Magnesium plays an essential role in a wide range of fundamental biological reactions in the body. It is involved in over 300 essential enzymatic reactions and is necessary for every major biological process. It is especially important for those enzymes that use nucleotides as cofactors or substrates and plays a role in many processes that are of central importance in the biochemistry of each cell, particularly in energy metabolism. It is also required for many other important biological functions such as:
• nerve conduction
• regulation of vascular tone
• muscle activity
• amino acid and protein synthesis
• DNA synthesis and degradation
• immune function.
INTERACTION WITH OTHER NUTRIENTS
Magnesium is extremely important for the metabolism of calcium, potassium, phosphorus, zinc, copper, iron, sodium, lead, cadmium and the intracellular homeostasis and activation of thiamine. It acts as a calcium antagonist and interacts with nutrients such as potassium, phosphorus, vitamin B6 and boron.
Magnesium: Other Actions
In its macro form, oral Mg salts have a laxative and antacid activity and are practically insoluble in water.
