Magnesium deficiency creates the symptoms of accelerated aging such as irregular heart beat, insulin resistance, high blood pressure, osteoporosis, increased risk of heart attack and a tendency to diabetes. Researchers estimate that 75% of all Americans are, to some extent, deficient in magnesium. Magnesium not only protects cells against aging, it works in tandem with calcium to strengthen bones and protect against osteoporosis. Although many people now supplement with calcium (along with Vitamin D), a lot of people remain unaware that magnesium works in tandem with calcium and is equally important for strong bones. It is recommended that you supplement with half as much magnesium as calcium. Refined sugar and dairy products interfere with the absorption of magnesium and therefore should be avoided as much as possible. Long term magnesium deficiency also leads to lower levels of Vitamin E are used for fighting the free radicals encouraged by the magnesium deficiency. You can supplement with magnesium chloride, magnesium aspartate, magnesium gluconate and magnesium lactate. A daily supplement of 200 to 300 mcg is recommended if you don�t eat enough foods rich in magnesium. Magnesium is found in whole grains, nuts, seeds, legumes.
