Why is Magnesium essential?

Magnesium is required for energy production. It contributes to the structural development of bone and is required for the synthesis of DNA and RNA. Magnesium also plays a role in the active transport of calcium and potassium ions across cell membranes, a process that is important to nerve impulse conduction, muscle contraction, and normal heart rhythm.
