Magnesium is an important dietary mineral involved in more than 600 biochemical processes in the body (1). Magnesium boosts our energy and immunity, lowers inflammation and anxiety, improves brain and heart health, supports joint and bone health, and so much more (2-7). There’s just one BIG problem… far too many people are magnesium deficient! With so many magnesium supplements out there, which is truly the “best” one that can help fix this problem?

Today, let’s discuss the 3 forms of magnesium found in our bestselling product, MagEnhance Complete Magnesium Complex. Read on to know more about Magnesium Glycinate, Magnesium L-Threonate, and Magnesium Taurate, and how these three can help support your health!

What’s the right magnesium dosage?

Why are so many people deficient in magnesium?

In the United States alone, as much as half of the population is said to be magnesium deficient. This is partly due to highly processed foods, which is prevalent in Western diets (8). But it’s not just poor diet that’s to blame. The stress and pollution of modern life also leach magnesium from the body. Even more worryingly, there are reasons for this widespread deficiency that’s beyond most people’s control.

According to a 2009 research published in HortScience, fruits and veggies have less magnesium nowadays compared to a few decades ago. This is because modern agricultural techniques fast-track the production of higher-yielding crops in less time. Less time in the ground means less time absorbing important nutrients like magnesium (9). Additionally, this vital mineral is also taken out of our salt and drinking water, thus contributing to the problem as well.

What’s the best magnesium supplement for overall health?

Choosing the best magnesium supplement on your own can prove to be challenging – there are so many forms of magnesium to choose from! Is magnesium glycinate the best one? Or is it magnesium citrate, oxide, ascorbate, orotate, threonate, taurate, or something else? The list goes on and on!

When choosing the best form of magnesium for your needs, it’s important to factor in a couple of points:

  • Is it bioavailable?
  • How much elemental magnesium does it contain?

Determining the magnesium supplement’s bioavailability is important because if this mineral isn’t being absorbed and used, then it’s nothing more than expensive waste! Specifically, inorganic salts of magnesium (such as magnesium oxide) have poor bioavailability compared to organic salts like magnesium glycinate (10). 

On the other hand, elemental magnesium (Mg) refers to the actual amount of magnesium available in the supplement. Since magnesium is highly unstable, it needs to be combined with another molecule to make it stable, hence, the variety of magnesium supplements available.

For example, magnesium oxide has a relatively higher elemental magnesium content at 60.5% but it’s also very poorly absorbed. Meanwhile, magnesium glycinate only contains 14.1% elemental Mg. But because it has better bioavailability, more magnesium ends up being used by the body!

This is where our MagEnhance Magnesium supplement shines. We’ve formulated it to contain 3 of the most bioavailable and effective forms – Magnesium Glycinate, Magnesium Taurate, and Magnesium L-Threonate.

Let’s discuss each MagEnhance ingredient in detail!

MagEnhance Ingredient #1: Magnesium Glycinate

Magnesium Glycinate at a glance (11):

  • Other names: Magnesium Bisglycinate, Magnesium Diglycinate
  • Parent compound: Glycine (an amino acid)
  • Component compound: Magnesium and Glycine
  • Chemical formula: C4H8MgN2O4
  • Molecular weight: 172.42 g/mol
  • Elemental magnesium: 14.1%
  • Chemical structure:
chemical structure of magnesium glycinate
  • Each 3-serving capsule of MagEnhance contains 690mg of Magnesium Glycinate (23% DV)

What are the benefits of Magnesium Glycinate?

Magnesium Glycinate is an orally available magnesium salt of glycine. Bonding or chelating magnesium with glycine significantly improves its bioavailability, making this form highly effective at increasing body magnesium levels.

Its superior bioavailability was demonstrated in a study published on the FASEB journal. Bariatric surgery patients who took 400mg of Magnesium Glycinate for 6 weeks observed an improvement in their plasma magnesium levels, but those who took the not-so-absorbable Magnesium Oxide did not get the same result. The same study also reported that Magnesium Glycinate helped raise blood potassium levels in physically active young people, meaning magnesium is actively retaining and distributing potassium in the body. Also, unlike other magnesium supplements, Magnesium Glycinate is gentle on the stomach (12).

So, what happens when the body absorbs Magnesium Glycinate? Well, the magnesium and glycine molecules separate. They then go on to perform their individual functions.  

As mentioned earlier, magnesium is involved in hundreds of biochemical processes, including DNA and RNA synthesis, cellular repair, and more (1-7). On the other hand, glycine’s functions include enhancing sleep quality as well as various neurological functions. Research also shows that glycine may have a role in preventing and treating metabolic disorders in patients suffering from obesity, diabetes, cancer, chronic inflammation, and cardiovascular disease (13).

Are there any downsides to taking Magnesium Glycinate?

