Magnesium is important in more than 300 chemical reactions that keep the body working properly. People get magnesium from their diet, but sometimes magnesium supplements are needed if magnesium levels are too low. Dietary intake of magnesium may be low particularly among women, African Americans and the elderly.

Magnesium is also used as a laxative for constipation and for preparation of the bowel for surgical or diagnostic procedures. It is also used as an antacid for acid indigestion.

Some people use magnesium for diseases of the heart and blood vessels including chest pain, irregular heartbeat, high blood pressure, high levels of “bad” cholesterol called low-density lipoprotein (LDL) cholesterol, low levels of “good” cholesterol called high-density lipoprotein (HDL) cholesterol, heart valve disease (mitral valve prolapse), and heart attack.

Magnesium is also used for treating attention deficit-hyperactivity disorder (ADHD), anxiety, chronic fatigue syndrome (CFS), Lyme disease, fibromyalgia, leg cramps during pregnancy, diabetes, kidney stones, migraine headaches, weak bones (osteoporosis), premenstrual syndrome (PMS), altitude sickness, urinary incontinence, restless leg syndrome, asthma, hayfever, multiple sclerosis, and for preventing hearing loss.

Athletes sometimes use magnesium to increase energy and endurance.
