Need More Magnesium? 10 Signs to Watch For

Symptoms of poor magnesium intake can include muscle cramps, facial tics, poor sleep, and chronic pain. It pays to ensure that you get adequate magnesium before signs of deficiency occur.

But how can you know whether you’re getting enough?

According to population studies of average magnesium intake, there’s a good chance that you’re not.

Less than 30% of U.S. adults consume the Recommended Daily Allowance (RDA) of magnesium. And nearly 20% get only half of the magnesium they need daily to remain healthy.

DO I GET ENOUGH MAGNESIUM?

One method of assessing your magnesium status is to simply contact your health care provider and request detailed magnesium testing. Yet magnesium assessment is typically done using blood serum testing, and these tests can be misleading. Only 1% of magnesium in the body is actually found in blood, and only .3% is found in blood serum, so clinical blood serum testing may not successfully identify magnesium deficiency.

What to do?

Fortunately, it’s possible to get a sense of where your intake may lie simply by asking yourself a few questions about your lifestyle, and watching for certain signs and signals of low magnesium levels.

Learn how to read your signs below, and find out what you can do to ensure magnesium balance and good health. If you answer yes to any of the following questions, you may be at risk for low magnesium intake.

1. Do you drink carbonated beverages on a regular basis?

Most dark colored sodas contain phosphates. These substances actually bind with magnesium inside the digestive tract, rendering it unavailable to the body. So even if you are eating a balanced diet, by drinking soda with your meals you are flushing magnesium out of your system.4 5 6

The average consumption of carbonated beverages today is more than ten times what it was in 1940.7This skyrocketing increase is responsible for both reduced magnesium and calcium availability in the body.8 9

2. Do you regularly eat pastries, cakes, desserts, candies or other sweet foods?

Refined sugar is not only a zero magnesium product but it also causes the body to excrete magnesium through the kidneys. The process of producing refined sugar from sugar cane removes molasses, stripping the magnesium content entirely.

And sugar does not simply serve to reduce magnesium levels. Sweet foods are known by nutritionists as “anti-nutrients”. Anti-nutrients like sweets are foods that replace whole nutritious foods in the diet, yet actually consume nutrients when digested, resulting in a net loss. Because all foods require vitamins and minerals to be consumed in order to power the process of digestion, it’s important to choose foods that “put back” vital nutrients, and then some.

The more sweet foods and processed baked goods you have in your diet, the more likely you are deficient in magnesium and other vital nutrients.

3. Do you experience a lot of stress in your life, or have you recently had a major medical procedure such as surgery?

Both physical and emotional stress can be a cause of magnesium deficiency.

Stress can be a cause of magnesium deficiency, and a lack of magnesium tends to magnify the stress reaction, worsening the problem. In studies, adrenaline and cortisol, byproducts of the “fight or flight” reaction associated with stress and anxiety, were associated with decreased magnesium.4

Because stressful conditions require more magnesium use by the body, all such conditions may lead to deficiency, including both psychological and physical forms of stress such as surgery, burns, and chronic disease.

4. Do you drink coffee, tea, or other caffeinated drinks daily?

Magnesium levels are controlled in the body in large part by the kidneys, which filter and excrete excess magnesium and other minerals. But caffeine causes the kidneys to release extra magnesium regardless of body status.

If you drink caffeinated beverages such as coffee, tea and soda regularly, your risk for magnesium deficiency is increased.

5. Do you take a diuretic, heart medication, asthma medication, birth control pills or estrogen replacement therapy?

The effects of certain drugs have been shown to reduce magnesium levels in the body by increasing magnesium loss through excretion by the kidneys.

For a complete list of the specific drugs which can affect magnesium levels, read our article, Causes of a Lack of Magnesium.

