Uses For Magnesium In Industry
1. Magnesium is one of the most important, if not the most important elements needed in the human body. It has so many uses that we cannot describe them all.
2. Everyone is deficient in magnesium. The reasons are:
- Depleted soils. The soils of the earth are all low in magnesium. As a result, all the food is low in magnesium.
- Food refining. drastically reduces the magnesium that is left in many common foods. For example:
- Refining whole wheat flour into white flour removes most of the magnesium in the flour.
- Processing whole grain rice into white rice removes a lot of magnesium.
- Processing sugar cane or sugar beets into refined sugar also removes a lot of magnesium.
- Inadequate diets. For instance, most people do not eat nearly enough well-cooked vegetables, sardines, almond butter, kelp and other foods that are required to obtain enough magnesium.
- Improper eating habits. These include eating too fast, eating on the run or in your car, eating in noisy environments, drinking liquids with meals, and eating bad food combinations.
- Impaired digestion. Most people have poor digestion due to stress, nutritional deficiencies, intestinal infections, improper intestinal flora, general weakness of the body, parasitic infestations, and toxic metal/toxic chemical poisoning.
- Magnesium antagonists. These include alcohol use and vigorous exercise.
The result is a horrible level of magnesium deficiency in all population groups on earth. We very rarely find anyone who does not need a magnesium supplement.
3. Magnesium supplements are not sufficient. Another challenge with magnesium is that supplements, while helpful, do not replace all of the vital magnesium compounds the body need.
The only answer is to supply more of the foods that contain magnesium, and these are few. They are discussed in the section below.
4. Obtaining enough of the best quality magnesium for health and development is a constant battle and search.
EXCELLENT SOURCES OF MAGNESIUM
Unfortunately, these are few. Among the best are:
- Well-cooked vegetables are among the best sources. Among the vegetables, the best are all the onions (especially pearl onions), carrots, celery (just a little needed), daikon and green beans.
- Sardines contain an excellent magnesium compound that is required for development.
- Kelp. This is an excellent source of magnesium.
- Some spring water. Distilled and reverse osmosis water are terrible to drink in this regard because they provide no minerals at all.
- Bamboo jade sea salt. Some other natural sea salts are okay, as well, but this one is excellent.
- Seeds such as sesame, pumpkin, and a few others contain good magnesium compounds. We don’t recommend seeds because they are difficult to digest. However, we strongly recommend organic toasted sesame tahini, two tablespoons daily for adults and less for children, or 4 tablespoons daily of hummus, which contains tahini for adults and less for children.
- Nuts such as almonds contain some good forms of magnesium. Once again, one must be careful because nuts are similar to fruits and quite yin. We only recommend toasted almond butter, two tablespoons daily for adults. This is a very important food for development and every adult needs to eat it daily. Children also need some, as well.
- Meats contain some magnesium. It is one reason we avoid vegetarian diets, which are lower in magnesium. Raw or very rare organic ground beef has an excellent form of magnesium. Unfortunately, it is not heat-stable and most people overcook their hamburger for fear of infection. Organic ground beef is a fairly clean product and should be eaten when cooked rare, not well done or even medium.
Chicken has some magnesium, as well.
- Egg yolk has a decent form of magnesium. However, it is not heat-stable. The yolk must be uncooked or lightly cooked only. Hard-boiled eggs, scrambled eggs, omelets, quiche and other products made with cooked egg yolk fail to offer this important nutrient.
FOODS LOW IN MAGNESIUM
Most of the foods people eat today are very low in magnesium. These include white flour, white sugar and white rice. Others are fruits, soda pop, and cows milk dairy products. These contain very little magnesium!
Maintaining osmotic or water balance. Magnesium is very abundant in the body, and considered one of the macrominerals and an electrolyte. This means it helps maintain the osmotic balance of the blood and tissues. It is present in every cell of the body.
Deficiency states can cause edema or swelling of the body, dryness of the body, constipation, diarrhea and other conditions related to the water balance of the body.
