Magnesium is one of the top 5 main nutrients our bodies need in order to stay healthy. If you are considering taking a magnesium supplement because you feel you do not get enough magnesium in your system, the fact is you may be among the 50 percent of people in the US and Europe who get less than the recommended daily intake of magnesium(1). There are many ways to ensure you get a diet rich in magnesium but what is the best source of magnesium? We will take a look at why you should be paying more attention to your magnesium intake.

What is Magnesium?

Magnesium is the fourth most present mineral in our body and is crucial to the functioning of our body. It helps regulate our blood pressure, makes our bones strong, and makes sure our heart maintains it’s rhythmic beat. It is found in our bones, teeth, and red blood cells and serves as a building block for our DNA.

Magnesium is vital to our nervous system because it produces blood platelets and helps maintain the density of our bones.

Benefits of Magnesium

Every cell in our body contains magnesium. Here are some of the health benefits of magnesium.

Calms nerves and anxiety

Magnesium is responsible for the functioning of the brain and is said to provide a calming effect. Studies have shown that a deficiency in magnesium can play a role in many mental health disorders including anxiety(2).

When you are stressed your body uses more amounts of magnesium. However, large amounts of stress deplete your body of this mineral. So you must ensure your body is getting adequate amounts of magnesium every day.

Prevents migraine headaches

Low magnesium in our blood has been linked to migraines so sometimes magnesium is used as a way to treat and prevent migraines.

One study(3) showed that taking magnesium regularly can prevent migraine attacks by 41.6 percent. Another study even showed that menstrual-related migraines could be prevented by taking a magnesium supplement daily (4).

Lowers your blood pressure

Research has shown that those deficient in magnesium may benefit from its use in lowering blood pressure. A study by the American Heart Association found that people who took 368 mg of magnesium over 3 months  had a reduction in systolic blood pressure of an average of 2.00 millimeters(mm) Hg of mercury and 1.78 mm Hg in diastolic pressure(4).

Helps you fall asleep

Magnesium helps relax your muscles and calm your nerves, this in return can help you fall asleep at night. In fact, magnesium is preferred by some over melatonin as the supplement of choice for insomnia.

Low levels of magnesium may be responsible when you have difficulty falling asleep. The more stressed you are the more magnesium you lose and the harder it may be to fall asleep at night.

A lack of magnesium is also responsible for leg cramps or restless leg syndrome and this can disrupt your sleep. Magnesium can stimulate activity in the sympathetic nervous system because it suppresses the release of catecholamines.

If you decide to take magnesium to help you sleep it should be taken 45 minutes before bed. First, speak with your doctor to find out the proper dosage to take.

It can improve your exercise performance

Magnesium helps increase energy by converting food into energy. It is responsible for moving sugar from our blood into our muscles during our workout and disposing of lactic acid which accumulates in our muscles and causes pain(2).

Important for the heart

Magnesium is essential to the health of our body and responsible for 300 biochemical reactions. It also maintains our hearts steady beat and blood pressure.

If magnesium levels are low, that puts you at risk for arrhythmia(irregular heartbeats) and heart palpitations(the noticeable strong, irregular, and rapid heartbeat).

Due to the fact that magnesium lowers our blood pressure and decreases the risk of arrhythmia, making sure you have a magnesium-rich diet can limit the complications of congestive heart failure.

Woman Suffering From Stomach AcheHelps with digestion

Magnesium relaxes the muscles of the wall in our digestive tract. It helps us have bowel movements by controlling the acid in our stomach. So taking magnesium is a good way to help keep you regular.

However, those with digestive issues, like Irritable Bowel Syndrome, for instance, is not recommended to take magnesium because it can cause diarrhea.

 

Types of Magnesium

Magnesium is essential for the functioning of our body and good health. Magnesium cannot be absorbed into the body without it first being attached to another substance that can transport it. Here are 7 types of magnesium available.

1. Magnesium Amino Acid Chelate

This is the tablet of a mineral chelate form of magnesium that contains an ion of magnesium oxide with a mixture of another form of amino acid.  This could be a lactate, a glycine, aspartate or arginate but the best form is aspartate or arginate.

2. Magnesium Oxide

This is commonly used as a laxative and for the relief of acid reflux. It is also known as “Magnesia”. Maybe you have heard of “Milk of Magnesia”.

