excessive BP reduction.

How to arrange timing

Monitor blood pressure when stacking these nitric oxide sources. Consider using one pathway at a time.

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.
