Magnesium is one of the body’s most important minerals. It is required as a co-factor in hundreds of enzymatic processes within cells.1 It helps maintain normal muscle and nerve function, keeps heart rhythm steady, promotes a healthy cardiovascular function, supports a healthy immune system, and keeps bones strong. Magnesium also helps maintain blood sugar and blood pressure levels already within normal range, and it is known to be involved in energy metabolism and protein synthesis.2,3 Magnesium is a major factor in relaxing the smooth muscles within the blood vessels, thereby reducing peripheral vascular resistance and promoting a healthy cardiovascular system.3-5 Magnesium also affects circulating levels of norepinephrine and the synthesis of serotonin and nitric oxide.1,6-8 Magnesium positively influences the bone mineral matrix and its ability to metabolize minerals needed for repair and rebuilding.9,10 The scientific literature documents the need for a wide range of minerals, including calcium and magnesium, that are vital to maintaining strong, healthy bones. Magnesium's Importance in a Healthy Cardiovascular System Magnesium plays an important role in the functioning of the cardiovascular system. A decrease in magnesium has been linked with tachydysrhythmias (fast, irregular heartbeats) and increased mortality in CHF patients.12 The research shows that use of magnesium supplements in these situations may be beneficial for treating and preventing life-threatening conditions. Magnesium supplements can be administered safely either orally or by injection depending on the situation.13,14 In one study, patients with severe CHF took a supplement of 300 mg of oral magnesium citrate daily for 30 days. In some of these patients, oral magnesium supplementation was effective in achieving substantial increments in intracellular magnesium.13 Magnesium in Hypertension Prevention and Control Which nutrients are the most important for maintaining a healthy blood pressure? Two that stand out are the metallic elements potassium and magnesium. Magnesium is one of the body’s most important minerals. It is required as a cofactor in hundreds of enzymatic processes within cells.15 Magnesium is a major factor in
Indeed, because of magnesium’s primary role in blood pressure regulation, for decades scientists have called magnesium “nature’s calcium channel blocker” because magnesium directly offsets the constriction of blood vessels caused by calcium.15,18 Because drug companies cannot make money from a natural substance like magnesium, they have developed a whole group of drugs called calcium antagonists or calcium channel blockers to do what magnesium does. In 2000, doctors wrote more than 95 million prescriptions for calcium antagonists, including top sellers amlo-dipine (Norvasc®), nifedipine (Procardia®), diltiazem (Cardizem®, Tiazac®), and others at a total cost of more than $4.5 billion.20 These drugs are not only costly, but they can also cause side effects such as dizziness, palpitations, fatigue, tiredness, and swollen legs. Yet many doctors do not hesitate to prescribe these drugs because they were never taught about magnesium. While legions of pharmaceutical sales representatives bring stacks of studies and free samples of these drugs, no one pushes magnesium.21 Magnesium and Treatment for Migraines Migraine is not a single disorder, but a collection of disorders. According to our hypothesis, a migraine involves faulty hormonal feedback in the hypothalamic-pituitary-adrenal-gonadal axis. Contributing to this hormonal abnormality is an imbalance between two of the three arms of the autonomic nervous system (the sympathetic and parasympathetic nervous systems), which causes a decline in the brain’s pain threshold. Because of disequilibrium between intra- and extracellular calcium and magnesium, the polarity of the cell membrane is changed, which affects the electrical stability of the cell membrane and sensitivity to neurohormonal impulses (steroid hormones, melatonin, and serotonin). Lastly, the intestinal flora is altered, which results in abnormal absorption. During the last 15 years, many researchers have proposed that migraine is generated by a hyperexcitable brain. A migraine attack can be triggered at any time, depending on the threshold of brain excitability, and in fact, the frequency of migraines is proportional to the excitability level. According to classic theory, a migraine attack is initiated by a cerebrovascular spasm followed by extracranial vasodilatation. This change may be caused by an imbalance in brain biochemistry. Decreased cellular oxygen can cause an increase in the flow of calcium from the extracellular fluid to the intracellular space, resulting in a calcium overload and cellular dysfunction.22 Disturbances in mitochondrial oxidation reactions, magnesium deficiency, or abnormalities of cellular calcium channels may be responsible for the neuronal hyperexcitability between attacks.23 Clinical studies by the Life Extension foundation indicate that the restoration of calcium-magnesium balance is one of the critical issues in migraine therapy. Magnesium, Allergies and Asthma Asthma is largely due to allergies. Asthma can be brought on by many causes: food and beverages, and the sulfites in them, or environmental allergens: fresh paint, perfumes, spray deodorants, cigarette smoke, gasoline or car exhaust fumes; hay, wood, coal or chalk dust; various chemicals such as cleaning solvents, household cleaners and insecticides; pollen and mold. Home humidifiers and air conditioners have been identified as harbors of bronchial-constricting molds. When eliminating offending allergens, leave no filter unchanged. As magnesium levels decline, the incidence of allergies and asthma increases. A dose of 1000 mg a day of magnesium is recommended (Hijazi et al. 2000).
