Can You Take Iron and Rubidium Together?

May affect absorption

The short answer

Rubidium, as a monovalent cation, may interfere with iron absorption by competing for non-specific cation transport pathways in the intestinal epithelium.

How to arrange timing

Separate rubidium and iron supplements by at least 1 hour.

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.
