Pay attention: 12 signs you need more magnesium.

Low levels of magnesium in the brain can affect neurological functions that result in all sorts of problems. Studies have shown that some phobias — such as agoraphobia — have developed as a result of low magnesium levels, Dr. Hoffman says. Magnesium has long been used as an effective home remedy for these symptoms, says Psychology Today in an article titled “Magnesium and the Brain: The Original Chill Pill.”
If you suspect that you may be suffering from a magnesium deficiency, it is advisable to confirm your suspicion by consulting your doctor.
