Magnesium deficiency is said to be one of the most common nutrient deficiencies. It is involved in regulation of impulse conduction in the nervous system as well as in the musculoskeletal system, where it functions as an inhibitory ion and muscle relaxant. Magnesium also serves as a cofactor for many biochemical reactions related to energy production in the body as well; for example, glycolysis and the Krebs cycle, both of which are important in the generation of a molecule called adenosine triphosphate (ATP). ATP is the chemical form of energy inside each cell. In the digestive system, magnesium also has a gentle laxative effect.

Supplementation with magnesium has been found to benefit conditions affected by muscle spasm, such as migraine, which is caused by spasm of the smooth muscle of blood vessels travelling to the head.[1] Menstrual cramps, which are caused in part by contraction of the uterine muscle, are also improved with magnesium supplementation.[2] Other conditions such as restless leg syndrome or calf cramping like charley horse may also benefit.[3] Because magnesium is also an inhibitory factor in the nervous system, supplementation with magnesium may also help promote relaxation and sleep.[4]
