Many Americans do not understand the importance of magnesium in the same way they understand calcium or iron, for instance. Nonetheless, adequate magnesium levels are crucial for brain, cardiac and muscle function and it is needed, along with silica and Vitamins D and K to promote bone health. Magnesium deficiency is more common than many people suspect, and below are 5 warning signs that could indicate a deficiency in this important mineral.

1. Ringing in the Ears or Hearing Loss
Tinnitus, or a constant, high-pitched ringing in the ears is common symtom of magnesium deficiency, as is hearing loss. There are have been a number of studies done on the relationship between ear health and sufficient magnesium levels. In one Chinese study, it was found that magnesium in sufficient quantities will prevent the formation of the free radicals that can lead to hearing loss. In a study at the Mayo Clinic, it was found that treating patients who had experienced hearing loss with magnesium supplementation often helped restore that loss within three months.

2. Muscle Cramps or Tremors
Magnesium is crucial to optimim muscle function. Without it, the body would be in a state of convulsion, because it is this mineral that allows the muscles to relax. That is why, for instance, a magnesium oxide drip is used to ease women in labor and why magnesium is found in so many sleep-inducing supplements. A lack of sufficient magnesium, therefore, can lead to facial tics, muscle cramping and twitching or cramping of the feet while trying to sleep.
