"Magnesium Facts"

Magnesium is a mineral important for muscle contractions, a healthy nervous system, immune system and strong bones. It is involved in hundreds of enzyme reactions in the body.Excessive intake of magnesium from food does not happen; however, if intake of magnesium supplements is high over time, then muscle weakness, diarrhea, abdominal cramping, risk of kidney failure, and irregular heartbeat may occur.What happens when Magnesium intake is too low? Deficiencies are rare in healthy adults, but may be seen in individuals with gastro-intestinal malabsorptive conditions, burns, surgery, renal disease, hyperthyroidism, and alcoholism. Symptoms can include fatigue, irritability, decreased appetite, confusion, rapid heartbeat, and numbness. Magnesium occurs abundantly in foods. Good sources include seeds, nuts, legumes, dark green vegetables, soy products, and whole grains. Magnesium is one of the body's major electrolytes, essential for metabolism, and an aid to the growth of bone as well as nerve and muscle health. Researchers now believe magnesium is responsible for the health of the heart, blood pressure, circulation, and overall relaxation including muscle relaxation. Professional athletes or anyone who engages in heavy physical labor must keep magnesium levels up, as the mineral facilitates oxygen delivery to working muscle tissue.
