Can you take magnesium and iron together?

Yes, but space them out

Take both, just not at once: magnesium can reduce iron absorption, so separate them by about 2 hours.

What happens when you combine them

Iron is the fussiest mineral in the catalog, and magnesium is one of the things that blunts it: taken together, iron absorbs less. That matters because iron is usually supplemented to correct a deficiency, where every milligram absorbed counts.

The interaction is one-directional in practice. Your magnesium dose loses little; the iron is what you're protecting.

How to time it

Iron takes the morning, away from calcium, fiber, and magnesium. Magnesium takes the evening. If iron bothers your stomach, a small meal is fine, just keep other minerals out of it. Vitamin C is the one companion that helps: it enhances iron absorption.
