Every organ in the body, especially the heart, muscles, and kidneys, needs the mineral magnesium. It also contributes to the makeup of teeth and bones. Magnesium is needed for many functions in the body. This includes the physical and chemical processes in the body that convert or use energy (metabolism).
Magnesium glycinate -- Magnesium glycinate (magnesium bound with glycine, a non-essential amino acid) is one of the most bioavailable and absorbable forms of magnesium, and also the least likely to induce diarrhea. It is the safest option for correcting a long-term deficiency.
