Do you have any of these 12 magnesium deficiency symptoms?

You probably have no idea that you are currently suffering from magnesium deficiency. Indeed, studies show that up to 89% of Americans are magnesium deficient.  Read on to see if you have any of these 12 magnesium deficiency symptoms.

Jill’s Experience

Jill was a 45-year-old woman suffering from a heart condition known as atrial fibrillation. It made no sense why someone so young should develop this heart condition as she didn’t have any of the usual atrial fibrillation risk factors.

The only tip-off as to the cause of her atrial fibrillation was that she was taking Prilosec for acid reflux, Lasix occasionally for leg swelling, and she was eating the “Standard American Diet.” Even though her magnesium levels came back normal on her blood test, I suspected a magnesium deficiency as the cause of her heart problem.

Interestingly, once I convinced her to replace all added sugars and processed foods with real foods which included a massive salad every day, she immediately lost 20 pounds without even trying. In no time at all her acid reflux was gone and she was off the Prilosec. Also, with no added sugars or processed foods, her legs no longer swelled so there was no further need of diuretics.

Best of all, she felt better than she had ever felt and her atrial fibrillation went away. As she made many lifestyle changes, it was impossible to know what exactly drove her atrial fibrillation into remission.

However, in my mind, I’m sure replacing her magnesium stores played a role. Continue reading to figure out how she boosted her magnesium stores.

Can you test for magnesium deficiency?

While you can test for magnesium deficiency, you probably don’t want the test your doctor orders. The reason for this is because the standard magnesium test only measures the magnesium in your blood.

As 99% of your magnesium is not freely floating around in your blood but rather is inside of your cells and bones, you need a better test for magnesium deficiency. Of the various ways to test for magnesium deficiency, probably the best is the RBC magnesium test. The RBC magnesium test measures the amount of magnesium inside of your red blood cells.

Who is at risk for magnesium deficiency?

Many things contribute to magnesium deficiency. For example, if you are under a lot of stress, you likely are not absorbing much magnesium from your food.  Those who love drinking filtered or bottled water also aren’t getting much magnesium. And processed foods are notorious for being completely absent of magnesium.

Other conditions contributing to magnesium deficiency include being overweight, diabetic, or over age 60. Likewise, many prescription medications like diuretics or acid-blocking medications are also keeping your magnesium levels dangerously low.

Do you have any of these 12 magnesium deficiency symptoms?

1. Weight Gain/Diabetes

When you don’t get enough magnesium in your food and water, it can cause glucose and insulin levels to rise.  When insulin levels are high, you may suffer from food cravings.  Unfortunately, these food cravings are generally for sugar or processed carbohydrates which lead to further weight gain.

2. Fatigue and Muscle Weakness

Magnesium is a critical component of energy production in the body.  In fact, the body’s energy molecule, ATP, is created through magnesium dependent chemical reactions.

If you are tired all the time, you are probably magnesium deficient.  Likewise, if your muscles are weak, you may also not be getting enough magnesium.

3. Anxiety

People under high levels of mental or physical stress, poorly absorb magnesium from the gastrointestinal tract. Contributing to a downward spiral, magnesium deficiency is a significant cause of anxiety.  Fortunately, studies show that restoring the magnesium may help in the treatment of anxiety.

4. Insomnia

Having enough magnesium balances out your stress hormones.  Magnesium also helps the body maintain sufficient melatonin and other sleep hormones.  Indeed, magnesium supplementation has been shown to help with sleep.

5. Depression

Magnesium deficiency and depression go hand in hand.  Low magnesium stores lead to depression and people suffering from depression are more likely to eat a diet low in magnesium.

6. Dental Cavities or Osteoporosis

Dental cavities and osteoporosis are two more signs of magnesium deficiency.  Magnesium affects vitamin D metabolism and osteocalcin which play a vital role in bone turnover and formation.

Ironically, if you are taking calcium supplements for osteoporosis, you may be making matters worse. Calcium supplementation can throw off your calcium/magnesium balance.

7. Constipation

If you suffer from constipation you probably are magnesium deficient.  Magnesium in any form is an excellent laxative.

8. Muscle Cramps or Migraine Headaches

Do you suffer from leg cramps, eye twitches, or muscle spasms?  Do you get frequent headaches? These may all be magnesium deficiency symptoms.

9. Inflammation, Arthritis, or Autoimmune Diseases

If you suffer from chronic inflammatory conditions, such as arthritis or autoimmune diseases, you may be magnesium deficient.  Studies have linked magnesium deficiency to arthritis and elevated C-reactive protein (CRP) blood tests.

10. Palpitations, Heart Attacks, Heart Failure, or Cardiac Arrest

Most forms of heart disease are linked to magnesium deficiency.  This mineral is critical to optimal cardiac function.

