Magnesium for Depression, Anxiety and General Health

Our body relies on magnesium (Mg) for multiple functions. It is a cofactor for more than 325 enzyme systems helping in various biochemical reactions – including blood pressure regulation, glucose control, protein synthesis, and mood stabilization. [Source: IMMH]

Over the years, many studies and researches have also linked magnesium to depression, anxiety, and ADHD. So, if you suffer from depression or other mental health disorders it might be due to magnesium deficiency.  [1]

Note: Magnesium deficiency may not be the only cause of your depression, but it plays a significant role in mood and stress management. 

Studies show that low brain Magnesium reduces serotonin (key mood-stabilizing and happiness hormone) levels. [Source: NCBI

Therefore, it is essential to maintain adequate magnesium levels to prevent mood irregularities like feeling low, anxious, or depressed. 

Magnesium Deficiency 

Despite its importance, many people suffer from subclinical magnesium deficiency (aka Hypomagnesemia). This common occurrence in clinical medicine often goes undetected because magnesium levels are rarely evaluated. [6]

Recent data indicates that 10%-30% of the population in developed countries has a subclinical magnesium deficiency. Moreover, a review of around 30 plus articles concluded that magnesium deficiency was a possible global public health concern for adults.

Since most people are unaware of magnesium deficiency, it is highly recommended to take magnesium supplements to maintain adequate Mg levels, thus, ensuring a healthy mind and body. [2]

Impact of Low Magnesium Levels on The Brain

In terms of magnesium deficiency and brain health connection, low magnesium levels have been linked to: [5]

  • Depression
  • Fatigue
  • Anxiety
  • Higher levels of stress
  • Insomnia or sleep disturbances
  • Headaches or muscle pain/tightness

Magnesium deficiency in the brain contributes to the symptoms mentioned above due to:

  • Overstimulation of Excitatory Neurotransmitters

Regulation of Excitatory neurotransmitters is directly involved in mental health and mood disorders. Excess excitatory transmitters can cause overexcitation of brain cells, leading to poor cognitive performance and unhealthy neurological conditions. [Source: IJPSR

Magnesium regulates these neurotransmitters but its deficiency enhances the activity of the stimulating transmitters and weakens calming receptors especially gamma-aminobutyric acid (GABA) receptors. Thus, resulting in a more restless and anxious state. 

  • Increased Production of Stress Hormones 

Low Magnesium results in a higher release of stress hormones such as cortisol which increases the risk of major depressive disorder. [Source: NCBI]

How Magnesium Deficiency Worsens Depression 

As stated earlier, magnesium plays a huge role in brain chemistry and impacts mood regulation through many enzymes, pathways, hormones, and neurotransmitters. So, those with magnesium deficiency may experience a multitude of physical and emotional symptoms. [4] Some can not only complicate and worsen depression but also cause it; these include: 

  • Premenstrual dysphoric disorder (PMDD) and Premenstrual syndrome (PMS)
  • Lower back pain 
  • Migraines and general headaches
  • Chest pain (particularly during an anxiety attack)
  • Muscle aches 
  • Joint pain
  • Digestive issues or Irritable Bowel Syndrome (IBS)
  • Fatigue and exhaustion
  • Issues with sleep
  • Low energy and motivation 
  • Poor concentration

The Evidence 

From A Meta-Analysis Study:

An article in The Journal of the American Board of Family Medicine found a deep correlation between low magnesium levels and depression by testing the National Health and Nutrition Examination Survey data set from 2004 to 2010. It indicated a 95% risk ratio (RR) of low magnesium intake and presence of depression. [3]

From: Rapid recovery from major depression using magnesium treatment by George A Eby et al. Med Hypotheses. 2006

Case histories are presented showing rapid recovery (less than 7 days) from major depression using 125-300 mg of magnesium (as glycinate and taurinate) with each meal and at bedtime

Another analysis of over 8,800 people found that people with low magnesium intake have a 22% higher risk of suffering from depression

From a Clinical Trial: 

The Journal of PLoS One published a randomized clinical trial in 2017 revealing that magnesium chloride intake significantly improved depressive symptoms. The study also concluded that the participants taking antidepressants experienced improved benefits with magnesium, proving it useful in conjunction with antidepressants.

Benefits of Taking Magnesium For Depression 

The beneficial effects of magnesium supplements on mood and depression are so well-known that it has attracted nicknames like the original chill pill,’ ‘nature’s valium,’ and the ‘mind mineral.’ 

Dr. Mark Hyman, a physician, wellness blogger, and New York Times best-selling author, defines magnesium as the most powerful relaxing mineral.’ 

Bassem El-Khodor, Ph.D., has conducted various studies linking magnesium to chronic health disorders. He states that magnesium is ‘the forgotten nutrient, and its supplementation can significantly reduce depression and its symptoms compared to placebo. [7]

Studies show that restoring normal levels of magnesium (magnesium repletion) creates positive changes in both mental and physical health; these include:

  • Better mood and cognition
  • Healthy eating behavior
  • Healthy stress responses
  • Lower risk of depression 
  • Improved quality of sleep
  • Better efficacy of other modalities (such as depression medication)

What Can You Do to Improve Your Magnesium Levels?

If you are experiencing mood irregularities or already suffering from depression, add enough magnesium to your diet and eat magnesium-rich foods or supplement with magnesium glycinate

Foods high in magnesium include:

  • Avocado
  • Leafy greens
  • Dark chocolate
  • Whole grains
  • Legumes
  • Nuts
  • Seeds

It would also be best if you got your magnesium levels checked. If you have low magnesium, you can take magnesium supplements. According to NHS UK, a healthy daily magnesium dose for men (19 to 64 years) is 300 mg a day and 270mg a day for women (19 to 64 years). 

Remember: Always consult your psychologist, nutritionist, naturopath, or GP before making any changes to your regimen or diet. Also, avoid taking any supplements without your doctor’s recommendation if you are already under treatment for depression or any mental health disorder.
