Guest guest Posted February 16, 2003 Report Share Posted February 16, 2003 Calcium Hype & Magnesium " How can one simple element have such diverse and potent physiological actions? One important way that magnesium works its miracles is through itsinfluence on and regulation of calcium, a mineral that's gotten than itsshare of media play in recent years. You'd have to have been locked in a cave on the most remote corner of Bora-Bora not to have heard the hype - particularly aimed at women over forty --- about taking more calcium to prevent deficiency and keep bones strong. And so now we have the entire nation chomping calcium antacids by the handful, drinking calcium-fortified orange juice, downing calcium supplements of all kinds in an effort to raise their intake of calcium. But guess what the calcium hype fails to point out? It takes both calcium and magnesium (along with vitamin D) as well as an entire intricate symphony of bit players (molybdenum, boron, phosphorous, adequate protein, and bone-building hormones) to properly build and maintain bone. In fact,-- high levels of calcium in the blood can actually weaken bone and make it more brittle! And to make matters worse, taking excessive calcium without magnesium will promote magnesium deficiency, leading to the development of any of the host of diseases we mentioned earlier. While its true that our bones need plenty of calcium to make them strong,-- if it reaches excessive levels *within other cells*, its quite harmful - a situation that can easily arise in the face of an unbalanced intake of calcium and magnesium. Let's see how this works. Beyond its role in making bones hard, calcium serves as a critical stimulating component in the generation of electrical impulses in many tissues throughout the body --- notably, the heart, the muscles, and the brain and nerves. Calcium resides in the tissues in the fluid that bathes the outside of the cells --- and that's where the cells want calcium to stay until it's called for. When its needed for the generation of an electrical impulse, the cells open tiny channels in their membranes - called, appropriately enough,--- the calcium channels --- to admit a controlled number of calcium ions. The inrush of these calcium ions alters the electrical charge within the cells and creates the spark for transmission of an electrical impulse. As soon as it has done its job, however, the cell hustles the calcium back out. In fact, calcium inside the cell is so toxic that the cells expend an enormous amount of energy keeping it in its proper place - on the outside. When too much gets in and remains inside the cell, bad things happen. Many disease processes occur because the tight regulation of the calcium channel fails,--- permitting calcium ions to flow into the cells unabated. Rising calcium levels within a cell activate its energy-production systems,setting in motion a variety of effects depending on the tissue in question. For example, calcium flowing unrestricted into the smooth muscle cells inthe coronary arteries of the heart can bring on arterial spasm and the chest pain called angina. Calcium overstimulation of the cells in the muscular layer of the temporal arteries (or others supplying blood to the brain) can cause migraine headaches. Excess calcium entering the cells of the smooth muscles surrounding the small airways in the lung causes constriction - called bronchospasm - and the resultant wheezing of asthma and other restrictive lung disorders. If too much calcium flows into the delicate cells of the brain, the repeated discharge of energy that follows may deplete their energy stores,--- killing the cells! Pharmaceutical companies have developed an entire family of drugs to prevent this excess flow of calcium into the interior of the cells. These drugs,-- called calcium channel blockers, are among the most versatile drugs on the market currently approved for a wide range of medical indications. All these disparate diseases respond to a single action: preventing excess alcium from entering the cell by blocking the calcium channel. Ah, the miracles of modern medical technology! But here the story gets even moreinteresting, and its one reason we titled this chapter " The Magnesium miracle " Magnesium is nature's calcium channel blocker, acting as a natural retardantto the flow of calcium ions into the cells. Adequate magnesium levels onthe inside of the cell prevent calcium's entry from without, and all is wellwithin the cell. If the interior of the cell becomes magnesium deficient,however, watch out! Calcium can then enter at will. Medical researchers have repeatedly demonstrated a low level of magnesium inside the cells invirtually every disorder treated by calcium channel blocking drugs. So why don't doctors treat these patients with magnesium instead of theterribly expensive prescription medications? For one thing, because drug companies can't patent natural substances, there's no army of pharmaceuticalrepresentatives knocking on the doctor's doors, crowing about the advantages of simple, cheap magnesium in treating these disorders. But the information does slowly trickle down, and the good news is, many physicians are beginning to use more magnesium in the treatment of disease. In the emergency room, physicians now routinely give magnesium directly intothe vein to relieve chest pain, stabilize the heart rhythm, and reduce orprevent the death of heart muscle cells during a heart attack. And more andmore in the ER, astute physicians, recognizing the power of magnesium torelax the spastic respiratory muscles and open the airways, have begun to give it by the IV route to break asthmatic attacks. (Several research studies have demonstrated that magnesium deficiency occurs nearly uniformlyamong asthma sufferers and that replacing it will reduce the number ofattacks.) Obstetricians have been on the magnesium bandwagon since long before we didour medical training, routinely giving intravenous injections of magnesiumsulfate to treat toxemia of pregnancy, rapidly reducing the malignant high blood pressure sometimes associated with labor and delivery. And since the discovery that virtually every patient admitted to the medicalintensive care unit is deficient in magnesium, its intravenous (IV)supplementation in these critically ill people has become commonplace. Unfortunately, most physicians don't yet use magnesium to prevent these disorders, mainly relying on it to treat diseases after they're present. As is too often the case with modern medicine, we close the barn door after the horse has gotten away. But that approach, we hope, is changing.
