Magnesium plays an essential role in many of the functions of energy production, oxygen uptake, central nervous system function, electrolyte balance, glucose metabolism and muscle activity, most importantly the heart. At the molecular level, a healthy magnesium concentration is a natural antioxidant protecting molecules from free-radical damage, which according to certain studies makes it a cancer fighting property. Some say it’s one of the most important minerals in cancer depression. Some signs of magnesium deficiency are nausea, anxiety, muscle cramps, tremors, fatigue, weakness, dizziness, difficulty swallowing and poor memory. According to the American Chiropractic Society, 68 to 80 percent of Americans are deficient in Magnesium, one of the most essential minerals the human body needs. The main reason is depletion of minerals in the soil. Fruits and vegetables that were once rich with magnesium have much lower amounts because of today’s soil issues. This has caused many people to start moving towards magnesium supplements. The best forms are Magnesium citrate, taurate, malate, glycinate, chloride and carbonate. The worst forms are oxide, sulfate, glutamate and aspartate.
