Mais… quel type de magnésium choisir ????

Magnesium Dossier, part 2 of 3; Following:Magnesium, an essential for health !!!

There are definitely too many types of magnesium available on drugstore and health food store shelves. The questions that we can ask ourselves in front of all this offer:re :

-Which one to choose?

-Are they all the same quality?

-Do they all have the same effect?

-Are they all absorbed in the same way?

-Why would I pay more for one magnesium than another Is there a real differencece?

-And how much should I take?

Here is what we will try to elucidate here..

Each magnesium has its effect!

On the one hand, there are some things that need to be clarified when we look at the labels on the bottles of magnesium. We find there, in general, the amounts of total magnesium salts, and the contents of elemental magnesium. What is to be considered in fact the content of elemental magnesium, and not the total quantity of magnesium..

Then another important concept is the bioavailability of the product. Bioavailability is the amount of a substance that is absorbed by the body. So not all magnesium is absorbed equally.le.

You can see in the table below the main types of magnesium, their elemental magnesium content, their functions and the bioavailability of each form.

How much should I take and when?

On the one hand, practitioners recommend taking the dose of magnesium just before going to sleep because it has a relaxing effect that helps the quality of sleep. You will also have to find your individual dose, because each person has their own intestinal tolerance. It is therefore recommended to start with the smallest dose, and gradually increase it each night. The day the stools soften, it will be necessary to reduce the dose to respect its intestinal tolerance. Once the lack is filled, the dose can be reduced again to maintain intestinal comfort, while filling the daily lack of this precious

Some people need more magnesium than the recommended doses of 6mg / kg bodyweight / per day, for example pregnant women, adolescents, the elderly, and athletes, people with chronic stress. So, depending on one's tolerance, it may take longer for the magnesium deficiency symptoms to wear


In summary, almost everyone needs a magnesium supplement! It remains to choose the right product, for the desired functions. We choose a good product, of quality, easily absorbable and well tolerable. Avoid low-end products, which will cause you more problems than good.


Great deal!
