Can I Take magnesium and b vitamins Together?

SUMMARY:

Magnesium supplements and B‑vitamin supplements are generally considered safe to take together with no major direct interactions reported. If you have kidney disease, take very high doses, or are taking other prescription medicines, check with a healthcare provider about timing and safety.

ADDITIONAL NOTES:

No direct interactions documented between magnesium and B‑vitamin products; they are commonly co‑administered or included together in multivitamin formulations. Magnesium can cause gastrointestinal upset (eg, diarrhea) at higher doses and may accumulate in people with significant kidney impairment. Mineral supplements (including magnesium) can interfere with absorption of some prescription drugs (for example certain antibiotics or thyroid medications), so separating dosing or consulting a clinician/pharmacist is advised if you take other medicines.