3. Magnesium Citrate

This form is also used as a laxative to induce bowel movements and is often used before procedures like a colonoscopy to clean out the colon to make it visible. It is also used for the prevention of kidney stones.

4. Magnesium Orotate

This is the most effective of magnesium because it is the easiest absorbed. It also can be used as a way to relieve constipation.

5. Magnesium Chloride

This form is made of chlorine and magnesium. It serves as a PH regulator and a cleans for the body by getting rid of the acidic build up in the kidneys. It is most commonly used to help with the manufacturing of paper, some types of cement, and fireproofing agents.

6. Magnesium Lactate

Magnesium lactate is most commonly used for treating digestive issues such as heartburn, indigestion, and upset stomach. It should not be taken by those with kidney disease or kidney related issues.

7. Magnesium Sulfate

Magnesium sulfate is commonly known as Epsom salt and is a mixture of sulfur, magnesium, and oxygen. It is used to prevent seizures in pregnant women who suffer from severe pre-eclampsia, eclampsia, or toxemia.

8. Magnesium Carbonate

Magnesium carbonate is commonly known as chalk. It is what is used as the drying agent for pitchers, gymnast, and rock climbers. It is also used in flooring, toothpaste, cosmetics, and fire extinguishing compositions.

  1. This is one of the best reads I have had today.
    I don’t like taking supplements so I changed my nutrition to cater to that. And I didn’t even know that I have been eating plenty of food that has magnesium. Like tofu and black beans and bananas.
    What would be some recipes for magnesium? Can you have too much magnesium rich food?

    1. Hi Charlotte,
      I am not qualified as a doctor but I do know that you can not eat too many magnesium-rich foods because our kidneys eliminate excess amounts of magnesium in our urine. Brown rice and black beans would be a nice dish you can make or some sauteed spinach. Since beans are rich in magnesium you could make a bean soup.

  2. Thanks for the great post on Magnesium! There’s a lot of valuable information here which I found very useful.
    I’ve taken magnesium tablets before exercise to stop my legs from cramping. I knew that bananas where a source of them too but had no idea there were so many other natural options!
    Thank you I will share this around:)

    1. Hi Jeremy,
      That is great taking magnesium before exercising. I would love to take it but can’t because of my IBS. I am glad you found the post useful. Thanks for sharing!

  3. Great post! We recently started taking a magnesium supplement, but I like seeing which foods we can eat that are high in magnesium as well!

    1. Hi Melissa,
      It is important to know which foods we need to eat and for which reasons. Thanks for the comment and I wish you the best!

  4. WOW, That was very comprehensive! I especially liked how you listed all the available sources as well as all the medical uses! I mean really, 3.5 ounces of dark chocolate a day and 100gm of Mg? I could do that 😉

    1. Hi Colleen,
      Thank you for taking the time to comment, I am glad you found the post useful.

  5. Hi

    Thank you so much, I have been looking for some other treatments for my insomnia, who knew it may be as simple as this! I can’t wait to ask my Dr how much to take until then I am going to be adding in more of the foods.

    1. Hi Shannon,
      Lately, I have noticed everything concerning our health tieing back to our diet. The food pyramid we learned about in school seems to be more important than we seem to realize. Thank you very much for your comment and I wish you the best!

  6. Changing my diet was the best thing I have ever done after finding out I wasn’t getting enough magnesium into my body, I was going to go down the supplement road but I thought I would give the diet thing out and I have never felt as good as I do now. Great article and thanks for showing me more foods that are high in magnesium.

    1. Hi Matthew,
      Changing our diet should always be the first step to better health. Supplements are great when we can’t eat the way we should but if you can get a diet high in magnesium then you are on the right track. Good for you!

  7. I have been told that I need more magnesium for the muscle cramps that I get continuously. I was wondering which type of supplement would be best for this? I am guessing it is the magnesium chelate. Any suggestions on what I can take? I take other supplements that have magnesium in them, along with potassium and calcium (both of which are supposed to help with muscle cramps), yet I still get very painful cramps at night. They keep me up and I would just like to get rid of them.

    1. Have you tried a magnesium oil with magnesium chloride? You can spray it on topically, that may be good for you. You may want to try a warm bath in Epsom salt before bed too since it soothes muscles. All forms of magnesium are good for the muscles and since you can’t overdose on magnesium I would try to make sure I get enough Mg in my diet if I were you. Hope that helps, thanks for the comment!
