22 Little Known Dangers of Magnesium Deficiency and What to Do About It

Last updated on

Next to potassium, magnesium is the second most plentiful positive-charged-ion in the cellular fluid. Magnesium is a key cofactor in more than 300 enzyme-driven biochemical reactions, and a key mineral in hundreds of functions in the body.

Sophistication Of Magnesium

The functions of magnesium in the human body is complex and sophisticated. But, some of their main functions include:

  • As a cofactor, enabling thousands of biochemical processes, including:
    — Temperature regulation
    — Breaking down of glucose and fat
    — Production of proteins, antioxidants, cholesterol
    — Creation of DNA and RNA
  • Produces energy inside mitochondria, metabolizing them into usable energy and storing them. When magnesium level is low, one can expect to feel lethargic.
  • Magnesium is a cofactor for dozens of various other nutrients to be used as building blocks to create the body structure.
  • Magnesium is necessary for electrical transmission  of our thoughts to the nervous system and to various parts of our body.
  • While calcium causes contraction of muscles, magnesium causes relaxation. In the presence of excess calcium and insufficient magnesium, crampings (of the lungs, uterus, blood vessels, legs, muscles, etc.) can occur.
  • Magnesium is required to maintain a healthy balance (“homeostasis”) of the body’s electrolytes—calcium, sodium, potassium—that affects nerve impulses, muscle contractions and heart rhythms.

Sufficient magnesium is essential to achieving the delicate balance necessary to keep the smooth-running of all these body’s functions. So you can see, in cases of magnesium deficiency, there can be a far-reaching implications for the body’s level of performance and health. Body processes and metabolism could easily spiral out of control.

Why Do You Get Magnesium Deficient

Although magnesium is the fourth most abundant mineral in a human body, the body cannot manufacture it and it must be obtained from foods and supplements.

Many diseases develop due to this reason—not eating foods that contain magnesium to replenish usage in the body. Many other factors also contribute to deficiency in this very important mineral, while at the same time, eating foods high in calcium causes various inflammation in the body.

Some of the factors that cause magnesium deficiency:

  • Soil that is deficient in minerals produce foods that are low in magnesium content.
  • Eating foods that are high in calcium. Calcium requires magnesium at the ratio of 1:1 in order to be absorbed. When excess calcium is consumed, more magnesium is needed but is not replenished.
  • Long-term medication (of any drugs) and stress deplete the body of magnesium.
  • Inefficient intestinal absorption hinders absorption of magnesium, even when ingesting foods high in magnesium.
  • Excessive consumption of high fats food (wrong kinds of fats), processed foods (with artificial food additives), sodas, salt and sugar—not only are these foods void of magnesium but in order to digest them, they further deplete the body of magnesium.
  • Drinking water that is fortified with fluoride that depletes the body of magnesium

Symptoms Of Magnesium Deficiency

Early signs of magnesium deficiency include muscle twitching (noticeably on the eyelid), loss of appetite, headache, nausea, fatigue, and weakness. An ongoing magnesium deficiency can lead to more serious symptoms, including:

  • Numbness and tingling
  • Muscle contractions and cramps
  • Seizures
  • Abnormal heart beat rate
  • Coronary spasms
  • Anxiety

As magnesium is necessary in so many bodily functions and processes, the lack of it will easily spiral things out of control.

Some of the conditions that are linked to magnesium deficiency have been recorded as follows:

Anxiety, depression, confusion, anger
Atherosclerosis and arteriosclerosis
Cardiac arrhythmias
Cholesterol oxidation
Chronic fatigue syndrome
Coronary heart disease
Diabetes (Type 2)
Inflammatory diseases
Insomnia and other sleep disorders
Kidney stones
Migraines and headaches
Muscle pain and cramps

Tips For Increasing Your Magnesium Levels

One way to really increase your magnesium, as well as many other important plant-based nutrients, is by juicing your greens. Drink one pint to one quart of fresh green vegetable juice every day as your primary source of magnesium.

Organic foods may have more magnesium if grown in nutrient-rich soils but it is very difficult to make that determination. If you opt for a supplement, be aware that there are a wide variety of magnesium supplements on the market, because magnesium must be bound to another substance.

1. Magnesium-Rich Foods

If you suspect that you’re magnesium-deficient, first of all work to reduce the factors in your lifestyle or diet that contribute to the deficiency where possible. Magnesium is best available from food sources and from supplements.

Some of the foods richest in magnesium content:

Magnesium rich foods

Boiled spinach
Brown rice
Bran cereal
Almonds and cashew nuts
Pumpkin seeds
Dark chocolate
Lima beans
Swiss chard
Dried fruits
Green vegetables

2. Magnesium Supplements

The following are suggestions of magnesium supplements in various forms. Magnesium threonate and citrate are some of the best sources, as it seems to penetrate cell membranes—including your mitochondria—which results in higher energy levels.


Additionally, it also penetrates your blood-brain barrier and seems to do wonders to treat and prevent dementia and improve memory.

  • Magnesium glycinate is a chelated form of magnesium that tends to provide the highest levels of absorption and bioavailability and is typically considered ideal for those who are trying to correct a deficiency.
  • Magnesium oxide is a non-chelated type of magnesium, bound to an organic acid or a fatty acid. Contains 60 percent magnesium, and has stool softening properties.
  • Magnesium chloride/Magnesium lactate contain only 12 percent magnesium, but has better absorption than others, such as magnesium oxide, which contains five times more magnesium.
  • Magnesium sulfate/Magnesium hydroxide (milk of magnesia) are typically used as laxatives. Be aware that it’s easy to overdose on these, so ONLY take as directed.
  • Magnesium carbonate, which has antacid properties, contains 45 percent magnesium.
  • Magnesium taurate contains a combination of magnesium and taurine, an amino acid. Together, they tend to provide a calming effect on your body and mind.
  • Magnesium citrate is magnesium with citric acid, which like most magnesium supplements has laxative properties but is well absorbed and cost effective.
  • Magnesium threonate is a newer, emerging type of magnesium supplement that appears promising, primarily due to its superior ability to penetrate the mitochondrial membrane, and may be the best magnesium supplement on the market.

3. Epsom Salt Bath Or Foot Soak

Besides taking a supplement, another way to improve your magnesium status is to take regular Epsom salt baths or foot baths. Epsom salt is a magnesium sulfate that can absorb into your body through your skin.
