Magnesium: why is it so importrant?

Magnesium is a mineral salt essential to the proper functioning of the body. This trace element intervenes in particular in the regulation of the cardiac rhythm, in the functioning of the muscles and in the transmission of the nerve impulses. It is found in many foods, including chocolate!

What is it used for ?

Magnesium is partly combined with calcium and phosphorus, especially in the bones. It is mainly in the bones, teeth, but also in the muscles and the liver. It is also present in each of our cells, involved in many metabolic reactions of the body.

Magnesium plays an important role in the transmission of nerve messages and in the functioning of muscles (relaxation).

To prevent cardiovascular disorders, diabetes

Adequate magnesium intake is recommended to prevent certain cardiovascular disorders (abnormal rhythm, and possibly high blood pressure). It would intervene in the regulation of the sugar level in the blood (glycemia).

Magnesium is also known for its properties against states of nervousness, anxiety ...

The recommended daily intake of magnesium is 320 mg for women, and about 400 mg for men, pregnant or breastfeeding women.

A deficiency of magnesium causes:

  • tiredness,
  • a drop in appetite,
  • nausea,
  • Cramps...

A lack of magnesium can also promote heartbeat disorders.

The people most exposed to a lack of magnesium are:

  • People playing sports and eating poorly,
  • Old people,
  • People who drink too much alcohol,
  • Patients suffering from chronic digestive problems,
  • Patients taking certain medications such as those against blood pressure (diuretics).

And the excess in magnesium?

Indeed, an excess of magnesium in the body can also have consequences for our state of health.

An excess of magnesium can result in:

  • digestive disorders (diarrhea),
  • a drop in blood pressure,
  • a brutal fatigue.
An excess of magnesium rarely occurs: especially during prolonged and excessive intake of magnesium-based dietary supplements.

People with renal insufficiency are much more likely to have elevated levels of magnesium, and should avoid taking magnesium supplements.
