There may be a decrease in hyperactivity of children when magnesium is at a proper level. It is also been suggested that low levels of magnesium may also play a part in the chronic fatigue patient, specifically in relation to proper functioning of muscles. Nearly one third of Americans over age 50 are deficient in magnesium. Symptoms of deficiency may include fatigue, muscle weakness, sleepiness, feelings of excitability, and irregular heartbeat. Our richest source of magnesium comes from dark green leafy vegetables.
Nuts are a good source, especially brazil nuts, pecans, and cashews.
Beans, whole grains such as brown rice and millet, soy products, fish, and dried apricots and avocados are also good sources. Magnesium can be taken as supplements in tablet or capsule form. Consult your health care professional for proper dosage. An overdoage or toxic level of magnesium from food sources would be virtually impossible. However, when taking supplements you must follow dosages set by your health care professional.
