Magnesium Can Be Incredibly Beneficial — But Only If It Doesn’t Clash With Your Meds. Check This List Before Supplementing – Page 4

Quick Reference List of Timing Tips:

Take magnesium at least 2 hours before or 4–6 hours after certain antibiotics (check with your pharmacist for the exact window).
Separate magnesium from oral bisphosphonates by at least 2 hours.
Avoid taking magnesium and high-dose zinc at the exact same time if possible.
Always read the specific guidance on your prescription labels.

But that’s not the full picture. Some interactions are about reduced absorption, while others involve how your body maintains mineral balance over weeks or months.
