Magnesium - distribution and basic metabolism
Magnesium is extensively distributed in soil, water and plants. It is essential for ehzymatic reactions requiring adenosine triphosphate, and the recommended dietary allowance in man is 5 - 10 mg/kg/d. About 50% of magnesium in man is stored in bone, where it is regulated by parathyroid hormone'and 1,25(OH)2-D3. Most of the remaining magnesium pool is intracellular, plasma magnesium accounting for less than 0,5% of the total.
