The Calming Mineral? Exploring the Evidence of Magnesium Supplementation for Anxiety

As we navigate the complex world of mental health, magnesium supplementation has emerged as a potential natural remedy for a range of conditions including insomnia, depression, and, notably, anxiety. This post delves into the research backing these claims, specifically focusing on anxiety. 

 

Magnesium’s purported role in managing anxiety 

 

Magnesium, a vital mineral found abundantly in the human body, plays a crucial role in numerous biochemical reactions. It's essential for nerve function, muscle relaxation, and maintaining a healthy immune system. The purported benefits for anxiety stem from its effects on cortisol.

Cortisol, often referred to as the "stress hormone," plays a pivotal role in the body's response to stress. Produced by the adrenal glands, it regulates a variety of vital processes, including metabolism, immune response, and helping the body manage stress by increasing energy levels, blood sugar, and brain's use of glucose, while also curbing non-essential functions in a fight or flight situation. 

The amount of magnesium in your body has been shown to be highly correlated with cortisol levels. Low magnesium is associated with higher cortisol levels, and vice versa! It is important to remember that cortisol levels do not exactly correlate with symptoms of anxiety, so more research than this is needed to prove an effect. 

Beyond cortisol regulation, magnesium's influence extends to the brain's chemical messengers. There is some evidence that magnesium may inhibit excitatory neurotransmitter glutamate and stimulate the release of the inhibitory neurotransmitter GABA. Think of this like the body’s anxiety “on-off” switch.  

  

Current Evidence from Research 

 

We’ve looked at what magnesium can do in theory, but what about studies looking specifically at how supplementing with it affects anxiety? One study did just that: 

A systematic review published in the journal Nutrients investigated 18 different studies focused on magnesium supplementation. Eight of these studies specifically recruited participants with mild subjective anxiety. Unfortunately, only 3 out of 8 of those studies found significant changes to anxiety with magnesium supplementation compared to placebo.  

To date, this appears to be the largest study reviewing magnesium’s effects on anxiety. A systematic review like this is considered robust evidence because it comprehensively analyzes data from multiple studies, providing a more balanced perspective than individual studies. 

This does not exclude a potential therapeutic effect of magnesium, but the current evidence is lacking. 

 

Trying it for yourself 

 

If you’re on the fence, you might want to try it yourself. While the research is somewhat lacking now, there is an abundance of anecdotal evidence from patients and physicians alike.

Magnesium can be found in foods like leafy greens, nuts, seeds, and whole grains. However, for those considering supplements, magnesium comes in various forms, such as magnesium citrate, oxide, and glycinate.

Just remember that there is such a thing as too much Magnesium, so be sure to consult with a healthcare professional before supplementing. 

 

Ask your healthcare provider
