"Up to 80% of Americans May Not Be Getting Enough of this Essential Nutrient. Where Do You Stand?"*

  •  How Dr. Mercola Magnesium L-Threonate provides the preferred form of magnesium:

    • Our Magnesium L-Threonate delivers 2,000 mg of patented Magtein™ magnesium L-threonate, which has a superior absorption characteristic of any form of magnesium.
    • This preferred form of magnesium in our Magnesium L-Threonate also has high-cellular penetration characteristics, allowing it to cross your blood-brain barrier and penetrate cell membranes.*
    • Unlike other forms of magnesium that can cause gastrointestinal discomfort and loose stools, magnesium L-threonate does not act as a laxative and can actually help to significantly reduce GI discomfort.*

Many people dread growing older because it can be synonymous with occasional forgetfulness, loneliness and a general decline in cognitive and physical capabilities.

Despite being in my 60s, I am the fittest I have ever been.

I may have been able to run faster when I was younger, but I would never trade that for the muscle strength, flexibility and knowledge that I have today.

You may not aspire to reach the same level of fitness as me. I just want you to know that it is never too late to start implementing healthy lifestyle strategies to enhance your physical and mental well-being. There are many different steps you can take…

And those so-called “senior moments?” They are not inevitable. You have more control over your aging than you likely realize!

But there is one thing that goes along with aging that greatly concerns me, and it should you, too.

The Invisible Deficiency That Eludes Even Doctors

Magnesium Level Test
The red blood cell (RBC) magnesium test is more accurate than the standard serum magnesium test.

As time marches on, your body becomes less efficient and effective in absorbing important vitamins and minerals.

So, despite a healthy diet rich in fresh organic vegetables, you may still come up short in certain nutrients.

One nutrient in particular concerns me. And surprisingly, it may not be one you hear much about.

Yet the number of Americans – and many middle aged and above – potentially not getting enough of this nutrient is high. Some experts believe it may be as high as 80%!

That’s a pretty staggering number.

And here’s one of the biggest problems about this nutrient… very little of it actually resides in your bloodstream.

When your body becomes deficient in magnesium, it pulls the magnesium stored in your red blood cells and deposits it into the serum of your blood.

The standard serum magnesium blood test may show magnesium levels as normal even though the red blood cell’s stores of magnesium are depleted.

For that reason, I recommend using the red blood cell (RBC) magnesium test to measure your levels and watch for signs of a potential deficiency. The Vitamin D, Magnesium & Omega-3 Test uses the more sensitive RBC magnesium test.

Why You Don’t Ever Want to Be Short on Magnesium

Magnesium is not a nutrient you want to run low on, despite it being so commonly overlooked.

Here are some key reasons why I feel it's so important for you to pay special attention to Magnesium...

  • It is the fourth most abundant mineral in your body
  • Exists in over 300 different bodily enzymes
  • Is found primarily in your bones (half of your total body magnesium)
  • Plays a role in your body’s normal detoxification processes*
  • Aids your energy metabolism and protein synthesis*
  • Helps guide a large number of physiological functions*
  • Is required by glutathione (the “master antioxidant”) for synthesis*  
  • Is especially valuable for supporting your brain health*

This should give you a good picture of why I believe magnesium is so important. So how can you know if you’re getting an adequate supply?

Some early signs of a potential lack of magnesium in your body include...

  • Loss of appetite and headache
  • Nausea and vomiting
  • Fatigue and weakness

As you can see, many of these symptoms are pretty general and can result from a variety of different conditions. If you suspect you’re low in magnesium, your first course of action is to consult with a healthcare professional.

We also invite you to test your magnesium levels at home with our convenient test kits that not only check magnesium levels but also the levels of other essential vitamins and minerals:

Next, we’ll share some steps you can take to help make sure you don’t fall into the potential majority who may be deficient…

First, Look to Your Diet

There are a number of foods that supply plentiful magnesium, but not everyone includes these in their daily eating.

Organic green, raw vegetables, such as spinach, are excellent choices because the center of the chlorophyll molecule (which provides green veggies their brilliant color) contains magnesium.

Chlorophyll is like a plant's version of our hemoglobin. They share a similar structure but chlorophyll has magnesium plugged in the middle instead of iron.

To help get adequate amounts of magnesium, focus on eating a variety of foods that contain high levels of the mineral. Juicing green leafy vegetables can also be an excellent strategy for obtaining magnesium from food.

