Today's post is brought to you today with the permission of Dr. Mercola. He has a ton of great information on magnesium on his site. The more I learn about magnesium, the more fascinated I become. I know that I am deficient in magnesium and will be working on incorporating more magnesium-rich foods into my diet, as well as supplementing as needed. I also use magnesium oil, which I wrote a detailed post on. I highly recommend checking that out. ~Jessica
Low Magnesium May Play Key Role in Insulin Resistance and Diabetes
By Dr. Mercola
Magnesium is the fourth most abundant mineral in your body. If you don't have enough of it, your body simply cannot function at its best. Insufficient cellular magnesium levels set the stage for deterioration of proper metabolic function that typically snowballs into more significant health problems.
As reported by GreenMedInfo,1 researchers have now detected 3,751 magnesium-binding sites on human proteins, reflecting how important this mineral is to a great many biological processes.
For example, magnesium plays a role in your body's detoxification processes and therefore is important for minimizing damage from environmental chemicals, heavy metals, and other toxins.
Even glutathione, considered by many to be your body's most powerful antioxidant, requires magnesium in order to be produced.
Magnesium also plays roles in preventing migraine headaches, cardiovascular disease (including high blood pressure, heart attacks, and strokes), sudden cardiac death, and even reduces death from all causes.
This important mineral is required by more than 300 different enzymes in your body, which play important roles in the following biochemical processes, many of which are crucial for proper metabolic function:
|Creation of ATP (adenosine triphosphate), the energy molecules of your body||Proper formation of bones and teeth||Relaxation of blood vessels|
|Action of your heart muscle||Promotion of proper bowel function||Regulation of blood sugar levels|
Low Magnesium Levels Consistently Found in Those with Elevated Insulin
In just the past year, there have been several significant studies about magnesium's role in keeping your metabolism running like a well-oiled clock—specifically in terms of insulin sensitivity, glucose regulation, and protection from type 2 diabetes. Here are just a few:
- One 2013 study involving pre-diabetics found that most had inadequate magnesium intake. Those with the highest magnesium intake reduced their risk for blood sugar and metabolic problems by a whopping 71 percent.2
- An ADA study from October 20133 found that higher magnesium intake reduces risk of impaired glucose and insulin metabolism and slows progression from pre-diabetes to diabetes in middle-aged Americans. Researchers stated, “Magnesium intake may be particularly beneficial in offsetting your risk of developing diabetes, if you are high risk.”
- In a large Japanese study (the Hisayama Study) published in Diabetic Medicine December 2013, researchers found magnesium intake was a significant protective factor against type 2 diabetes in the general Japanese population, especially among those “with insulin resistance, low-grade inflammation and a drinking habit.”4
- And in the Framingham Offspring cohort (2006), higher magnesium intake improved insulin sensitivity and reduced type 2 diabetes risk.5
Why Is Magnesium So Critical for Proper Metabolic Function?
The mechanism by which magnesium controls glucose and insulin homeostasis appears to involve two genes responsible for magnesium homeostasis.6Magnesium is also required to activate tyrosine kinase, an enzyme that functions as an “on” or “off” switch in many cellular functions and is required for the proper function of your insulin receptors.
It is well known that people with insulin resistance also experience increased excretion of magnesium in their urine, which further contributes to diminished magnesium levels. This magnesium loss appears to be secondary to increased urinary glucose, which increases urinary output.7
Therefore, inadequate magnesium intake seems to prompt a vicious cycle of low magnesium levels, elevated insulin and glucose levels, and excess magnesium excretion. In other words, the less magnesium your body has, the less it appears to be able to “hang onto it.8
Rarely do so many studies from around the world find universal agreement on a subject! The evidence is clear: if you want to optimize your metabolism and keep your risk for type 2 diabetes low, one of the things you need to do is consume adequate magnesium. Unfortunately, this is not the norm, as an estimated 80 percent of Americans are magnesium deficient.
Are Your Magnesium Levels Up to Par?
Dietary surveys suggest that the majority of Americans are simply not getting enough magnesium from their diets alone. Other factors that can make you more prone to magnesium deficiency include:
|An unhealthy digestive system:which impairs your body's ability to absorb magnesium (Crohn's disease, leaky gut, etc.)||Diabetes: especially if poorly controlled, leading to increased magnesium loss in urine||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|
|Unhealthy kidneys:which contribute to excessive loss of magnesium in the urine||Alcoholism: up to 60 percent of alcoholics have low blood levels of magnesium||Certain medications: diuretics, antibiotics, and medications used to treat cancer can result in magnesium deficiency|
Magnesium Deficiency Can Lead to Heart Arrhythmias, Coronary Spasms, and Seizures
There's no lab test that will give you an accurate reading of the magnesium status in your tissues. The reason for this is that only one percent of the magnesium in your body is found in your blood. Fifty to 60 percent resides in your bones, and the remaining is in your soft tissues. Since most of your magnesium is stored inside your cells and bone rather than in blood plasma, there are no satisfactory blood tests for assessing it.
