Magnesium - "The Missing Mineral"
In 2006, the World Health Organization reported that a majority of the world's population is magnesium deficient. Likewise, in 1995, the Gallop Organization conducted a survey and found that 72% of adult Americans consume less than the RDA for magnesium.
Estimated U.S. Intake of Magnesium Recommended Daily Allowance
Since magnesium has so many roles in the body, its deficiency is therefore involved in many health Problems. Increasing the body's magnesium levels is thus a "no-brainer" for those experiencing magnesium deficiency-related health problems.
Many Health Benefits of Magnesium
The many "hats" of magnesium in the body
Blood tests for magnesium deficiency are misleading, since blood magnesium level may be normal in spite of a significant magnesium deficiency. Most magnesium is inside cells and < 1% of the body's magnesium is in the blood, which the body works hard to keep at a constant level.
What happens when magnesium intake is insufficent? If magnesium within the cell becomes depleted from its normal level, then calcium levels increase inside the cell - i.e. the intracellular Mg : Ca ratio decreases having an impact on cell functions, which incidentally includes impacting all aspects of the stress response ("Fight-or-Flight"reaction). In a life-threatening crisis, such reactions can be life-saving as they allow a person to perform with unusual strength and speed, and then levels return to normal when the stress is over. However, when a low intracellular Mg : Ca ratio is due to nutrient deficiency, these become chronic conditions:
The following symptoms indicate increased requirement for magnesium. Not all symptoms need to be present to assume deficiency, But many of them often occur together

| At a Glance - Factors affecting our Magnesium Levels | ||
|---|---|---|
| PRO- CESSES |
Magnesium deficiency in soil - today's common use of potassium and phosphorus based fertilizers causes these minerals to be taken up by plants in preference to magnesium and calcium; magnesium and calcium used up neutralizing nitric acid in acid rain; herbicides/pesticides kill bacteria/worms that enable plants to absorb minerals. | Water-treatment methods - deplete
mineral content, including magnesium; water from deep wells supplies more than
surface water, typically the source of city water. Most filtered, bottled
water provides little or no magnesium. Fluoride in water / toothpaste - binds magnesium |
| Magnesium lost in food processing and refinement - 80+% lost in flour milling. Not in the oils of magnesium-rich nuts/seeds | Soaking / boiling / broiling /steaming foods** - leaches magnesium into the water or drippings. Magnesium is in the broth or vegetable water; | |
| COND- ITIONS |
Malabsorption Disorders - Prevents
effective use of magnesium: any intestinal inflammatory disease. E.g. Crohn's, celiac disease; leaky gut; gluten / casein insensitivities; fungi/parasites; fat malabsorption (greasy /offensive stools; magnesium binds to unabsorbed fat; usually no gall bladder, gallstones) |
Removal of any part of small intestine -
reduces magnesium absorption Low stomach acid production - needed for digestion, decreases with age |
| Mental and Physical stress -
any "fight or flight" reaction increases
magnesium need;
Eg. worry/anxiety, perfectionism, anger, guilt, lonliness, fear, overwork,
lack of sleep, troubled relationships, career/financial pressure; Type A's (aggressive; living on adrenaline, time pressure, and stress) drain the body of magnesium - Prolonged psychological stress raises ADRENALINE, the stress hormone, which depletes magnesium. Surgery / Chronic Pain / Large area burns / Chronic Disease / infections / extreme temperatures Stress causes magnesium deficiency / magnesium deficiency magnifies stress reaction - Studies associate the stress hormones ADRENALINE and CORTISOL with decreased magnesium. Stress decreases stomach acid (HCl) needed for effective magnesium digestion/absorption; |
||
| Sweating / Diarrhea / Excessive vomiting - causes loss of magnesium. Eg. regular use of saunas / steam rooms. | Larger people - have higher amounts of magnesium in their body, which lowers magnesium absorption, regardless of source. | |
| Diabetes - magnesium excretes in urine with sugar | High bloodINSULIN levels | |
| Aging - > 55 may impair magnesium uptake. | Excessive physical exercise / over-training | |
| DIET | Sugar, caffeine, coffee,
tea, sodas, alcohol ALL increase magnesium excretion
in the urine Alcohol - more than 7 drinks / week (significant loss) Coffee (significant loss) Tea - tannins bind magnesium Soda - (diet or not, especially colas) - most dark colored sodas contain phosphates, which bind with magnesium in the GI tract, rendering it unavailable to the body. Refined sugar - not only lacks magnesium, since sugar-refining removes magnesium-containing molasses from sugar cane, but it also causes the body to excrete magnesium through the kidneys. Average consumption of carbonated beverages has increased 10-fold since 1940, and is certainly responsible for the body's reduced availability of both magnesium and calcium.

|
| Phytic acid - in cereals, most grains, nuts, seeds; binds magnesium; | ||
| High carbohydrate intake - white sugar/flour, HFCS; | ||
| Trans fats / excess saturated fat - alter cell membrane integrity disrupting magnesium transport in/out of cells | ||
| Highly refined table salt intake | ||
| Oxalic acid ( e.g. in rhubarb, spinach, chard, cocoa, almonds) - intake may form insoluble magnesium salts with magnesium | ||
| High calcium levels - blocks magnesium uptake. E.g. from overuse of calcium carbonate antacids. | ||
| Low potassium levels - can increase urinary loss of magnesium | ||
| Vitamin D, calcium and phosphorus - reduce magnesium uptake. A high phosphorus blood level tends to cause magnesium and calcium levels to be low | ||
| High or low protein diets -can decrease magnesium absorption | ||
| Dieting - reduces magnesium intake; causes stress; | ||
| DRUGS | Amphetamines, Antacids, Antibiotics, Cocaine, Corticosteroids, insulin, diuretics (even potassium sparing types) / birth control pills, Estrogen Replacement Therapy, heart and asthma medications, Phentermine or Fenfluramine (appetite suppressants), Warfarin (anticoagulant), Cyclosporine (immunosuppressant). EXTRA magnesium is protective. These drugs deplete body's magnesium | |
** Soups retain some magnesium in water; magnesium content retained after cooking varies greatly with the food - Where magnesium in a food is found mostly in water-soluble form, blanching/steaming/boiling results in a substantial loss of magnesium. E.g. ~ 1/3 magnesium is lost blanching spinach and cooking navy beans loses 65%. However, as long as whole almonds are used, the magnesium is retained even after roasting or making into almond butter.
