Getting Your Magnesium Levels Back To NormalThere are plenty of ways to restore your Magnesium levels. Supplementation is obviously one route, but adding the right foods to your diet can be a powerful tool as well. In general terms, nuts and seeds contain the most Magnesium. Fish and vegetables are also good sources, while meat and dairy products tend to contain very little. See below a table showing the Magnesium content of a few sample foods. Men should be aiming for around 400mg per day, and women for around 320mg, depending on your age and health.
