Naturopathy : Magnesium
All human tissues contain small amounts of magnesium. The Adult human body contains about 25 gms. of this mineral. The greater part of this amount is present in bones in combination with phosphate and carbonate. Bone ashes contain less than one per cent magnesium. About one-fifty of the total magnesium in the body is present in the soft tissues, where it is mainly bound to protein. Next to potassium, magnesium is the predominant metallic action in living cells. The bones seem to provide a reserve supply of this mineral in case of shortage elsewhere in the body.
Biochemists call magnesium the " cool, alkaline, refreshing, sleep-promoting mineral". Magnesium helps one keep calm and cool during the sweltering summer months. It aids in keeping nerves relaxed and normally balanced. It is necessary for all muscular activity. This mineral is in activator for most of the enzyme system involving carbohydrate, fat and protein in energy-producing reactions. It is involved in the production of lecithin which prevents building up of cholesterol and consequent atheros-clerosis. Magnesium promotes a healthier cardiovascular system and aids in fighting depression. It helps prevent calcium deposits in kidneys and gallstones and also brings relief from indigestion.
Magnesium is widely distributed in foods. It is a part of the chlorophyll in green vegetables. Other good sources of this mineral are nuts, soyabeans, alfalfa, apples, figs, lemons, peaches, almonds, whole grains, brown rice, sunflower seeds and sesame seeds. The recommended dietary allowances for magnesium are 350 mg. per day for adult man, 300 mg. for women and 450 me. during pregnancy and lactation. Deficiency can lead to kidney damage and kidney stones, muscle cramps, arteriosclerosis, heart attack, epileptic seizures, nervous irritability, marked depression and confusion, impaired protein metabolism and premature wrinkles.
Chronic alcoholics often show a low plasma magnesium concentration and a high urinary output. They may, therefore, require magnesium therapy especially in an acute attack of delirium tremens. Magnesium has also proved useful in bladder and urinary problems and in epileptic seizure. This mineral together with vitamin B6 or pyridoxine has also been found effective in the prevention and treatment of kidney stones. Magnesium can be taken in therapeutic doses upto 700 mg. a day.
Magnesium plays an important role in at least 300 fundamental enzymatic reactions and for that reason is of vital importance in our health.
Magnesium is required for
Magnesium helps with formation of bone and teeth and assists the absorption of calcium and potassium. Where calcium stimulates the muscles, magnesium is used to relax the muscles. It is further needed for cellular metabolism and the production of energy through its help with enzyme activity It is used for muscle tone of the heart and assists in controlling blood pressure.
Together with vitamin B 12, it may prevent calcium oxalate kidney stones. It helps prevent depression, dizziness, muscle twitching, and pre-menstrual syndrome. It can help prevent the calcification of soft tissue and may help prevent cardiovascular disease, osteoporosis, and certain forms of cancer, and it may reduce cholesterol levels.
Magnesium assists the parathyroid gland to process vitamin D, and a shortage here can cause absorption problems with calcium.
Deficiency of magnesium
A severe deficiency caused by mal-absorption, chronic alcoholism, renal dysfunction, or the use of certain medications can cause neuromuscular manifestations, and personality changes can occur.
Many cardiovascular problems are indicated with magnesium in short supply and rapid heartbeats as well as fatigue, irritability, and seizure can occur. Insomnia, poor memory, painful periods, depression, hypertension and confusion may also indicative of magnesium in short supply.
It is used for the management of premature labor, and for the prophylaxis and treatment of seizures in toxemia of pregnancy. A deficiency may also be a contributing factor to incontinence in older people and bedwetting in children.
Dosage
The dosage underneath is the Recommended Daily Allowance (RDA), but be aware that this dosage is the minimum that you require per day, to ward off serious deficiency of this particular nutrient. In the therapeutic use of this nutrient, the dosage is usually increased considerably, but the toxicity level must be kept in mind.
Males 19-30 years 400 mg per day Males >30 years 420 mg Females 19-30 years 310 mg Females >30 years 320 mg.
In supplementation it is normally taken in dosages of 750 - 1,000 mg per day.
Toxicity and symptoms of high intake
If you have kidney or heart problems first check with your medical practitioner before taking a magnesium supplement as an over supply can in severe cases lead to coma and death.
Best used with
It is best taken with calcium, iron, B group vitamins as well as vitamin E.
When more magnesium may be required
It has been found that people under stress have low magnesium levels, indicating that magnesium may be beneficial to those under stress.
Enemy of magnesium
Consumption of alcohol, diuretics, high levels of zinc and vitamin D may increase your magnesium requirement. This will also apply if you are taking diuretics (water pills), have diarrhea or perspiring heavily as well as taking large amounts of vitamin C.
Other interesting points
Magnesium is being investigated for the treatment of migraine headaches.
Food sources
Magnesium is found in dairy products, fish, meat and seafood, as well as in legumes, apples, apricots, avocados, bananas, whole grain cereals, nuts, dark green vegetables, and cocoa, while hard water and mineral water may also supply it in fair quantities.
