Magnesium Deficiency, 10 Signs Of Magnesium Deficiency10 Signs Of Magnesium Deficiency

Magnesium is one of the most abundant minerals in the human body and is used in over 300 different physiological processes. Unfortunately, magnesium is also one of the most pervasive deficiencies in our society today. Could the lack of magnesium be influencing your health negatively? This article breaks down the signs of a magnesium deficiency and the best ways to get more in your diet.

According to American neurosurgeon Norman Shealy, MD, PhD, almost every known disease is associated with a magnesium deficiency. This may sound like a bold statement at first but it actually makes a lot of sense considering the number of roles it plays in the body. This also explains why there are such a diverse set of symptoms that occur when you are not getting enough of it.

There are 10 major signs that clue me in as to whether or not someone has a magnesium deficiency.

Magnesium Deficiency, 10 Signs Of Magnesium Deficiency

1. Poor Cognitive Processing 

If you are dealing with frequent bouts of brain fog, poor concentration, or constant memory issues, you may have a magnesium deficiency. Structures within every cell of the body, called mitochondria, are responsible for producing the energy that the body uses for everything.

The brain contains the highest concentration of mitochondria in the male body (females have a higher concentration in their ovaries). Mitochondria are heavily reliant on magnesium for energy production so a deficiency can hamper your brain performance significantly (1). It comes at no surprise that supplemental magnesium has been shown to improve learning and memory (2)!

2. Headaches & Chronic Migraines 

It has been found that sufferers of chronic migraines often have lower levels of magnesium in their bodies. Considering how important magnesium is for proper nerve function, this makes a lot of sense. Magnesium also plays the additional key role of regulating neurotransmitter production, which can also influence migraines.

Supplemental magnesium taken on a regular basis has been shown to decrease both the frequency and intensity of migraine headaches (3). Additionally, magnesium has been shown to have the same effect on non-migraine headaches as well.

Much of this has to do with magnesium’s ability to help regulate calcium balance within neuronal cells.  Too much calcium can lead to exitotoxic effects where the brain cells are overstimulated and this is a major factor in headaches and migraine formation.

3. Constipation & IBS 

Constipation is one digestive issue I hear all the time. Proper magnesium intake actually softens stools by drawing water into the bowels, supporting healthy elimination. If stools become too hard, they move slower through the colon and become a problem. This is why I always recommend magnesium when I hear this complaint.

For reference, an ideal stool should resemble type 3 or 4 on the Bristol stool chart below.

Additionally, magnesium plays a major role in regulating muscle contractions in the intestines and this is why a magnesium deficiency often results in constipation.  In this way, magnesium can also be a very helpful in relieving discomfort and cramping due to IBS or other similar conditions.

4. Fatigue 

Magnesium is highly involved with energy production. As mentioned before, the mitochondria in your cells heavily rely on magnesium to produce energy (4). Your mitochondrial function primarily determines your energy levels. Additionally, magnesium supports the adrenal glands which can play a huge part in energy production as well.

And the kicker… because magnesium is involved in so many enzymatic processes in the body, deficiency will make it harder to perform over 300 normal processes. This acts as a chronic stressor on your body and drains your energy!

If you are chronically fatigued, you may have a magnesium deficiency and increasing your magnesium intake can improve your energy levels drastically.

Magnesium Deficiency, 10 Signs Of Magnesium Deficiency

5. Insomnia 

Insomnia is one of the big conditions I see a lot of improvement in when beginning magnesium supplementation. This is because magnesium is involved in the production of GABA in the brain. GABA is what is known as an inhibitory neurotransmitter. This just means a chemical that promotes relaxation.

If you don’t have enough magnesium to produce adequate amounts of GABA, your sleep will likely suffer. Although there are other nutrients involved with GABA production, magnesium is a critical factor that will heavily determine your sleep quality.

6. Muscle Spasms & Cramping 

Because magnesium is so important for proper nerve transmission, it comes as no surprise that it also plays a vital role in muscle contraction. When magnesium is depleted, muscle contractions can become weak and uncoordinated, leading to involuntary spasms and painful cramps.

This is actually one of the most common early signs of magnesium deficiency. Spasms typically occur in the legs, feet, and sometimes even in places like the eyelids. If you are a woman, you may also experience worsened PMS-related cramping when magnesium stores are low.

7. Chronic Pain & Fibromyalgia 

Chronic pain and related conditions like fibromyalgia are heavily related to tension carried in the body. This tension can be purely physical, but can also be aggravated by emotional stress as well. Emotions such as anxiety, anger, and worry all contribute to physical tension. Over time this chronic tension leads to pain.

When magnesium stores are low in the body, the nervous system can become hyper excitable (meaning easily overstimulated) which can increase muscle tension. Magnesium can play a role here by helping to elicit an overall calming effect on the mind and body while soothing and relaxing the muscles.

