Can You Take Potassium and Magnesium Together?
May affect absorption
The short answer
Potassium and magnesium can compete for renal reabsorption. However, magnesium deficiency can worsen potassium retention, so adequate magnesium supports potassium balance.
How to arrange timing
Space high doses at least 1-2 hours apart for optimal absorption.

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.
