What Is Magnesium? Overview And Benefits

Magnesium is an essential mineral that plays a crucial role in maintaining our overall health and wellness. From supporting bone health to regulating heart function and aiding in stress management, the benefits of magnesium are numerous and far-reaching.

Magnesium supplements are available in various forms, including magnesium oxide, magnesium citrate, magnesium glycinate, and magnesium chloride, among others. The type of magnesium supplement you choose may affect its absorption and bioavailability.

There are a whole host of benefits linked to magnesium supplementation that include:

  • Promotes restfulness which makes it easier to fall asleep and remain in deep sleep
  • It helps to improve strength and hypertrophy by promoting muscle recovery
  • Increases natural levels of testosterone 
  • Increases energy capacity which prevents mid-day slumps
  • Decreases anxiety with relaxation properties
  • Decreases depression with mood-boosting properties
  • Prevents the regular occurrence of headaches and migraines

Whilst there is evidence to support some of these claims, further research is ultimately required to back all of them sufficiently.

Let’s take a look at the science behind each of these benefits in more detail:

Promotes Restfulness

Magnesium is known to promote restfulness and relaxation by regulating neurotransmitters and hormones in the body. It helps regulate the production and release of melatonin, a hormone responsible for inducing sleep, as well as calming the central nervous system.1

Magnesium supplementation has also been shown to improve sleep in individuals with insomnia,2 making it a valuable nutrient for those seeking to improve their sleep and overall sense of well-being.

Antagonising all of your problems and dealing with racing thoughts can be slowed down by magnesium. So you can close your eyes and rest assured, have a more assured rest.

Helps Improve Strength And Hypertrophy

Magnesium is a mineral that plays an important role in muscle function and growth. By regulating muscle contractions and nerve impulses, magnesium ensures that muscles can work efficiently during exercise. It also supports protein synthesis, which is crucial for muscle growth and repair.3

Additionally, magnesium can reduce muscle fatigue and cramps, making it easier for individuals to complete their workouts. Although various studies have found no solid evidence for the link between magnesium and the reduction of muscle cramps.

Furthermore, magnesium helps balance hormones involved in muscle growth, such as testosterone, and improves insulin sensitivity, allowing for better nutrient uptake by muscles. These benefits of magnesium can contribute to improved strength and hypertrophy over time, making it a valuable nutrient for those looking to build muscle.

Boosts Testosterone

Magnesium plays a crucial role in boosting testosterone levels by regulating hormones involved in testosterone production and utilization. It helps increase luteinizing hormone (LH) production, which stimulates the production of testosterone in the testes.4 Studies also suggest that magnesium increases testosterone by controlling both muscle mass and bone density. 5

Additionally, magnesium can reduce oxidative stress, which can lead to lower testosterone levels, and improve overall energy production in the body, providing a better environment for testosterone production. Higher levels of testosterone can lead to more energy, more muscle mass, a higher sex drive and an improved state of well-being.

Increased Energy Capacity

Starting the day off productively is an excellent habit to have. It can get you a long way and can allow you to get important tasks completed. But when the middle of the day comes around and you almost feel incapable of even holding a conversation, never mind being productive. If you suffer from a mid-afternoon crash then you are not alone.

Magnesium deficiency causes fatigue and the reliance on multiple hits of caffeine simply to make it through the day. All this caffeine may be good to complete your work, but not good for your longevity nor is it any better for a restful night’s sleep which has many problems of its own. 

Magnesium plays a crucial role in regulating blood flow and functions within the muscles and nervous system. Magnesium molecules assist in the transportation of food and how it is distributed around the body for the most productive use. This process includes converting glucose from food into energy, which can replace the reliance on caffeine. 6

Therefore, magnesium helps steady your energy levels to remain in a more stable condition rather than fluctuating throughout the day.

