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, I tried taking magnesium supplement capsules once, and became dizzy, faint and nauseous.
    I know it was from the magnesium because I tested it several times, with the same effect. I took the the recommended amount stated on the bottle.

    Do you maybe know why?

    I have been told that I am low in magnesium, but I do not dare to take magnesium supplements again because of what happens when I do.

        No, my blood pressure is normal. But I do have unstable bloodsugar levels. My bodyweight (BMI) is below (Normal).

      If you’re getting low bp from magnesium its because the magnesium is hanging around in the blood instead of going into the cells. It’s like diabetes of magnesium. Just as you can lack insulin to transport sugar into the cell and it builds up in the blood causing symptoms you can also not have the required “co factors ” to transport the magnesium into the cell. It will build up in the blood giving you acute hypermagnesia for a short time until your body can get it the hell out of you. You need b vitamins mainly thiamine to get the magnesium out of the blood and into the cell. You also need certain amino acids but most people are deficient in the b vitamins necessary to transport magnesium into the cell. If you can’t get it out of the blood it will build up and make you dizzy, faint, everything will slow down , etc etc. Take a complex like megafood from real food ( very high in thiamine ). Don’t take overboard supplements because you can only absorb small amounts of b vitamins so the rest will get pee’d out! The amino acid thing is probably not likely. Eat some raw saurkraut so replace the flora that will make your b vitamins, and take megafood aswell. Your comment is the exact situation I went through so I felt the urge to help you.

    I was suffering from chronic pain that had me bed ridden. MRI, Full body CT scan, ultra-sound, over 40 blood tests – doctors could find nothing. I couldn’t sit for more than 15 minutes, pain was so bad I was in tears. I couldn’t ride on trains, cars, or airplanes. I couldn’t do anything that required arm movement. I mostly laid in bed.

    I felt I was having muscle cramps in my back (thorasic region) and in my solar plexus. My primary care doctor disputed this, but I saw a chiropractor and PT with some improve after 6 months twice weekly. Then, by chance, I started using magnesium oil spray on the effected areas. Within a week, the muscles relaxed enough that I could again sit at work for 8 hours per day. Riding in a car is still painful at times, but much easier. I have used magnesium oil for 3 months now and am really able to manage the pain and often am pain free. I have noticed though (44 years old) that with age and hormonal imbalance that with the onset of my cycle each month, the pain worsens. Overall though, magnesium oil has vastly improved my quality of life.

    I’m not sure if you will be able to answer my question but here it goes. I started getting pain in my hands &feet ( like in my bones) and my blood test showed my magnesium was low. I was put on supplements and began to feel better for a couple weeks then I got worse. My dr kept increasing my doseage since my levels continued to drop. I’m now on 1200mg a day and my body isn’t absorbing it. The symptoms are getting worse and now I’m getting more symptoms. What can cause your body not to absorb it? I eat very healthy, I don’t drink and I’m only 31. Is there anything else I can do or take to help? I’m getting impatient with my dr trying to figure it out.

    What does a low grain diet have to do with low magnesium? I recently was told that have sensitivities to almost all grains and cut them out of my diet. After doing that my depression and anxiety increased. What is the correlation if any? My natural path says I have low magnesium. Why is this???????

  5. Vera Avatar

    I have these white spots on my face. I have had them for over two years. Some fade away. others stay and want go away. I have tried what the doctor gave me; creams and washes nothing seems to work. I have dark skin so they show up more.

    hey there! my name is Andy, I live in italy and i’ve recently gone vegan.
    I practice yoga once or twice daily and i have a varied diet that consists of mostly vegetables and fruit, along with several types of nuts, coconut and olive oil, tofu and other soy products a few time a week, few whole grains, etc. It’s a pretty varied diet and as supplement I take acidophilus, digestive enzhymes and ive just ordered some VitaX Astaxanthin 12 mg after reading your inspiring article on it. I couldnt get the hawaian stuff here in Italy! I also supplement with spirulina.
    I have been reading about magnesium and im wondering what to do!
    from most articles i read it seems like i wouldn’t need any supplements for it but perhaps you could give me some precious advice? 🙂

