Magnesium is a mineral that plays an important role in maintaining healthy bones. It contributes to increased bone density and helps prevent the onset of osteoporosis. Most people do not get enough magnesium in their diets, especially if they eat large amounts of processed foods in which much of the magnesium is removed.
Since magnesium works closely with calcium, it is important to have an appropriate ratio of both minerals in order for them to be effective. A good rule of thumb is a 2:1 calcium-to-magnesium ratio. For example, if you take 1000mg of calcium, you should also take 500mg of magnesium.
