Everything You Need To Know About Magnesium

History of Magnesium


Magnesium makes up 2 percent of the Earth’s crust, but you won’t see this silvery, light metal in nature. This versatile element occurs naturally only in combination with other elements, such as carbon, calcium and oxygen.

Magnesium wasn’t purified until 1808, when Cornish chemist Sir Humphry Davy, who created a small amount by running an electrical current through magnesium oxide, according to the Royal Society of Chemistry. In 1831, French chemist Antoine Bussy was the first to create a significant amount of pure magnesium, according to the RSC.

As a metal, magnesium can be mixed with other metals, particularly aluminium, for use in making car bodies, drink cans and other items that need to be light and strong. Magnesium is flammable, so one of its main uses is for flares and fireworks. During World War II, the element was even used to make incendiary bombs.




The word “magnesium” comes from the name of the Greek region Magnesia, where compounds of this element occur naturally.

Milk of Magnesia, which works as a laxative and to treat indigestion, is a compound of magnesium, hydrogen and oxygen molecules.

Another home remedy owed to magnesium? Epsom salts, otherwise known as magnesium sulphate. The name “Epsom” comes from a spring in England where the salts occur naturally.

Magnesium is vital for the proper functioning of hundreds of enzymes.

Consuming adequate magnesium might help reduce premenstrual symptoms.

Magnesium supplements can interact with different drugs, so it is best to check with a doctor before taking them.



Magnesium within the Body

An abundant element on our planet, magnesium is also present in every organ in the human body. In fact, it is considered a vital mineral for over 300 biochemical reactions in our body, that regulate our health and wellness. Magnesium is crucial to nerve transmission, blood coagulation, energy production, the metabolism of food and synthesis of fatty acids and proteins.

Sadly, many of us simply don’t get enough magnesium in our bodies to the point that we unknowingly suffer from a magnesium deficiency.

Many of the symptoms of low magnesium are not unique to magnesium deficiency, making it difficult to diagnose with 100% accuracy. Thus quite often low magnesium levels go completely unrecognized… and untreated.

Yet chronic low intake of magnesium is not only extremely common but linked to several disease states, indicating the importance of considering both overt physical symptoms and the presence of other diseases and conditions when considering magnesium status.

The symptoms of a magnesium deficit fall into two broad categories – the physical symptoms of overt deficiency and the spectrum of disease states linked to low magnesium levels.



Magnesium Deficiency Symptoms

Classic “Clinical” Symptoms.
These physical signs of magnesium deficiency are clearly related to both its physiological role and its significant impact on the healthy balance of minerals such as calcium and potassium.




 “Sub-clinical” or “Latent” Symptoms.
These symptoms are present but concealed by an inability to distinguish their signs from other disease states.


  • Depression
  • Chronic fatigue syndrome
  • ADHD
  • Epilepsy
  • Parkinson’s disease
  • Sleep problems
  • Migraine
  • Cluster headaches
  • Osteoporosis
  • Premenstrual syndrome
  • Chest pain (angina)
  • Cardiac arrhythmias
  • Coronary artery disease and atherosclerosis
  • Hypertension
  • Type II diabetes
  • Asthma



Becoming Magnesium Deficient

In our current era of fast-food, excessive salt and sugar, additives, preservatives, and chemical-based fertilizer, pesticides, and crop enhancers, now more than ever, what we consume has lasting effects on our bodies and health. Studies have shown that 1/3 adults aren’t getting their recommended daily magnesium through their diet.


Magnesium depletion in healthy individuals can be caused by:

  • Low magnesium diets, processed foods and sodas
  • Water filtration and chemicalising
  • Calcium supplements
  • Prescription and over the counter medications


Some conditions can increase vulnerability to deficiency, including: 

  • Alcohol and other addictions
  • Aging, illness and stress
  • Digestive and Genetic disorders



Magnesium Rich Foods



Magnesium-rich foods include whole grains, leafy greens, nuts and seeds. Foods like these were once common in diets around the world, but an increase in both food processing and the availability of enticing convenience foods with added fats and sugars has had its impact. Whole and unrefined foods high in magnesium are becoming increasingly rare in the modern diet.