    Hi there

    I’ve been suffering with real low mood, depression, anxiety, nervousness and real bad irritability for almost 6 months now. I’ve not been diagnosed with depression and anxiety, but I have suffered previously so I’m pretty sure of the symptoms. Either way, I felt awful, every day, consistently, not just a temporary case of the blues.
    So I went on St Johns Wort twice a day every day and it only seemed to take the edge off.
    Although it did make a difference, it wasn’t enough for me.
    So I went to the health/herbal shop and asked for some Valarium, because I couldn’t sleep. The advisor suggested I try Magnesium supplements. She said Magnesium is great for promoting natural sleep as it calms the muscles and nervous system.
    I thought I’d give it a try. I was only expecting it to help with sleep, however since I’ve been taking it (2 weeks now), I haven’t felt depressed in over a week. I just feel in a more positive mood now.
    Who knows if it’s the Magnesium but its the only supplement I’ve started taking recently.

    Here’s my background/details in case this information helps anyone. 🙂

    St Johns Wort – Brand – Natures Way – 0.3% which is 300mg, twice a day – been taking for 2 and a half months
    Magnesium – Brand – GO Healthy NZ – GO Magnesium 800 – 1 a day as advised on bottle – 360mg total elemental Magnesium (includes Mag aspartate, Mag amino acid chelate, Mag citrate and Mag oxide).
    I also take Vit B 100 Complex – Brand – Radiance – 1 a day but I quite regularly forget to take it 🙁
    I am not on any other medication, including not being on any contraceptive. I eat a gluten free, mostly Paleo diet and I also include a lot of coconut oil, chia seeds and nettle and red bush tea in my diet. Any of these could have an effect but I’m fairly sure the Magnesium is what has made the difference.

    Thanks and good luck everyone.

    Hi Wellness Mama – I love your site and all the information that you post. Quick question for you on the magnesium lotion (by Ancient Minerals – ordered from Radiant Life). First off, I apologize if this has already been commented on…but, I JUST started using this lotion, and I think I may have used too much. I have a few red “hives” – very itchy, “angry” spots on my body since using the lotion. Do you know if this is common in the beginning?

    Do I need to wait until those spots go away to resume using the lotion? Or should I just do a very little amount, and work my way up?

    Also, I have seen conflicting information about how much to take…I’ve seen at least 300mg per day (I’m female/mid-thirties), then I’ve also seen multiplying your weight (in lbs) by 3 or 4 to figure out the amount of mg needed per day. What advice do you follow?

    Thanks so much!

      1. Emily Avatar

        Thanks! Can you possibly help with determining how much to take daily? Do I count my dietary sources of magnesium (spinach, pumpkin seeds, etc.) towards that daily allotment?

        I just wondered how much you recommend, as I’ve seen/read some conflicting info on some other sites.

        Thanks again!

    I have taken oral magnesium in the past and everytime, I’d either have immediate heart palpitations (a bit painful) that made me think I was having a heart attack or I would get severely dehydrated if it was oxygenated magnesium (oxycleanse). Would the chest pain be an allergy or just a detox reaction? My body is a mess right now so I’m not sure what it could be. I’m just really scared to try transdermal magnesium supplementation since it goes directly to the bloodstream.

    Katie, I’ve been doing the liquid magnesium, 5 drops and the spray oil for the last couple of weeks and have noticed a significant muscle tension/Charlie horses soon after I started the mineral. I heard muscle cramps are a sign of low calcium, I take 500mg daily, so do you think I need to up my dosage to balance the magnesium intake? Or is this a sign of something else? Please reply with thoughts. Thanks!

    Several commenters have asked but I don’t see an answer. Just wondering if your aware that this article doesn’t tell you how to make your own magnesium oil, even tho it says that in the header. Maybe just remove that?

    Hi there, I enjoy your articles, writing style and choice of topics, I’m wondering, though–I can’t help it–what qualifications you have to give health advice? Your articles are not footnoted so from where do you get your information, google, bing? What is your education level. I like to know from whom I might be taking advice and if that advice is sound and well-founded. Thanks you so much, keep up the good mission!

