Magnesium L-Threonate Reviews – Benefits, Side Effects, and Dosage!


In this Magnesium L-Threonate Review, we find out the facts and what consumers think! Is this a marvel mineral? Can it improve cognitive function? Is it just hype?

Magnesium L-Threonate is a modern breakthrough super-mineral that has strong evidence of supporting better brain health & cognitive functions. It’s the only magnesium compound that studies have shown to effectively increase the brain’s magnesium levels, which leads to improved memory and cognitive functions. Magnesium is a vital mineral present in the human body that is responsible for the well-being of the brain and the nervous system. The average content of magnesium in the body is 25gm, and it is the component of bones, teeth and nerve formation, cell division and the building blocks of DNA.

It is believed that magnesium is one of the biggest mineral deficiencies in the modern world, which is worrying because magnesium is involved in over 300 enzymatic actions in the body. Deficiency of magnesium can lead to anxiety, fatigue, stress, and neurological problems such as seizure, slow reflexes and motor nerves, reduced cognitive abilities, and mental fog.

Magnesium also contributes to electrolyte balance, protein synthesis, and yielding energy metabolism which is a vital mechanism of the body to be fit. So the presence of a balanced amount of magnesium is essential for the daily function of the body.

Magnesium intake in a standard balanced diet or supplements is lower and complex to absorb, rendering the benefits to be hardly noticeable and decreasing it to a level of severe deficiency that eventually cause mental and nerve problems.


Increased level of magnesium in the brain can enhance memory, learning, focusing, and improvement in levels of stress, anxiety, and normal functioning of the nervous system and muscle response which can improve sleep and prevent lucid dreaming.
Researchers have been trying to find a way to increase the bio-availability of magnesium for a quicker and easier way to transcend the blood-brain barrier which is the area where most of the minerals lose their effects.

Standard magnesium supplements fail to penetrate the blood-brain barrier, and even when taken in recommended doses, often fail to unleash their optimum capabilities, having little effect on the brain and neurological system.

With the introduction of Magnesium L-Threonate, it is now possible to harness magnesium and enhance the level of bio-availability.


Magnesium L-Threonate also known as MgT, Magtein is a form of health supplement chelated to another molecule, which means that the magnesium molecules are bonded to L-Threonate (a vitamin C metabolite), making them more stable and quicker to absorb for increased bio-availability.

A team of neuroscientists from Beijing developed Magnesium L-Threonate. It is not a natural supplement, but when it comes to magnesium, natural is not always better.

Note that natural magnesium is derived from Epsom salt, turned into saline water to be consumed or further harnessed for medical purposes. It is, however, a harsh laxative, and if taken in excess to affect the brain, it could cause severe intestinal dysfunctions. All the magnesium supplements, even the popular and trusted ones, have been clinically enhanced.

L-Theanine is a little-known amino acid that maintains protein balance and boosts the immune system in the body and helps in relaxation of the muscles and the nervous system without adding the sedative effect. It is different from L-Threonate even though they are both amino acids.

L-Threonine is useful for the formation of healthy muscle tissues, nervous system, and even the liver cells. It is not necessarily needed to be taken as supplements because they are sufficiently available in our daily diet as L-Theanine is common in eggs, meat, dairy products, and leafy vegetables.

They exist in combination with supplements for severe deficiencies and to improve stress, sleep, anxiety, and digestive disorders and to make cancer drugs and magnesium supplements more effective.


The requirement for magnesium in the brain is much higher as compared to the need for it in the blood, and it plays a vital role in neurological health such as ADHD, Parkinson’s diseases, depression, anxiety, schizophrenia, Bipolar Disorder, Alzheimer’s disease, acute brain injury, and even addictions.

Magnesium deficiencies are rare in non-vegetarian people, but vegans who do not include enough seedy food like beans and peas into their diet might lack sufficient threonine.
The first symptoms of magnesium deficiency are frequent irritability and sudden mood swings and a leaky gut syndrome which is the result of weak intestinal absorption of allergy-provoking proteins.

Since our body cannot synthesize theanine, the amino acid we take in through our diet converted by the central nervous system helps mitigate the brain chemistry to calm the nerves and the brain.

The use of Magnesium L-Threonate makes it easier to pass through the brain’s protective filter and absorb magnesium and increase the flexibility of the mind and stimulates it to generate fresh brain cells.

Only the L form of theanine which occurs in nature is suitable as a dietary supplement. They are usually available in 500mg capsules and can be taken three times a day by adults. The dosage for children should be given only after consulting a specialist.

Along with L-Theanine, vitamin B6, magnesium and niacin are needed by the body to convert proteins that create amino acid such as glycine and serine which are responsible for calming or exciting the central nervous system.
Therefore, a combination of L-Theanine along with L-Threonate is essential for the full effectiveness of magnesium in the body.


For magnesium, the recommended daily allowance (RDA) is 420mg for men and 320mg for women, but they vary with age-groups.
Though there is no RDA for Magnesium L-Threonate, 1,000mg to 2,000mg per day for practical cognitive benefits is a good rule of thumb.
The recommended dosages for most magnesium supplements are:

  • Children below 13 years: 80-240mg/day
  • Females above 14 years: 300 -360mg/day
  • Males over 14 years: 400-420 mg/day
  • Pregnant/ nursing women: 310- 400mg/day

While this may seem like a large dosage, remember that only a fraction gets absorbed. So 2,000mg of Magnesium L-Threonate will only deliver about 144mg of elemental magnesium, which is roughly a third of the RDA for magnesium.

Taking different forms of magnesium supplements that have different concentrations levels such as Magnesium Glycine and Magnesium Citrate is not harmful and does not post any side effects.


There are no long-term L-Theanine side effects as yet. However excessive use within a short duration may cause a headache, drowsiness and uncomfortable bowel movements.
All magnesium supplements have a common side effect, which is loose motion and laxative effects.
However, antibiotics, blood thinners, osteoporosis, blood pressure medications, and muscle relaxant medicines could create more severe side effects.
Anyone taking a kidney or heart-related medications should also avoid mixing it with any form of magnesium supplements.
L-Theanine with caffeine can charge physical and mental performance but when depended on it, can cause the body to withdraw to fatigue, irritability, and poorer overall cognitive performance if they are not continually administered which is the reason why some people have severe mood swings or lack the motivation to perform physical activities.


  • COGNITIVE It helps in improving learning, short term and long term memory, understanding, and cognitive abilities.
    It had a slowing effect on a standard aging memory making them highly helpful for older subjects who are suffering from Parkinson’s or Dementia.
  • MENTAL Magnesium L-Threonate is good for overall mental health, reducing stress, anxiety, depression and reducing other forms of mental issues, calming the nerves and mental functions.
  • NEUROLOGICAL Since L-Threonate has a relaxing effect, it eases the nerves and is valid for preventing and reducing seizures, and other nerve related problems.
  • PHYSICAL Improves bone density and cardiovascular health strengthen the immune system, controls blood pressure and inflammation clears the digestive tract and enhances sleep.
