Signs that you have a magnesium deficiency

Some of the most frequent complaints I hear from my patients, especially those older than 50, involves muscle cramps and spasms, notably those leg zingers that make them jump out of bed in the middle of the night; trouble sleeping and daytime stiffness or pain in their muscles.

Most of my patients laugh these symptoms off as just “getting old”, but they’re surprised when I tell them these are more likely symptoms of a magnesium deficiency, which can easily be corrected.  Read on and see if you have any of the common symptoms of low magnesium and what I recommend.    

Symptoms of Low Magnesium

Magnesium is a “macro mineral”, which means it is one of the 6 most important minerals for which your body requires large amounts.

However, magnesium deficiency is fairly common in people over the age of 50 and can stem from a variety of things from dietary imbalances to certain health conditions.  In fact, less than 30% of Americans get the RDA of magnesium, which is the absolute minimum recommendation for magnesium a day!

Magnesium deficiency is most common in menopausal women who usually start taking calcium supplements for bone health and may be on oestrogen replacement therapy.  If you don’t take a magnesium balanced calcium supplement, you can become deficient in magnesium.  Low carb dieting can also lead to magnesium decreases.

However, men also get magnesium deficiencies – especially if they drink a lot of coffee, tea or carbonated sodas, or eat a few sugary snacks during the day. Excess refined dietary sugar causes you to lose a lot of magnesium through urination.

Also, if you are under stress frequently, you can become deficient in magnesium due to your body’s increased production of cortisol and adrenaline.  Both of these chemicals can deplete your magnesium stores.

Blood tests only show what magnesium is circulating in the blood at the time of the test.  Symptoms are a better gauge to determining if you have a deficiency.


The classic physical signs of low magnesium are:


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


Muscle spasms (t tetanus
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”


In addition to symptoms of overt hypomagnecemia (clinically low serum magnesium), the following conditions represent possible indicators of chronic latent magnesium deficiency:

  • Depression
  • Chronic fatigue syndrome
  • ADHD
  • Epilepsy
  • Parkinson’s disease
  • Sleep problems
  • Migraine
  • Cluster headaches
  • Osteoporosis
  • Premenstrual syndrome
  • Chest pain (angina)
  • Cardiac arrhythmias
  • Coronary artery disease and atherosclerosis
  • Hypertension
  • Type II diabetes
  • Asthma

As I explain to my patients, magnesium is a critical mineral that your body needs to perform all its major functions – especially your heart, muscles and kidneys.  In fact, magnesium is one of the first treatments given in emergency departments in heart attack patients.

Optimal magnesium levels can also prevent stroke and obesity.
