The mineral magnesium is vital, but cannot be produced by our bodies. Therefore, it is vital to take it through food (and if necessary, food supplements such as Magnesium Verla, Biolectra or Magnesium effervescent tablets). Magnesium is found primarily in whole grain products, but also in mineral water, liver, poultry, fish, pumpkin and sunflower seeds, various nuts, chocolate, potatoes, spinach, kohlrabi, oranges, bananas, soft fruit, and milk and dairy products.
Magnesium preparations always provide magnesium in compounds, ie the magnesium is bound to another substance. In the compound magnesium oxide, for example, the mineral is bound to oxygen, while in magnesium carbonate it is present as a compound with the salt of carbonic acid. There are other compounds such as magnesium sulfate or magnesium citrate. The type of compound does not seem to play a role in the bioavailability and the speed of absorption. It is much more important that magnesium must be taken over a longer period of time in order to be used effectively by the body.