6. Do you drink more than seven alcoholic beverages per week?

The effect of alcohol on magnesium levels is similar to the effect of diuretics: it lowers magnesium available to the cells by increasing the excretion of magnesium by the kidneys. In studies, clinical magnesium deficiency was found in 30% of alcoholics.10

Increased alcohol intake also contributes to decreased efficiency of the digestive system, as well as Vitamin D deficiency, both of which can contribute to low magnesium levels.11

7. Do you take calcium supplements without magnesium or calcium supplements with magnesium in less than a 1:1 ratio?

Studies have shown that when magnesium intake is low, calcium supplementation may reduce magnesium absorption and retention.12 13 14 And, whereas calcium supplementation can have negative effects on magnesium levels, magnesium supplementation actually improves the body’s use of calcium.7

Though many reports suggest taking calcium to magnesium in a 2:1 ratio, this figure is largely arbitrary. The ideal ratio for any individual will vary depending on current conditions as well as risk factors for deficiency.

However, several researchers now support a 1:1 calcium to magnesium ratio for improved bone support and reduced risk of disease. This is due not only to the increased evidence pointing to widespread magnesium deficiency, but also concerns over the risk of arterial calcification when low magnesium stores are coupled with high calcium intake.

According to noted magnesium researcher Mildred Seelig:

The body tends to retain calcium when in a magnesium-deficient state. Extra calcium intake at such a time could cause an abnormal rise of calcium levels inside the cells, including the cells of the heart and blood vessels… Given the delicate balance necessary between calcium and magnesium in the cells, it is best to be sure magnesium is adequate if you are taking calcium supplements.”8

8. Do you experience any of the following:

Anxiety?

Times of hyperactivity?

Difficulty getting to sleep?

Difficulty staying asleep?

The above symptoms may be neurological signs of magnesium deficiency. Adequate magnesium is necessary for nerve conduction and is also associated with electrolyte imbalances that affect the nervous system. Low magnesium is also associated with personality changes and sometimes depression.

9. Do you experience any of the following:

Painful muscle spasms?

Muscle cramping?

Fibromyalgia?

Facial tics?

Eye twitches, or involuntary eye movements?

Neuromuscular symptoms such as these are among the classic signs of a potential magnesium deficit.

Without magnesium, our muscles would be in a constant state of contraction.

Magnesium is a required element of muscle relaxation, and without it our muscles would be in a constant state of contraction. Calcium, on the other hand, signals muscles to contract. As noted in the book The Magnesium Factor, the two minerals are “two sides of a physiological coin; they have actions that oppose one another, yet they function as a team.”8

Chvostek’s Sign and Trousseau’s Sign are both clinical tests for involuntary muscle movements, and both may indicate either calcium or magnesium deficiency, or both. In fact, magnesium deficiency may actually appear as calcium deficiency in testing, and one of the first recommendations upon receiving low calcium test results is magnesium supplementation.

10. Did you answer yes to any of the above questions and are also age 55 or older?

Older adults are particularly vulnerable to low magnesium status. It has been shown that aging, stress and disease all contribute to increasing magnesium needs, yet most older adults actually take in less magnesium from food sources than when they were younger.

In addition, magnesium metabolism may be less efficient as we grow older, as changes the GI tract and kidneys contribute to older adults absorbing less and retaining less magnesium.15

If you are above 55 and also showing lifestyle signs or symptoms related to low magnesium, it’s particularly important that you work to improve your magnesium intake. When body stores of magnesium run low, risks of overt hypomagnesaemia (magnesium deficiency) increase significantly.

HOW CAN YOU KNOW FOR CERTAIN IF YOU HAVE A DEFICIENCY?

Magnesium’s impact is so crucial and far reaching that symptoms of its absence reverberate throughout the body’s systems. This makes signs of its absence hard to pin down with absolute precision, even for cutting edge researchers.  Doctors Pilar Aranda and Elena Planells noted this difficulty in their report at the International Magnesium Symposium of 2007:

The clinical manifestations of magnesium deficiency are difficult to define because depletion of this cation is associated with considerable abnormalities in the metabolism of many elements and enzymes. If prolonged, insufficient magnesium intake may be responsible for symptoms attributed to other causes, or whose causes are unknown.”

