The answer is likely “Yes” that you are deficient in Magnesium.

Magnesium is the eighth most abundant mineral on earth, and the third most abundant in sea water. More importantly, it is the fourth most abundant mineral in the human body and it is necessary in over 300 reactions within the body.

Magnesium isn’t just abundant in the body, but vitally important too. As this article explains:

Every single cell in the human body demands adequate magnesium to function, or it will perish. Strong bones and teeth, balanced hormones, a healthy nervous and cardiovascular system, well functioning detoxification pathways and much more depend upon cellular magnesium sufficiency. Soft tissue containing the highest concentrations of magnesium in the body include the brain and the heart—two organs that produce a large amount of electrical activity, and which can be especially vulnerable to magnesium insufficiency.

Proper magnesium ratios are important for the body to correctly use calcium in the cells. Even a small deficiency can lead to a dangerous calcium imbalance and lead to problems like calcification and cell death. This manifests itself with symptoms like heart trouble, migraine headaches, muscle cramps and premenstrual cramping.

Where Has All The Magnesium Gone?

Unfortunately, most modern farming processes tax the soil, depleting it of its natural magnesium. On top of that, many hybrids are selectively bred to survive low levels of magnesium and most conventional fertilizers use nitrogen, potassium, and phosphorus, and do nothing to replenish magnesium levels.

Water was once a good source of magnesium, but now:

Fluoride in drinking water binds with magnesium, creating a nearly insoluble mineral compound that ends up deposited in the bones, where its brittleness increases the risk of fractures. Water, in fact, could be an excellent source of magnesium—if it comes from deep wells that have magnesium at their source, or from mineral-rich glacial runoff. Urban sources of drinking water are usually from surface water, such as rivers and streams, which are low in magnesium. Even many bottled mineral waters are quite low in magnesium, or have a very high concentration of calcium, or both.

These additional dietary factors can also deplete magnesium:

  • Consumption of caffeine
  • Consumption of sugar (It takes 28 molecules of magnesium to metabolize a single glucose molecule! source)
  • Consumption of processed food
  • Consumption of alcohol
  • Consumption of produce from depleted soil
  • Consumption of foods high in phytic acid

Additionally, drugs like birth control pills, hypertension medicine, diuretics, insulin, and certain antibiotics (among others) deplete magnesium levels. Sweating often from exercise or other causes can also deplete magnesium.

What Does Magnesium Do?

Magnesium is necessary for hundreds of functions within the body, but is especially important for:

  • Gives rigidity AND flexibility to your bones (more important than Calcium in many cases)
  • Increases bioavailability of calcium
  • Regulates and normalizes blood pressure
  • Prevents and reverses kidney stone formation
  • Promotes restful sleep
  • Helps prevent congestive heart failure
  • Eases muscle cramps and spasms
  • Lowers serum cholesterol levels and triglycerides
  • Decreases insulin resistance
  • Can prevent atherosclerosis and stroke
  • End cluster and migraine headaches
  • Enhances circulation
  • Relieves fibromyalgia and chronic pain
  • Treats asthma and emphysema
  • Helps make proteins
  • Encourages proper elimination
  • Prevents osteoporosis
  • Proper Vitamin D absorption
  • protection from radiation
  • To aid weight loss
  • Lessen or remove ADD or ADHD in children
  • in proper digestion of carbohydrates
  • emerging evidence is showing a preventative role in many cancers
  • (source)

Even though magnesium deficiency is rarely addressed in medical settings, the National Institutes of Health website states that:

Some observational surveys have associated higher blood levels of magnesium with lower risk of coronary heart disease [50-51]. In addition, some dietary surveys have suggested that a higher magnesium intake may reduce the risk of having a stroke [52]. There is also evidence that low body stores of magnesium increase the risk of abnormal heart rhythms, which may increase the risk of complications after a heart attack [4]. These studies suggest that consuming recommended amounts of magnesium may be beneficial to the cardiovascular system.

