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 1940.7 This 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.
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:
- 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?
- 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.
