Benefits of Magnesium: Heart Conditions
The American Heart Association reports that over 60 million Americans have one or more types of cardiovascular disease, the leading cause of death in the United States.
Magnesium deficiency has been shown to be associated with a number of cardiovascular problems*, including:
High blood pressure
 |
Epidemiological studies have shown an inverse relationship between dietary magnesium intake and blood pressure1. |
 |
Magnesium is also considered to be a natural calcium-channel
blocker and vasodilator2 which may be
helpful for patients with mild hypertension. |
 |
Many diuretics, often used for patients with high blood pressure,
cause potassium and magnesium depletion. Often times magnesium supplements are prescribed for patients taking thiazide and loop diuretics3. |
Heart attacks4
 |
A number of heart attack patients have been found to have low magnesium levels. |
 |
Magnesium, which has calcium channel blocking properties may promote
myocardial salvage. |
Abnormal heart rhythms
 |
Studies have linked magnesium depletion with tachycardia and other abnormal heart rhythms5. |
 |
Low magnesium levels may play a significant role in the high prevalence of cardiac arrhythmias and heart failure6. |
Coronary artery disease (CAD)
 |
Epidemiological evidence that links magnesium deficiency to coronary artery disease has been investigated for over 30 years7. |
 |
Magnesium may be justified as an adjuvant therapy for CAD patients8. |
Diabetes
 |
Magnesium depletion may cause a worsening of the diabetic condition because of the influence of magnesium on insulin function and glucose metabolism9. |
 |
Chronic magnesium supplementation produced a significant
reduction of plasma cholesterol and LDL cholesterol, and an increase of HDL cholesterol. These results
suggest that oral supplementation of magnesium may be helpful for hyperlipidemia patients with
non-insulin-dependent diabetes mellitus10. |