8. Heart Arrhythmia

The heart is a muscle that constantly contracts inside our bodies without needing to be consciously controlled. Just as with other muscles in the body, the heart relies heavily on magnesium for proper contractility. This is thought to be due to its role in regulating calcium and potassium concentrations in the muscle tissue (5).

If you notice that your heart beats irregularly, magnesium may be something to address. This includes rapid heartbeats, slow heartbeats, and sudden changes in heart rhythm for no apparent reason.

9. Numbness and Tingling

If you often feel numbness or tingling sensations in your body, such as in the hands and feet, this is likely due to a change in nerve activity. For example, peripheral neuropathy (a common side effect of diabetes) is characterized by these sensations.

Because of its role in healthy nerve transmission, magnesium deficiency may be at least in part playing a role here. Limited research has been performed on this mechanism specifically, but some studies have shown that magnesium may be able to relieve or prevent numbness and tingling in the extremities.

This effect has been highlighted in research showing protective properties against peripheral neuropathy induced by certain cancer therapies (6).

10. Mood Disorders 

Magnesium plays a crucial role in regulating neurotransmitter balance. Neurotransmitters are chemicals in the brain that regulate thought patterns and behaviors ranging from motivation to sleep to focus (and many more). As mentioned before, magnesium is particularly involved in GABA production in the brain, which is a calming neurotransmitter.

A poor ability to produce adequate GABA in the brain results in conditions such as ADD/ADHD, anxiety, irritability, and general mood imbalances. If you identify with these feelings on a regular basis, you should consider increasing your daily magnesium intake.

3 Ways To Support Magnesium Levels 

Now that you know the signs of magnesium deficiency and just how important this mineral is for the human body, it is important to understand the best ways to obtain it. Follow these 3 strategies to boost your magnesium levels and do your health a tremendous favor.

Magnesium Deficiency, 10 Signs Of Magnesium Deficiency

1. Magnesium Rich Foods 

As with most nutrients, I always recommend starting with your diet. There are plenty of great food sources of magnesium that are easy to incorporate into your daily life. Some of my favorites are avocados, leafy green vegetables, and raw chocolate.

I’d recommend picking a few high-magnesium foods and consuming them on a regular basis. For example, I use avocados to make avocado chocolate protein pudding that I eat for lunch just about every day!

I have plenty more healthy recipes that feature magnesium-rich foods such as:

Chocolate Avocado Dessert Bars

Coconut Lime Seared Salmon

Super Sprout Chicken Salad

Pick your favorites from the list below and come up with creative ways to get them in your diet every day!

Magnesium Deficiency, 10 Signs Of Magnesium Deficiency

2. Epsom Salt Baths 

Perhaps one of the most relaxing ways to get more magnesium into your body is by taking an Epsom salt bath. Epsom salts are actually a form of magnesium that can absorb into the body through the skin while you soak. This is part of the reason why Epsom salt baths are so relaxing!

While traditional Epsom salts are made of magnesium sulfate, there are also newer forms of magnesium flakes that are made of magnesium chloride. Both types of salts provide benefits for the body, however magnesium chloride may be able to provide longer lasting benefits. This is because magnesium chloride is both easier to absorb and slower to be excreted from the body.

This means that less magnesium chloride is needed to derive benefits. One of my favorite brands of magnesium flakes is Ancient Minerals and their bath soak can be found here.

3. Supplemental Magnesium 

When it comes down to it, our food supply just isn’t what it used to be. Industrialization and poor attention to soil quality has depleted our soil of vital nutrients that used to be passed into the food we ate. Although we are starting to wake up to this fact and make more conscious efforts to create nourished farming conditions, our food is still lacking in the nutrition our bodies need.

This is why I recommend supplemental magnesium to so many of my patients. It is just so critically important to make sure you get enough magnesium in your diet that even I supplement with it every day. My two favorite forms of magnesium are either a high quality transdermal magnesium or powdered form.

Transdermal magnesium comes in a lotion that can be applied to the abdomen or areas of pain for quick absorption that bypasses the digestive tract. This is important especially in cases where the digestive tract is damaged or compromised and cannot absorb magnesium properly (such as leaky gut). My favorite transdermal magnesium can be found here.

In terms of powdered magnesium, I formulated my own product because I found it hard to come across a truly potent and therapeutic magnesium. I typically recommend my Brain Calm Magnesium because it contains a blend of magnesium forms including magnesium L-threonate. The L-threonate form of magnesium is the only form of magnesium proven to cross the blood-brain barrier and provide greater neurological benefits.

Final Thoughts 

By now you understand how important magnesium is for the human body. Even if you do not have any of the common symptoms of magnesium deficiency listed above, just about anyone can benefit from additional magnesium in the diet.

