Magnesium oxide is an inorganic form of magnesium with a high content of elemental magnesium per gram. It is often used because of its compact composition and long shelf life. A downside is that this form dissolves less readily in water, so it is absorbed relatively slowly.
Elemental magnesium refers to the amount of magnesium that is actually available per dosage, separate from the weight of the compound it is bound to.
| Composition per serving (1 tablet) | RI* | |
|---|---|---|
| Elemental magnesium (as magnesium oxide) | 250 mg | 66.67% |