Among researchers, magnesium deficiency is known as the silent epidemic of our times, and it is widely acknowledged that definitive testing for deficiency remains elusive. Judy Driskell, Professor, Nutrition and Health Sciences at the University of Nebraska, refers to this “invisible deficiency” as chronic latent magnesium deficiency, and explains:

Normal serum and plasma magnesium concentrations have been found in individuals with low magnesium in [red blood cells] and tissues. Yet efforts to find an indicator of subclinical magnesium status have not yielded a cost-effective one that has been well validated.”16

Yet while the identification of magnesium deficiency may be unclear, its importance is undeniable.

Magnesium activates over 300 enzyme reactions in the body, translating to thousands of biochemical reactions happening on a constant basis daily. Magnesium is crucial to nerve transmission, muscle contraction, blood coagulation, energy production, nutrient metabolism and bone and cell formation.

Considering these varied and all-encompassing effects, not to mention the cascading effect magnesium levels have on other important minerals such as calcium and potassium, one thing is clear – long term low magnesium intake is something to be avoided.

WHAT CAN YOU DO TO INCREASE MAGNESIUM INTAKE?

The Magnesium Miracle, by Carolyn Dean, M.D. N.D.

The longer your intake remains low, the more likelihood your bodily stores will be diminished, leaving you exposed to some of the more troubling side effects of long term deficiency. According to Dr. Carolyn Dean, M.D., N.D., and expert on magnesium therapy, adequate magnesium can improve heart health, prevent stroke and obesity, and improve mood and memory.

If you answered no to all of the above questions, you may be able to rely on high food sources of magnesium, like those described in our article onMagnesium in the Diet.

Yet for many people, especially those with diseases and symptoms associated with low magnesium, active magnesium supplementation may be a crucial element of returning to good health.

In her book, The Magnesium Miracle, Dr. Dean notes that achieving adequate magnesium through foods is notoriously difficult, stating:

I’m convinced that to get enough magnesium today, you need to take supplements.”4

Transdermal magnesium does not have the side effects of oral supplements.

One of the most effective ways to improve your magnesium levels is to combine a healthy diet with transdermal magnesium.

Many of the factors which contribute to low magnesiumstores are caused by inefficiencies of the GI tract. By delivering magnesium through the skin directly to the cells,topical magnesium products bypass many of the problems associated with low magnesium absorption.

In older adults, reduced gastric acid levels in the digestive system may be a factor in reduced mineral availability. Hydrochloric acid supplements may be combined with magnesium to combat this dilemma; however a simpler and less expensive option is the use of magnesium chloride supplements. Magnesium chloride has been proven to have a high bioavailability, while simultaneously providing the chloride necessary for healthy digestion and vitamin and mineral absorption.

Magnesium researcher Mildred Seelig has called magnesium “the silent guardian of our hearts and arteries” and “necessary for life”. And Dr. Carolyn Dean calls it “the missing link to total health”.

If you haven’t heard much about magnesium and its importance to good health, now is the time to learn. And if it’s something you’ve always meant to look into, now is the time to take action!

Absorption maybe an issue, but assimilation into tissues is erratic 

Just an idea. Perhaps complexation with EDTA, cyclodextrines or PVP improve magnesium absorption. Some magnesium salts are better absorbed than others: chloride, nitrates, etc.

Dear Mr Luis,

Thanks for your reply. I thought about EDTA but it has the capability to complex with heavy metals to eliminate from the body, being which it also have the capability to form complex with Calcium. So I have a doubt about this. I tried to search article regarding this online but nothing convincing I got for using EDTA for absorption of Magnesium. 

Regarding Cyclodextrins I tried to search over online but I cannot find anything about its use with magnesium. 

Anyway I will check for the possibility for incorporating your input in my research and check with my results. 

Thanks once again. 

Prebiotics help absorption of Magnesium. Also Iodine and Calcium. 

Also organic salts are better absorbed.

Good Luck !

Ya, it seems to be interesting. Thanks for your input.

I will check for the same in my practical work.

Try Magnesium Aspartate or Magnesium Gluconate. Both are well absorbed.

Found that clinically - with follow up using blood values - Magnesium glycinate seems to be the best absorbed if the aim of the supplementation is a target blood level.  Have tried Mg Citrate, Mg Glucoheptonate and combinations of salt forms but Magnesium glycinate to date is the best with the least side effect.   Mg Citrate is a good salt form but its also a great laxative.
