Can You Take Vanadium and Vitamin C Together?

Dose or timing may matter

The short answer

Vanadium has nephrotoxic potential, and high-dose vitamin C generates oxalate requiring renal excretion. Together they place multiple stressors on kidney function.

How to arrange timing

Keep vanadium under 1 mg/day and vitamin C under 1,000 mg/day. Monitor kidney function if using both.

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.
