Magnesium plays a role in over 300 enzymatic reactions within the body, including the metabolism of food, synthesis of fatty acids and proteins, and the transmission of nerve impulses.Magnesium is the eighth most abundant element on the earth's crust, and is found in every organ in the human body. The physician Joseph Black first recognized magnesium as an element in 1755, but even before Black's time, physicians were recommending the magnesium carbonate "magnesia alba" for people with an upset stomach. Today, researchers know magnesium plays a part in more than 300 reactions in the body. Magnesium is necessary to synthesize proteins, DNA and RNA. It plays a role in our metabolism, and cells use magnesium to transport calcium and potassium ions across the cell walls.