Are You Low in Magnesium?

As I said above, the answer is likely ‘yes’ in today’s world, as over 80% of tested adults are. Unfortunately, blood tests are relatively ineffective in gauging magnesium levels as less than 1% of magnesium is in the blood.

Low magnesium levels are often diagnosed by symptoms alone, and the following symptoms can point to low magnesium levels:

  • Inability to sleep or insomnia
  • Irritability
  • Sensitivity to noise
  • Mental disturbances
  • Anxiety, depression or restlessness
  • Muscle soreness or spasms
  • Infertility or PMS
  • High levels of stress
  • Headaches
  • Heart “flutters” or palpitations
  • Fatigue or unusual tiredness
  • Coldness in extremities
  • Fuzzy brain or difficulty concentrating
  • Allergies and sensitivities
  • Lack of appetite
  • Back pain
  • Body odor
  • Bad short term memory
  • Poor coordination
  • Insulin resistance
  • Carbohydrate cravings
  • Constipation
  • Frequent cavities or poor dental health
  • Gut disorders
  • Kidney stones
  • Thyroid problems

If you have more than one of the above symptoms and especially if you have more than five, it is highly likely that you could benefit from magnesium supplementation.

How To Get Enough Magnesium

Unfortunately, magnesium is often not well absorbed by the digestive tract, and is even more difficult to absorb if you are deficient or are low in vitamin D, have poor gut bacteria or suffer from a number of other conditions.

On top of that, most foods are depleted of their natural magnesium levels and the water supply is lacking also. For this reason, I often use topical magnesium supplementation for our family.

There are several ways to supplement, and a mixture of more than one type of magnesium supplementation seems to be most effective. It is important to start slow and work up, as high doses will not be completely absorbed at first and most will be wasted.

Oral Magnesium Supplements

Leafy green vegetables, sea vegetables, kelp, and especially nettle are good dietary sources of magnesium, though if you have a deficiency, it will be difficult to raise your levels enough through diet alone. There is also evidence that over half of all magnesium taken internally is not used and leaves the body as waste. I take this timed release formula and B-vitamins and folate for better absorption. (I like it so much I reached out to them and they offered a 10% discount for Wellness Mama readers with the code wellness10.) Another great magnesium option is from BiOptimizers.

Transdermal Magnesium Supplements

Unlike internal doses of magnesium, topical magnesium does not have to pass through the digestive system and kidneys and can more quickly enter the blood and tissues of the body.

I now cycle a quality magnesium supplement like the one above with topical magnesium spray. I find topical to be the most effective (and cost effective!). You can make your own magnesium spray using this recipe or can try these hand-crafted jars of Magnesium Lotion as well.

Healthy Magnesium Levels: Bonus Benefit!

In fact, I was suffering from low vitamin D for years despite spending regular time in the sun and taking supplemental D3 at the suggestion of my doctor. Magnesium is needed for proper vitamin D absorption and it wasn’t until I increased my use of magnesium on my skin that my vitamin D levels finally went up.

If you’d like to learn more about the importance of magnesium and its various actions in the body, I’d suggest the book The Magnesium Miracle by Carolyn Dean as well as listen to my short podcast episode on magnesium.

    Hi Lenny !!!!

    I have read about a magnesium test that is superior to
    the run-of-the mill mag test. It is called simply the
    “Magnesium RB Test”. I don’t know anything about it,
    hope this helps………

    Hi,

    I just stumbled on your post and am glad that it’s here! My doctor recently ran blood work for my magnesium levels and she told me that my levels were “normal,” but I don’t feel like everything is normal, especially since I feel a number of the symptoms you listed. Is there a different test that would be more accurate? Thank you so much for your help.

      Hi Lenny !!!

      I’ve read, I believe on this blog, that there is a superior test to the run-of-the-mill mag test. It is called simply the “Magnesium RB Test”. I don’t know anything about it……
      Hope this helps. I wish you the best……..

