Magnesium oxide is an inorganic salt of magnesium formed with ions of magnesium and oxygen. Magnesium oxide and other inorganic salts of magnesium like magnesium carbonate are high in elemental magnesium, which is the total amount of magnesium in a supplement.

Magnesium is an important mineral in the human body involved in over 300 essential metabolic reactions including energy production, blood pressure regulation, nerve signal transmission, and muscle contraction.

Magnesium deficiency can have health consequences such as type 2 diabetes, heart disease, osteoporosis and migraine. Magnesium plays an important role in your body’s stress response. In fact, studies have shown that people who experience frequent stress tend to have lower magnesium stores. Some studies have shown that supplementing with magnesium may help reduce levels of stress and anxiety. Significant research has shown also that people with migraines often have lower levels of magnesium than those without them.
