There is no doubt that magnesium is vital to our health. It stabilises and assists the operation of hundreds of enzymes that catalyse key chemical processes in the body. It also provides stability to fundamental molecules like DNA and ATP (adenosine triphosphate), binds to various receptors and can move in and out of cells. This has earned it roles in a vast array of crucial processes including energy production in cells, nerve signalling, muscle contractions and heartbeat regulation.