    Hello, thank you for your article. I have most of the symptoms you listed. A friend gave me some Natural Calm to help me sleep better at night and energize me. I have been taking one half teaspoon for about a week now. To be truthful I feel horrible, but better (if that makes any since). My mind feels clearer and I am less constipated, but some days my back spazzes, my muscels ache, I feel fatigued, I have a headache, I have no appetite. Do I need to stop taking this, should I increase the amount, or should I continue as is? My husband is not overly supportive of me taking supplements. I am also nursing a two year old and an eight month old. I know I magnesium deficient because of all I have read, not just your article. Thank you for your time and input.

    My husband has severe lactose intolerance and IBS. He can’t seem to take any form of magnesium without it causing worse diarrhea. Will the oil work? What other suggestions do you have?

    I have a hormone imbalance. The only way i could get my period is if i take medroxyprogesterone. Would magnesium glycinate pills be able to replace the pills that my doctor gave me?

    Can’t find the answer anywhere, do you think it is safe to rub the mag oil on my one year old’s feet before bed?

    Hi, how many grams/milligrams of magnesium do you recommend for treating morning sickness through a homemade lotion, per day? I may use bath flakes or I might try the actual oil, but I’m wondering if you know how much to aim for. Thanks!!

    Hi Katie, 2 questions for you
    1. I live in pacific NW and its always raining, do i need to take calcium and vit D for the magnesium to work? (I bought the calm powder).
    2. Did you take this while you were nursing? Im pretty sure its safe but I want to mKe sure it wont affect my milk supply.
    I hope to get an answer from you. Im having almost all of those symptoms and my doc wants to put me on meds and i do not want to tKe anything.
    Thanks so much!

    I LOVE your blog! I’m just getting into the whole “DIY” scene and I’ve already made some amazing toothpaste based off of your recipes…so thank-you! Next stop is body lotion – and I’m low on magnesium too, so I thought I’d combine the two! Your blog is the first time I’ve heard of absorbing vitamins through the skin. My QUESTION is this: what type of magnesium do you have to use? Is there only one specific type that absorbs through the skin? I have “Trace Minerals Liquid Ionic Magnesium” already so I’m hoping I can use that. My mom also has some liquid magnesium spray she & I tried to help with pain, but it’s salty and incredibly itchy and never really soaks in. The links you provided for the transdermal method both lead to what looks like mineral salts for the bath…is this the only way to do it? Thank-you so much for your time & wonderful inventions!

    My husband has a major blood clotting factor, and can’t have much vitamin k in his diet, so will magnesium interfere with his problem?

    Hi Katie,
    I take armour for hashimoto. Is it safe to take a magnesium supplement? Does it interact with medication? Thank you so much for your great blog!!!

    Do you have any store bought magnesium oil or topical magnesium you can reccommend?

    Just wondering if anyone has had bad side effects from this. I made some the other day and found it very itchy on my hubby and my skin, to the point it felt like an allergic reaction. It did go away after a few minutes, but it was so intense I couldn’t imagine putting it all over my body. Also, I was awake all night. I had the worst sleep ever. All day today I’ve been in the washroom as well and feeling yucky.
    Is there a detox period maybe? I really want this to work as magnesium helps my hubby’s gout and I could use the benefits from it.

    the back of my nails turned grey so is the skin around my nails. They looked dirty like I’ve been gardening all day without gloves. I figure it’s either the magnesium oil or the vitamin C that I put on my face for wrinkles, which I apply with my fingers. I’m trying to keep nail polish on them but it help only partially, it’s very awful to look at that.
    That’s the only 2 things that I’m doing different then before.

    Did that happen to someone else. Any suggestion Wellness Mama?

    Other info to add to the post ….

