Magnesium Benefits: The Mineral Your Body Needs

Magnesium Benefits: The Mineral Your Body Needs



What is Magnesium

When it comes to living a healthy life, we often focus on what we eat and how much we exercise, but we forget the importance of essential minerals in our diets. One of these minerals, magnesium, is critical for our health and well-being. Magnesium helps our bodies carry out over 300 biochemical reactions, such as maintaining nerve and muscle function and regulating blood pressure. In this article, we’ll discuss the many benefits of magnesium and why you should include it in your diet. There are many magnesium benefits.

Magnesium is a crucial mineral that your body needs to function correctly. It’s one of the seven macrominerals, minerals that need to be consumed in relatively large amounts — at least 100 milligrams (mg) daily. An adult body contains around 25 grams of magnesium, and over half is in the skeletal system. The rest is found in muscles, soft tissues, and bodily fluids. It is vital in many bodily functions, including energy creation, protein formation, gene maintenance, muscle movements, and nervous system regulation.

Magnesium Sources in Nature


Magnesium Food Sources


Magnesium is an essential mineral that is crucial to overall health and well-being. Fortunately, there are many delicious foods rich in magnesium that we can enjoy every day. Spinach and kale are excellent plant-based sources of magnesium, containing up to 157mg and 47mg per cup, respectively. Whole grains, legumes, seeds, and nuts are also good sources of magnesium, with pumpkin seeds being exceptionally high at 150mg per quarter cup. Fish and meat are also magnesium-rich, with salmon and beef boasting around 26mg and 23mg per 3oz respectively. And let’s not forget everyone’s favorite superfood, avocado, which contains around 58mg per whole fruit. Incorporating these magnesium foods into our diets can help us get the nutrients needed to thrive.


Magnesium Benefits

1) Magnesium helps with energy production: Magnesium is crucial in converting food into energy our body can use. Without magnesium, our body cannot create the energy it needs to function. Ensuring an adequate magnesium intake can help prevent fatigue and boost energy levels.

2) Magnesium supports heart health: Magnesium contributes to healthy blood pressure and regulates heart function, reducing the risk of heart disease and stroke. People who consume enough magnesium have a lower chance of developing heart disease.

3) Magnesium promotes bone health: Magnesium works with other minerals, such as calcium and vitamin D, to keep our bones healthy and strong. A magnesium deficiency can lead to bone density loss, putting you at risk for fractures and osteoporosis.

4) Magnesium supports mental health: Magnesium helps regulate neurotransmitters that influence our mood and behavior. People with depression, anxiety, and other mental health issues may have lower magnesium levels in their bodies. Studies have shown that magnesium can help reduce symptoms of these conditions.

5) Magnesium aids in digestive health: Magnesium helps regulate muscle contractions in the digestive tract, keeping food moving smoothly through the intestines. It can also help prevent constipation and act as a natural laxative.

Magnesium Deficiency Signs and Symptoms


Magnesium deficiency, although uncommon, can manifest in several ways. Some people may not exhibit any symptoms, especially in the early stages of depletion. However, signs and symptoms may become more apparent as the deficiency progresses. Here are some of the critical signs and symptoms associated with magnesium deficiency:

1) Fatigue and muscle weakness: As magnesium is crucial for energy production, a deficiency can result in tiredness, fatigue, and muscle weakness.

2) Loss of appetite: A decreased appetite could indicate magnesium deficiency.

3) Nausea and vomiting are common symptoms of a lack of magnesium.

4) Numbness and tingling: These symptoms usually occur in the hands and feet and can indicate severe magnesium deficiency.

5) Muscle cramps and contractions: Inadequate magnesium levels can lead to involuntary muscle cramps and contractions.

6) Irregular heartbeat: Magnesium is vital in maintaining heart health; its deficiency can lead to abnormal or irregular heart rhythms.

If you’re experiencing any of these symptoms, it’s crucial to consult with a healthcare provider. They can test your magnesium levels and provide appropriate treatment options. While these symptoms may be associated with magnesium deficiency, they can also signify other health conditions. It’s essential to get a proper diagnosis.

How to Test for Magnesium Deficiency


Testing for magnesium deficiency is not as straightforward as other mineral deficiencies because most of the body’s magnesium is stored in the bones and inside cells, making it difficult to measure through a simple blood test. However, healthcare providers use several methods to determine if a person is deficient in magnesium.

1) Serum Magnesium Test: The most common method is a serum magnesium test, which measures the amount of magnesium in the blood. Despite its common use, this test is not always accurate because only 1% of magnesium is in the blood.

2) Intracellular Magnesium Test: Another method is the intracellular magnesium test, which evaluates magnesium levels in the cells. This test is more accurate than the serum magnesium as it measures most of the body’s magnesium.

3) 24-Hour Urinary Magnesium Test: This test measures the amount of magnesium excreted in the urine over 24 hours. It can help determine whether the body is retaining or wasting magnesium.

4) Sublingual Epithelial Cell Mg Test involves scraping cells under the tongue to measure their magnesium levels. It gives a more accurate picture of body magnesium status as these cells represent a specific type of magnesium found in heart and muscle cells.

Always consult your healthcare provider if you suspect a magnesium deficiency. They can recommend the most suitable test and interpret the results accurately. Remember, self-diagnosis can lead to unnecessary worry or inappropriate use of supplements.

Daily Intake Requirements for Magnesium


Magnesium’s recommended daily intake (RDI) varies depending on age, gender, and physiological state. Below are the general guidelines for daily magnesium intake provided by the National Institutes of Health:

  • Infants up to 6 months old: 30 milligrams
  • Infants 7-12 months old: 75 milligrams
  • Children 1-3 years old: 80 milligrams
  • Children 4-8 years old: 130 milligrams
  • Children 9-13 years old: 240 milligrams
  • Teenagers 14-18 years old: 410 milligrams for males and 360 milligrams for females
  • Adults 19-30 years old: 400 milligrams for males and 310 milligrams for females
  • Adults 31 years and older: 420 milligrams for males and 320 milligrams for females
  • Pregnant women: 350-360 milligrams
  • Breastfeeding women: 310-320 milligrams

Please note that individual needs may vary. It’s always best to consult a healthcare provider or a registered dietitian to determine your magnesium requirements accurately.


Magnesium is an essential mineral that should not be overlooked. It contributes to various critical bodily functions, from energy production and heart health to bone and mental health. Unfortunately, many people do not consume enough magnesium in their diets. Good sources of magnesium are dark chocolate, avocado, nuts, seeds, legumes, and leafy green vegetables. While it’s recommended that adult men and women consume 400-420 mg and 310-320 mg of magnesium daily, some people may need to supplement their diets with magnesium. Talk to your doctor to determine if you need a supplement and which type is best for you. By ensuring your body has enough magnesium, you can experience the many benefits of this vital mineral.