Here's a handy chart of specific foods that contain abundant amounts of magnesium for every 100 grams (just over 3 ounces) you consume...

Food (100 grams) Magnesium Content (mg)
Seaweed, agar, dried 770 mg
Coriander leaf (spice), dried 694 mg
Pumpkin seeds, dried 535 mg
Cocoa, dry powder, unsweetened 499 mg
Basil, dried 422 mg
Flaxseed 392 mg
Cumin seed (spice) 366 mg
Brazil nuts, dried 376 mg
Parsley, freeze dried 372 mg
Almond butter 303 mg
Cashew nuts, roasted 273 mg
Whey, sweet, dried 176 mg
Leeks, freeze dried 156 mg
Kale, scotch, raw 88 mg
Spinach 79 mg

Why You Still May Not Be Getting Enough

While some people may be able to maintain healthy levels of magnesium by regularly consuming foods rich in the mineral (like those foods in the chart above), there are certain factors that may prevent you from getting enough:

  • Time – Over time your body faces challenges that can lead to a decrease in absorption of magnesium.
  • Types of food you eat – If you consume mostly non-organic foods, their magnesium levels may be depleted due to chemical fertilizers and pesticides. Levels of magnesium in the soil determine what’s in the food.  
  • Medication – Certain medicines can contribute to a shortage of magnesium within your body.
  • Practicality – For various reasons, it may not be possible for you to consume enough foods rich in magnesium due to availability or personal preferences.

If any of these factors apply to you and you're concerned about maintaining adequate levels of magnesium, you might want to consider a high-quality supplement.

But “high-quality” is the absolute key when deciding on a magnesium supplement. There's such a wide variety of options available to you, it can not only be confusing, but certain supplement combinations can affect the absorption and bioavailability of the magnesium nutrient.

And that's why I decided to take the guesswork out of finding a high-quality magnesium formula and put my team to task to find the best solution for you.

My Must-Haves for a High-Quality Magnesium Supplement

My preferred approach when recommending any supplement is to first compile a list of the essential requirements. With magnesium, here's the list my team and I put together:

For a high-quality magnesium supplement, make sure it:

  • Avoids magnesium stearate – Magnesium stearate is not a source of magnesium. Rather, it is an unnecessary processing aid with no nutritive value, so I prefer to avoid it.
  • Delivers a high-absorption formula – It’s not just about the amount of magnesium found in the supplement. The formula must have high-absorption capabilities.
  • Incorporates high-penetration characteristics – Absorption of magnesium is crucial but it’s also important that the nutrient is capable of penetrating key tissues and cells to be effective. 
  • Helps avoid potential discomfort – Many magnesium products are used as laxatives and antacids. Since this is not the primary focus of what I consider the ideal magnesium supplement, I recommend avoiding any that are specific to stool-softening and so-called indigestion aids. 
  • Provides practical, easy-to-take servings – Supplement servings must be practical to fit into anyone’s busy schedule. Serving size should be straightforward with well-defined guidelines.

Magnesium Supplements – A Minefield of Choices

When searching for a high-quality magnesium supplement, there's such a wide variety available that it can be confusing as to which one is really best for you.

Even more confusing is the fact that there's no such thing as a 100% magnesium supplement. Magnesium must be bound to another ion and that substance can affect magnesium's absorption and bioavailability.

Let's take a closer look at the different types of magnesium supplements available out there and how they compare to one another…

Magnesium glycinate A chelated form of magnesium that tends to provide effective levels of absorption and bioavailability.
Magnesium oxide A non-chelated form of magnesium bound to an organic acid or fatty acid. Contains up to 60% elemental magnesium and has stool-softening properties.
Magnesium chloride/Magnesium lactate Contains only about 12% elemental magnesium but tends to have better absorption capabilities than magnesium oxide which has 5 times the magnesium.
Magnesium sulfate/Magnesium hydroxide These are typically used as laxatives. Milk of Magnesia is an example of this type of magnesium. Since magnesium hydroxide can have up to 42% elemental magnesium, caution is required here not to take too much.
Magnesium carbonate This form of magnesium has antacid properties and can contain from 29 to 45% elemental magnesium.
Magnesium taurate This contains a combination of magnesium and taurine (an amino acid) that together may provide a calming effect on the body and mind.
Magnesium citrate This is a form of magnesium with citric acid which has laxative properties. This can contain up to 16% elemental magnesium.
Magnesium L-Threonate This newer, emerging type of magnesium supplement has shown great promise in absorption, as well as potential tissue and cell membrane penetration.

