Can You Take Licorice Root and Magnesium Together?

Dose or timing may matter

The short answer

Licorice root raises blood pressure via cortisol elevation and sodium retention, while magnesium is a vasodilator that lowers BP. The opposing effects may cancel each other out.

How to arrange timing

Licorice may counteract magnesium's blood pressure benefit. Additionally, licorice may increase urinary magnesium excretion.

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.
