Practical advice

No interaction between Magnesium and Naproxen has been documented. As a best practice, keep a list of everything you take — including Magnesium — and share it with your healthcare provider at every visit. This helps them spot potential issues early.

Timing

Take both with food — this improves mineral absorption and protects the stomach from NSAID irritation. Iron can darken stools, which can be confused with NSAID-related GI bleeding. Note the baseline color of your stools when starting iron supplementation so you can distinguish between the two.

Risk factors

Higher risk for: elderly, those with history of GI bleeding or ulcers, renal impairment, concurrent anticoagulant or corticosteroid use, cardiovascular disease, or chronic high-dose NSAID use.

Symptoms to watch for

Monitor for GI, kidney, and cardiovascular effects when combining Magnesium with Naproxen. Watch for: stomach pain, heartburn, nausea, black or bloody stools, decreased urination, ankle swelling, unusual weight gain (fluid retention), or elevated blood pressure. When to seek emergency help: Vomiting blood or material resembling coffee grounds, severe abdominal pain, chest pain, sudden shortness of breath, signs of allergic reaction (hives, facial swelling, difficulty breathing), or very dark urine with reduced output.

What to tell your doctor

No urgent need to discuss, but always keep your doctor informed of your full supplement and medication list. An up-to-date list helps them make the best treatment decisions.

Safer alternatives

Safe combination. Mineral absorption tip: take calcium and iron at separate times (they compete for absorption). Magnesium is best taken in the evening. Zinc pairs well with meals to prevent nausea. Vitamin C enhances iron absorption.
