Can you take Iron and Magnesium together?

How to think about iron and magnesium timing, supplement spacing, and interaction tracking.

Short answer

Separate them when you want a cleaner protocol.

The useful question is not only whether two supplements can appear in the same stack. It is whether the schedule makes the pair easier to take, safer to review, and easier to measure.

Why the timing matters

Iron is usually the more sensitive supplement in the pair, while magnesium can be moved to a night window without making the routine harder.

For App Store screenshots and real users, this is also a trust issue: a supplement app should not recommend a schedule and then undermine that same schedule with vague warnings.

How to track the pair

If your clinician has you taking iron, log it as a priority dose and schedule magnesium around it rather than the other way around.

In Stackhero, Iron and Magnesium should each keep their own dose, form, timing window, and adherence history so the interaction result stays explainable.
