Magnesium threonate is an innovative form of magnesium that acts directly on the brain. Discover the benefits it offers for your memory, sleep, and mood, and why it differs from other forms of magnesium.
What is magnesium and why is it important?
Magnesium is an essential mineral that participates in more than 300 biochemical reactions in the body: from energy metabolism and electrolyte balance, to muscle contraction, bone health, and the functioning of the nervous system.
Although the daily requirement is around 300 mg, many people don't reach this amount. Magnesium deficiency is especially common in older adults, those experiencing chronic stress, or those with diets low in magnesium-rich foods.
Magnesium deficiency: more common than you think
Magnesium deficiency can go undetected in blood tests, as the body draws magnesium from bones and tissues to maintain a stable plasma level. The most common clinical signs include:
-
Persistent fatigue or tiredness
-
Sleep problems
-
Muscle aches or cramps
-
Anxiety, irritability, or low mood
-
Difficulty concentrating or retaining information
Modern diets are often low in magnesium, even if seeds, nuts, legumes, leafy green vegetables, or whole grains are consumed, as impoverished soils have reduced the mineral content of food.
Types of magnesium: are they all the same?
No. The chemical form of magnesium determines its absorption, digestive tolerance, and fate in the body. Some of the most common forms are:

What makes magnesium threonate special?
Magnesium threonate (Magtein®) is the only form of magnesium that has been shown to directly increase magnesium levels in the brain. This is because it crosses the blood-brain barrier via the same pathway as glucose, allowing for active accumulation in neurons.
This property makes it a specific ally for improving cognitive functions, regulating sleep, and reducing anxiety.
Benefits of magnesium threonate
1. Improvement of cognitive function
In a clinical trial of 109 healthy adults, magnesium threonate significantly improved memory, attention, and processing speed. The effect was especially noticeable in those over 50 years of age.
2. Restful sleep and mental clarity
Patients who received supplementation for 21 days reported improvements in sleep quality and quantity, fewer interruptions, and better mental state upon waking (less bad mood, more clarity and energy).
3. Reduction of stress and anxiety
In a study with people aged 50 to 70, magnesium threonate reduced the score on the Hamilton Anxiety Scale by 40% and improved overall well-being.
"Since I started taking it, I've noticed less brain fog and more energy."
Who is magnesium threonate indicated for?
-
People who have difficulty concentrating or remembering information
-
Students and those preparing for competitive exams during a time of high mental demand
-
Adults with chronic stress or mild anxiety
-
Older adults with mild cognitive impairment or insomnia
It does not replace medical treatment, but it can very well complement brain care strategies.
Can pregnant or breastfeeding women take it?
No. Magnesium threonate is indicated exclusively for adults, with the exception of pregnant or breastfeeding women. There are no conclusive studies on its safety in these stages, and current regulations do not permit its use in these groups.
Can taking too much magnesium in supplement form be harmful?
At recommended doses, magnesium supplementation poses no health problems for healthy individuals. The body eliminates excess magnesium through urine, and oral magnesium toxicity is very rare. Excessive accumulation can only occur with very high doses (well above the recommended amount) and in people with kidney failure. It is always advisable to follow the product's dosage recommendations and consult a healthcare professional if you have any pre-existing medical conditions.
