Magnesium and Stress – Can Deficiencies of This Mineral Increase Tension and Anxiety?

The modern lifestyle – fast pace, information overload, sleep deprivation, and processed food – not only promotes chronic stress but also... magnesium deficiency. While these may seem like two unrelated issues, science increasingly shows they are closely linked. Could it be that a lack of magnesium affects our mental wellbeing more than we ever thought?

Magnesium and the Nervous System – How It Works

Magnesium is one of the most essential minerals in the human body. It’s involved in over 300 enzymatic processes, including those crucial for proper nervous system function. It supports nerve conduction, is involved in the production of neurotransmitters, and influences the function of GABA (gamma-aminobutyric acid) receptors – the brain’s main calming neurotransmitter.

Importantly, magnesium acts as a natural blocker of excessive neuronal activity, protecting the nervous system from overload. This is why a proper level of magnesium can promote a sense of calm, emotional balance, and resilience to stress.

Stress and Magnesium Loss – A Vicious Cycle

Stress activates the HPA axis (hypothalamus–pituitary–adrenal), leading to the release of cortisol and adrenaline. In stressful situations, the body consumes more magnesium and simultaneously excretes it more quickly through urine. This means people living under chronic stress are particularly at risk of magnesium deficiency.

Even worse – a magnesium deficiency intensifies the stress response, increases nervous system excitability, and impairs emotional regulation. A vicious cycle forms: stress depletes magnesium, and low magnesium increases stress sensitivity and worsens mental health.

Signs of Magnesium Deficiency That May Reflect Stress Overload

Anxiety, irritability, low mood, trouble falling asleep, headaches, muscle tension, and even heart palpitations – these are common symptoms of magnesium deficiency, and they frequently accompany chronic stress. Unfortunately, many people don’t associate them with a potential magnesium shortfall, and lab tests (e.g., blood magnesium levels) don’t always reveal the true status of tissue magnesium levels.

This is why more and more health professionals recommend magnesium supplementation as part of a mental health support strategy – especially for those exposed to constant pressure, working under high tension, or struggling with sleep and recovery.

Magnesium and Anxiety – What Does the Research Say?

A 2017 meta-analysis published in Nutrients reviewed 18 studies on the impact of magnesium supplementation on anxiety symptoms. The conclusion? In individuals with elevated anxiety levels, magnesium supplementation may offer moderate but significant mental health benefits.

A 2020 systematic review (Rajizadeh et al.) also found that magnesium may have beneficial effects in both anxiety and depression, particularly when used as an adjunct to conventional psychological or pharmacological therapy.

Magnesium also plays a role in regulating the HPA axis – helping to “turn down” the stress response, which may explain its calming and restorative effects.

Which Form of Magnesium Is Most Effective?

Not all forms of magnesium are equally bioavailable. Research shows that citrate, taurate, glycinate, and lactate forms are better absorbed than, for example, magnesium oxide.

For reducing stress and supporting neurological health, special attention should be given to:

• Magnesium glycinate – gentle on the stomach, bonded with glycine, an amino acid with calming effects.

• Magnesium taurate – combined with taurine, supports both the nervous and cardiovascular systems.

• Magnesium citrate – highly absorbable and commonly used in a wide range of supplements.

Magnesium-Rich Foods and Stress – What to Eat to Support the Nervous System?

Natural sources of magnesium include:

• pumpkin and sunflower seeds,

• nuts (almonds, cashews),

• cocoa and dark chocolate,

• whole grains,

• legumes,

• spinach and kale,

• bananas and avocados.

Unfortunately, the modern diet – high in simple sugars and processed foods – often fails to provide sufficient magnesium. Additionally, stress, coffee, alcohol, and certain medications can increase its loss from the body.

That’s why, for individuals dealing with stress or mood disorders, magnesium supplementation may offer real support – as part of a broader approach to recovery and mental balance.
