Should we take magnesium for depression?

About last week, my friend, Tolu was advised to increase her magnesium intake to better the depression she feels. This made me wonder what magnesium has got to do with depression.

From my research I realized that truly, magnesium plays a role in our mental health and should not be taken lightly.

Can magnesium really work for depression? 

Indeed, there is a relationship between magnesium and mental health. Magnesium is even nicknamed “the original chill pill”. 

According to research, magnesium deficiency may make you more likely to develop depression or worsen pre-existing conditions.

Still, according to this research, it has been observed that depressive symptoms occur more in people with low levels of magnesium. 

Also, not having enough magnesium can increase your risk of anxiety and stress.

Researchers have undergone studies about the link between magnesium deficiency and depression. After doing it for a couple of years, they suggested that magnesium deficiency is a primary cause of major depression and other mental health problems.

Also, a study was done from 2017 in PLOS One, and it examined whether over-the-counter magnesium chloride can improve the symptoms of depression. 

For this study, the participants took 248 mg of elemental magnesium daily for 6 weeks. After that, they were allowed to stay for six more weeks with no intervention to compare their results. 

At the end of the research, the participating patients said that they observed improvement when using magnesium. According to them, 61% of the participants said they would continue taking magnesium for depression to better their mood.

However, whether you should get magnesium from supplements or food is another thing entirely. We will look at this more in a subsequent session.

How does magnesium work for depression? 

The following are ways magnesium helps boost your mood.

  1. Magnesium regulates your hormones

Magnesium helps regulate some hormones in your body. These hormones include: 

Cortisol

Cortisol is the stress hormone, and magnesium helps regulate its level in the body.

It prevents your body from producing it in excess and calms your nervous system. since stress triggers the production of cortisol,  calming your nervous system prevents the stress from affecting you. 

When your cortisol level is balanced, it will contribute to balancing your other hormones like progesterone, estrogen, testosterone, luteinizing hormone, and follicle-stimulating hormone. 

Serotonin

Serotonin is needed by the body to stabilize mood. The level of this hormone in your body is dependent on the amount of magnesium you have. 

Beyond your moods, serotonin also affects your appetite, cognitive functions, emotions, and other essential functions of your body.

Thanks to research, it has been found that taking magnesium for depression can increase your serotonin level. 

Here are other ways to increase serotonin in your body. 

Thyroid 

 Having an underactive thyroid also causes the symptoms of depression. So, it is vital to keep your thyroid healthy. Magnesium is a mineral that assists the production of thyroid hormones

Because of the anti-inflammatory properties of magnesium, it also offers protective benefits to your thyroid.

Hormone creation

Magnesium is a helpful mineral that assists the creation of some types of hormones in the body like progesterone and estrogen, and testosterone. 

It is very vital, especially when patients get older and their reproductive hormones start declining naturally. 

  1.  Magnesium reduces sugar cravings

No doubt, processed food and sugars are things we should avoid when battling depression. And taking magnesium has been found to reduce sugar cravings.

However, that is not all. 

Taking magnesium has a significant impact on balancing blood sugar since it controls the production of insulin.

This function is beneficial to all, especially those with diabetes or polycystic ovarian syndrome, which negatively impact insulin. 

  1. Magnesium makes you sleep better  and boost your energy 

Insomnia, low energy, and depression fatigue are prevalent symptoms of depression.

Taking magnesium for depression can help people that find it hard to fall asleep. 

You can also get this effect from herbal teas. Learn more about herbal teas for depression here.

This is because magnesium helps your body maintain healthy   GABA (gamma aminobutyric acid) levels, making it possible to have deeper and more restorative sleep.  

The central nervous system has GABA as a primary inhibitory neurotransmitter. It is vital for promoting sleep. 

Most sleep medications are targeted to affect the GABA and improve sleep. However, magnesium does this same work without the awful side effects of the drugs. 

Magnesium also helps improve sleep by dealing with restless leg syndrome, significantly disrupting a person’s sleep. 

Restless leg syndrome makes patients feel an uncomfortable sensation in the leg and move their legs frequently to ease the feeling; sometimes, it affects the arms.  This condition is associated with anxiety and depression.  

However, a study showed that taking magnesium for depression can reduce the symptoms of restless leg syndrome. 

Since your level of sleep directly impacts your energy during the day, taking magnesium will help give an energy boost. But besides this, magnesium also helps in producing adenosine triphosphate (ATP).

Adenosine triphosphate (ATP) depends on magnesium for its production. And for it to be biologically active, it has two combined with magnesium. 

When this combination occurs, it powers numerous body processes, including every metabolic process necessary to help you eat and convert the food to energy.

  1.  Magnesium reduces stress and stabilizes your mood

Magnesium regulates the way the body responds to stress by managing the body’s stress response system. Because of its positive impact on GABA, it stabilizes your mood and reduces stress. 

This is why people with healthy GABA levels are less likely to have anxiety.

The body’s stress response system is a part of the autonomic nervous system, which generates the fight-or-flight response. 

The autonomic nervous system includes two systems: the sympathetic nervous system (SNS) and parasympathetic nervous system (PNS). 

When you encounter stress, the SNS puts up the fight or flight response and tells your adrenal gland to increase the amount of adrenaline and cortisol. This causes symptoms like increased heart and breathing rate. 

After the threat goes, your body should return to normal. However, when you are facing chronic stress, your body stays in the fight or flight mode for a long time, thereby leading to wear and tear of the body. 

Taking magnesium can help regulate this response and make it easier for your body to handle.  

It can reduce the risk of depression in people facing chronic stress.  According to research, taking enough magnesium can help reduce mild to moderate depression and mild to moderate anxiety. 

  1.  Magnesium boosts cognitive functions 

When depressed, people find it difficult to concentrate and focus and have poor memory. 

According to researchers, it has been concluded the magnesium can improve a person’s cognitive ability

Research done earlier on this subject showed that taking magnesium for depression could promote synaptic plasticity.  

Brain plasticity is defined as the ability of the brain to modify its connection to rewire itself essentially.  This is why the brain can develop throughout human life and recover after being injured.

  1. Magnesium reduces pain

Magnesium has been a traditional pain relief for years, and since physical pain is one of the manifestations of depression, it is a helpful remedy.

Taking magnesium has been found to improve back, joint, and muscle pain. Research also showed that patients with fibromyalgia had reduced symptoms of depression and tender point pain when they took magnesium supplements. 

These two sets of symptoms were also found to be higher in people with this condition when their magnesium level is low

Again, magnesium has been found to alleviate headaches. This research showed that magnesium deficiency increases a person’s risk of migraine headaches, amongst others. 

So, if the deficiency contributes to depression and headache, then replenishing the deficient mineral will alleviate the symptoms.

  1. Magnesium can reduce premenstrual syndrome (PMS) symptoms

Symptoms of PMS are common for about 90% of women. This is because of the changes that occur in their bodies before their menstrual period.

However, it has been discovered that taking magnesium around the beginning of your menstrual period can help reduce the symptoms of PMS. 

The symptoms of PMS that magnesium for depression makes more tolerable include bloating, anxiety, mood swings, irritability, and tension.
