By gaining a deeper understanding of this essential mineral and its impact on our health, we can take proactive steps to optimize magnesium levels and safeguard our well-being.

Magnesium Deficiency Causes, Symptoms


Magnesium Deficiency Symptoms

As mentioned above, life without magnesium is simply not possible. Magnesium deficiency (or magnesium withdrawal) manifests itself in the following symptoms:

  • Tremors and muscle cramps (including menstrual pain)
  • Skin tingling and burning sensations (paresthesia)
  • Heart palpitations
  • Painful menstruation
  • Insomnia and sleep disorders
  • Migraines

Low magnesium can impair cognitive function and contribute to long-term feelings of fatigue and exhaustion. Magnesium is essential for the breakdown of the high-energy molecule ATP, which powers muscles and other cells.

Prolonged magnesium deficiency often leads to cardiovascular diseases, high blood pressure, diabetes, anxiety, and osteoporosis.

Who is at Risk of Magnesium Deficiency?

It is estimated that up to 30% of the Czech population suffers from magnesium deficiency. The main sources of magnesium are nuts, certain vegetables, and mineral water. Adequate magnesium intake, therefore, depends on the composition of one's diet. Due to the lack of dietary diversity, for example, 57% of the population in the United States does not consume the recommended daily intake of magnesium.

Moreover, some magnesium may not be absorbed or may bind to other components of food during the digestion process and be excreted from the body. Low magnesium levels also affect individuals with kidney and intestinal disorders, diabetics, and those who regularly consume alcohol in large quantities.

Magnesium Deficiency Caused by Medications

The following medications can contribute to magnesium deficiency:

  • Loop and thiazide diuretics
  • Aminoglycoside and other antibiotics
  • Proton pump inhibitors (medications used to reduce stomach acidity)

Magnesium during Pregnancy and Breastfeeding

Adequate magnesium intake should be a concern for pregnant women as well. This element is essential for the development of the fetus and reduces the risk of low birth weight. According to a 2017 study, a magnesium intake of 300 mg - in the form of dietary supplements - reduces the occurrence of morning sickness during pregnancy. Magnesium also acts as a preventive measure against the development of preeclampsia, a condition characterized by increased blood pressure and protein leakage into the urine due to increased blood clotting.

Higher magnesium intake is also important for breastfeeding women. In the first weeks of life, infants primarily obtain magnesium through breast milk.

How Much Magnesium and in What Form Should You Take?

Recommended daily magnesium intakes according to the European Food Safety Authority (EFSA) are as follows:

  • Children from 7 to 11 months: 80 mg
  • Children from 1 to 2 years: 170 mg
  • Children from 3 to 9 years: 230 mg
  • Children from 10 to 17 years: 250 mg
  • Adult women: 300 mg
  • Adult men: 350 mg

Pregnant women should consume 310 mg of magnesium daily, while breastfeeding women should aim for up to 390 mg (100 ml of breast milk contains 3 mg of magnesium). People with increased physical exertion, especially athletes, are advised to increase their magnesium intake by an additional 10-20%. The same applies to individuals who consume higher amounts of coffee and caffeine, which deplete magnesium.


6 Reasons to Address Your Magnesium Intake

Magnesium is more important for our bodies than we may realize. Let's explore five reasons why it is essential to ensure an adequate intake of magnesium in our diets.

  1. To Avoid Fatigue

Magnesium is necessary for deriving energy from carbohydrates, fats, and proteins. It is involved in the breakdown of glucose, which the body can then use as fuel. A deficiency of magnesium can lead to weakness and fatigue because the body is unable to efficiently convert food into energy.

  1. Magnesium Helps with Insomnia

Magnesium is required for glands to begin producing hormones necessary for deep sleep. It also induces a state of relaxation before bedtime. Additionally, studies have shown that taking magnesium supplements increases the production of melatonin, a hormone that helps regulate the sleep cycle.

  1. Magnesium Helps with Menstrual Pain and Water Retention

Having magnesium on hand is beneficial if you experience painful menstruation. Magnesium powder is the most rapidly absorbed form. Magnesium supports the function of nerves and muscles involved in the menstrual cycle and helps prevent water retention, a common issue for women during menstruation. Moreover, it provides energy and aids in stress reduction and mood swings.

  1. Faster Recovery After Exercise

Athletes often face the problem of losing significant amounts of magnesium during exercise, making it crucial for them to increase their intake of magnesium-rich foods. A deficiency of magnesium can lead to muscle damage and, consequently, prolonged recovery time after exercise. Athletes should ensure they consume foods rich in magnesium or consider magnesium supplements.

  1. Magnesium for Hangover Relief

Magnesium is one of the components that should be replenished after consuming alcohol. Even after a few drinks, you can wake up with a clear head by taking a hangover supplement like Mindflow Hangover. It effectively eliminates harmful substances, protects the body from damage, prevents acidification, and helps with blood sugar regulation.

  1. Magnesium Supports the Immune System

Magnesium is crucial for a strong immune system. It helps strengthen muscles and bones and supports various bodily functions, from heart function to brain health. Magnesium deficiency has been linked to several diseases, including infections and cancer. Studies have shown that the progression of cancer in mice was accelerated when they were given a low-magnesium diet, and their resistance to influenza viruses was weakened.

Magnesium Sources: Foods and Supplements

Magnesium-rich foods include nuts, seeds, and certain types of vegetables. Cereals and halibut meat are also high in magnesium. The following table summarizes the most significant sources of this mineral:

  • Pumpkin seeds: 947 mg per 100 g
  • Chia seeds: 506 mg per 100 g
  • Brazil nuts: 391 mg per 100 g
  • Buckwheat: 236 mg per 100 g
  • Sunflower seeds: 128 mg per 100 g
  • Cooked spinach: 123 mg per 100 g
  • Halibut meat: 121 mg per 100 g
  • Cooked black beans: 94 mg per 100 g
  • Cooked lentils: 56 mg per 100 g
  • Oatmeal: 50 mg per 100 g

Mineral water is also a significant source of magnesium. Bottled mineral water can contain up to 170 mg of magnesium per liter, while highly mineralized waters can contain up to 2 grams per liter.

Magnesium is almost non-existent in industrially processed foods due to its high solubility in water. During food production, magnesium is often washed out. The same applies to meat.

The Best Forms of Magnesium

The most bioavailable and absorbable forms of magnesium are considered to be magnesium citrate, magnesium aspartate, and magnesium gluconate. These forms are often regarded as the best choice for individuals needing to supplement their daily magnesium intake, as they are easily absorbed and well-tolerated.

Magnesium supplements are available on the market and can be taken in various forms. It is recommended to choose a powdered form over tablets, as the latter requires stomach acid to ionize the mineral, resulting in lower absorption and higher excretion. For example, Magnesium Complex is a suitable choice as it contains not only magnesium but also substances that enhance its absorption. It also includes compounds that support the proper functioning of the nervous system, such as vitamins B1 and B6.

How to Take Magnesium Correctly

We recommend opting for powdered forms rather than tablets. Magnesium in tablet form requires stomach acid to ionize the mineral. As a result, absorption is lower, and more magnesium is excreted. Magnesium Complex is a suitable option as it contains substances that enhance its absorption into the body. It is advisable to take magnesium supplements with meals. Like many other dietary supplements, taking magnesium on an empty stomach may disrupt the digestive system, causing nausea, stomach discomfort, and diarrhea.