Maintaining cell membrane potential or charge. Along with potassium, magnesium is a primary intracellular mineral (found inside the cells). This is the opposite of calcium and sodium, which are found in higher concentrations outside of the cells of the body. The body pumps magnesium into the cells and pumps calcium and sodium out of the cells. This sets up an electrical charge of each cell that keeps the body functioning correctly.
Magnesium deficiency is associated with a reduced electrical potential of the cell membrane and a lower sodium/potassium ratio in the hair tissue, and perhaps the blood. This is a very serious electrical imbalance.
A major enzyme component. Magnesium is required for thousands of critical enzymes everywhere in the body. Many of the following functions involve magnesium-dependent enzymes.
Magnesium is one of very few minerals that cannot be replaced by a less preferred mineral in many enzymes. What does occur, however, is that an inferior form or compound of magnesium can replace a better form of magnesium when a person’s body is nutritionally deficient. To understand the idea of preferred minerals, read Preferred Minerals.
Deficiency of magnesium therefore can cause problems in most body systems!
A powerful anti-inflammatory nutrient. Magnesium helps reduce aberrant inflammation in the body. It does this by solubilizing or dissolving calcium deposits that are abnormal and are very irritating to the body tissues. It also helps rid the body of other irritating toxins such as heavy metals and toxic chemicals that cause inflammation.
Deficiency causes rampant inflammation which is the main cause of pain in the body. Inflammation, in turn, releases cytokines and other chemicals that further damage all tissues of the body. Chronic inflammation is also associated with cancer formation, heart disease, diabetes, Alzheimer’s disease and dozens of other serious conditions.
A high energy mineral. The Krebs or carboxylic acid cycle requires plenty of magnesium. Otherwise, ATP or energy production declines severely in the body. This is why taking a magnesium supplement often acts as an energy booster.
Deficiency leads to fatigue, general malaise, depression, apathy, inability to repair the tissues, despair and suicidal thoughts.
The nervous system. Magnesium plays an important role in the nervous system. Here it regulates certain brain activities. This is why taking a magnesium supplement can help a person relax and think better.
Deficiency results in mental dullness or sluggishness, memory impairment, inability to process information properly, learning disabilities, delayed development, irritability, and horrible anxiety in some people.
The heart. Magnesium is one of the most important minerals for the heart. It is a regulator of the heart, it gets rid of oxidant mineral forms that damage the heart, and it does even more than this.
Deficiency can contribute to heart rhythm irregularities, palpitations, tachycardia and heart attacks. Even medical doctors know about this function of magnesium. They routinely give anyone who has a heart attack an injection of magnesium when the person enters the emergency room. It works to stabilize the heart and relax the person.
Often, a magnesium injection at the hospital or by a paramedic saves the person’s life. In fact, if the person were not magnesium deficient, often he or she would not have had the heart attack.
Anti-oxidant properties. Magnesium functions as an anti-oxidant. This is an important use of magnesium by the body. This has a calming and healing effect.
Deficiency is associated with oxidant damage to the tissues and a shortened lifespan.
Anti-spasmodic. Magnesium relaxes the muscles, along with calcium. Calcium alone cannot do the job well. By adding magnesium, the muscles relax much more easily and more thoroughly.
Deficiency of magnesium is associated with weak muscles and muscle spasms.
Anti-helminthic (or parasite remedy). Magnesium helps the body to rid itself of all types of parasites. This is one of its effects upon the large intestine, especially.
A deficiency of magnesium is often found in those who contract parasitic infections. Plenty of magnesium in the body is protective against some parasite invasions.
Anti-psychotic. Magnesium helps a person keep calm, and can even help maintain sanity. When magnesium is low, one has a much greater chance of developing psychoses such as certain types of schizophrenia.
Anti-seizure. Magnesium helps prevent seizures. A deficiency of magnesium, along with a calcium deficiency, greatly increases the chances of developing epilepsy or a seizure disorder.
Promoting hormone production, secretion and activity. Magnesium is needed in the pituitary and other glands to help produce a number of pituitary hormones. It also helps produce other hormones, such as thyroid hormone and adrenal hormones.
