# 500 mg Magnesium malate: how much elemental magnesium?

> If 500 mg is the weight of the Magnesium malate compound, it holds about 75 mg of elemental magnesium, because Magnesium malate is about 15% magnesium by weight. Many labels instead list “Magnesium 500 mg (as Magnesium malate)”, and that number is already elemental. Check which one your Supplement Facts panel shows.
