What are the magnesium effects on heart rhythm? Does magnesium help the heart keep a good rhythm? How much magnesium is enough daily for an adult? Can it cause bradycardia? And finally, what are the potential side effects of magnesium?

I. What is Magnesium

Magnesium is one of the most abundant minerals in the body. It is essential to life, as it is involved in over 300 metabolic reactions in our bodies.

It is found in foods such as cocoa, nuts, cereals, seafood, and fatty fish.

But a small part is stored in the body, more precisely in the bones and muscles.

Magnesium also plays an important role in the nervous system, in the concentration or relaxation of muscles, and has significant effects on the heart rhythm.

II. Magnesium effects on heart rhythm

# is magnesium good for heart arrhythmia

Magnesium is indeed a very good treatment to fight against many heart diseases.

It acts as a preventive measure against a number of heart diseases, including cardiac arrhythmia and stroke.

# Does Magnesium Help the Heart Keep the Beat

Despite its many benefits, magnesium also plays an important role in regulating heart rhythm.

It allows the heart to keep a normal rhythm, between 60 and 100 beats per minute, thus preventing various heart diseases.

# Magnesium and heart disease

Heart diseases are disorders that affect the heart and all blood vessels.

It can be a heart rhythm disorder, high blood pressure or heart failure, and many other things.

Since magnesium helps regulate the heart rhythm, it also helps fight against these different diseases.

In particular, the lack of magnesium can cause high blood pressure, a little severe, in the long term!

# how long does it take for magnesium to work for heart palpitations

When you have abnormal heart palpitations and you take magnesium to remedy them, the ideal is to consume 300mg/day for 2 to 3 weeks to observe considerable improvements.

Magnesium does not work instantly on heart palpitations. It is necessary to take it continuously over a period of time of at least two to three weeks to observe the changes.

# Can too much magnesium cause irregular heartbeat?

Excess magnesium in the body can cause neuromuscular symptoms, chronic diarrhea, nausea, headaches, and, in extreme cases, muscle paralysis.

However, there are also much more serious risks, such as certain heart rhythm abnormalities like heart failure or high blood pressure

# Which arrhythmia is treated with magnesium?

As mentioned above, magnesium is involved in the regulation of heart rhythm. It, therefore, helps to fight against heart disease.

However, magnesium is not effective in all cases. For example, in the case of ventricular fibrillation, magnesium has no role to play. It is essential to seek emergency treatment.

III. How Much Magnesium Is Enough?

For an adult, the recommended amount of magnesium is 6mg/kg/day. This means that for a woman weighing 60kg, for example, it is advisable to take about 360mg/day and for a man weighing 70kg, 420mg/day will be sufficient.

It is sometimes difficult to measure and respect this dose. It is therefore advisable to have a balanced and varied diet and to take magnesium supplements only when necessary, in case of magnesium deficiency.

IV. What magnesium is best for heart palpitations?

Consuming magnesium has restorative effects on the heart rhythm. However, for more effectiveness, it is often recommended to use magnesium glycerophosphate.

This is a form of magnesium known for its good intestinal tolerance. It is often associated with taurine and/or vitamin B6 and allows for an effective supply of magnesium, phosphorus, and glycerol.

Magnesium glycerophosphate is therefore the magnesium par excellence for heart palpitations. It is very effective and has practically no side effects after consumption.

V. Does magnesium cause bradycardia?

Magnesium used in the right dosage does not really have any harmful effects on the body. However, when an overdose of magnesium is taken and there is an excess of magnesium in the body, the number of heartbeats between 60 and 100 beats per minute at normal can decrease to less than 60 beats per minute.

This is called bradycardia and is triggered by magnesium. Magnesium can therefore be the cause of bradycardia, although cases are very rare! 

VI. Can magnesium cause heart block?

A heart block is a heart rhythm disorder, an arrhythmia. It occurs when there is a slowing down or interruption of the electrical signal coming from the upper chambers of the heart.

The question that arises is: can magnesium, which is supposed to ensure the proper functioning of the heart rhythm, trigger a heart block?

The answer to this question is yes. This can happen if magnesium is taken in excess, and it will then cause changes in the heart rhythm and therefore a heart block if necessary.

VII. Can magnesium slow your heart rate

Magnesium is also involved in the regulation of the nervous system. It has a sedative or rather relaxing action on the nervous system.

It allows then by the same phenomenon to relax and to relax the whole body, being able to thus lead to the slowing down of the cardiac rhythm in the event of stress or vis-a-vis other situations being at the origin of an acceleration of the cardiac rhythm.

VIII. Who Is at Risk for Magnesium Deficiency?

Most of the time, magnesium deficiencies are mainly due to low dietary intake of magnesium and are sometimes related to the level of sports activity of the individual.

The magnesium deficiency nowadays widely observed in the world is due to the exclusion of chocolate, nuts, and even almonds from the diet of some people.

According to studies, 75% of men and women are affected. Whether adults, young people, old people, or children, magnesium deficiency can affect everyone.

IX. When to take magnesium supplements

It is recommended to take magnesium with meals. You can take it in 2 daily doses, one at noon and one in the evening, or you can take it in one dose, that is to say only once in the evening.

However, it is not advisable to take magnesium supplements at your own convenience. To avoid cases of hypermagnesemia, it is best to take magnesium when you feel the need, that is, only when you are in need of magnesium.

X. Magnesium Side Effects

Although it is rare, an overdose of magnesium can cause side effects.

An excess of magnesium (hypermagnesemia) can cause diarrhea, vomiting, and a drop in blood pressure (hypotension).

In the most severe cases, magnesium overdose can cause cardiovascular and kidney problems.

Risks When Taking Magnesium

On the other hand, too much magnesium in the body has toxic effects on the body.

Excess magnesium exposes the body to behavioral disorders, lethargy, confusion, cardiac disorders, and even cardiac arrest.

Individuals suffering from renal insufficiency are the most exposed to these effects.
