They call Magnesium the ‘Invisible Deficiency’ Affecting as many as 80% Of Americans. Magnesium is crucial to more than 300 bodily functions, including those affecting the heart, bones, muscles, and nervous system.
Magnesium deficiency is common in patients with diabetes, chronic fatigue syndrome, heart arrhythmias, mitral valve prolapse, heart attacks, and asthma.
Symptoms include:
- high blood pressure
- constipation,
- ADD (magnesium calms the nervous system),
- insomnia,
- restless leg syndrome and leg cramps,
- eye twitching,
- Raynaud’s Phenomenon,
- Migraines and menstrual cramps (magnesium is a muscle relaxer)
If you’ve recently had a blood test, you might assume it would show a magnesium deficiency. But only 1 percent of magnesium in your body is distributed in your blood, making a simple sample of magnesium from a serum magnesium blood test not very useful.
While diet is the No. 1 way to increase your magnesium levels, it is difficult. Our diets are high in processed foods instead of fresh veggies, grass fed meats, fruits, seeds and nuts. We drink RO water which is void of any minerals and even our organically grown vegetables are depleted because the water supply does not have it in it.
Getting your recommended daily intake of magnesium — 400 to 420 milligrams for men and 310 to 320 milligrams for women is tough unless supplementing.
Magnesium is not easily absorbed in the body unless first attached to transporting substance. For this reason, many supplement manufacturers have “chelated” magnesium to organic and amino acids. A few of these include magnesium oxide, magnesium sulfate and magnesium carbonate. Quality depends on the amount of magnesium in the supplement and how bioavailable it is. Bioavailability refers to the amount of magnesium in the supplement that can be assimilated by the digestive system and used for cellular activity and health benefit.
The Best Magnesium Supplement
Magnesium citrate — Magnesium citrate is the most popular magnesium supplement, probably because it is inexpensive and easily absorbed. Since citric acid is a mild laxative, magnesium citrate functions as a constipation aid as well as a magnesium source. It is a great choice for individuals with rectal or colon problems but is unsuitable for those with loose bowel movements.
Magnesium taurate — Magnesium taurate is the best choice of magnesium supplement for people with cardiovascular issues, since it is known to prevent arrhythmias and guard the heart from damage caused by heart attacks. Magnesium taurate is easily absorbed (magnesium and taurine stabilize cell membranes together), and it contains no laxative properties.
Magnesium malate — Magnesium malate is a fantastic choice for people suffering from fatigue, since malic acid — a natural fruit acid present in most cells in the body — is a vital component of enzymes that play a key role in ATP synthesis and energy production. Since the ionic bonds of magnesium and malic acid are easily broken, magnesium malate is also highly soluble.
Magnesium glycinate — Magnesium glycinate (magnesium bound with glycine, a non-essential amino acid) is one of the most bioavailable and absorbable forms of magnesium, and also the least likely to induce diarrhea. It is the safest option for correcting a long-term deficiency.
Magnesium chloride — Though magnesium chloride only contains around 12 percent elemental magnesium, it has an impressive absorption rate and is the best form of magnesium to take for detoxing the cells and tissues. Moreover, chloride (not to be confused with chlorine, the toxic gas) aids kidney function and can boost a sluggish metabolism.
Magnesium carbonate — Magnesium carbonate is another popular, bioavailable form of magnesium that actually turns into magnesium chloride when it mixes with the hydrochloric acid in our stomachs. It is a good choice for people suffering from indigestion and acid reflux, since it contains antacid properties.
Magnesium chloride can also be dissolved in water, forming what is known as magnesium oil (though not a true oil), and sprayed onto the skin using a pump action spray bottle, then rubbed in (focus on areas of pain or muscular tension). It is considerably cheaper to buy magnesium chloride flakes and make up a water based solution at home than it is to buy magnesium “oil” ready made. Home made magnesium oil applied in this way is the cheapest and fastest way to treat symptoms of magnesium deficiency.
The worst forms of magnesium
Magnesium oxide — Magnesium oxide is the most common form of magnesium sold in pharmacies, but it is non-chelated and possesses a poor absorption rate compared to those listed above.
Magnesium Stearate — Magnesium sulfate, also called Epsom salt, is a fantastic constipation aid but an unsafe source of dietary magnesium, since overdosing on it is easy.
The Role of Magnesium in Diabetes, Cancer, and More
Most people do not think about magnesium when they think about how to prevent chronic disease, but it plays an essential role. For instance, there have been several significant studies about magnesium’s role in keeping your metabolism running efficiently—specifically in terms of insulin sensitivity, glucose regulation, and protection from type 2 diabetes.
Higher magnesium intake reduces risk of impaired glucose and insulin metabolism and slows progression from pre-diabetes to diabetes in middle-aged Americans.5 Researchers stated, “Magnesium intake may be particularly beneficial in offsetting your risk of developing diabetes, if you are high risk.”
Multiple studies have also shown that higher magnesium intake is associated with a higher bone mineral density in both men and women,6 and research from Norway has even found an association between magnesium in drinking water and a lower risk of hip fractures.7
Magnesium may even help lower your risk of cancer, and a study published in the American Journal of Clinical Nutrition showed that higher intakes of dietary magnesium were associated with a lower risk of colorectal tumors.8
Results from the meta-analysis indicated that for every 100-mg increase in magnesium intake, the risk of colorectal tumor decreased by 13 percent, while the risk of colorectal cancer was lowered by 12 percent. The researchers noted magnesium’s anti-cancer effects may be related to its ability to reduce insulin resistance, which may positively affect the development of tumors.
