Could it be as simple as not having enough magnesium in your body?

Magnesium is much more than a simple electrolyte

– it is involved in more than 300 biological functions and is essential for heart health.
Any prescribed doses of magnesium are likely to be woefully inadequate because of a fear of possible side effects.

The symptoms of magnesium deficiency include:


Behavioral disturbances
Irritability and anxiety
Impaired memory and cognitive function
Anorexia or loss of appetite
Nausea and vomiting


Weakness (SHERMER’S NECK?)
Muscle spasms (tetany)
Muscle cramps 
Hyperactive reflexes
Impaired muscle coordination (ataxia)
Involuntary eye movements and vertigo
Difficulty swallowing


Increased intracellular calcium
Calcium deficiency
Potassium deficiency


Irregular or rapid heartbeat
Coronary spasms

Among children:

Growth retardation or “failure to thrive”

Note that cramping is associated with magnesium deficiency
but not hypermagnesemia (too much magnesium).

Blood Tests

Only 1% of magnesium in the body is actually found in blood, and only .3% is found in blood serum, so clinical blood serum testing is not useful.

Risk Factors

Possible neurological signs of magnesium deficiency:

  • Anxiety
