SingleCareShould You Take Magnesium for Hypertension?

Magnesium supplementation has been linked to small blood pressure reductions in some studies, particularly among magnesium-deficient individuals. Overall evidence remains mixed.

Editorial Note: Evidence on magnesium supplementation shows mixed and modest effects on blood pressure. Findings do not support magnesium as a treatment for hypertension and should be considered adjunctive only.

Clinical Considerations

• Average BP changes are small and inconsistent.
• Greater impact is seen in deficiency states.
• No trials link supplementation to outcomes.
• Interaction-related hypotension can occur.

Practice Applications

• Frame magnesium as adjunctive, not therapeutic.
• Reinforce guideline-based hypertension care.
• Monitor for drug interactions and symptoms.
• Encourage supervised use only.
