Description
Magnesium, Mg, is the second most abundent INTRAcellular ion within the mammalian body:
- Potassium
- Magnesium
- Phosphate
It is a vital co-factor for enzymes, particularly those involved with ATP-production and Nucleic Acid Synthesis.
The majority is stored in bone, with just 1% of the total body Mg being free in it's ionised form within the blood.
There is no hormonal control/regulation of Magnesium, so within the body there is a balance between inflow from the diet and outflow via Urine, Saliva and Milk. Excess outflow not easily remedied, due to the lack of homeostatic mechanisms for this ion.