    Due to a form of Nephrotic Syndrome (kidney disease), one medication that I take is Cyclosporine and it is notorious for depleting magnesium. Being an auto-immune disease, it is likely that my gut bacteria is out of normal range as well.

    I tried several forms of oral magnesium and was always pushing the limit of digestive distress and not totally relieving cramping and really odd memory issues … those seem to be tied most directly to the names of things and people. Very much in-the-moment, it is not like being intoxicated, and I can clearly visualize who or what I want, but the name is out of reach. I had one day where I could not recall my wife or son’s name. Another day I could not remember my employee number … it is only three digits and I have used it for 10 years.

    A topical Magnesium Gel really has been a tremendous help. It is applied to the back of the hands and tops of the feet. Being that your kidneys excrete the magnesium, I believe the application instructions intend to create the longest path back to them, so that cells along the way get what they need. I also have applied it to the back of my neck, with the thought that would put some closer to where my brain could use it. It works quite well.

    As an unexpected pleasant side benefit, I have a couple of toenails that have a moderate fungal infection, and this gel made it almost entirely go away … far better than any over-the-counter med and the topical med that my dermatologist prescribed.

    I switched to another brand of product this last time, and this is a Magnesium Oil Spray. I am not as happy with it. I don’t think it is as concentrated/effective, and will be switching back to what I used before. Both are available at the local health food store.

    To answer another poster’s question, this brand of oil claims to be “mined deep under the earth’s surface from the Zechstein Seabed in the Netherlands”. The gel claimed some other lakebed of some exotic European location as well.

    Hoping this info can help others, and wanted to add to your terrific website. I will be bookmarking it. Thanks!

      Hi Jeff,
      What is the brand of magnesium gel that you have used and found great results with?

      1. Dawn Avatar

        If he said ‘Zechstein Seabed in the Netherlands’ then I would suggest trying Life-Flo brand.

    Hi Katie, in regards to the spray made from flakes, would this be safe to spray on my children (ages 9,6 &4). Until we totally get our diet switched to one that is healthier I think this is something they could benefit from as well. Thanks in advance!

    Hi, my baby will be 6 months old tomorrow. I’m currently breastfeeding! 🙂 about 2-3 months ago I started getting tingling in my feet and hands, and pain in my arms and legs. And was extremely tired after multiple blood work. The last labs I had done a month and a half ago my dr’s office finally informed me this week, my iron saturation is pretty low. And my magnesium level is low. But my b12 is very high. Any ideas why? Also, they put me on a iron supplement 325mg a day. And magnesium oxide 800mg a day. After taking the iron I felt awful!!! And I’m scared to take the magnesium because of its side effects that I’ve read about. Is it safe to take. And is 800mg a normal dosage, for a supplement?

    Today I’ve sprayed for the first time, three sprays in my hand for each leg and rubbed it on my legs, but I have no tingly feeling at all, and it doesn’t leave a residue either, and now it worries me that I don’t have magnesium deficiency 😉
    Does it always tingle when you have a deficiency or could it not tingle also?

    I now rubbed it on my shoulder muscles (who’ve been so generous to give me daily pain for over a year) and that seems to itch and give me red spots (which strangely enough is more comforting than no reaction at all).

    1. chuck Avatar

      I’ve used Magnesium oil since May and really never felt the tingle or sting. But within the past few weeks, I have. I am not sure if the batch of Magnesium Oil (Ancient Minerals) is just stronger this time or if my skin is getting irritated from it. I usually only put about 8-10 sprays on at one time (100-125 mg) but I will usually hit a different body part each time throughout the day. At the end of the day I will have 700-900 mg of spray on my body. I don’t think if it stings or tingles is a very good indicator if you are deficient or not. I think other symptoms of Magnesium deficiency are a better indicator.

    How would I give Magnesium to a 9 year old boy with ADHD? The doctors are pushing to medicate him and I am against in every way, any advice on how I can get him to take Magnesium or how to give it to him would be so helpful.
