Can magnesium really help with anxiety and depression?

Let's start with a brief overview of magnesium – what exactly is it and why do we need it? Well, magnesium is a mineral. It is essential for us humans. The reason for this is that magnesium plays a role in many functions and processes in your body. The mineral ensures strong bones and teeth, regulates the stability, permeability and division of your cells, provides energy, helps control your hormone balance, protects your heart, supports your muscles in regeneration and is involved in the production of the happiness hormone serotonin, which puts you in a good mood. A true all-rounder – but that's not all.

If you are plagued by fears and worries and are under stress, your body tries to compensate for this. The result: it produces more stress hormones, which put you on alert. Your heart beats faster, your blood pressure rises, your muscles tense up. And magnesium consumption also increases. Our ancestors used these bodily mechanisms to act quickly or flee from enemies – and thus survive. Today, however, we often lack a meaningful use for this evolutionarily developed excess of stress hormones – they remain largely unused in your body. To break them down again, you need magnesium.

In summary, this means that In stressful situations, your body excretes more magnesium – and therefore needs more to compensate. If this is only a short-term period of stress, your body can usually cope well. However, if you are under constant pressure, there is a risk that you will develop a magnesium deficiency – and this makes you more susceptible to anxiety and depression.

Symptoms and risk factors of magnesium deficiency

A magnesium deficiency can manifest itself in many different ways – both physically and psychologically. Important symptoms include:

• Muscle cramps and twitching
• Diabetes
• High blood pressure
• Digestive problems
• Menstrual cramps and PMS
• Osteoporosis
• Brittle fingernails
• Increased sensitivity to stress
• Depressive moods
• Headaches & migraines
• Sleep disorders
• Inner restlessness
• Difficulty concentrating
• Tingling or numbness in the hands and feet

The nervous and mental warning signs in particular clearly demonstrate the significant impact that magnesium deficiency can have on our psyche. Conversely, this also means that if you manage your magnesium deficiency effectively, there is a good chance that you will experience fewer of these symptoms. Let us take a closer look at this.

There is now a great deal of knowledge circulating on the subject of magnesium and anxiety. Many people are therefore rightly asking themselves: does magnesium help with depression and anxiety? Studies reveal the following:

# Magnesium regulates the stress hormone cortisol

In particularly stressful times, your body produces more of the stress hormone cortisol to help you cope with the tension. However, if the stress is chronic, the resulting permanently elevated cortisol levels can contribute to anxiety and depression. This is a good time to take magnesium: it lowers cortisol levels by participating in its breakdown and inhibiting its release – a possible mechanism for the anxiety-relieving effect of magnesium.

# Magnesium has a positive effect on neurotransmitters

Magnesium can also help to harmonise the neurotransmitter system. Neurotransmitters are chemical messengers. They play a fundamental role in the transmission of information between nerve cells by docking onto a receptor and passing on their message. When you are stressed, your brain releases stimulating neurotransmitters – the most important of which is the neurochemical glutamate. When you relax again, calming neurotransmitters take over, primarily gamma-aminobutyric acid (GABA). However, if the neurotransmitter system becomes unbalanced, for example due to an excess of stimulating neurotransmitters, your nerves can become overstrained. The result: you feel stressed or anxious. Magnesium can curb the release of activating glutamate while enhancing the effect of calming gamma-aminobutyric acid.

You can consume magnesium both through food and, in addition, in the form of dietary supplements.

Food sources

Magnesium is found in numerous animal and plant-based foods. The most important sources of magnesium include whole grains, green leafy vegetables, legumes, nuts, seeds, fish and seafood. Meat, potatoes and bananas can also contribute to magnesium intake.

Supplements

Although many foods contain magnesium, meeting your needs through diet alone can be challenging. If your intake is suboptimal, dietary supplements can help. They are particularly suitable as support during stressful times and if you are already suffering from a deficiency.

Magnesium can basically be divided into organic and inorganic compounds. While organic magnesium compounds are more soluble, inorganic compounds are less soluble but have a higher magnesium content. The following two forms of magnesium are suitable for treating depression and anxiety, for example:

• Magnesium citrate: In this easily absorbable form of magnesium, the active ingredient is bound to citric acid. It is one of the best-known types of magnesium.
• Magnesium glycinate: In magnesium glycinate, the mineral is bound to the amino acid glycine. This allows magnesium to be absorbed by the body as an amino acid and does not compete with other minerals for absorption, as is usually the case.
• Magnesium L-threonate: In this magnesium compound, the active ingredient is bound to L-threonic acid, a vitamin C metabolite.
• Magnesium taurate: This compound contains the amino sulfonic acid taurine, which also has a modulating effect on the nervous system.

To ensure that all your bodily functions that depend on magnesium are working optimally, experts recommend the following daily dose:

• For men: 400–420 mg
• For women: 310–320 mg

Magnesium is a multi-talented mineral that not only supports strong bones and teeth, healthy cells, a well-functioning heart and smooth muscle tension and relaxation, but also boosts mood, can shield against anxiety and depression, and helps us sleep better. A balanced diet with sufficient magnesium sources is therefore essential. In certain situations, taking high-quality dietary supplements can also be beneficial.
