What is the recommended dosage for Magnesium?

General: 310-420 mg/day; Blood Pressure Support: 300-500 mg/day; Cardiovascular Support: 300-400 mg/day elemental magnesium

What are the side effects of Magnesium?

Potential side effects include: Diarrhea (especially magnesium oxide and citrate), Nausea, Abdominal cramping, Excessive doses may cause hypotension or cardiac depression.

What is magnesium and how may it support cardiovascular health?

Magnesium is essential for heart muscle contraction, electrical conduction, and blood vessel relaxation. Meta-analyses of prospective studies show that higher magnesium intake is associated with lower risk of cardiovascular disease, stroke, and type 2 diabetes. Magnesium deficiency is linked to arrhythmias and hypertension.

What dosage of magnesium has been studied for cardiovascular health?

Clinical trials for blood pressure reduction have used 300–500 mg of elemental magnesium per day. A meta-analysis of 34 RCTs found that magnesium supplementation at a median dose of 368 mg/day significantly reduced blood pressure. Magnesium taurate and glycinate are preferred forms for cardiovascular use.

What are the potential side effects of magnesium supplements?

Diarrhea is the most common side effect, particularly with magnesium citrate and oxide. High doses may cause hypotension, especially when combined with blood pressure medications. Individuals with kidney disease are at risk for hypermagnesemia. IV magnesium at excessive doses can cause cardiac arrest. Oral supplementation is generally safe at recommended doses.

About

Magnesium is an essential cofactor for over 300 enzymatic reactions including those regulating vascular tone. It acts as a natural calcium channel blocker, relaxing vascular smooth muscle and reducing peripheral resistance. A 2016 meta-analysis of 34 RCTs found magnesium supplementation significantly reduced systolic blood pressure by 2.0 mmHg and diastolic by 1.78 mmHg. Approximately 50% of the US population consumes less than the EAR for magnesium.

How It Works

Essential cofactor for >300 enzymatic reactions regulating vascular tone; acts as a natural calcium channel blocker relaxing vascular smooth muscle; modulates cardiac electrical activity by stabilizing potassium and calcium channels (anti-arrhythmic); supports endothelial nitric oxide production; regulates Na+/K+-ATPase critical for cardiac membrane potential.