I use magnesium every day as I find that it helps keep my mind at ease and my energy levels balanced. It also has the cool effect of acting as an adaptogen by improving your body’s ability to adapt to everyday stressors. It truly is a modern-day health tonic!

  1. Outstanding information and outstanding presentation!

    BUT ! !

    Why don’t you please make it available in PDF [Portable Document Format] ? ?

    I have an app (Calibre) in which I can save PDFs (but not HTMLs) for rapid access and reading.

    I beg you, please easily convert to PDF and add that to your inventory of available info.

    1. There are several programs for printing web page into
      a .pdf file. I use PDFreDirect (Free Program) worked
      very well for me to keep a quick reference of this article.

    1. Hey Pascual, L-threonate is ingested orally and is able to cross into the brain. The magnesium oil is applied to the skin and absorbed into the blood but may not get into the brain as much.

  2. to Lynn Ferris – Seaholm High School,
    Hi Lynn, Unfortunately, I do not have a FB acct, thus I couldn’t answer you directly above as a “reply”, but the Keto eating plan is for everyone’s benefit, not just for Cancer patients. It helps to remove fat from around your organs, helps stabilize your blood sugar and insulin resistance, improve memory fog, assist with turning your body into burning the fat, and helps with a myriad of other potential issues and ailments. I have been doing it for 2 months and feel remarkably better, have lost some weight (YIPPEE) and find many other things better about my health including cholesterol count (LDL) being down.

    I hope that you will consider doing the Keto diet. I do it in moderation, meaning that I do not presently use a Chronometer APP to count my carbs, protein, fats, etc, but do use some Ketone test urine strips to validate that I am in Ketosis state, even if not at the highest level, which is where a Cancer patient needs to be in for remission to occur.

    1. Alma: I’m glad that I found your answer here about the ketogenic diet and what it is good for. It has cleared everything up for me and why I would want to get my diet changed over.
      I had no idea that it was good for removing the deep fat around our organs and helps to stabilize our blood sugar.
      I cannot wait to get started now; I need a great way to help me get started, step by step. Any ideas? Thanks.

  3. Thank you Dr. Jockers for this information about magnesium but i just want to know is there any test at all in order to find out if we have magnesium deficiency?

  4. Question about supplements in the blood vs the cells. Had a SpectraCell test done recently. Even though my regular labs (blood) show a normal level of Vit D, The SpectraCell test showed that most of the supplements I am taking are not getting into the cells. How does that work?

    How can supplements look ok on regular lab tests but the cells are starving? I take A LOT of supplements. All that money spent…sigh.

    1. Marita, You may find useful info at the website Coffee with Dr Stewart and listen to the talk on autophagy. Genetically, some have decreased cell cleaning, which can lead to this type situation.

  5. can we overdose on Magnesium?
    I am now on Keto and my cramps and spasming has got a lot worse. I understand this may be due to low potassium but find it very hard to get enough potassium into my reduced food intake (intermittent fasting) when a lot of fat reduces the amount of food each (2) meal. I feel like increasing the magnesium capsules but haven’t enough knowledge.

    1. The most common sign that you are taking too much magnesium is loose stools so that will be how you know you are taking too much. Be sure to also consume 1-2 teaspoons of a high quality salt each day. You can add to water or on food. Drinking plenty of water with some salt during the IF period can be very helpful! I like Celtic Gray Sea salt as it has a good mineral profile.

  6. Good afternoon,
    Because I’m having a problem swallowing the capsules now at my age(86) but oh so young at heart ) I’m needing to know when I break them into my health drink each day am I loosing some of the strength of the suppliment ? I would so like an answer to this issue.

    AS of now I do not use your suppliments because I just started getting your web sight and am so amazed.But I see some already I’m going to order. I’ve been using Andrew Lessmans Pro Caps..he has his own factory and has been doing this since his teens.Perhaps you have heard of him. Top of the line products. He is in Henderson, Nevada.
    Wit to hear from you. have a Blessed day…Shirley

  7. Whenever I take supplemental magnesium it seems to have the opposite effect on me. It actually causes leg muscle cramping at night. My lab magnesium is normal. Why do you think it would actually cause muscle cramping?

    1. Hi,

      This can be caused by an imbalance of magnesium to calcium. Most people are consuming enough calcium to balance their magnesium, but in the case a person is not, supplementing magnesium can cause calcium deficiency symptoms. They work together. Excess magnesium to calcium can also cause insomnia. It’s all about balance.

  8. Thank you Dr. Jockers for another amazing article, getting this much needed information out to people. You’ve helped me help my patients (and myself) in many ways, thank you!

