Magnesium – Are You Getting Enough? Low Magnesium linked to Hypertension
Dr. David Brownstein, M.D., writes:
Approximately 75 million people in the United States over age 20 have high blood pressure.
After age 55, it’s estimated that Americans face a 90% chance of developing it.
The “good” news is that a doctor can diagnose high blood pressure (also called hypertension) in just a few minutes. All too typically, the doctor will then prescribe an antihypertensive medication and advise the patient to take it for the rest of his or her life. In fact, this drug treatment is often not needed.
Magnesium helps to relax the smooth muscles of blood vessels, resulting in less resistance to blood flow, which helps to lower blood pressure. The mineral also reduces nerve and muscle excitability. In addition, magnesium helps optimize circulating levels of the hormones norepinephrine and serotonin, and levels of nitric oxide.
Nitric oxide is a powerful vasodilator — a substance that opens blood vessels for better flow. It is interesting to note that nearly all synthetic anti-hypertensive medications work to reduce blood pressure by a similar mechanism. However, all of those drugs are associated with severe adverse effects.
Diarrhea, the only adverse side effect of magnesium, is easily solved by lowering the dose. Studies have clearly shown the benefits of magnesium. One found that 625 mg per day caused a significant decline in blood pressure.
Diuretics, the most commonly prescribed anti-hypertensive drugs, accelerate magnesium loss and lead to deficiency. In addition, lack of magnesium hinders the use of potassium in cells. But oddly enough, diuretic drugs also lower potassium levels.