In addition, none of the body’s hormones can function well without magnesium. Deficiencies of magnesium and other minerals are associated with many hormonal-related imbalances and diseases.
Protein synthesis. Magnesium also plays important roles in the nucleus of every cell. Here it is involved in the complex process of synthesizing all of the chemicals the body needs every day. This process is also called biosynthesis.
Deficiency slows protein and other biosynthesis, which impacts the entire body and leads to aging, DNA telomere shortening and many other problems.
Bone health. Magnesium is very important for the bones. This is not taught nearly enough in medical school. Magnesium always balances and assists the action of calcium, and while there is less magnesium in the bones, its role is very important there.
Deficiency causes weakened bones, bone spurs, osteoporosis, pathological fractures, and can contribute to bone cancers.
An alkalinizing agent. Magnesium has an alkaline effect on the body. This is very important because today most bodies are too acidic due to nutrient deficiencies and too many toxic metals and toxic chemicals.
Deficiency of magnesium contributes to an acidic body, which predisposes a person to many serious health conditions.
An important transmuting element. Magnesium participates in a number of important transmutations, providing that a person is healthy enough to accomplish the transmutations.
Magnesium deficiency reduces the body’s ability to transmute certain elements, and this impacts health negatively in many ways.
Other common symptoms that may be due to a magnesium deficiency are anger, belligerence, and pain such as fibromyalgia due to muscle tension. Others include asthma, migraines, fatigue, acute muscle spasms, upper respiratory infections, chronic sinusitis, seasonal allergies, rhinitis, and most cardiovascular disease.
DEVELOPMENT REQUIRES A LOT OF MAGNESIUM
We do a lot of research to find out how to cause development to occur as fast and as smoothly as possible. One finding is that it requires many types and a large amount of magnesium.
To obtain the magnesium needed, we must be very careful with the diet, the drinking water, the salt intake, and we also must use magnesium supplements. This is discussed below.
These are a must for everyone today. Common forms of supplements are citrates, chelates, oxide, hexaniacinate and glycinate.
A placeholder. It is critical to understand that magnesium supplements such as chelates, citrates or others function mainly as placeholders. This means they “fill in” or act as substitutes, but are not the correct forms the body needs. The body replaces them when it obtains enough of the correct forms of magnesium, either from food sources, such as well-cooked vegetables, or thanks to the work of the controller creatures (see below).
Magnesium supplementation on development programs. All adults on a development program need about 400 mg of a magnesium supplement. It is always mixed with calcium for balance.
Children get less, but they all get some, including babies starting around age 4-6 months.
Those with a hair tissue magnesium level greater than about 20 mg% may benefit from a little more magnesium because the magnesium in the tissues is often somewhat biounavailable.
Those with a Four Lows hair mineral pattern need a lot more magnesium – up to about 1500 mg daily of magnesium. This may seem excessive, but Dr. Eck found it is the only way to move some people out of a four lows mineral pattern.
Other Magnesium Supplements
Epsom salt baths. Epsom salts contain magnesium sulfate. This form of magnesium is not a good one, but it is easily absorbed and will temporarily relax the body. It is also not too harmful if used in a bath only occasionally, up to once or twice a week, at the most.
We rarely need to recommend Epsom salt baths, although they are relaxing.
Topical or transdermal magnesium. Some books and doctors advise people to rub magnesium oil on the skin. This is very dangerous! It gives a quick symptomatic effect that can reduce muscle pain, fibromyalgia and perhaps alleviate fatigue. However, it is a stimulant that seriously unbalances the body and can lead to a heart attack or stroke.
Transdermal magnesium lowered the sodium/potassium ratio of one of our clients. After a few months of it, he had a severe stroke. Another client used it previous to our program and had a heart attack. Please do not use it. For details, read Transdermal Magnesium.
Intravenous and intramuscular shots of magnesium. Hospitals use a lot of intravenous (IV) and intramuscular (IM) magnesium. It is one of the best things they use, because it is basically a nutritional solution for situations such as eclampsia and pre-eclampsia, heart attacks and some other emergencies.
