How many milligrams is 5000 iu of magnesium?

The conversion of international units (IU) to milligrams (mg) for magnesium depends on the specific compound being measured, as different magnesium compounds have different potencies. However, magnesium is not commonly measured in IU; it is usually measured directly in milligrams. For example, 5000 IU is not a standard measurement for magnesium, so it's best to refer to the specific product's labeling for accurate conversion.