That said, some specialty labs do provide an RBC magnesium test, which is reasonably accurate. Other tests your doctor may use to evaluate your magnesium status include a 24-hour urine test or a sublingual epithelial test. Still, these can only give you an estimate of your levels, and doctors typically need to evaluate them in light of the symptoms you exhibit. Early signs of magnesium deficiency may include headaches, loss of appetite, nausea, and vomiting, and fatigue or weakness. However, ongoing magnesium deficiency can lead to far more serious symptoms such as:
- Abnormal heart rhythms and coronary spasms
- Muscle cramps and contractions
- Numbness and tingling
- Personality changes
In her book, The Magnesium Miracle, Dr. Carolyn Dean lists 100 factors that will help you decide whether or not you might be deficient. You can also follow the instructions in her blog post, “Gauging Magnesium Deficiency Symptoms,”9 which will give you a checklist to go through every few weeks. This will help you gauge how much magnesium you need in order to take away your deficiency symptoms.
Your Best Magnesium Source: REAL Food
Most people can keep their magnesium levels in the therapeutic range without resorting to supplements, simply by eating a varied diet, including plenty of dark-green leafy vegetables. However, it is important to remember that the magnesium content of your foods depends on the richness of magnesium in the soil where they're grown. Most soils are now sorely depleted of nutrients, and for this reason, some magnesium experts, such as Dr. Dean, believe that virtually everyone needs to take supplemental magnesium. Organic foods may have more magnesium if grown in nutrient-rich soils but it is very difficult to make that determination.
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. An article in GreenMedInfo lists more than 20 foods that are exceptionally high in magnesium, including the following (for the full list, please refer to the original report). All listed portions equate to 100 grams, or just over three ounces:
|Seaweed, agar, dried (770 mg)||Spices, basil, dried (422 mg)|
|Spice, coriander leaf, dried (694 mg)||Flaxseed (392 mg)|
|Dried pumpkin seeds (535 mg)||Almond butter (303 mg)|
|Cocoa, dry powder, unsweetened (499 mg)||Whey, sweet, dried (176 mg)|
Magnesium Supplements, A to Z
The current government guidelines for magnesium intake among adults call for 300 to 420 mg per day (depending on your gender, age, pregnancy, and lactation), but many people consume less than 300 mg per day. The current research would suggest that many would benefit from a higher intake, about 700 mg per day or even more. Magnesium is lost in sweat during exercise and used up in higher amounts when a person is under stress.
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 bioavailability 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 is likely one 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.
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.
|Magnesium glycinate is a chelated form of magnesium that tends to provide the highest levels of absorption and bioavailability and is typically considered ideal for those who are trying to correct a deficiency||Magnesium oxide is a non-chelated type of magnesium, bound to an organic acid or a fatty acid. Contains 60 percent magnesium, and has stool softening properties|
|Magnesium chloride / Magnesium lactate contain only 12 percent magnesium, but has better absorption than others, such as magnesium oxide, which contains five times more magnesium||Magnesium sulfate / Magnesium hydroxide (milk of magnesia) are typically used as laxatives. Be aware that it's easy to overdose on these, so ONLY take as directed|
|Magnesium carbonate, which has antacid properties,contains 45 percent magnesium||Magnesium taurate contains a combination of magnesium and taurine, an amino acid. Together, they tend to provide a calming effect on your body and mind|
|Magnesium citrate is magnesium with citric acid, which has laxative properties||Magnesium threonate is a newer, emerging type of magnesium supplement that appears promising, primarily due to its superior ability to penetrate the mitochondrial membrane, and may be the best magnesium supplement on the market|
Balance Your Magnesium with Calcium, Vitamin K2, and D
One of the major benefits of getting your nutrients from a varied whole food diet is that you're less likely to end up with too much of one nutrient and not enough of another. Foods in general contain all the cofactors and needed co-nutrients in the proper ratios for optimal health… the wisdom of Nature takes out the guesswork. When you're using supplements, you need to become a bit savvier about how nutrients influence and interact with each other.