Not really. But there’s a reason why we added two more forms of magnesium in MagEnhance. Magnesium Glycinate can indeed raise body magnesium levels. But unfortunately, it DOES NOT cross the blood-brain barrier, which brings us to the next form on our ingredients list, Magnesium L-Threonate.

MagEnhance Ingredient #2: Magnesium L-Threonate

Magnesium L-Threonate at a glance (14):

  • Patented name: Magtein®
  • Other name: L-Threonic Acid Magnesium Salt (L-TAMS)
  • Parent compound: L-Threonic acid
  • Component compound: Magnesium and L-Threonic acid
  • Chemical formula: C8H14MgO10
  • Molecular weight: 294.5 g/mol
  • Elemental magnesium: 8.3%
  • Chemical structure:
chemical structure of magnesium l-threonate
  • Each 3-serving capsule of MagEnhance contains 1,000mg of Magtein® Magnesium L-Threonate (20% DV)

What are the benefits of Magnesium L-Threonate?

Dubbed the “brain magnesium,” Magnesium L-Threonate is another highly absorbable form of magnesium. The magnesium molecule is bonded or chelated with Threonic acid, a sugar compound derived from ascorbic acid or Vitamin C.

This form of magnesium (patented as Magtein®) was developed by scientists at MIT, Stanford University, and Tsinghua University to cross the blood-brain barrier and increase Mg levels in the brain. Other forms of magnesium cannot pass the blood-brain barrier, but Magtein® can bypass this protective membrane. More magnesium in the brain means a boost in brain plasticity, which allows for better connections between neurons in our brain (15).  

A 2016 study published in the Journal of Alzheimer’s Disease gave older subjects (age 50-70) with mild cognitive impairment either Magnesium L-Threonate or placebo. After 12 weeks, the researchers reported these remarkable outcomes (16):

  • The average brain age of the magnesium group decreased by about 9 years, while the placebo group had little change.
  • There was a significant reduction in cognitive impairment. More specifically, the magnesium group experienced positive changes in four cognitive areas: attention, working memory, episodic memory, and executive function.
  • Both brain and body magnesium levels increased.
  • When it comes to safety, side effects were only classified as mild.

Are there any downsides to taking Magnesium L-Threonate?

Magnesium L-Threonate may help boost your brainpower and enhance learning and memory, but there is a slight downside to this particular form of magnesium. In the study we’ve quoted above (16), the researchers couldn’t get a definitive conclusion on the effects of Magnesium L-Threonate on sleep and anxiety. So, our team added the next ingredient to fill the gap and round up our MagEnhance Complete Magnesium Complex!

MagEnhance Ingredient #3: Magnesium Taurate

Magnesium Taurate at a glance (17):

  • Other name: Magnesium Ditaurate
  • Parent compound: Taurine (an amino acid)
  • Component compound: Magnesium and Taurine
  • Chemical formula: C4H12MgN2O6S2
  • Molecular weight: 272.6 g/mol
  • Elemental magnesium: 8.9%
  • Chemical structure:
chemical structure of magnesium taurate
  • Each 3-serving capsule of MagEnhance contains 630mg of Magnesium Taurate (13% DV)

What are the benefits of Magnesium Taurate?

Magnesium Taurate is formed by combining the amino acid taurine with magnesium. But unlike other amino acids, taurine is not used in protein synthesis. Instead, it helps regulate many functions in the body, including cell development and protection. Taurine is abundant in different organs throughout the body, such as the brain, retina, muscles, and more (18).

Taurine also acts on GABA receptors in the nervous system (19), which is the reason behind its nerve-calming and sleep-enhancing effects. Similarly, magnesium also has a strong affinity with GABA receptors, which is why chelating magnesium with taurine makes it a potent relaxing compound, helping ease stress and improving sleep quality (19).

In a double-blind, placebo-controlled study on elderly subjects suffering from insomnia, the researchers found that magnesium helped improved the following (20):

  • Insomnia severity index, sleep time, sleep efficiency, early morning awakening 
  • The concentration of melatonin, serum renin, and serum cortisol 

Another common health benefit between taurine and magnesium is their effect on heart health and blood pressure:

  • A meta-analysis found that taking 300mg of magnesium daily for 30 days helped increase blood magnesium and reduce blood pressure (21). The same effect (a decrease in high blood pressure) was also observed in obese women (22).
  • Likewise, oral taurine supplementation in hypertensive patients helped reduce hypertension symptoms. Diabetic patients also experienced a reversal in arterial stiffness and brachial artery reactivity (23).  

Because of these complementary health benefits, one study recommended that future research be done on Magnesium Taurate’s potential effects on cardiovascular health, diabetes, and insulin sensitivity (24).

Are there any downsides to taking Magnesium Taurate?

Like Magnesium Glycinate, the only downside to Magnesium Taurate is that it cannot cross the blood-brain barrier. Fortunately, Magnesium L-Threonate helps solve that limitation.
