Magnesium is indispensable to the human body and must be supplied daily in sufficient quantities.
A healthy adult has about 20 grams of magnesium in his body. To prevent a magnesium deficiency, you should take daily 300 mg of magnesium.
It occurs in many foods and in drinking water. Especially in dairy products, whole grains, meat, nuts and various types of fruit, the essential substance magnesium is included.
It is taken into the bloodstream via the small intestine and metabolised by the kidneys and excreted. Magnesium is involved in about 300 enzyme reactions, in addition, free magnesium ions have an influence on the membrane potential of the cells. They serve as an antagonist of calcium and maintain the resting potential of the muscle, heart muscle and nerve cells. They inhibit the transmission of stimuli from the nerves to the muscles. This can prevent muscle spasm and slow down the heartbeat.
There are three different reasons why magnesium deficiency can occur.
Magnesium is, as mentioned above, involved in many functions in the body, which is why several symptoms can occur simultaneously in a deficiency syndrome.
Symptoms of magnesium deficiency syndrome include:
The last large nutrition study in Germany showed that just under 40% of the German population does not consume enough magnesium. About 10-20% of Germans suffer from a persistent mild magnesium deficiency, which can be compensated by the kidney and the small intestine in full health.
To prevent or treat a magnesium deficiency, magnesium can be prescribed. It should help to regulate the muscle activity, provide the body with more energy and rebuild the cell walls. Magnesium supplements from Biolectra are ideal.
Magnesium as a drug should not be taken in people who suffer from severe renal impairment and conduction disturbances of the heart (eg: AV block).
Even with an already occurring hypersensitivity to a magnesium drug, no tablets should be taken.
Even with mild and moderate renal impairment, as well as with the use of gastric acid-binding agents or laxatives and in the case of mild kidney stones, magnesium intake should only be carried out under the strict control of the physician. Pregnant women can take magnesium.
If given shortly before birth, the newborn should be monitored for at least 24 hours, preferably 48 hours. Children can also get magnesium. Depending on the preparation, there is a maximum dose for children.
Everybody reacts differently to medicines. The following side effects may or may not occur. Depending on the type and frequency of taking a drug, adverse effects may be different.
If magnesium is taken orally as a tablet, effervescent tablet or capsule, it can often come to soft chairs. If diarrhea occurs, treatment with magnesium should be stopped for a short time. With a minimized daily dose, the medication can continue, provided that the bowel movement has normalized.
In case of impaired kidney function, a prolonged intake may lead to increased daytime fatigue. The medicine should be temporarily discontinued and a reduced dose should be taken after a break.
If magnesium tablets are taken as part of a magnesium deficiency, diarrhea, among other things, can occur as a known side effect.
Diarrhea, also known medically as diarrhea, may also be a sign of overdosage with magnesium salts in the context of magnesium intake.
But there are also people who are so sensitive that they tend from the normal recommended daily dose to the appearance of soft chairs to diarrhea.
If, when taking magnesium supplements, there is an increased incidence of thin stools or diarrhea, there are several ways to reduce them or to avoid them altogether. First, you can try to reduce the daily dose. Even a smaller daily amount of magnesium may cause the number of diarrhea to fall or even disappear completely.
Another option is to stop taking magnesium supplements instead of taking a reduced amount of magnesium. In particular, the intake of magnesium at bedtime is recommended. If diarrhea occurs when taking magnesium, another option is not to take the entire daily amount at one go, but to spread it over several smaller portions throughout the day.
The body may be able to completely absorb the magnesium from the intestine.
The occurrence of diarrhea when taking magnesium supplements is easy to explain:
Magnesium is taken by mouth. It then passes through the stomach into the intestinal area, where it is to be absorbed by the intestinal mucosa. In the mucous membrane, there are small channels for this, through which the magnesium enters the bloodstream. However, the channels have a limited capacity. If this is exceeded, the complete magnesium can not be taken up by the mucous membrane so that a part remains in the intestinal lumen and is excreted with the stool. However, the problem is that high levels of magnesium inside the intestine cause more water to be drawn into the intestine. This mechanism causes the body to excrete more water into the intestine, which makes the stool softer and more fluid, leading to diarrhea.
Therefore, you should always drink a lot when taking magnesium, because the body is deprived of water. This is a useful side effect in the elderly. These often suffer from constipation (medical: constipation called) or take medication that cause constipation.
The tolerability of the various magnesium preparations can be very different from person to person. Therefore, it is possible that you get diarrhea from one preparation, but not from the other. Therefore, a change of the drug can help as soon as diarrhea occurs.
Depending on the type of drug interactions can occur. Oral magnesium should not be taken at the same time as antibiotics from the active ingredient group of aminoglycosides, tetracyclines or penicillins. They prevent each other's absorption into the bloodstream. Magnesium should be taken three to four hours offset to minimize the risk of ingestion. If you also take iron tablets, you must be careful, because the absorption of iron is also disturbed by magnesium. If you are suffering from a rhythm disorder and are taking anti-arrhythmic drugs such as quinidine, you should not take magnesium medications.
Taking concomitant cardiac glycosides against existing heart failure, isoniazid in tuberculosis or certain psychotropic drugs will prolong the uptake of the above-mentioned drugs into the bloodstream by magnesium. If you have kidney dysfunction and are also taking laxatives, calcium-containing medications, or potassium-sparing dehydrators, magnesium can lead to increased blood levels of calcium and magnesium. If magnesium is injected into the vein, respiratory activity may be inhibited, provided that sedatives or anesthetics are administered at the same time. Magnesium, administered into the vein, enhances the effects of antihypertensive drugs and muscle relaxants.
