Magnesium for anxiety and depression

Anxious? Depressed? Irritable? While there are lots of reasons for mood changes one may be that you are low in magnesium. In fact there is evidence to suggest that magnesium could be a safe and effective treatment for depression.

Magnesium is an essential dietary nutrient found in green leafy vegetables, whole grains and nuts and seeds though intakes have been declining due to modern farming and food processing and most people are not getting enough in their diet (1). Furthermore, physical and mental stress can increase magnesium loss (2). 

Experimental studies have linked magnesium deficiency to anxiety and depression (3). And people with low dietary magnesium are much more likely to be depressed (4).

Studies show striking benefits:

A clinical study contrasting the effects of magnesium (450 mg daily) against a popular anti-depressant drug found that magnesium was highly effective in treating depression and as effective as medication (5).

In a series of case studies it was also shown that magnesium treatment (125–300 mg of magnesium with each meal and at bedtime) resulted in rapid recovery from major depression (in less than 7 days) including symptoms of headache, suicidal thoughts, anxiety, irritability, insomnia, post pregnancy depression, cocaine, alcohol and tobacco abuse and short-term memory loss (6)

And as far back as the 1920s magnesium was used to successfully (a 90% success rate) treat agitated depression, increasing sleep and relaxation (7).

The collective evidence and clinical success with magnesium has led some doctors to suggest that “due to its safety and efficacy, physicians should prescribe magnesium for treatment resistant depression without further delay, even though much more clinical research is needed to confirm and extend this important line of research (8).”

How to increase your magnesium intake:

  • Eat plenty of magnesium rich foods: whole oats, dark chocolate, brown rice, almonds, hazelnuts, peanuts, lima beans, spinach, swiss chard, okra, and bananas.

  • Take a high quality magnesium dietary supplement providing about 300 mg of magnesium once to twice daily for 3-4 months.
