Question:


Answers:
I think there are many, but for me this is the main:
Magnesium ion is essential to the basic nucleic acid chemistry of life, and thus is essential to all cells of all known living organisms. Plants have an additional use for magnesium in that chlorophylls are magnesium-centered porphyrins. Many enzymes require the presence of magnesium ions for their catalytic action, especially enzymes utilizing ATP, or those which use other nucleotides to synthesize DNA and RNA.
Magnesium
General Description
Magnesium is a major mineral needed by every cell in the human body. About half of the body's magnesium is found in the bones, with the other half distributed to organs and tissues throughout the body. Only 1 percent of the body's magnesium is found in the blood. Magnesium is needed for more than 300 biochemical reactions in the body. It is essential for bone development and maintenance, muscle and nerve function, and cardiovascular health. It also plays important roles in protein synthesis and energy metabolism. Magnesium in supplements (such as magnesium chloride, carbonate, oxide, succinate, orotate, gluconate, aspartate, glycinate, citrate, malate, and fumarate) is bound to other molecules to make it stable.
Food sources
Magnesium is found in a wide variety of foods, usually in small amounts. Good sources of magnesium include whole grains, nuts, beans, tofu, and dark green vegetables. Meat, fish, and dairy products also provide significant amounts.