  • Green leafy vegetables (e.g. spinach and kale)
  • Fruit (figs, avocado, banana and raspberries)
  • Nuts and seeds
  • Legumes (black beans, chickpeas and kidney beans)
  • Vegetables (peas, broccoli, cabbage, green beans, artichokes, asparagus, brussels sprouts)
  • Seafood (salmon, mackerel, tuna)
  • Whole grains (brown rice and oats)
  • Raw cacao
  • Dark Chocolate
  • Tofu
  • Baked beans
  • Chlorella powder



Health Benefits of Magnesium

Magnesium has many benefits throughout all the body’s critical functions. From nerves to cells to muscles, magnesium is hard at work regulating and promoting proper function.


• Helps Increase Energy

Magnesium is used to create “energy” in your body by activating adenosine triphosphate, also known as ATP. This means that without enough magnesium, you may not have the energy you need and could suffer from fatigue more easily.


• Calms Nerves and Anxiety

Magnesium is vital for GABA function, an inhibitory neurotransmitter that produces “happy hormones” like serotonin. Certain hormones regulated by magnesium are crucial for calming the brain and promoting relaxation, which is one reason a magnesium deficiency may lead to sleeplessness or insomnia.


• Treats Insomnia and Helps You Fall Asleep

To fall asleep and stay asleep, your body and brain need to relax.  On a chemical level, magnesium aids this process by activating the parasympathetic nervous system, the system responsible for getting you calm and relaxed. Our circadian rhythms shift, especially as we age because of our decreased nutrient consumption and a lower nutrient absorption, which puts many of us at risk for insomnia.


• Helps with Digestion by Relieving Constipation

Magnesium has shown to help relax muscles within the digestive tract, including the intestinal wall, which controls your ability to go to the bathroom. Because magnesium helps neutralize stomach acid and moves stool through the intestines, taking magnesium supplements is a natural way to help you poop! Keep in mind, however, that if you experience a laxative effect when taking magnesium supplements, you may be taking too high of a dose. Taking the proper dose of magnesium should help you go to the bathroom easily on a normal schedule but shouldn’t cause discomfort or diarrhea.


• Relieves Muscle Aches and Spasms

Magnesium has an important role in neuromuscular signals and muscle contractions. When our bodies don’t acquire enough magnesium, our muscles can go into spasms (eg. Restless Leg Syndrome). Magnesium helps muscles relax and contract. Additionally, magnesium balances calcium within the body, which is important because overly high doses of calcium, usually from supplements, can cause problems associated with muscle control, including controlling the heart.


• Regulates Levels of Calcium, Potassium, and Sodium

Together with other electrolytes, magnesium regulates diverse biochemical reactions in the body. Magnesium plays a role in the active transport of calcium and potassium ions across cell membranes. This makes magnesium vital to nerve impulse conductions, muscle contractions and normal heart rhythms.


• Important for Heart Health

Magnesium has been shown to be very important for heart health. The highest amount of magnesium within the whole body is in the heart, specifically within the heart’s left ventricle. Magnesium works with calcium to support proper blood pressure levels and prevent hypertension.


• Prevents Migraine Headaches

Because magnesium is involved in neurotransmitter function and blood circulation, it can help control migraine headache pain by releasing pain-reducing hormones and reducing vasoconstriction, or constriction of the blood vessels that raises blood pressure. Several studies show that when sufferers of migraines supplement with magnesium, their symptoms improve.


• Helps Prevent Osteoporosis

Magnesium is needed for the proper bone formation and influences the activities of osteoblasts and osteoclasts that build healthy bone density.



Taking Magnesium Supplements


There are a variety of supplements on the market for increasing your magnesium levels. We’re going to look at the difference between oral magnesium (taken by mouth) and topical magnesium (applied to the skin). Both oral and topical magnesium can increase your body’s magnesium levels, but rates of absorption and potential side-effects can vary.




Which is Better?
With several forms of magnesium available, there’s something for everyone! You may even use topical magnesium in combination with oral supplements to provide an extra boost of magnesium.

In fact, topical and oral magnesium both offer great benefits, so it’s hard to say whether one is ultimately better than the other. What this really comes down to is personal preference.

It is important to consider how much magnesium you need, how often you must take the supplement, which option you are more likely to stick with and which one you feel benefits you the most overall.



Be sure to speak with your healthcare professional before taking any magnesium supplements and follow directions appropriately. If you suffer from any side effects, it is best to discontinue supplement use until you consult with your doctor.
