Sources of Magnesium

Magnesium is widely distributed in plant and animal foods and in beverages. Green leafy vegetables such as spinach, legumes, nuts, seeds and whole grains are good sources. In general, foods containing dietary fibre provide magnesium. Some types of food processing, such as refining grains in ways that remove the nutrient-rich germ and bran lowers magnesium content substantially. Approximately 30-40% of the dietary magnesium consumed is typically absorbed by the body.