Confused About Elemental Magnesium? You’re Not Alone!

Possibly the most confusing thing about magnesium supplements is the amount of magnesium in each product.

"Elemental" magnesium refers to the actual amount of magnesium in each supplement form. However, this is by no means the whole story.

It really depends upon what you want from your magnesium supplement…

Just because the supplement contains more elemental magnesium doesn't necessarily mean it's formulated for high-absorption. Plus, there are some types of magnesium supplements that may provide good absorption, but they may also have stool-softening properties that many people dislike.

Magnesium L-Threonate contains the optimal balance of elemental magnesium as it is formulated for absorption and not as a laxative!

Absorption is the key when it comes to this potent mineral that offers exceptional support for your brain, detoxification, energy production and cellular health.*

For every 3-capsule serving, you receive a full 2,000 mg of Magtein™ Magnesium L-Threonate, including 144 mg of elemental magnesium.

What’s so Special About Magtein™ Magnesium L-Threonate?

Brain Health Offers
Magtein offers potential for your brain health*

Magnesium plays an important role in many of your brain's functions, however, most forms of magnesium have low levels of brain bioavailability.

Recently, a group of scientists from Massachusetts Institute of Technology (MIT), including a Nobel Prize laureate, discovered a unique compound called Magtein™.

Magtein™ is the only magnesium compound that has been shown to effectively raise the brain's magnesium levels.*

While other common magnesium compounds generally do not improve brain magnesium levels, studies show that higher magnesium concentrations in the brain and improved cognitive ability occur with Magtein™.*

Animal studies show this can lead to enhanced learning abilities, improved working memory and better short- and long-term memory in both young and aged animals.*

I believe this recent research holds tremendous potential value for your cognitive function.

Magtein™ Magnesium L-Threonate – How This Formula Exceeded My Expectations

For a high-quality magnesium supplement, I strongly recommend Magnesium L-Threonate. Here’s a chart showing the details behind why I think this is such an exceptional formula and how it exceeded my expectations by surpassing the checklist requirements:

Checklist requirement
Completely avoids magnesium stearate?  Yes – I made certain this compound was not part of the formula whatsoever. It's just not a healthy substance you should be putting in your body. Plus, this formula does not contain any genetically engineered (GE) ingredients as well.
Delivers a high-absorption formula?  Yes – With the many types of magnesium supplements available, my team and I selected Magtein™ Magnesium L-Threonate (Magtein®) for its breakthrough absorption characteristics and extensive research.
Incorporates high-penetration characteristics?  Yes – One area where other forms of magnesium supplements tend to fall short involves penetration of tissues and cells. Animal studies have shown how Magnesium L-Threonate has been able to uniquely cross the blood-brain barrier and penetrate cell membranes.*
Helps manage potential discomfort?  Yes – Many forms of magnesium can cause unpleasant gastrointestinal discomfort. In fact as you already know, some magnesium products have the primary purpose of softening stool and acting as a laxative. This is not the case with Magnesium L-Threonate and its consistent formula.
Provides practical, easy-to-take servings?  Yes – Food is not required for absorption so taking it with meals is not necessary. It's always a smart choice to double-check and consult with a healthcare professional when taking any supplement. With our new formula, you only need 3 capsules instead of 4! You can take all 3 at night, or take 2 at lunch and 1 at bedtime with plenty of water, it's easy to take.

I believe by now you can see why I'm so excited about the Magnesium L-Threonate formula. If you're truly looking for a high-quality magnesium supplement to add to your healthy diet, it has my highest recommendation.

Don't Let Poor Lifestyle Choices Put the Brakes on Fully Enjoying Your Life

Now that I’ve passed the age of 60, I'm living proof of how you can live your life to its full potential if you make intelligent lifestyle adjustments as you go.

And this could be one of those times to make another well-informed adjustment. Even though you may eat a diet rich in magnesium, it's still possible to come up short. That's where Magnesium L-Threonate can help.

With Magnesium L-Threonate, you can have a high-quality magnesium supplement with superb absorption – one with a type of magnesium (Magtein) that animal research suggests can cross the blood-brain barrier and penetrate cell membranes.

It’s one of the most practical ways I know of to help balance your overall intake of this vital mineral. And it’s so easy to take regardless of how busy your schedule gets. It’s a simple “add” to support your overall healthy lifestyle strategy.*
