The complex symptomatology
Magnesium deficiencies may be observed in
the most diverse forms, ranging from migraine attacks to the unpleasant plantar and toe
Magnesium Supplementation under Medical Supervision
A distinction is made between two different forms of oral magnesium supplements:
1. Substitution therapy (magnesium deficiency)
2. Utilization of the pharmacological properties ( no magnesium deficiency)
A distinction is made between two different forms of oral magnesium intake. Firstly, replacement therapy, in order to compensate for deficiency. And, high dose magnesium administration, which takes advantage of the pharmacological effects of the mineral, independently of magnesium deficiency.
The Pharmacology Of Magnesium
As a bivalent cation, magnesium tends to form chelates (from the Greek chele = crabs claws).
The most important intracellular binding partner is ATP (adenosine triphosphate). Via chelation, large number of ATP-dependent enzymes, i.e. which promote cellular metabolism, are activated.
The First Effect Of Magnesium
Its enzyme cofactor function
The magnesium ATP complex
Owing to the magnesium ATP complex, magnesium acquires a decisive influence over metabolic reactions which use and supply energy. What is more, since the membrane-bound sodium-potassium pump is ATP-controlled, the electrolyte balance of all cells is dependent on magnesium.
There is nevertheless scarcely any outside influence on this intracellular effect, which is therefore not in the foreground of pharmacodynamic considerations.
The Second Effect Of Magnesium
Neutralization of negative charges
The extracellular effect of chelation is, however, interesting: the bivalent, positive magnesium neutralizes negative charges on the outer side of the cells, thereby increasing the potential difference between the inner and outer side of the cell membrane.
As a result, the excitation threshold (and therefore the resting potential) increases and the muscles are not so readily excitable.
In the heart, magnesium reduces arrhythmias.
In skeletal muscle, cramps are less frequently triggered.
In the uterus, premature contractions can be suppressed.
The magnesium ion (Mg 2+ ) is larger, in its hydrated state, than the calcium ion (Ca2+ ) and is therefore capable of displacing the latter.
This calcium antagonism acts centrally on both muscle and nerve cells: the magnesium ion occupies the calcium binding sites on muscle cells, thereby displacing calcium into the calcium channel without undergoing the same migration itself.
The blood vessels dilate.
The oxygen balance of the cells is improved - on the one hand,
via an increased supply and on the other hand via lower consumption.
The Fourth Effect Of Magnesium
Inhibition by Magnesium of the Release of Neurotransmitters
Inhibition of calcium - induced neurotransmitter release
Magnesium inhibits calcium - induced neurotransmitter release at the nerve cell level, or to be more precise, at the level of the presynaptic membranes of the sympathetic nervous system.
The excitability of the nerve cells is diminished; among other
things, adrenaline and noradrenaline release is reduced (important in heart disease and
The Use Of Magnesium
Indications for magnesium
The area of application for magnesium has always been derived from its pharmacology, the muscle and muscle cell:
In cardiology, magnesium is administered in coronary heart disease and cardiac arrhythmias.
In gynecology, magnesium is employed orally, in order to cover the increased requirements during pregnancy and lactation and as therapy for dysmenorrhea (cramp-like lower abdominal pain) and premature contractions.
In eclampsia, (suddenly occurring life-threatening cramps during pregnancy, labour or child bed), parenteral administration is chosen.
Neuromuscular disturbances throughout the whole body are grouped together under the name "tetanic syndrome." This includes, in addition to muscle contractions and gastrointestinal spasms, calf, foot and toe cramps. These are symptoms with which the patient often visits the physician and for which a high-dose magnesium preparation provides the ideal remedy.
Migraine is also included in this area. In migraine, high - dose magnesium is employed as long - term prophylactic treatment: in a recent study, 600 mg of magnesium per day as magnesium citrate brought a significant reduction in the frequency of attacks (-41%) and the number of migraine days (-49%).
In digestive problems, a side - effect of magnesium becomes a "virtue": at high doses, magnesium has a laxative effect. Pregnant women in particular therefore value magnesium as a mild, pain - free laxative.