    I discovered a suggestion for taking Magnesium for migraines when I began suffering from them every 2-3 days (previously I have had them since age 5 on and off and usually about every 3 months as an adult). I started with Natural Calm, and do still take that sometimes to help me sleep or aid in digestion, but it did nothing for my migraines. It chelated magnesium that prevents my migraines (everyone is different, I just wanted to share what worked for me). It also helped my cousin who was suffering from Raynaud’s syndrome. I would suggest it for anyone who also has cold hands and feet – I for one never have to wear socks to bed anymore! I did see in the comments that vitamin C works against it – I have read that it helps absorption https://www.wikihow.com/Best-Absorb-Magnesium-Supplements – although that link is not the source I originally found the info, I cant find my original source. Plus you recommend Natural Calm which is magnesium citrate – magnesium bound to citric acid. I have taken vitamin c with my magnesium and never felt a difference. I did however notice a difference when I started taking vitamin d this winter. I started to get small headaches every afternoon. Than I ran across this article – https://www.precisionnutrition.com/stop-vitamin-d. Now I don’t have a nutrition degree and this article went a little above my head, but I stopped taking the vitamin d and the headaches stopped.
    Just wanted to share my experience with magnesium – I think it is amazing!

    Wait… am I missing something? Wasn’t the title of this article “how to make your own Magnesium oil?”

    Hi! I was wondering if you dissolve magnesium in a carrier oil instead of water. I haven’t found anyone doing that so I figured there must be a reason. Any idea?

  17. Penny Avatar

    Magnesium, sodium, and potassium are supposed to exist together in a specific ratio. If you take magnesium that lowers sodium, and while most people overconsume sodium, some people do not use it at all. So for those people, supplementing magnesium will cause them to get low sodium, with all kinds of really nasty side effects like high pulse. Persons with low sodium will be unable to satisfy dehydration because all the water they drink will be urinated out in order for the body to prevent further dilution of already-too-low sodium.

    Wouldn’t it be better to find a proper balance between the critical electrolytes and supplement them together?

    Hello Everyone,

    I live in the UK and have so many of the above symptoms, I am constantly at my doctor and had such terrible pre-menstrual pains and swollen, painful breasts (that have not gone away since I started my period, yesterday) that I am at my wits end.

    I went to a family celebration yesterday and my male cousin – who is very health conscious and does a lot of research into health and vitality and has known of my weight gain, constant fatigue, etc etc but not of my sudden loss of my normally very sharp memory and concentration – that he mentioned that he felt that if I started taking magnesium supplements (because doctors in the UK tend to discount it in their medical appointments), he felt I would see a vast improvement.

    Of all the combination of the above symptoms I have been experiencing, also had chronic fatigue and sever headaches, severe leg cramps, severe pains in my joints and restless legs. The constant blood tests I have been having have have revealed vitamin D deficiency and I have been prescribed a mega-boost of Vitamin D 3 months (am in the second month of the supplement dose prescribed) and very low iron, so I am on 2 x daily iron). Symptoms decreased and as I said, I have had the worst PMS and menstruation since my late teen years, so I really, really hope this supplement of magnesium works.

    I am going to try the oil, first, as you suggest and I will mention this to my nurse when I go back for more blood tests, next Tuesday, as I would love to hear their opinion).

    I need to get back to work and start feeling and looking more like my fit, slim, energetic and very mind-alert self, as the last three years has seen such an increase in weight and lack of energy that I just feel like some sort of hypochondriac and need some sort of resolution or serious improvement in my condition so I can, well get back to ME.

    So glad I found this site and I have signed up to the newsletter. I will report back once I have started using the oil, to show my progress.

    Thank you and good luck to everyone on here in starting to feel better!

    Since I have 21 of the 26 issues listed, i promptly ordered myself a bottle of Magnesium Oil. it arrived yesterday and I am starting slow with 2 sprays twice a day and I’ll add another spray every day to build up to an appropriate level. if this helps, you will be my lifesaver Wellness Mama!!! Thank you for all of your information!
