That’s a typical “alarm headline” designed to sound dangerous, but it’s usually oversimplified.
Magnesium is an essential mineral, and in normal dietary or supplement doses it’s safe for most people. The real issue is specific drug interactions, not a blanket “never use it” rule.

When magnesium can interact with certain medications
Magnesium can reduce absorption or affect how some drugs work if taken at the same time:
- Antibiotics (like tetracyclines or fluoroquinolones)
→ Magnesium can bind to them and reduce effectiveness - Thyroid medication (levothyroxine)
→ Can reduce absorption if taken together - Bisphosphonates (for bone health)
→ Magnesium may interfere with absorption - Some blood pressure medications or diuretics
→ May affect electrolyte balance (doctor monitoring needed)
Important clarification
- These are usually timing issues, not absolute bans
- Often solved by spacing doses by 2–4 hours
- Many people safely take magnesium with medical guidance
When to be cautious
- Kidney disease (risk of magnesium buildup)
- High-dose supplements without medical supervision
Bottom line
Magnesium is not something you must “never use” with medications. The real rule is: check timing and medical conditions, not fear-based bans.
If you want, tell me the specific medication mentioned in the post, and I can explain the exact interaction clearly.
