Magnesium plays a role in many cellular functions, including those involving phosphoralations oxydaires, glycolysis, DNA transcription and protein synthesis.

The adult human body contains approximately 25 g of magnesium, 50 to 60% are located in the bone. Under normal conditions, in healthy individuals, 30 to 50% of ingested magnesium can be aborbé. In case of high dietary intake, kidney removes excess magnesium as the mechanism of renal reabsorption of magnesium operates at a rate close to saturation. Conversely, when the supply decreases, the tubular reabsorption dimine. Acute alcohol intake leads to a leakage of urine magnesium.