Decreases Symptoms Of Anxiety And Depression

Magnesium plays a crucial role in improving symptoms of anxiety and depression by regulating neurotransmitter production and function. It helps balance levels of GABA, a neurotransmitter that promotes calmness and relaxation, as well as reducing the effects of stress hormones such as cortisol.7

Additionally, magnesium can reduce oxidative stress and inflammation, which can contribute to feelings of anxiety and depression.8 It also helps improve insulin sensitivity and blood sugar control, which can help reduce mood swings and brain fog.9

By supporting healthy stress responses and improving overall brain function, magnesium can help alleviate symptoms of anxiety and depression, leading to improved overall mental well-being.

You may have recognised the pattern between magnesium and its calming effects on the body. The benefits of magnesium have the ability to put the body into a calmer, more relaxed state both physically and mentally. 10

If the muscles and cells in your body are relaxed it will cause your mind to do the same thing. It is important to recognise how a healthy body transfers over into a healthy mind.

Prevention Of Headaches And Migraines

Magnesium can help reduce headaches and migraines by regulating neurotransmitter activity and relaxing constricted blood vessels in the head. It helps balance levels of neurotransmitters involved in pain perception, such as glutamate and GABA, reducing headache frequency and intensity.11

Additionally, magnesium helps dilate blood vessels and reduce muscle tension, which can be a trigger for headaches and migraines.12 By reducing inflammation and oxidative stress, magnesium can also improve overall brain function and reduce the frequency of headaches and migraines.

Magnesium supplementation has been shown to be an effective method for reducing headache and migraine frequency and severity, making it a valuable nutrient for those seeking to improve their headache and migraine symptoms.

A lack of magnesium can also be often found in people who suffer from regular headaches or migraines.13

Different Types Of Magnesium

There are several different types of magnesium supplements available, and each type has its own unique characteristics and benefits. Here are 5 of the most common types of magnesium supplements:

  • Magnesium Oxide
  • Magnesium Citrate
  • Magnesium Glycinate
  • Magnesium Chloride
  • Magnesium Threonate

It is important to note that the effectiveness of a magnesium supplement may depend on factors such as the individual’s health status, diet, and absorption ability. Let’s take a look at each of these types of magnesium individually, so you can decide which is the best choice for you:

Magnesium Oxide

Magnesium oxide is a type of magnesium supplement that has a high concentration of magnesium. It is commonly used to help alleviate constipation and acid reflux symptoms.

Magnesium oxide is also known to support healthy bone and teeth development, and it may also help improve sleep quality in some individuals. However, it is not as well absorbed as some other forms of magnesium, which may limit its effectiveness for some people.

Magnesium Citrate

Magnesium citrate is a form of magnesium that is bound to citric acid. It is a highly soluble and easily absorbed form of magnesium, making it a popular choice for magnesium supplementation. The most common use is to treat conditions related to magnesium deficiency, such as constipation, muscle cramps, and headaches.

It may also help improve bone health, reduce the risk of heart disease, and enhance sleep quality. 

Magnesium Glycinate

Magnesium glycinate is a form of magnesium that is bound to the amino acid glycine. It is considered a highly bioavailable form of magnesium, meaning it is easily absorbed and utilized by the body. Magnesium glycinate is commonly used to treat conditions related to magnesium deficiency, such as anxiety, depression, and muscle cramps.

It may also help improve bone health, reduce the risk of heart disease, and enhance sleep quality. Unlike some forms of magnesium, magnesium glycinate is less likely to cause digestive side effects, such as diarrhoea and stomach cramping.

Magnesium Chloride

Magnesium chloride is a type of magnesium supplement that is often used topically as a spray or lotion to help alleviate muscle pain, tension, and cramping. It may also be taken orally and is well-absorbed by the body.

Magnesium chloride has been shown to support healthy immune system function, maintain healthy blood pressure levels, and improve athletic performance in some studies. Additionally, it may help support healthy skin and improve wound healing.

Magnesium Theronate

Magnesium threonate is a newer form of magnesium that is believed to be particularly effective at crossing the blood-brain barrier, which may make it beneficial for cognitive health and brain function. It has been shown in some studies to support healthy memory and learning, as well as alleviate symptoms of depression and anxiety.

Magnesium threonate may also support healthy sleep patterns and help reduce symptoms of chronic pain.