Surprising Factors That Influence Your Magnesium Levels
Seaweed and green leafy vegetables like spinach and Swiss chard can be excellent sources of magnesium, as are some beans, nuts, and seeds, like pumpkin, sunflower, and sesame seeds. Avocados also contain magnesium.Juicing your vegetables is an excellent option to ensure you’re getting enough of them in your diet.
However, most foods grown today are deficient in magnesium and other minerals, so getting enough isn’t simply a matter of eating magnesium-rich foods (although this is important too). According to Dr. Dean:
“Magnesium is farmed out of the soil much more than calcium… A hundred years ago, we would get maybe 500 milligrams of magnesium in an ordinary diet. Now we’re lucky to get 200 milligrams.”
Herbicides, like glyphosate also act as chelators, effectively blocking the uptake and utilization of minerals in so many foods grown today. As a result, it can be quite difficult to find truly magnesium-rich foods. Cooking and processing further depletes magnesium.
Meanwhile, certain foods can actually influence your body’s absorption of magnesium. If you drink alcohol in excess, for instance, it may interfere with your body’s absorption of vitamin D, which in turn is helpful for magnesium absorption. If you eat a lot of sugar, this can also cause your body to excrete magnesium through your kidneys, “resulting in a net loss,” according to Dr. Danine Fruge, associate medical director at the Pritikin Longevity Center in Florida.9 The following factors are also associated with lower magnesium levels:10
- Excessive intake of soda or caffeine
- Menopause
- Older age (older adults are more likely to be magnesium deficient because absorption decreases with age and the elderly are more likely to take medications that can interfere with absorption)
- Certain medications, including diuretics, certain antibiotics (such as gentamicin and tobramycin), corticosteroids (prednisone or Deltasone), antacids, and insulin
- An unhealthy digestive system, which impairs your body’s ability to absorb magnesium (Crohn’s disease, leaky gut, etc.)
Calcium, Vitamin K2, and Vitamin D Must Be Balanced with Magnesium
It may seem like you could remedy the risks of low magnesium simply by taking a supplement, but it’s not quite that simple. When you’re taking magnesium, you need to consider calcium, vitamin D3 and vitamin K2 as well, since these all work synergistically with one another. Excessive amounts of calcium without the counterbalance of magnesium can lead to a heart attack and sudden death, for instance. Research on the Paleolithic or caveman diet has shown that the ratio of calcium to magnesium in the diet that our bodies evolved to eat is 1-to-1.11Americans in general tend to have a higher calcium-to-magnesium ratio in their diet, averaging about 3.5-to-1.
If you have too much calcium and not enough magnesium, your muscles will tend to go into spasm, and this has consequences for your heart in particular. “What happens is, the muscle and nerve function that magnesium is responsible for is diminished. If you don’t have enough magnesium, your muscles go into spasm. Calcium causes muscle to contract. If you had a balance, the muscles would do their thing. They’d relax, contract, and create their activity,” Dr. Dean explains.
When balancing calcium and magnesium, also keep in mind that vitamins K2 and D need to be considered. These four nutrients perform an intricate dance together, with one supporting the other. Lack of balance between these nutrients is one of the reasons why calcium supplements have become associated with increased risk of heart attacks and stroke, and why some people experience vitamin D toxicity. Part of the explanation for these adverse side effects is that vitamin K2 keeps calcium in its appropriate place. If you’re K2 deficient, added calcium can cause more problems than it solves, by accumulating in the wrong places, like your soft tissue.
Similarly, if you opt for oral vitamin D, you need to also consume it in your food or take supplemental vitamin K2 and more magnesium. Taking mega doses of vitamin D supplements without sufficient amounts of K2 and magnesium can lead to vitamin D toxicity and magnesium deficiency symptoms, which include inappropriate calcification that may damage your heart.
Tips for Increasing Your Magnesium Levels
One way to really increase your magnesium, as well as many other important plant-based nutrients, is by juicing your greens. I typically drink one pint to one quart of fresh green vegetable juice every day, and this is one of my primary sources of magnesium. Organic foods may have more magnesium if grown in nutrient-rich soils but it is very difficult to make that determination. If you opt for a supplement, be aware that there are a wide variety of magnesium supplements on the market, because magnesium must be bound to another substance. There’s simply no such thing as a 100 percent magnesium supplement.
The substance used in any given compound can affect the absorption and bio availability of the magnesium, and may provide slightly different, or targeted, health benefits. The table that follows summarizes some of the differences between the various forms. Magnesium threonate and citrate are some of the best sources, as it seems to penetrate cell membranes, including your mitochondria, which results in higher energy levels. Additionally, it also penetrates your blood-brain barrier and seems to do wonders to treat and prevent dementia and improve memory. If you take a supplement, you can use the “bowel test” to determine if you’re taking too much magnesium. Dr. Dean explains:12
“The best way to tell if you are getting enough magnesium is the “bowel test”. You know when you have too much magnesium when your stools become loose. This, in fact, may be a blessing for people with constipation… [which] is one of the many ways magnesium deficiency manifests.”
Besides taking a supplement, another way to improve your magnesium status is to take regular Epsom salt baths or foot baths. Epsom salt is a magnesium sulfate that can absorb into your body through your skin. Magnesium oil can also be used for topical application and absorption. Whatever supplement you choose, be sure to avoid any containing magnesium stearate, a common but potentially hazardous additive.
