Thus, if Mg is deficient, the shortage of chlorophyll results in poor and stunted plant growth. Magnesium is well known for its diverse actions within the human body.

Functions and Importance of Mg Magnesium is an essential constituent of chlorophyll; it is the center of the chlorophyll molecule. Irrespective of the effect magnesium has on blood pressure, higher intake of the mineral is associated with lower risk of heart disease and stroke (11, 12). Serum levels are often slightly elevated in patients on chronic hemodialysis and older reports suggests that total body stores may also be increased, based on bone biopsies in patients treated with higher dialysate magnesium levels than are currently in use today.

Magnesium deficiency and hypomagnesemia are quite common, difficult to diagnose (due to underestimation and rare level control) and accompany many diseases of the cardiovascular system and beyond. A specific mechanism of defense to diseases enhanced by Mg includes increased resistance of tissues to degradation by pectolytic enzymes of bacterial soft rotting pathogens.
