From the Guidelines
Magnesium glycinate is the most suitable magnesium supplement for cardiovascular issues due to its high bioavailability and gentle effect on the digestive system. When considering magnesium supplements for cardiovascular health, it's essential to prioritize options that are well-tolerated and effective.
- Magnesium glycinate is a highly bioavailable form of magnesium, making it an excellent choice for supporting heart health.
- A typical dosage ranges from 200-400mg of elemental magnesium daily, often divided into two doses with meals, as suggested by general clinical guidelines, although specific studies like 1 do not provide explicit dosage recommendations for magnesium supplements in the context of cardiovascular disease prevention.
- Other forms of magnesium, such as magnesium taurate, may also be beneficial for cardiovascular health, as taurate itself has additional heart benefits, but the current evidence does not strongly support one form over another for general CVD prevention 1.
- It's crucial to start with a lower dose and gradually increase to avoid digestive discomfort, and to consult with a healthcare provider before starting any magnesium supplement, especially if you have kidney disease or are taking medications, as magnesium can interact with certain drugs including antibiotics and blood pressure medications.
- The role of magnesium in supporting heart health includes regulating heart rhythm, relaxing blood vessels, potentially lowering blood pressure, and helping maintain proper muscle function in the heart, as well as playing a role in energy production and potentially reducing inflammation, although the evidence for these benefits in the context of supplement use is not as strong as that for dietary magnesium 1.

From the Research
Magnesium Supplements for Cardiovascular Issues
- The suitable magnesium supplement dosage for cardiovascular issues may vary, but studies suggest that a daily intake of 500 mg to 1000 mg may reduce blood pressure 2.
- A combination of increased magnesium and potassium intake, along with reduced sodium intake, may be more effective in reducing blood pressure than single mineral intake 2.
- Oral magnesium can act as a natural calcium channel blocker, increase nitric oxide, improve endothelial dysfunction, and induce direct and indirect vasodilation 2.
- Magnesium plays a key role in modulating neuronal excitation, intracardiac conduction, and myocardial contraction, and may have a major influence on the pathogenesis of cardiovascular disease 3.
- Observational data have shown an association between low serum magnesium concentrations or magnesium intake and increased atherosclerosis, coronary artery disease, arrhythmias, and heart failure 3.
- A systematic review of 49 clinical trials found that oral magnesium therapy can safely lower blood pressure in uncontrolled hypertensive patients taking antihypertensive medications, with a dosage of at least 240 mg/day 4.
- High-dose oral magnesium therapy (at least 300 mg/day) has been shown to be effective in treating cardiac arrhythmias, with good to very good results in 82% of patients observed 5.
- Maintenance of adequate magnesium status is important in the prevention and management of cardiovascular diseases that predispose to congestive heart failure 6.
