USES:Magnesium is a mineral vital for energy production and needed for muscle relaxation as well as calcium metabolism.
Magnesium is also necessary for the secretion and production of insulin, the hormone that helps regulate blood sugar levels.
Excessive amounts of fibre in the diet may decrease magnesium absorption and too much protein can increase magnesium elimination in the urine.
The contraceptive pill may interfere with magnesium absorption and metabolism, high stress levels, pregnancy and lactation and alcohol and caffeine may deplete magnesium levels.
Weakness, fatigue and anxiety as well as muscle weakness and cramps, eye twitches, high blood pressure, insomnia, constipation and hyperactivity and failure to thrive in children are all potential symptoms of magnesium deficiency.
Food sources of magnesium are wholegrains, avocados, spinach, broccoli, green beans, tomato juice, pinto beans, sunflower seeds, tofu, cashews, Brazil nuts, almonds, quinoa, black-eyed peas, artichoke and halibut.