Some holistic doctors and naturopaths give intravenous magnesium with other vitamins and minerals, such as the Myers Cocktail, to replenish the body’s magnesium.
While it can improve symptoms of fatigue, fibromyalgia, and other conditions, it has several problems that make it unacceptable for a development program. These problems are 1) yin, 2) temporary, 3) a shotgun approach.
Yin means that it subtly unbalances the body in a very harmful way over time. One or two treatments is not a problem, and indeed helps some who are very nutritionally depleted. However, when continued, the body gradually becomes more yin, which is very harmful. For more, please read Yin Disease on this website.
Temporary means that the beneficial effects of intravenous magnesium tend to wear off after a few days to a few weeks. This tells us the magnesium shots or IVs fill a need, but they do not, on their own, restore the mineral balance.
A shotgun approach means that magnesium is not carefully measured and given in the exact dosage needed. Instead, one just loads up on it, hoping it will have the desired effect. Doctors even call it a “magnesium push”.
Indeed, giving any mineral intravenously or intramuscularly bypasses the way the body normally controls how much of a substance it absorbs. This is always more dangerous, as one can easily overload the body.
For all these reasons, the only time we would recommend intravenous magnesium is the way it is used in emergencies in the hospital. We do not need and would never recommend intravenous or intramuscular magnesium in an ongoing way, as many naturopathic and holistic doctors offer. We do not find it necessary and it can easily do more harm than good.
LIFESTYLE AND MAGNESIUM
Stress and too much exercise use up magnesium quickly. Very few sports drinks replenish it in great enough quantity, for instance. Diarrhea can also deplete magnesium if it continues for a week or more.
Magnesium is primarily an intracellular mineral. Measuring it in the blood serum is therefore not usually as good as measuring it inside the cells.
The body maintains the magnesium level in the blood serum quite steady, even in the face of great deficiency. Magnesium is robbed from the tissues to do this. Therefore, the serum magnesium level is not a good indicator of magnesium deficiency or excess.
RED BLOOD CELL MEASUREMENT
Some holistic doctors measure magnesium in the red blood cells. This is a cellular measurement that is better to identify deficiencies than serum measurement. However, we don’t need or recommend red blood cell measurement because we find that everyone is low in magnesium.
HAIR MINERAL ANALYSIS
One cannot identify a magnesium deficiency or excess from a hair sample. As stated earlier, we find that everyone is deficient in magnesium today.
However, the hair magnesium level and ratios provide a lot of information about magnesium metabolism and other aspects of health and disease and psychological qualities of the body. Among other things, we use the hair tissue magnesium level to help assess:
- the oxidation rate
- adrenal gland activity
- sugar tolerance
- lifestyle imbalances
The ideal level. The ideal hair magnesium level we use is 6 mg% or 60 parts per million.
Fast oxidizers have lower levels of magnesium in the hair in relation to the levels of sodium and potassium. Fast oxidizers with a sodium/potassium ratio less than 2.5 require the most supplementary magnesium, regardless of the hair magnesium level.
Slow oxidizers have a higher hair level of magnesium in relation to the level of sodium and potassium.
Biounavailable magnesium on the hair analysis. When magnesium is above about 10 mg% in the hair, some of it is biounavailable and usually in an oxide or another ‘amigo’ form. These compounds of magnesium are very irritating, not as alkaline-forming, and pro-oxidant. As a result, they damage body tissues.
‘Amigo’ magnesium cannot participate in many enzyme reactions. Instead, it just builds up in the tissues exactly like a toxic metal. This is why we say it is biounavailable – meaning unavailable for use in many enzymes.
However, it is part of a defense mechanism of the body. When the adrenal glands are depleted and toxic, the irritating quality of these magnesium compounds stimulates adrenal gland activity that is necessary to maintain life.
Biounavailable magnesium is a problem for millions of people. Symptoms of this imbalance may include fibromyalgia and other types of pain, irritability, insomnia, muscle weakness, depression, muscle cramps, especially after exercising, and possibly others.
