Can You Take Beetroot Extract and Citrulline Together?

Dose or timing may matter

The short answer

Beetroot (dietary nitrates) and citrulline (NO precursor) both increase nitric oxide levels through different pathways. Combining them may cause excessive vasodilation and hypotension.

How to arrange timing

Monitor blood pressure. Research suggests using lower doses of each when combining these two nitric oxide boosters.

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.
