Magnesium is one of the body’s most important minerals. It is required as a co-factor in hundreds of enzymatic processes within cells.16 It helps maintain normal muscle and nerve function, keeps heart rhythm steady, promotes a healthy cardiovascular function, supports a healthy immune system, and keeps bones strong. Magnesium also helps maintain blood sugar and blood pressure levels already within normal range, and it is known to be involved in energy metabolism and protein synthesis.17,18

Magnesium is a major factor in relaxing the smooth muscles within the blood vessels, thereby reducing peripheral vascular resistance and promoting a healthy cardiovascular system.19-21 Magnesium also affects circulating levels of norepinephrine and the synthesis of serotonin and nitric oxide.16,22-24

Magnesium positively influences the bone mineral matrix and its ability to metabolize minerals needed for repair and rebuilding.25,26 The scientific literature documents the need for a wide range of minerals, including calcium and magnesium, that are vital to maintaining strong, healthy bones.

A review of assimilation studies suggests that the citrate salt of magnesium is the best absorbed into the bloodstream.69,70 Magnesium citrate, however, is comprised of only 16% magnesium, and the recommended intake of elemental magnesium is 300 mg to 800 mg a day.71,72
