Magnesium is an essential mineral that is used by every organ in the human body. Magnesium contributes to energy production and activates enzymes. Magnesium is found in many different foods, including green vegetables and whole grains. According to the University of Maryland Medical Center, it is rare to be truly deficient in magnesium, even if you do not get enough magnesium in your food in the United States. However, certain medical conditions can cause hypomagnesemia, or deficient magnesium levels.

Schedule an appointment with your physician if you believe you are low on magnesium. Some people have no symptoms and the only way to tell how low your magnesium levels are for sure is with a blood test. According to the National Institute of Health's MedlinePlus website, the normal range of magnesium in the blood is 1.7 to 2.2 milligrams per deciliter.
