The safest way to ingest magnesium is through a good diet, but supplements are also available over-the-counter, according to WebMD. Magnesium deficiency is common in the United States and mostly affects the elderly and African-Americans.
Getting enough magnesium through the diet is recommended, and knowing what foods are high in magnesium is to know what foods are high in fiber, explains WebMD. The best dietary forms of magnesium include legumes, broccoli, whole grains and almonds. People also get magnesium by eating dairy products and chocolate, or by drinking coffee and hard water. If a person does not get enough magnesium in the diet, a doctor may recommend an over-the-counter magnesium supplement.
Over-the-counter magnesium supplements may also be used to treat a variety of conditions, such as constipation and high blood pressure during pregnancy, claims WebMD. Magnesium supplements are also often taken for a sour stomach, heartburn or irregular heartbeat. Those who take magnesium should understand that these supplements might interact with certain antibiotics, blood pressure medications and water pills. If a person is taking any of these medications, it is recommended that the individual consult with a doctor. Pregnant or breastfeeding women, those with bleeding disorders, kidney problems or heart block should also use caution with magnesium.