  9. Great article. Although I should mention there was a recent 2017 study (linked below) that actually examined the effiacy of transdermal magnesium and it seems to point to the conclusion that it isn’t really isn’t absorbed that much. I remember reading about magnesium oil a while ago and rushed out and bought two 8lb bags of magnesium chloride flakes to make my own, practically reeling in excitement from the possibility of supplementing my magnesium-poor diet through a daily foot bath, how simple! Turns out, it seems to have been marketing for an otherwise barely-effective product. Despite this, you’ll see countless anecdotes on Amazon extolling the benefits for everything from mood, to sleep and skin conditions. Placebo effect? I hate to be the type of person to discount personal anecdotes because they are vitally important imo, but it does cause me to tread more carefully. At the very least, if we’re going to be 100% science based, it’s probably better off getting your magnesium from oral supplements and diet since those methods are actually supported by science.

    — NOTABLE EXCERPTS from: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5579607/

    1. “The stratum corneum functions to form a water-repellent barrier to protect underlying tissue from infection, dehydration, chemicals and mechanical stress [9]. Overcoming this layer in significant quantities is only possible for lipophilic substances. In magnesium chloride solution, magnesium is present in ionized form and therefore not able to penetrate a lipophilic layer. In addition, the radius of the hydrated magnesium ion (86 pm) has been reported to be 400 times higher than its dehydrated form, leading to the assertion that it is almost impossible for magnesium ions to pass through biological membranes [2].”

    2. “In this two-week pilot study, transdermal delivery of 56 mg Mg/day (a low dose compared with commercial transdermal Mg2+ products available) showed a larger percentage change in both serum and urinary markers from pre to post intervention compared with subjects using the placebo cream. However, based on this data from the original abstract, Kass et al. only show a slight increase of serum magnesium via transdermal magnesium-containing cream.”

    3. “One of the first studies on transdermal magnesium absorption was published by the naturopathic doctor and founder of the American Holistic Medical Association Norman Shealy, M.D. Ph.D in 2000. He was an early advocate for the particular benefits of transdermal applications of magnesium [12]. Shealy argued that a magnesium deficiency can be compensated by transdermal application within 4 to 6 weeks, whereas an oral supplementation is effective only after 4 to 12 months. A full publication of this comparative study could not be found. Only an abstract for a conference was published not showing any additional data to substantiate this statement [7].”

  10. Magnesium helped me so much. I soaked in Epsom salts every evening when I was bedridden with Scleroderma. The topical magnesium oil took about two months to really work, but not having the
    numb fingers, debilitating headaches and knotted calves is heavenly. It seems I just happen to like
    all the foods that are high in magnesium so I drink coconut water with organic pineapple for some
    potassium. This is an important article; magnesium is a solution for many ailments. Thanks!

  11. Hello I listen to your podcast on my way to work and is very much interested! my mom has heart disease and is on coumidin so she is not able to eat a lot of foods that is good for her she is experiencing memory problems amongs many other things I think that she is lacking magnisium ! What would be the best form for her and where can I buy it

  12. Hi,
    Have been doing Intermittent fasting for about 4 months, my window is 20 hours before feeding. I do HIIT and weight training about 3 to 4 times a week twice a day. I started my weight loss at 215, and now I’m 169. For weight loss and medical reason, I have been juicing all my vegetable and with maybe 3 ounces of meat for protein per day. I will be doing this for 30 maybe 60 days, and I feel find. My question is, will this affect me build muscle and losing weight, while doing this kind of fast. I have been told that I have to lay off meat to get the most out of me health in regard to my medical condition. Can I lay-off protein while doing weight training for health too.

    1. Hey Freda, If you are doing resistance training and HIIT you will need more protein. Typically between 1 – 1.6 grams per kg of body weight. Meat is one of the best sources but you can also use eggs, nuts/seeds and a vegan protein powder such as our Super Digest Protein.

  13. Hello dr.
    My wife has developed bladder stones. We r on a plant base diet.
    Eating a lot of Brazil nuts and walnuts and a lot of asparagus. Etc.
    R we eating too much calcium that recreated this? Thx dr.

    1. vitamin k2 is responsible for placing the calcium where it belongs, a deficiency can cause all sorts of calcium problems.

  14. Hi Doctor. What are the doses you recommend for magnesium supplements? Is there a difference in the form of the supplement? (threonate glycinate malate oxide orotate chloride sulfate taurate).

  15. I don’t think it’s a case of deficiency as in deficient diet, but likely a case of increased need (various stresses of civilization). This is not really the same thing: some people’s symptoms don’t improve unless they start a program of taking huge amounts of Mg thru supplement and high-Mg foods – quantities that no one anywhere on this planet has ever consumed since the Fall of Man (or the Big Bang or Day One or whatever your beliefs are).