11. Thyroid Problems

Thyroid problems are widespread in the U.S.  Research suggests that many thyroid issues may be due to magnesium deficiency.

12. Cancer

Cancer may be a wake-up call that magnesium levels are low. Magnesium is a critical nutrient for many DNA repair mechanisms.   As new cancer cells are created every day in your body, you need your DNA repair mechanism functioning optimally.

Magnesium in Our Water

Our ancestors used to get large amounts of magnesium just from their drinking water.  Mountain spring water is naturally high in magnesium.  Unfortunately, many municipalities remove magnesium as part of their water treatment process.

If you want to see how much magnesium is in your drinking water, click here.  In general, the “harder” your water, the more magnesium you are getting.

Interestingly, drinking hard water may lower your risk of heart disease.  If you happen to live in a city with naturally hard water, you can get up to 30% of the magnesium you need each day from water.

Unfortunately, water softeners, water filters, reverse osmosis devices, and bottled water are generally all depleted of magnesium.  If you drink any of these magnesium depleted water types, you have to get 100% of your magnesium from food.

Magnesium in Our Food

Once upon a time, our soil contained much more magnesium.  Unfortunately, modern agriculture has stripped this essential mineral from the ground.  Processed foods are even worse when it comes to magnesium content.

Fortunately, organically grown produce has been shown to have up to 29% more magnesium.  To get enough magnesium in your diet, make sure you eat plenty of green leafy vegetables, especially spinach, nuts, seeds, and legumes every day.  To see a breakdown of which foods contain the most magnesium click here.

Can you get too much magnesium?

In general, it is very tough to get too much magnesium from your food and water unless you have kidney disease.  Certainly, it is possible to get too much magnesium if you are taking supplements.

How much magnesium do you need each day?

The recommended daily amount of magnesium varies depending on your gender and age. Assuming there are no problems with magnesium absorption, you need about 400 mg of magnesium each day. If you can get at least 400 mg of magnesium daily from your water and food, you can start to enjoy the health benefits of magnesium.

Magnesium in China’s Longevity Village

As you know, we have been studying the residents of China’s Longevity Village for many years.  We have found that these people do not suffer from magnesium deficiency symptoms.

The mountain spring water they drink is extremely hard and packed full of essential minerals.  Researchers suggest that these people get up to 50% of their magnesium just from the water.

Also, modern agriculture has yet to put a stake in the ground in this rural area of China.  Thus, the soil is extremely high in magnesium and other minerals.

Their diet, which is very high in vegetables, nuts, seeds, and beans, only further augments the magnesium they are getting every day.  We suspect that the magnesium in their food and water may be a major reason why heart disease is very uncommon, and people live to old ages free of chronic medical conditions.

To learn more about why China’s Longevity Village has the highest known concentration of centenarians in the world, please be sure to pick up a copy of our new book, The Longevity Plan.

How can you correct magnesium deficiency?

Let me give you five simple steps to correct magnesium deficiency.

1. Drink hard or mineral water.

2. Eat a heaping salad with spinach, nuts, seeds, and legumes daily. 

3. Embrace the stress in your life.

4. Talk with your doctor about magnesium supplements.

5. Talk with your doctor about medications that may be contributing to your magnesium deficiency like diuretics, acid reducing medications, or calcium supplements.

Practical Tips

As 89% of Americans are magnesium deficient, there is a high likelihood that you may be one of them. Fortunately, magnesium deficiency is easy to correct.

I know I used to be one of these people. Before my health transformation, I required Prilosec daily for acid reflux, ate the Standard American Diet, and was always stressed. These three things alone probably put me also into a state of magnesium deficiency.

Now, in addition to eating a diet very high in magnesium, I have found that taking a magnesium supplement before bed helps me to sleep. Indeed, medical studies show that magnesium supplementation is an effective treatment for insomnia.

If you suspect you may have a magnesium deficiency as well, correct anything that can be fixed to boost your magnesium stores. Also, speak with your physician about whether a magnesium supplement might be right for you.

  1. Hi. My water is very hard, but I’ve also heard that it is full of unhealthy chemicals. What should I do? Thank you! I thoroughly enjoy each article. They are filled with up-to-the-minute information and is relevant. Thank you again!

    • Hi Jeri,

      Thanks for reading! Sounds like it is time to test your water. There are a number of do it yourself testing kits online or you could bring in a profession. Hopefully, you have high quality water in your home!

    • Hi PJ,

      For those who may not be aware, HTMA stands for Hair Tissue Mineral Analysis. This test looks at the minerals from a small sample of your hair. Not only can this assess for magnesium deficiency but it can also look at other mineral deficiencies or possibly heavy metal toxicity as well. Some feel this is a more accurate test than the Red Blood Cell magnesium test and definitely more accurate than the serum magnesium good level.

      Hope this helps!

