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.
Common questions
When should you take iron if magnesium is at night?
Morning iron, evening magnesium is the clean split, and it gives you far more than the 2 hour minimum. The gap protects the iron dose, which is the one correcting a deficiency.
