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.