Magnesium is involved in a number of important hair mineral patterns. These include:
- Belligerence pattern (magnesium less than 4 mg%).
- A magnesium shell pattern.
- Carbohydrate intolerance - when the calcium/magnesium ratio is between 9.5 and 13.5. (See The Calcium/magnesium ratio.)
- Spiritual defensive pattern or lifestyle imbalance pattern – when the calcium/magnesium ratio is greater than about 13.5.
- Three highs/four highs patterns
- Three Lows/Four lows patterns
- Double low ratio pattern, also called double give-up and a slow death pattern.
- Double high ratio pattern, also called double inflammation and at times, the hard driver pattern, which is a criminal pattern.
- Getting a controller pattern. This is a rise in the hair magnesium level of at least 40% or more on a retest. In most instances, the cause for this is the elimination through the hair of inferior magnesium compounds and their replacement with better forms of magnesium in the body. This interesting phenomenon is discussed later in this article under the heading of The Three Types Of Magnesium.
- Magnesium also is part of settling down pattern, coming alive pattern, bowl pattern, hill pattern, bowling pattern, hilling pattern, step-up pattern, step-down pattern, trying hard to stay afloat, wasting your time, extreme lifestyle stress, stress from within and without, working your way out of four lows, digging deeper, facing your issues, surges or explosions, mother-issues, father-issues, anchors, pivots, and all the variants of these and the patterns above.
THE MAGNESIUM BODY TYPE AND PERSONALITY
Magnesium is a very light, very strong metal. It is a ‘female’ mineral and we call magnesium the bright and shining mineral because it burns very brightly. Joseph Scogna calls magnesium quiet strength. Magnesium is also strongly alkaline-forming. This all gives clues to the magnesium personality and body type.
Recall that everyone is a mixture or ‘alloy’ of many minerals. However, in some people magnesium predominates.
Physical qualities. The bone structure (calcium) is often somewhat weak and delicate. Magnesium and calcium oppose or antagonize one another.
Magnesium people are usually rather tall and slender. This is due to thyroid and pituitary dominance rather than adrenal dominance, which is associated with calcium (see the article Calcium).
Magnesium-dominant people are often very slower oxidizers. This can be somewhat upsetting to see, but magnesium personality people handle very slow oxidation very well without much depression, arthritis or other symptoms. The reason may be that they can maintain an alkaline body chemistry more easily due to their higher magnesium level.
Magnesium-dominant people are quite the opposite of calcium-dominant ones, who are usually shorter, stockier, with heavy bones and often a coarser persona.
Mental/emotional qualities. Magnesium personalities tend to be more feminine (in a man or woman), and very bright and smart. They are usually rather quiet and gentle people.
Spiritual/development. The physical build and personality of the magnesium personality type strongly favors rapid development. A slender body makes it easier to move subtle energy through it.
A quieter personality makes one more receptive to resting and doing the pulling down exercise which is required for development. Also, the gentler magnesium personality is less interested in sex. This helps a person retain their sexual fluid, another requirement for rapid development.
THREE TYPES OF MAGNESIUM COMPOUNDS
1. Superior magnesium. This is the magnesium obtained from the high-quality food sources discussed above. Also, certain creatures called the controllers are able to bring excellent forms of magnesium to a person as part of their assistance effort. This is a great gift. To understand this better, read The Controllers.
In some people, one or two of the four controller creatures are not present. This commonly occurs if one experiences trauma such as a rape or beating, has a severe accident, or if one becomes too nutritionally depleted. The person often feels more tired, and somewhat directionless.
A development program will, in every case, eventually bring these creatures back to a person’s body. To bring them back, the body must be made more yang, and it must become much better nourished. Also, at times, the trauma needs to be undone, which also can occur with a development program.
One can make an educated guess that one or more controller souls has returned to a body if:
1. The person is following a complete development program for at least two to six months.
2. The hair magnesium level rises at least 100% on a retest.
3. Usually the magnesium rises without as much of a rise in the hair calcium level.
4. One may feel better, with more energy and a better sense of direction in one’s life.
The rise in hair tissue magnesium is actually an elimination of less bioavailable magnesium due to the efforts of the controller souls. This results in a higher energy level and better overall health.
