Magnesium is a mineral your body needs for hundreds of processes, including muscle and nerve function, bone building, and blood sugar regulation. You get it most reliably through food such as nuts, whole grains, and green vegetables. If you choose to supplement, organic forms like magnesium citrate or glycinate are better absorbed than magnesium oxide; sprays and salt baths lack scientific support.
