Calming Your Life & Tinnitus with Magnesium
by Barry Keate
Magnesium may be the most commonly deficient mineral in human nutrition. It is known as a calming or anti-stress mineral and is very important to many human functions. Magnesium is a mineral needed by every cell of the body. About half of the body’s stores are
found inside cells of body tissues and organs, and half are combined with calcium and phosphorus in bone.
Only 1 percent of the magnesium in the body is found in the blood. The body works very hard to keep blood levels of magnesium constant. Because the body easily eliminates excess magnesium, toxicity is nearly
unknown, although an excess can cause loose stools or diarrhea.
Deficiency is quite common and can lead to muscle cramps, fatigue,
irritability, and insomnia.
The key body functions of magnesium are:
- Relaxes the muscles, including the heart;
- Works in concert with enzymes to carry out metabolic functions,
including protein synthesis, energy production, and neuromuscular
function;
- Used for anxiety, high blood pressure, poor sleep, asthma attacks, menstrual and muscle cramps, and abnormal heartbeats.
Eat Your Green Veggies
Green vegetables such as spinach provide magnesium because the center of the chlorophyll molecule contains it. Nuts, seeds, and some whole grains are also good sources of magnesium. Although magnesium is present in many foods, it usually occurs in small amounts. As with most nutrients, daily needs for magnesium cannot be met from a single food.
Eating a wide variety of foods, including five servings of fruits and vegetables daily and plenty of whole grains, helps to ensure an adequate intake of magnesium. The magnesium content of refined foods is usually
low. Whole-wheat bread, for example, has twice as much magnesium as white bread because the magnesium-rich germ and bran are removed when white flour is processed.
Doctors will measure blood levels of magnesium whenever a deficiency is suspected. When levels are mildly depleted, increasing dietary intake of magnesium can help restore blood levels to normal. Eating at least
five servings of fruits and vegetables daily, and choosing dark-green
leafy vegetables often, as recommended by the Dietary Guidelines for
Americans, the Food Guide Pyramid, and the Five-a-Day program, will help
adults consume recommended amounts of magnesium. Magnesium tablets also
may be prescribed, but some forms, in particular magnesium salts, can
cause diarrhea. When in doubt, a doctor or qualified healthcare
provider can recommend the best way to get extra magnesium when it is
needed.
Protection of the Inner Ear
Magnesium
also protects the nerves in the inner ear and is a powerful glutamate
inhibitor. Glutamate is a neurotransmitter, produced by the action of
sound waves on the hair cells of the inner ear. The unregulated
production of glutamate at sound frequencies for which there is no
external stimulation is the cause of tinnitus.
Dr. Michael Seidman,
in his excellent article, “Medicines to Treat the Inner Ear” states;
“Decreased blood supply causes significant stress to the nerve tissue
(of the inner ear) by causing the production of free radicals. (Author’s note: The major causes of tinnitus all result in decreased blood supply.)
These molecules are extremely damaging and are known to be responsible
for over 100 human disorders. The accumulation of free radicals severely
damages the inner ear and other tissues. Through a complex chain of
events, this damage can then cause a release and accumulation of
glutamate and calpains. These chemicals in high concentrations are
extremely destructive to the body.
“Studies have shown that excessive glutamate may play a role in the
production of tinnitus. Studies also show that glutamate antagonists can
have a protective effect on the inner ear and possibly be a treatment
for peripheral tinnitus, which is generated by the inner ear. Three
such drugs are currently under investigation at the Henry Ford Health
System for tinnitus, including magnesium.
“The protective effect of magnesium in preventing noise-induced
hearing loss has been studied since it was found that magnesium in inner
ear fluid decreases significantly after intense noise exposure. The
results of one placebo-controlled study showed that subjects who took
oral magnesium supplements displayed a significantly lower incidence of
noise-induced hearing loss compared to the control group. In 1998 a
highly motivated patient elected to undergo a catheter-delivered
infusion of magnesium sulfate to the round window (of the inner ear).
Within 60 seconds of the infusion, she experienced complete resolution of
her tinnitus. This effect lasted until the flow of medication was
discontinued 48 hours later.”(1) Another clinical trial of magnesium
found that “Magnesium… exhibit(s) a statistically significant
oto-neuro-protective action (inner ear protection) in noise-induced
hearing loss and tinnitus.”(2)
Blood Pressure Reduction
Several clinical trials show magnesium has a positive
effect on reducing elevated blood pressure levels. High blood pressure,
high cholesterol, and stress are three of the primary aggravators of
tinnitus. One study concludes, “Our meta-analysis detected
dose-dependent blood pressure reductions from magnesium
supplementation.”(3) Another found “. . .calcium and magnesium may
represent important components in the combination diet of the DASH
study. It seems that it is the combination of these nutrients that is of
crucial importance for the achievement of optimal blood pressure reduction.”(4) Finally, a third study states, “These findings suggest that Magnesium supplementation prevents blood pressure elevation. . .
“(5)
Magnesium is very helpful in combination with calcium. Dr. Seidman
also states, “Calcium supplementation has been shown to improve tinnitus
symptoms in certain patients. In conjunction with magnesium, calcium
also plays a vital role in the regulation of electrical impulses in the
central nervous system.”(6)
These products can be easily found on health food store shelves and
are quite inexpensive. A recommended daily dosage is 400 mg of magnesium
and 1,000 mg of calcium. Magnesium can be taken in therapeutic doses of up to
600 mg daily. Because magnesium causes smooth muscle relaxation, it can
loosen the bowels. If this happens, reduce the dosage a little.
