Magnesium is essential to life . Even a fairly subtle deficiency can lead to pain, suffering and an early death. However, as important as it is, it is likely that neither you nor your doctor have heard much about this mineral. Why? It is because magnesium is inexpensive and not patentable. Therefore it lacks the economic incentive that drives most research, medical education and media coverage.

Magnesium is involved in 300+ of the body's chemical reactions , so it is not surprising that there are at least 40 common scientifically-documented symptoms of insufficiency. Here are just a few:

•  Sudden death from cardiac spasm and arrhythmias, even among those who do not appear to have known risk factors for heart disease (e.g. among athletes)
•  Increased death rate among those hospitalized with heart attacks
•  Colon cancer
•  High blood pressure
•  Elevated cholesterol
•  Aggravation of migraine headaches
•  Muscle spasms and leg cramps (also monthly cramps)
•  Asthma
•  Reduced detoxification of chemicals, e.g. those who react strongly to "sick building syndrome"
•  Kidney stones
•  Osteoporosis
•  Nervousness, hyperactivity, being easily startled, depression, anxiety
•  Persistent fatigue
•  Constipation
•  Toxemia of pregnancy, etc., etc.

Magnesium insufficiency is widespread . A government study showed that the average American only gets 40% of the recommended amount and just 1 person in 4 gets a paltry 400 milligrams/day. It is shocking that hospitals only check 10% of cardiac patients for magnesium status. When they are checked (with an insensitive test at that), 70% are deficient. Ironically, some drugs given to suppress cardiac symptoms (e.g. diuretics) may actually aggravate the magnesium deficiency that might have been the cause of the symptoms.

Magnesium is relatively abundant in natural foods such as whole grains . However, when whole grain wheat is turned into white flour or brown rice is made into white, approximately 80% of the magnesium is removed along with a couple dozen more nutrients. A few are added back to what is laughably called "enriched" flour, but magnesium is not one them. Breads, cereals, burger buns, pizza crust and snack foods from white flour are a staple of the American diet. [Curiously, the FDA has maintained in the past that the natural foods industry could not suggest that whole-wheat bread is superior to white. ]

Fresh green vegetables are also an excellent source of magnesium as are unrefined soybeans, seafood, figs, apples, almonds and chocolate (is that why we crave it?). Cooking may lower levels. Magnesium is also available as a supplement . The “oxide” forms are cheap but poorly absorbed and more likely to cause GI distress. Most people should not take calcium without magnesium and the other nutrients needed to assure its incorporation into bone. A comprehensive bone formula is the best way to assure balance and complete coverage.

Toxicity is rare . Excess causes a loose stool temporarily—a clear signal to reduce the dose. Persons with pre-existing kidney disease should check with their nutrition-trained physician before adding supplemental magnesium.