  2. Dear Dr. Jay, Thanks for your informative articles.
    Since Magnesium deficiency is so high, and is a potential problem in one’s health, why aren’t physicians checking or warning patients about it. Should I be taking magnesium since I have the symptoms listed in this article?

    Thanks, Glen

    • Hi Glen,

      Thanks for reading and commenting! Great questions.

      The problem is that there is no good readily available test for magnesium. While it is easy to measure magnesium levels from a blood test, this test only checks for the magnesium in your blood. At most, 1% of your magnesium is in the blood. To really test for magnesium requires expensive tests that can only be done in a research setting.

      Whether or not you should take magnesium supplements is a discussion you need to have with your healthcare provider. There are risks and benefits to everything you take into your body. Fortunately, for most people, the risks of magnesium supplements are very low.

      Certainly, a diet high in greens, nuts, and seeds is a healthy diet. Greens, nuts, and seeds are all very high in magnesium.

      Hope this helps!

  4. Thanks for your newsletters! I always enjoy reading them. You may have addressed this question sometime in the past but I’m curious if you think getting a heap of greens by way of a green smoothie would be an adequate way to get magnesium as well or if blending the greens would affect how nutrients/minerals are absorbed. I try to eat salads when I can but find I am much more able to be consistent about getting in a smoothie (a blender filled with mostly spinach or other frozen greens, a few berries or other fruit, some combination of nuts/seeds, and water/ice). I’d love to know if you think that’s an okay option or if I should really push harder to eat those salads. Thanks again!

    • Hi Lisa,

      Your smoothies sound very healthy. While smoothies are a great way to get greens, often time there are not that many greens. If a daily salad is something that is challenging for you, look for other ways to greens, in addition to your smoothie.

      Thanks for reading and hope this helps!

  5. Dear Dr. Day,

    Thank you so much for an excellent article on Magnesium. I have been taking it as a supplement (1) 500mg tablet for years now as I had terrible cramps at night and this was to recommended to me by my endocrinologist. I have had a a rough time medically speaking for the last 2 years working in Nigeria and have just recently returned to Australia to live. There seems to be a problem with the amount of medication I have prescribed in Nigeria for an under active thyroid prolem. I have always taken 100ug but after a blood test my Endocrinologist increased it to 125ug. On arrival home in Australia my test showed it was 28 and immediately my GP explained I would have to take less but over time. I had the results of my latest blood test yesterday and although my T3 &T4 are good my TSH was 0.03? My doctor has stated it should not be this low but she gave me no explanation as to why it is so low. Previously to this around 6 weeks previously it was 0.09. I have no other medical conditions and I am eating lots of fresh fruit and vegetables since returning home. I am looking for work in my small home town but in the meantime I have volunteered for 3 local organisations to use my work abilities. I do not get out much except for these 3 times a week but I feel well but am interested in finding out why my TSH is so low? I will try your wife’s recipe this week and give you some feedback. Take care Catherine

  6. Dear Dr. Day,

    Ken & I were out walking in the sunshine with our dog when your newsletter came in on his new phone. We both smiled to know that your communication had arrived.

    The article about the town in PA (my home state) was interesting because earlier today I was thinking about the presence of family and good health. My earlier reflection was a resolve to get out there and join more groups for fun, learning, and fellowship. Your article was right on target for me as is the case so many times and I thank you.

    The Curry Lentil soup looks wonderful too! I will be making it sometime soon you can be sure! It is always nice to try new ideas in cooking the evening meal since we enjoy the Mediterranean & Asian type cuisines so very much. Thank you Jane.

    Have a wonderful day.

    Deby & Ken

    • Hi Deby and Ken,

      Thank you so much for reading the newsletter! I am so happy to hear that the suggestions had a positive impact. Yes, strong social ties are an often overlooked element of health.

      All the best,

      John

  7. Thank you for providing this information. I had a few losses recently both loved people and pets. The past few weeks been using low dose of lexapro and xanax. Will make sure magnesium is added to my other heart supplements.
    Loretta

    • Hi Laura,

      Thanks for reading! So sorry to hear about the losses. Make sure your physician is aware of everything you are taking through this grieving process.

      Wishing you the best,

      John

  8. Excellent Information!! Thank you! However, now I’m confused by reading about other supplement recommendations. Some say to obtain magnesium through transdermal delivery. Additionally, there are multiple different types of magnesium supplements oxide, sulfate, chloride formulations. Which is best? Which is absorbed better? Could you just take a teaspoon of epsom salts a day as the bag says there are 475 mg. in a teaspoon and be done with it?
    I’m falling into several categories of the symptoms, attributed it to perimenopause. I’ve ordered Twinlab TriBoron Plus to help supplement. I’d read/heard Boron assist in hormone regulation. Any thoughts you have would be appreciated.