For example, it's important to maintain the proper balance between magnesium, calcium, vitamin K2, and vitamin D. An appropriate magnesium to calcium ratio is currently thought to be 1:1, according to Dr. Dean who has studied this issue for the past 15 years. To learn more, please see my recent interview with her, in which she discusses the health benefits of this important mineral.
These four nutrients work together synergistically, and lack of balance between them is why calcium supplements have become associated with increased risk of heart attacks and stroke, and why some people experience vitamin D toxicity. To learn more about this, please see our previous article that delves into this topic in some depth. The above video focuses on the role of vitamin K, specifically.
Preventing Type 2 Diabetes Requires a Multi-Pronged Approach
Type 2 diabetes, which involves loss of insulin and leptin sensitivity, is easily preventable, and nearly 100 percent reversible without drugs. However, preventing this terrible disease requires a multi-faceted approach. Getting adequate magnesium is justone part of the formula. The primary driving force behind obesity and type 2 diabetes is excessive dietary fructose, which has adverse effects on all of your metabolic hormones, so it's important to address the sugar in your diet, particularly fructose. Other critical lifestyle factors include exercise and optimizing your gut flora.
If you've been diagnosed with type 2 diabetes, it is best to avoid the pharmaceutical approach. Diabetes drugs fail to address the underlying problem, and many, like Avandia, can have dangerous side effects. Avandia is linked to 43 percent increased risk of heart attack and 64 percent higher risk of cardiovascular death, compared with other treatments.

Supporting Your Blood Sugar Balance Through Herbs
When it comes to supporting blood sugar balance in the body (as well as your thyroid and adrenals since they are all part of the endocrine system), caffeine may not be your best friend. While those with sluggish adrenal glands and a slow thyroid tend to feel run down and in need of a regular pick-me-up (like coffee and other caffeinated beverages), in the long run, caffeine can do more harm than good while you are healing. I go into the “whys” around caffeine and your blood sugar balance in this detailed post here. In addition to the caffeine, there are other constituents, molds, and mycotoxins that can show up in coffee that some people find they react to.
When I was diagnosed with autoimmune disease and adrenal fatigue, one of the first things that had to go was coffee. To be honest, I never drank coffee because of the caffeine. I drank coffee for the taste and aroma, as well as the emotional experience I felt to my morning cup of joe. For me, it was a ritual that I looked forward to every day (and sometimes multiple times a day). Whether I was brewing it at home or going to my local coffee shops, the experience was one that I clung to tightly.
But, when I was faced with new health struggles, I knew I had to do whatever I could to support my body and give it the tools it needed to heal. Giving up coffee and caffeine was one step in this direction.
And it sucked.
I turned to the coffee substitutes on the market in a desperate attempt to recreate the ritual I had grown so fond of, but nothing ever tasted the way I wanted it to. Nothing ever gave me that same experience that my cup of “real” coffee did. I knew there had to be something better, but I simply could not find it on my health food store's shelves.
Necessity is the mother of invention so that is why I created my own coffee substitutes. They were made with organic, sustainably harvested herbs with zero grains, zero gluten, and zero caffeine. Just herbs. Herbs that not only tasted delicious but supported my body's function, like liver detox, bile production, digestion, etc. In my mind, if I can get something to not only taste amazing but do amazing things for my body, then it's a no brainer!
I sold these pre-made blends on Etsy for awhile and the demand was more than I could keep up with. People literally LOVED these blends and were stunned at how much like coffee they actually tasted. Customers who had been dealing with a variety of chronic illnesses had given up coffee to heal their bodies, but like me were deeply missing their morning cup of joe ritual.
After careful consideration and work with some highly experienced advisors, I decided to stop selling the pre-made blends and instead share my proprietary recipes in the form of an eBook. That way I could arm people with the knowledge and recipes they needed to make their own caffeine-free, gluten-free, grain-free blends in the comfort of their own home.
That is why I created the best-selling DIY Herbal Coffees eBook: A Complete Guide To Making Delicious Herbal Coffees to Support Healing & Stress Relief. Now in its second edition, this ebook features all of my proprietary herbal blend recipes to you can craft a homemade herbal cup of “coffee” at home.
In addition, you get a ton of researched information about coffee's impact on the health of those dealing with issues like adrenal fatigue, blood sugar dysregulation, autoimmune disease, thyroid disease, and any other chronic illness.
Lastly, you get access to your own personal coffee shop. I show you how to recreate your favorite coffee shop drinks and pastries with wholesome, nourishing real food ingredients. No junk here.
