Bible DictionaryHepatitis Central (TM) Liver Disease Medical Glossary
Essential mineral. Chief function of magnesium is to activate certain enzymes, especially those related to carbohydrate metabolism. Also to maintain the electrical potential across nerve and muscle membranes. Essential for proper heartbeat and nerve transmission. Magnesium controls many cellular functions. Involved in protein formation, DNA production and function and in the storage and release of energy in ATP. Magnesium is closely related to calcium and phosphorus in body function. The average adult body contains approximately one ounce of magnesium. It is the fifth mineral in abundance within the body--behind calcium, phosphorus, potassium and sodium. Although about 70 % of the body's magnesium is contained in the teeth and bones, its most important functions are carried out by the remainder which is present in the cells of the soft tissues and in the fluid surrounding those cells
Bible DictionaryDictionary of Medicine
A mineral involved in many processes in the body including nerve signaling, the building of healthy bones, and normal muscle contraction. Magnesium is contained in all unprocessed foods. High concentrations of magnesium are found in nuts, unmilled grains and legumes such as peas and beans. Magnesium deficiency can occur due to inadequate intake or impaired intestinal absorption of magnesium. It is often associated with low calcium (hypocalcemia) and low potassium (hypokalemia). Deficiency of magnesium causes increased irritability of the nervous system with tetany (spasms of the hands and feet, muscular twitching and cramps, spasm of the larynx, etc.). According to the National Academy of Sciences, the Recommended Dietary Allowances of magnesium are 420 milligrams per day for men and 320 milligrams per day for women. The upper limit of magnesium as supplements is 350 milligrams daily, in addition to the magnesium from food and water. Persons with impaired kidney function should be especially careful about their magnesium intake because they can accumulate magnesium, a dangerous situation.
