Uses of This Medicine
Magnesium is used as a dietary supplement for individuals who are deficient in magnesium. Although a balanced diet usually supplies all the magnesium a person needs, magnesium supplements may be needed by patients who have lost magnesium because of illness or treatment with certain medicines.
Injectable magnesium is given only by or under the supervision of a health care professional. Some oral magnesium preparations are available only with a prescription. Others are available without a prescription.
Importance of Diet
For good health, it is important that you eat a balanced and varied diet. Follow carefully any diet program your health care professional may recommend. For your specific dietary vitamin and/or mineral needs, ask your health care professional for a list of appropriate foods. If you think that you are not getting enough vitamins and/or minerals in your diet, you may choose to take a dietary supplement.
The best dietary sources of magnesium include green leafy vegetables, nuts, peas, beans, and cereal grains in which the germ or outer layers have not been removed. Hard water has been found to contain more magnesium than soft water. A diet high in fat may cause less magnesium to be absorbed. Cooking may decrease the magnesium content of food.
The daily amount of magnesium needed is defined in several different ways.
For U.S.—Recommended Dietary Allowances (RDAs) are the amount of vitamins and minerals needed to provide for adequate nutrition in most healthy persons. RDAs for a given nutrient may vary depending on a person’s age, sex, and physical condition (e.g., pregnancy). Daily Values (DVs) are used on food and dietary supplement labels to indicate the percent of the recommended daily amount of each nutrient that a serving provides. DV replaces the previous designation of United States Recommended Daily Allowances (USRDAs).
For Canada—Recommended Nutrient Intakes (RNIs) are used to determine the amounts of vitamins, minerals, and protein needed to provide adequate nutrition and lessen the risk of chronic disease.
Normal daily recommended intakes in milligrams (mg) for magnesium are generally defined as follows:Persons U.S.(mg) Canada(mg) Infants birth to 3 years of age 40 to 80 20–50 Children 4 to 6 years of age 120 65 Children 7 to 10 years of age 170 100–135 Adolescent and adult males 270–400 130–250 Adolescent and adult females 280–300 135–210 Pregnant females 320 195–245 Breast-feeding females 340–355 245–265