2. Inferior magnesium compounds. These are the forms of magnesium found in some foods, and in magnesium supplements. They function to some extent, but cannot produce excellent health. They are placeholders, only.
3. Toxic “amigo” magnesium (an oxide form). Many people’s bodies have too much magnesium, but it is not a healthful for of magnesium. It is in an oxide or other irritating form. This is called an “amigo” form on this website.
Oxides are not the best forms of minerals. They are irritants and oxidants, and do not perform as well in most enzymes.
Oxides and other toxic forms of magnesium interfere with calcium metabolism and can be irritating to the tissues.
The oxide form also slows or even stops development if too much is present.
A hair analysis cannot clearly detect which form of magnesium is present in the body. However, whenever the hair magnesium level is above about 10 mg%, usually there is some of the oxide form in the body. A development program is one of the few ways we are aware of to remove this toxic form of magnesium from the body. For more details, read Iron, Manganese, and Aluminum - The Amigos on this website.
Alkaline. Magnesium is an alkaline earth mineral with a valence of +2. This means that it has an alkaline reaction in the body.
A feminine mineral. However, both men and women need plenty of it, however.
Joseph Scogna calls it “the lion” or “contemplation of power”. These nicknames may be helpful to understand what magnesium does in the body.
A powerful laxative. Magnesium that is not absorbed has a powerful laxative effect. The magnesium attracts too much water into the intestine, and this is what causes the diarrhea. We occasionally recommend magnesium as a laxative because it is less toxic than laxative herbs.
USES FOR MAGNESIUM IN INDUSTRY
Magnesium is a very lightweight and very strong metal. As a result, it is used to make aircraft parts, lightweight bicycle frames, and lightweight frames for eyeglasses, among other things.
Magnesium is also used to make flares and fireworks because it gives off a very bright light when it burns.
Magnesium has many other uses in industry, mainly as a component in a number of alloys that must be light in weight and very strong at the same time. These include aluminum alloys, for example, used in aircraft.
These are similar to those for calcium. They include vitamins A, D, E, K and perhaps a few others. Vitamin D, for example, appears to assist magnesium metabolism, not just calcium absorption. Vitamin B6 or pyridoxine has a close relationship with magnesium. Magnesium is thought to help vitamin B6 to be incorporated into some enzymes.
Vitamin B1 or thiamin is a synergist with magnesium in glucose metabolism. Vitamin C is a synergist in connective tissue synthesis. Tetraiodothyronine or T4 increases cellular magnesium levels. In fact, many nutrients are synergistic with magnesium because magnesium is involved in almost all body functions.
Magnesium antagonists include calcium, sodium, potassium, phosphates, fluoride, all toxic metals and others. Alcohol severely depletes magnesium. This is due, at least in part, to the fact that metabolizing alcohol uses up many magnesium-dependent enzymes. This requires them to be reconstituted, using up a lot of magnesium. Alcohol is also a diuretic that can remove magnesium from the body through the kidneys.
Diarrhea, especially if it lasts more than two days, depletes magnesium because there is a lot of magnesium in fecal matter.
Soda pop and sugar in the diet lower magnesium levels. These contain phosphorus compounds that bind firmly to magnesium, along with calcium and zinc, and tend to remove these minerals from the body.
Soda pop is among the worst magnesium robber. Some of the ‘high’ that one gets from drinking soda pop is actually magnesium depletion that causes a form of anxiety and irritability. Even the high phosphorus content of meat, eggs, cheese and other animal proteins lowers magnesium to some degree, but not that much because these foods contain some magnesium.
Exercise. Vigorous exercise uses up some magnesium. This contributes to leg cramps, shin splints and other symptoms that come with exercise. It can explain the ‘high’ of exercise, to some degree, as well.
Ionizing radiation lowers the body’s magnesium level significantly. It is not usually noticeable unless exposure is chronic and intense. Taking extra magnesium before radiation treatments may help protect one from some of the damage due to radiation therapy.
